Local models in the Studio Hub tab (Custom folders, LM Studio, and
Local models sections) did not reveal their on-disk path on hover,
unlike the Fine-tuned rows which already do. Each of these rows maps
over a LocalModelInfo with a required path, so pass tooltipText built
from the model name and path via a small shared localPathTooltip
helper, matching the existing FT-row tooltip format.

* Studio: harden the data-recipe and inference consumer loops against pump death
Follow-up to #6643. The same single-unsupervised-consumer pattern the training
pump had lives in two sibling loops, with the same failure mode: one bad event
kills the only thread that updates the in-memory state every UI surface reads,
while the worker subprocess keeps running.
- data_recipe JobManager._pump_loop: a malformed worker log line that makes
parse_log_message raise no longer kills the pump. Guard _handle_event, the
queue read, and the worker-exit finalize, and broaden _drain_queue so a drain
error still finalizes the job instead of leaving it wedged "active" (which also
leaked the workflow-scoped API key until its 24h expiry).
- inference InferenceOrchestrator._dispatcher_loop: guard the routing body so a
malformed response or a mailbox put error can't kill the dispatcher and hang
every in-flight generation (callers key liveness on the subprocess, not on
this thread).
Adds regression tests for both.

* Studio: extend consumer-loop hardening to RAG, hub, auth, and stream-reader paths
Continuation of the data-recipe and inference pump hardening: the same
"background producer updates in-memory state that a single unsupervised
consumer surfaces to the UI" pattern shows up in several more Studio paths,
each able to silently freeze a UI surface while the worker keeps running.
RAG ingestion SSE (core/rag/ingestion.py):
- job_events polled the queue with a blocking get and never noticed client
disconnect or a dead worker, so a closed tab or a producer that died
without emitting a terminal event left the stream hanging. It now polls
with a timeout, emits heartbeats, ends on terminal job status, caps idle
time, and always pops the job registry in finally.
- Added _reap_finished_jobs() and call it from start_ingestion so finished
job state does not accumulate.
Startup reconcile (storage/rag_db.py, main.py):
- reconcile_orphaned_ingestion_jobs() marks ingestion jobs (and their
documents) that were left non-terminal by a previous crash as failed, so
the UI does not show jobs stuck "running" forever after a restart. Wired
in at startup next to cleanup_orphaned_runs().
Hub download watcher (hub/services/download_lifecycle.py):
- _watch() could leave a job pinned "running" if finalize raised. Body is
now guarded: on failure it logs and sets the job to error, and always
invalidates the hf cache scan in finally.
External provider stream (core/inference/external_provider.py):
- read timeout was None (no stall ceiling); set to 300s so a wedged
upstream surfaces as an error instead of an indefinitely hung stream.
Auth store (auth/storage.py):
- Enable WAL + busy_timeout on the auth DB so token validation (read on
every request) and login writes stop serialising on the rollback journal.
Matches studio_db / rag_db / providers_db.
Login rate limiter (routes/auth.py):
- _LOGIN_IP_BUCKETS could grow unbounded under spoofed-IP traffic; cap it
and prune stale buckets, mirroring the per-account bucket handling.
Training progress SSE (routes/training.py):
- Break promptly on client disconnect instead of waiting for the next
yield to fail on a closed socket, matching the export / data-recipe SSE
routes.
llama-server stdout drain (core/inference/llama_cpp.py):
- Broaden the drain guard so an unexpected decode/read error logs at debug
and stops the drainer cleanly instead of escaping the thread.
Frontend stream readers (chat-api.ts, rag-api.ts):
- Wrap the SSE read loops in try/finally + reader.cancel() so early return
([DONE]), thrown errors, and consumer aborts release the reader lock
instead of holding it until GC.
Tests:
- test_training_progress_stream_nan: fake request now implements the async
is_disconnected() the route polls, matching the other SSE route fakes.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: address Codex review feedback on the consumer-loop hardening
Four follow-ups from the automated review, all on code this PR introduced:
- Data-recipe pump (manager.py): a queue read that keeps raising an error
outside the read's narrow catch set (e.g. a broken queue pipe after the
child died) hit the `continue` guard and skipped the dead-worker finalize
below, spinning forever and leaving the job wedged "active" with its
workflow key unretired. On a read failure, fall through to finalize when
the worker is no longer alive. Added a regression test.
- RAG ingestion SSE (ingestion.py): the 5-minute idle cap could end the
stream while the job was still pending/running (a large document spends
minutes in embedding/storing with no per-batch progress event). The route
then sends [DONE], and the client treats a no-terminal-frame end as
completion, marking the document indexed mid-ingestion. Drop the idle cap:
while the worker is alive and non-terminal we keep heartbeating; the stream
ends only on terminal DB status, the None sentinel, or client disconnect.
- Login rate limiter (auth.py): the per-IP path pruned but then added the
new IP unconditionally, so a spoofed-source-IP spray kept _LOGIN_IP_BUCKETS
unbounded and made every new IP pay a full-dict prune scan. Gate the add on
the cap, mirroring the account path.
- Hub download watcher (download_lifecycle.py): if finalize raised before it
reaped (proc.wait) and dropped the worker (e.g. an I/O error draining
stderr), the crash path published a terminal state while the live Popen
stayed registered and kept writing the cache, and the terminal set_job let
claim() admit a retry on the same repo. Terminate + drop the worker before
setting the terminal state.
* Studio: keep login throttling working when the per-IP bucket dict saturates
Review follow-up. The previous cap fix skipped creating a bucket for a new IP
once _LOGIN_IP_BUCKETS was full, returning ip_fails=0. Under a sustained spray
that also fills the account dict, every failure from such an IP then looked
first-seen and _login_blocked had no bucket to enforce, so the cap effectively
disabled throttling once saturated.
Bound the dict with a FIFO eviction instead: if the IP is new and the dict is
full, reclaim expired buckets (rate-limited so a burst of distinct IPs can't
make each failure an O(n) sweep) and, if still full, evict the oldest-inserted
IP. The new IP always gets a real bucket, so a saturating (e.g. spoofed
X-Forwarded-For) spray stays throttled while memory stays bounded. Added a
regression test that saturates the dict and asserts a later IP is still blocked.
* Studio: address Codex review (RAG queue lifecycle, stream error, orphan chunks)
Three follow-ups on the Phase 6 changes:
- RAG ingestion SSE (ingestion.py): job_events removed the per-job queue in its
finally on ANY exit, including an early client disconnect while the worker is
still running. That dropped the worker's later events (the queue is the only
one _emit writes to) and made a reconnect find no queue and receive only
[DONE], which the client treats as completion. Only drop the queue on a
terminal exit (None sentinel / terminal DB status); leftover terminal queues
are still swept by _reap_finished_jobs. Added queue-lifecycle tests.
- External provider stream (routes/inference.py): once the 300s read timeout can
fire, the stream's except path failed the monitor but ended without an error
frame or [DONE], so the chat client saw a bare EOF and saved the timed-out
answer as a successful partial with no error. Emit an SSE error frame (and
[DONE]) on stream failure so the client surfaces it.
- RAG startup reconcile (storage/rag_db.py): marking a half-ingested document
failed left its chunks/fts/vec rows intact, and retrieval filters by scope not
status, so a failed document could still be retrieved and cited. Purge the
document's chunks when reconciling it to failed (the doc row stays for
re-ingest).
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: release the remaining SSE stream readers (training, data-recipe, export)
reviewer.py follow-up. The chat and RAG SSE readers were wrapped in
try/finally + reader.cancel(), but the other three readers built on the same
response.body.getReader() pattern were left without it: streamTrainingProgress,
streamRecipeJobEvents, and streamExportLogs leak the ReadableStreamDefaultReader
lock (held until GC) when the consumer aborts, returns early, or a parse/callback
throws. Wrap each in try/finally + reader.cancel() (export already had a
try/catch, so it only needed the finally). All five frontend SSE readers now
release the reader symmetrically.
* Tighten resilience comments and docstrings
Condense the verbose explanatory comments and internal-helper docstrings added
in this branch to shorter, clearer forms. Comment/whitespace only; verified no
code changed via AST diff. No behaviour change.
* Studio: keep chunks for completed docs during ingestion reconcile
Startup reconciliation flips orphaned (non-terminal) ingestion jobs to failed and
purges the document's chunks so a failed source can't be retrieved. But it dropped
the chunks unconditionally, so a document the worker had already committed as
'completed' before the crash (only its job row left non-terminal) lost every chunk
while still reporting 'completed'. That leaves an empty source that retrieval can't
return and dedup (status != 'failed') blocks from re-ingest.
Only purge chunks when the document UPDATE actually transitions it to failed; an
already-completed document keeps its chunks. Adds reconcile regression tests for
both the completed-doc and genuine in-flight-orphan cases.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: drop a finished RAG job's queue when the client disconnects
job_events kept the per-job queue until it consumed the None sentinel, so a UI
that stops on the terminal event (its reader.cancel aborts the stream before
[DONE]) left the queue registered until the next _reap_finished_jobs sweep; a
batch of uploads followed by idling retained them all.
_run writes the terminal DB status before emitting the terminal event, so on
generator exit, drop the queue when the job's DB row is already terminal (worker
done, nothing to resume) and keep it only while the worker is still running. Adds
a disconnect-after-terminal-event regression test.
* Remove stray async task output files committed by mistake
* Studio: harden login IP throttle and end progress stream on disconnect
Two Codex review items:
Login per-IP throttle: when the per-IP bucket dict saturated, FIFO eviction could
drop a still-hot (blocked) bucket, so an IP could flood the dict with distinct
(or spoofed) source IPs to push out its own bucket and retry as first-seen. Stop
evicting hot buckets; a new IP that can't fit now shares a bounded overflow
counter that still trips the per-IP threshold, so a saturating spray stays
throttled and no live counter is reset.
Progress SSE: on client disconnect the polling loop only broke and fell through
to the unconditional final 'complete' frame, so a buffered or proxying consumer
could read a still-active run as completed. Return from the generator instead.
Adds regression tests for both (spray cannot reset a hot bucket; disconnect while
active emits no complete frame).
* Studio: shard the login overflow counter and stop cancelling chat stream after [DONE]
Two Codex review items:
Login throttle overflow: the single shared overflow counter meant that once a
saturating spray pushed it past the per-IP threshold, _login_blocked returned 429
for every new unbucketed source IP, before credentials were checked -- a global
login denial. Shard the overflow into a fixed array of counters keyed by hash(ip),
so a hot shard only throttles the IPs that map to it while a single source's
repeated failures still concentrate in one shard and stay throttled. Memory stays
bounded and no live bucket is evicted. Adds a regression test that a hot overflow
shard does not block an unrelated IP.
Chat stream: the reader.cancel() in the SSE finally fired even after a natural
[DONE]/EOF. The backend finalizes its api-monitor entry right after yielding the
sentinel (the local pass-through finishes after the last yield), so a client
cancel there can be observed as a disconnect and mark a completed request as
cancelled. Track natural completion and only cancel on an early/abnormal exit.
(No frontend unit test: the Studio frontend has no test harness.)
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: give prep-timeout test fakes an is_disconnected method
The progress stream now ends on client disconnect (await request.is_disconnected()
before falling through to the terminal frame). After merging that into the
prep-timeout tests added later on main, their _FakeRequest/_ReconnectRequest must
provide is_disconnected or the generator raises AttributeError under CI.
* Studio: keep the login overflow throttle when bucket capacity frees up
_login_blocked only consulted the per-IP overflow shard while the bucket dict was
still at capacity. If a slot freed before the 60s window expired (e.g. another
IP's successful login calls _clear_login_bucket), a source counted in a hot shard
stopped being blocked and its next failure got a fresh per-IP bucket, resetting
the throttle the overflow path exists to preserve. Always max in the IP's shard
(shards are empty outside saturation, so it is a no-op in the common case). Adds a
regression test that a hot source stays throttled after a bucket frees.
* Studio: clear a login IP's overflow throttle on successful login
_clear_login_bucket reset the per-IP and per-account buckets on a successful
login but not the overflow shard, so after the dict saturated and an IP was
counted in overflow, a later successful login left those entries behind and the
next failed attempt could immediately return 429.
Store overflow entries as (timestamp, ip) so a source is throttled by its own
count within the shard (also removing cross-IP collateral within a shard), and
drop just that IP's entries in _clear_login_bucket. Adds a regression test that a
successful login clears the overflow throttle.
* Studio: bound the login overflow shard memory under high-cardinality spray
The per-IP overflow tracked failures in a time-pruned deque of (timestamp, ip)
tuples, so a spoofed-X-Forwarded-For spray of distinct one-off IPs grew memory and
the per-check scan with request cardinality for the whole window -- undermining
the bucket cap that exists to bound memory. Replace each shard with a fixed-
capacity dict (ip -> [count, window_start]): O(1) lookups, and when a shard is
full a one-off IP evicts the lowest-count entry (Space-Saving) so memory is hard-
bounded while a persistent attacker keeps a high count and is never evicted. Adds
a regression test that shards stay within the per-shard cap under a 5000-IP spray.
* Studio: purge chunks for already-failed docs during ingestion reconcile
The reconcile chunk-purge was gated on the documents UPDATE actually flipping a
non-terminal doc to failed. A doc the worker had already marked 'failed' before
the crash (job row left non-terminal) was not re-flipped, so its committed chunks
were kept and stayed retrievable/citable, since retrieval filters by scope not
status. Purge chunks whenever the document is not 'completed' (failed, in-flight,
or gone), preserving the completed-doc carve-out. Adds a regression test.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: don't inherit an evicted IP's count onto a new overflow source
When a full overflow shard evicted the lowest-count entry, the new source
inherited that count (Space-Saving base + 1). If a shard was saturated with hot
entries, an unrelated new IP could land at/over the threshold and be 429'd after a
single attempt -- cross-IP collateral despite the per-source-isolation intent.
New entries now start clean at count 1; the only cost is that a heavy hitter that
is the lowest-count entry in a fully saturated shard can briefly reset, which is
preferable to blocking a bystander. Adds a regression test.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: carry overflow failures into a new IP bucket on transition
_login_blocked took max(per-IP bucket, overflow shard) rather than combining them,
so a source could log (threshold-1) failures in overflow during saturation and,
once a bucket slot freed, another (threshold-1) in a fresh bucket within the same
window -- roughly doubling the per-IP limit. When a saturated-era IP first gets a
real bucket, migrate its windowed overflow count into that bucket (and drop the
overflow entry) so the combined failures throttle at the intended limit. Adds a
regression test.
* Studio: reconcile a completed doc's orphaned job to completed, not failed
When a crash left an ingestion job non-terminal after its document was already
committed as completed, reconcile marked the job failed. After restart the upload
UI has no in-memory SSE queue and falls back to getJob(), which treats a failed
job as an indexing failure and removes/toasts a document that is actually
searchable. Mark the job completed (keeping its chunks) when its document is
completed. Extends the completed-doc reconcile test to assert the job status.
* Studio: clamp the overflow failure count migrated into a login bucket
A saturated source could accrue an unbounded overflow count, then materialize
one deque entry per recorded failure when a bucket slot freed, allocating an
arbitrarily large deque under the login lock. Only at-or-above the per-IP
threshold matters for blocking, so cap the count there at the record and take
sites; the migration is now bounded without weakening the limit.
* Studio: keep the RAG job stream alive on a transient status read
The heartbeat poll read the job row unguarded; a momentarily-locked DB would
raise out of job_events, which the SSE route turns into a terminal error frame,
and the UI drops a document whose worker is still running. Treat a failed status
read as non-terminal: heartbeat and retry, and keep the queue so a reconnect can
resume.
* Studio: set busy_timeout before journal_mode on the auth DB
Switching journal_mode needs a lock, so if a refresh-token write already holds
one, journal_mode=WAL raises SQLITE_BUSY and the shared try leaves the
connection on SQLite's default zero lock wait. Set busy_timeout first so the
switch waits instead of failing.

* Studio: require signed capability tokens for /p preview links
The public /p preview routes added in #6486 run model load and chat
generation as the admin user with no authentication. The only gate is the
preview ref, a deterministic outputs-root path (run or run/checkpoint) that
is guessable rather than secret. On a network-reachable Studio (--secure
tunnel or -H 0.0.0.0), an unauthenticated caller who guesses a ref can
consume GPU and probe a private fine-tuned checkpoint.
Make the share link an unguessable, revocable capability:
- Sign the canonical ref with a dedicated server-side secret (HMAC-SHA256,
stored in app_secrets, independent of the JWT/login secret).
- Require a valid token on every /p chat, models, and page request before
resolving a checkpoint or loading a model; missing or invalid tokens get a
generic 404 so the surface never confirms a ref exists.
- Accept the token via ?k= (browser link and preview page) or
Authorization: Bearer (OpenAI-compatible clients).
- Rotate the secret to revoke every outstanding link
(POST /api/settings/preview-links/rotate).
- Clamp preview generation (max_tokens/max_completion_tokens <= 1024, n = 1)
and set Referrer-Policy: no-referrer on the page so the token is not
leaked via Referer.
Training history hands the authenticated owner the signed token, and the
copy-link button builds /p/{ref}?k={sig}.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: honor a lower caller token limit in the preview clamp
Codex review: when only the legacy max_tokens was sent, the clamp left
max_completion_tokens at the 1024 default, and _effective_max_tokens prefers
max_completion_tokens, so a request like max_tokens=16 could still generate up
to 1024 tokens. Derive one effective limit (max_completion_tokens wins, else the
legacy max_tokens) and pin both fields to it so a caller's lower limit is kept.
* Studio: add preview kill switch, rate limit, and revoke-links UI
Follow-ups to the /p preview capability work:
- Public-sharing kill switch: a persisted setting (default on) gates the public
/p surface. When off, every preview request 404s even with a valid token, and
the owner UI stops offering share links. GET/PUT /api/settings/preview-sharing;
enforced in _verify_or_404.
- Per-IP rate limit on the preview chat route: a coarse in-process sliding-window
limiter (20 req/min/IP) returns 429 + Retry-After before the GPU lock is taken.
Client IP honors X-Forwarded-For only when UNSLOTH_STUDIO_TRUST_FORWARDED is
set, matching the login limiter's trust model.
- Settings UI: a "Preview sharing" section with the public-sharing toggle and a
"Revoke all preview links" button (confirm dialog) that rotates the secret.
Tests cover the kill switch (404 when off), the 429 path, the sliding window,
client-IP trust behavior, and the setting default.

* Studio: fix preview-fields sharing arg and refresh sigs after revoke
Codex review:
- P1: get_training_run_detail and update_training_run called _preview_fields
with only output_dir after it gained a required sharing_on parameter, raising
a 500 TypeError once get_run succeeded. Pass get_preview_sharing_enabled() at
both sites; add a detail-endpoint regression test.
- P2: after rotating the preview secret from settings, the history grid still
held stale preview_sig values, so a freshly copied link would 404. Emit
emitTrainingRunsChanged() after a successful revoke so the grid refetches
freshly signed refs.
* Studio: harden preview sharing controls (Codex review)
- Fail closed: a read failure on the preview-sharing kill switch now returns
False instead of defaulting to enabled, so an unavailable settings DB can't
reopen the public surface. A missing key still defaults to enabled.
- Per-IP rate limit behind the managed Cloudflare tunnel: client_ip now honors
CF-Connecting-IP when the socket peer is loopback, so tunneled visitors are
keyed by their real IP instead of collapsing onto the local cloudflared peer.
- GET /p no longer mints key/share_url when sharing is disabled; it returns
sharing_enabled=false so clients don't distribute links that 404.
- Settings UI: toggling public sharing emits the training-runs-changed event so
the history grid shows/hides Copy preview link without a manual refresh.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: harden preview rate limiter and IP keying (Opus review)
From a two-agent review of the PR:
- Rate limiter no longer evicts an active bucket when the table is full: a flood
of distinct keys could otherwise cycle out a throttled bucket and reset its
counter. Evict only aged-out buckets; if the table is full of live clients,
fail closed (deny the new key) instead.
- client_ip keys on the rightmost (proxy-appended) X-Forwarded-For hop when the
trust env is set; the leftmost is client-spoofable. Documented the
append/overwrite-proxy assumption.
- _verify_or_404 checks the capability token before the kill-switch DB read, so
unauthenticated /p spam can't be used as an unbounded settings-DB sink and the
response is identical regardless of the sharing on/off state.
Tests: nested run/checkpoint happy path + wrong-ref rejection, the eviction
fail-closed behavior, and route-level coverage for the rotate / preview-sharing
settings endpoints.

* Studio: stop leaking the auth token through HTML canvas preview frames
The artifact preview frame placed the Studio bearer token in the iframe URL
(?token=) whenever canvas network access was enabled. Untrusted canvas HTML
runs in that frame and can read its own window.location.href, and the
network-mode CSP allows outbound http/https, so the token could be
exfiltrated and replayed against authenticated Studio APIs. The auto-render
HTML cards widened the reach: ordinary or prompt-injected assistant html
fences become a Preview card that opens this same frame, and the render_html
tool path auto-opens it without a click.
Root cause: never put the token in the frame URL. The preview shell is a
static document that only renders HTML posted to it by its embedder, and
frame-ancestors plus the no-same-origin sandbox already constrain it, so the
endpoint no longer accepts or validates the token and selects the network
CSP from allow_network alone. No credential ever reaches the frame.
Defense in depth: only tool-rendered canvases may opt into network mode;
fences auto-extracted from assistant text never do.
* Studio: stop strict canvas frames from self-upgrading to network mode
Network mode is selected from the allow_network query param alone, so untrusted
canvas code in a strict frame could navigate its own iframe to
?allow_network=1; the frame's onLoad handler then reposted the same untrusted
HTML into the now network-enabled frame, giving a no-network or fenced canvas
unauthorized network egress.
Only inject the artifact for loads we initiated (mount or a src change), tracked
by a pending flag set when src changes. A self-navigation also fires onLoad but
is no longer fed, so the upgraded frame stays the inert shell. The strict CSP
default-src 'none' already blocks the child-iframe variant.
* Studio: trim comments in the canvas artifact security fix
Condense the added explanatory comments and the artifact-preview-frame docstring
to one line each while keeping the security rationale. No code change (verified
comment-only).
* Studio: UNSLOTH_NPM_REGISTRY opt-in for corporate npm mirrors (#6491)
studio/frontend/.npmrc pins registry=https://registry.npmjs.org/ as a
supply-chain lock. A project-level pin takes precedence over a user's
~/.npmrc, so behind a corporate firewall that blocks npmjs.org the
frontend bun/npm install hit npmjs.org directly and failed with 403.
Add an opt-in UNSLOTH_NPM_REGISTRY env var (off by default). When set it
is threaded as --registry into every registry-touching install in
setup.sh, setup.ps1 and build.sh (bun bootstrap, bun install + retry, npm
fallback, OXC validator runtime). --registry is the highest-precedence
override for both bun and npm and leaves min-release-age and save-exact
in force, so the default lock is unchanged for everyone else.
On an install failure that looks like a blocked registry, print guidance
pointing at UNSLOTH_NPM_REGISTRY and auto-suggest the mirror already set
in the user's npm config. Registries are never switched automatically.
Also correct the .npmrc comment: the pin does not block an ambient
NPM_CONFIG_REGISTRY env var (npm and bun honor that at higher precedence);
it only guards against a lower-precedence stale ~/.npmrc.
* Studio: make the registry hint reachable under set -e; clean temp log (#6491)
run_quiet_no_exit returns non-zero on failure, which under `set -euo
pipefail` exits the script at the call site before the exit code is
captured, so the new UNSLOTH_NPM_REGISTRY hint never printed on the npm
fallback and OXC validator paths. Guard both with `|| _rc=$?` (the same
idiom every other run_quiet_no_exit caller already uses) so the failure
branch runs, and remove the _FRONTEND_INSTALL_LOG temp file on the
early-exit path.
* Studio: detect the user's mirror outside the pinned frontend dir (#6491)
_suggest_npm_registry / Show-NpmRegistryHint run while the cwd is still
studio/frontend, whose .npmrc pins registry=https://registry.npmjs.org/.
So `npm config get registry` returned that pin instead of the user's
~/.npmrc mirror, and the "Detected a registry" branch was skipped for the
main corporate case (mirror set in ~/.npmrc). Run the lookup from a
directory with no project .npmrc (/ in bash, the temp dir in PowerShell)
so the user/global mirror is surfaced. The NPM_CONFIG_REGISTRY env check
is unchanged and still takes precedence.

* Studio preview: pin adapter, guard streaming submit, robust copy-link
Harden the public per-checkpoint preview surface:
- Pin use_adapter=True in the preview payload sanitizer. Otherwise an
unauthenticated /p caller can POST use_adapter=false, which calls
disable_adapter_layers() on the shared in-memory model without restoring
it; since load_model skips reloads for the same checkpoint, every later
visitor (the page never sends the field) keeps getting base-model output
instead of the fine-tuned checkpoint. Forcing it on also re-enables a
previously disabled adapter and no-ops on merged checkpoints.
- Ignore preview-page submits while a response is streaming. The send
button was disabled but the Enter handler still called requestSubmit(),
so a second request could start before the first reply landed in msgs and
reorder the chat history. Both the keydown and submit handlers now honor
the disabled button.
- Keep the cloudflare-URL polling loop alive across transient startup fetch
errors instead of letting one rejection halt it.
- Build the copy-link from a backend preview_ref (output dir relative to
outputs_root, gated on previewability and the two-segment /p route limit)
so a nested output dir no longer copies a basename-only link that 404s.
Expose preview_ref on training run summaries.
Add route-level security tests (path traversal, payload sanitization,
asset containment, CSP header, HTML title escaping, streaming lock held
until drained) and preview_ref unit tests.

* Studio preview: Safari-safe submit and adapter pin only for LoRA
Follow-ups from cross-browser and route simulations:
- Preview page: send the message from a shared send() helper called by both
the form submit and the Enter key, instead of form.requestSubmit(). The
latter throws on Safari < 16 and older iOS, which broke Enter-to-send there.
Verified across Chromium, Firefox and WebKit with Playwright.
- Only pin use_adapter=True when the resolved checkpoint is a LoRA adapter
(adapter_config.json present); for a merged checkpoint strip it to None.
A merged model has no adapter to toggle, so forcing it on only produced a
per-request "not a PeftModel" warning. The cross-request base-model
contamination fix still holds for LoRA previews.
Add a merged-checkpoint test asserting use_adapter is stripped to None.

* Studio preview: trim verbose comments
Tighten comments across the preview routes, page, checkpoint helpers, and tests
to short single-line notes; drop ones that just restate the code. No behavior
change (verified comment/docstring-only with comment_tools.py check).
* Harden preview routes for PR #6486
- Return a generic 400 detail on a rejected preview path so the public /p
route never echoes the absolute install path (the real reason is logged
server-side instead).
- Strip confirm_tool_calls, session_id and rag_scope in the preview payload
sanitizer so the public surface stays inert regardless of the tool gate.
- Use Path.is_relative_to for the asset containment check, matching the rest
of the codebase.
- Add img-src 'self' and font-src 'self' to the preview page CSP.
- Preview page: on a mid-stream error keep the streamed text, flag the break,
and restore the prompt so the user can retry; drop the unused --font-sans var.

The fade is recomputed on a group's open/close state flip, but the groups
animate their height, so it measured scrollHeight mid-animation and the
fade could vanish at random. Re-measure on the collapsible animationend,
and add the missing pinnedOpen dep to the recompute effect.
Footer padding moves from pt-3 pb-4 to pb-3 with a conditional top: pt-1.5
when the update card is shown so the fade hugs it, pt-2.5 for the profile
on its own. When the update card is shown, shorten the fade above it
(h-10 -> h-3) so the list reads closer to the card.
* Studio: group the project export menu by Combined and Per chat
Replace the repeated (combined)/(per chat) suffix on every export row with a
section subheading, so the rows read Raw JSONL / CSV / ShareGPT JSONL under
Combined and Per chat headings.
* Studio: group export sections with DropdownMenuGroup
Wrap each Combined and Per chat section in DropdownMenuGroup for screen-reader
semantics, and drop the redundant px-3 already set by DropdownMenuLabel.
* Studio: confirm saved Hugging Face token with a tick
Pasting a token and clicking away saved it silently with no feedback.
Show a green tick in the field once a non-empty token is committed and
the input still matches the stored value, so the save is visible. Adds
the tokenSaved label to the en and zh-CN locales.
* Studio: let clicks pass through the saved-token tick
The decorative tick sat over the input and swallowed clicks, so clicking
it would not focus the field. Add pointer-events-none so clicks reach the
input; drop the now-unreachable title and keep an aria-label via role=img.
* Studio: slim the GLM-5.2 thinking menu width
The high|max effort menu has short labels, so drop it from min-w-44 to
min-w-40 for GLM-5.2 only. Other models keep the wider dropdown.
* Studio: keep Preserve thinking menus at full width
Only narrow the effort menu when it has no Preserve thinking row. That
row is longer than the high|max labels and wraps to two lines at the
min-w-40 floor, so gate the skinnier width on no preserve-thinking.
* studio: add sidebar update button (static design only)
Adds a clock-icon update card above the account button in the sidebar footer. Visual/layout only; update detection and click behavior are wired in follow-ups.
* studio: show installed version in sidebar update card + collapse to icon
Replaces the placeholder version with the real installed app version via @tauri-apps/api/app getVersion() (Tauri-only; hidden in browser). Collapsed sidebar now shows just the clock icon instead of hiding the card.
* studio: open Settings About (update section) when the sidebar update card is clicked
* studio: i18n the sidebar update button label and add aria-label
Address Gemini Code Assist review on #6545:
- wrap the hardcoded "Update available" label in t() (shell.updateAvailable,
en + zh-CN), matching the rest of the sidebar
- add aria-label so the collapsed icon-only button has an accessible name

* studio: hide sidebar update card unless an update is available
Gates the card on useWebUpdateCheck so it stays hidden by default on both web and desktop, appearing only when the installed PyPI version is behind the latest release. Includes a TEMP localStorage dev override (devForceUpdateCard) to preview the card where there is no real update; remove before merge. Keeps the i18n label/aria-label; desktop (Tauri updater) detection not wired yet.

* studio: report the true reasoning duration and fix the Stop button for thinking models
For a local GGUF the "Thought for N" label was timed entirely on the client by a
brittle edge-detector, so an always-think model (Qwen3 MTP) that buffers its whole
reasoning and flushes it in one chunk showed "1 second" instead of the real
minute-plus. The client cannot time reasoning it receives atomically, so make the
timing backend-authoritative.
Backend: generate_chat_completion_with_tools measures wall-clock reasoning and
emits a Studio reasoning_summary event (duration_ms) at the moment reasoning ends
-- the first answer token, or end-of-stream for a reasoning-only reply -- for both
the tool-detection pass and the final-answer pass. Timing resets per tool
iteration so the final answer's thinking time wins on the client (which takes the
latest reasoning_summary). routes/inference.py forwards the event in the GGUF tool
stream.
Frontend: parse the reasoning_summary SSE into a _reasoningDurationMs chunk and
use it as the authoritative reasoning duration (last write wins), clamped to >= 0
and guarded to a finite number so a malformed or proxied chunk cannot produce a
NaN label; the persisted value wins for the final "Thought for N" label, with the
previous live timer kept only as a fallback when no metadata arrives.

PR #6364 added a branch that overrode the unsloth owner avatar with the
bundled circle-logo-small.png sticker. Revert it so unsloth uploads use
the live Hugging Face org avatar again, falling back to the colored
initial tile. Upstream re-uploads are unaffected since they still
resolve through provider logos.

* Chat: match reasoning thinking icon to the composer bulb
The reasoning "Thinking..." indicator used lucide's LightbulbIcon while
the composer thinking toggle used a custom bulb glyph, so the two did not
match. Move that glyph into lib/bulb-icon.tsx and use it in both places
so they render the same icon.

* Studio: fall back to anonymous HF browsing on a malformed token
The Discover/Recommended feeds call the Hugging Face JS client
(`listModels`/`listDatasets`) directly from the browser. That client
throws `Your access token must start with 'hf_'` when handed a non-empty
token that isn't a well-formed HF token, instead of falling back to
anonymous access. A single bad value left in the HF token field (e.g. a
placeholder someone typed) therefore takes down the entire discovery feed
even though it works fine with no token at all.
Add `hfApiToken()` to the HF token store, which returns the token only
when it looks like a real `hf_...` credential and `undefined` otherwise,
and route hub-page's four HF call sites through it. Malformed tokens now
degrade to anonymous public browsing rather than erroring. The raw token
is still stored and shown in the settings field unchanged.

Collapse the 11-line JSDoc to a 2-line note and drop the redundant
call-site comment in hub-page. AST signature check confirms code is
unchanged (comments only).

* Studio: refresh chat tour for the redesigned model picker
- Pick a model step describes the Recommended and On Device tabs instead of the old Hub and Fine-tuned split
- Find a model step (was Two tabs) covers Unsloth search vs Search Hub, the format and sort filters, and the OOM tag
- Settings step now anchors to the run settings panel on the right. The old anchor sat on the open settings button, which unmounts when settings opens, so the tooltip lost its target and drifted left
* Add guided tour step for the composer + menu
Polish for the in-chat model picker popover and its guided-tour step.
- Search box placeholder reads Search Unsloth models, matching the Unsloth-only listing.
- Search Hub button shows a Search all models tooltip on hover.
- Floating Eject pill moves 1px lower so it sits closer to the bottom edge.
- Results list max height trimmed by 1px (21rem to 335px) from the bottom only.
- Chat guided tour Two tabs step updated to describe Unsloth-scoped search plus Search Hub for all of Hugging Face.
- Discover defaults to the whole Hub instead of the unsloth org; an explicit
Unsloth choice is still remembered
- Discover models placeholder reads Search all models to match
- Give the Unsloth/All scope pill a min width so it stays readable
* Studio: keep model downloads running across navigation and loads
Downloads started from the chat model selector were tied to the staged
pick lifecycle, so they were cancelled in cases where Hub downloads keep
going. This makes the chat download flow behave like the Hub.
- Leaving the chat route or switching thread/project/new chat now detaches
the staging UI but keeps the in-flight transfer running in the global
download manager (new keepDownload option on abandonStagedModel).
- Staging a second pick no longer cancels the previous pick's download, so
multiple models/variants can download at once.
- Picking a model to download while another model is loading now starts the
download in the background instead of refusing, since a download is
independent of a load.
* Studio: also background-download remote GGUF quants while a model loads
isDownloadableHubRepo (wantManagerDownload) excludes GGUF sources, so an
uncached remote GGUF quant picked from the chat selector while another model
was loading fell through to the 'Another model is already loading' toast
instead of downloading in the background. Treat an uncached remote hub GGUF as
a background download too, matching the staged-pick download path.
Addresses review feedback from gemini-code-assist and codex on PR #6573.
* Studio: only toast a background download once it actually starts
The chat background-download path (used when a model is already loading)
fired the "Downloading in the background" toast unconditionally, but
requestStart can return without starting a job: a cross-transport partial
records a conflict that is only resolvable from the Hub download card, and
a busy sibling variant returns after its own toast. So the user could be
told a download started when none did, with no way to resolve the conflict
from chat.
requestStart now reports an outcome (started/conflict/busy/error). The
chat path only shows the success toast on an actual start and points the
user to the Hub when a transport conflict needs resolving. The Hub card
surface keeps its existing behavior (it renders the conflict resolver, so
it ignores the outcome).
* Studio: report background-download outcome from real job state
The chat background-download toast trusted requestStart's optimistic
"started", but a start can no-op without throwing: startJob finalizes the
job as "error" when the backend refuses or fails apiStart, its peer guard
skips a fresh start, and hasActiveOrPendingStart trips on a snapshot, peer
variant, or pending preflight that is not this request. So the user could
be told a download started when none did.
Derive the outcome from the actual job state of the exact key
(running/cancelling = started, otherwise error/busy), so the toast only
fires for a transfer that is really live.
Also guard against re-downloading the model that is already loading: the
/load flow downloads before it sets the checkpoint, and that fetch is not
a download-manager job, so picking the same id+variant again would start a
second transfer against the same cache. Detect that pick and surface a
"this model is already loading" toast instead.

* Studio: hide RAG embedder from the On Device list
The bge-small-en-v1.5 RAG embedder (and other infra models) were already
hidden from Discover but still showed up in the On Device browse list,
cluttering the user's downloaded models. They are now filtered out of On
Device the same way, while a search that matches still reveals the row so
the user can confirm it is already downloaded.
* Studio: also check path/title when hiding infra models from On Device
isHiddenModelId only saw row.id and row.repoId, but local inventory rows can
have a null repoId and an id that is a hash rather than the file path/name, so
the llama.cpp validation probe (stories260K.gguf) could slip into the On Device
list. Pass the local row's path and title too, mirroring the backend's
_is_hidden_model(m.id, m.path).
Addresses review feedback from gemini-code-assist on PR #6572.
* Studio: exclude infra models from On Device count and dataset list
The On Device hidden-model filter was applied to datasets too, so a
dataset whose id/title/path contained an infra needle (bge-small-en-v1.5,
stories260k.gguf) was wrongly hidden. Bypass the filter for datasets, the
same way Discover and the format filter already do.
The On Device header count and the Cache/Local stat pills still used the
unfiltered row counts, so a fresh install with only the bge embedder
cached read 1 over an empty list. Count visible (non-infra) rows instead,
keeping full counts for datasets.
* Studio: count search-revealed infra rows in the On Device tally
The visible-row counts excluded every hidden row unconditionally, but the
On Device list reveals a hidden row when the search query matches it. So
with only the bge embedder cached and a "bge" search, the list showed one
row while the header and Cache stat stayed 0. Reuse isVisibleInventoryRow
for the counts so a query-revealed row is counted, keeping them in step
with the list.

* studio: let users change their password from Settings
The only day-to-day way to change credentials was the destructive console command
'unsloth studio reset-password' (it deletes auth.db); the in-app change-password
page is the forced first-login flow and bounces non-forced users to /login.
Add a Change password control to Settings > General > Account: a small dialog
that takes the current and new password and calls the existing
POST /api/auth/change-password, then stores the rotated tokens it returns.
Username changes remain out of scope.
The dialog uses authFetch, so an expired access token is refreshed and the
request retried instead of failing with a spurious expired-token error for a user
who left Studio open past the token lifetime. The row is hidden in the Tauri
desktop app, which authenticates via desktop auto-auth with a generated secret:
there is no user-entered password to change there, and changing it would clear
the desktop secret.

* Add HF dataset streaming mode to Studio
* Added default value for datasetStreaming in training-config-store.ts
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Handle None max_steps for streaming validation
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* studio: fast-fail streaming validation and guard incompatible modes
Reject dataset_streaming at the API boundary when hf_dataset is empty,
the dataset is vision/audio, or max_steps is not set. Probe eval split
with get_dataset_split_names before the streaming load so typos fail
immediately instead of mid-training. Guard column_names=None after map
on iterables. Hide the UI toggle for non-text configurations and clear
the stale flag when config becomes incompatible.
* studio: add streaming dataset tests, iterable helper, and streaming template/format support (WIP)
Work-in-progress on top of feat/studio-dataset-streaming-mode (PR #4946):
- new test_training_streaming.py and iterable.py dataset helper
- streaming support in chat_templates.py and format_conversion.py
- additional streaming guards in trainer.py / models / routes
- frontend streaming wiring in params-section and training-config-store
Committed to preserve uncommitted work before merging latest main.
* studio: fix review-team findings for streaming + main merge
BLOCKER: streaming + raw-text/CPT crashed on len(IterableDataset). Guard it in the
start route (reject format_type=="raw" or training_type=="Continued Pretraining")
and in isStreamingSupported (datasetFormat !== "raw").
Also:
- models/training.py: validate hf_dataset/subset/split (charset+length, block ..//);
cap dataset slice indices (le=1e9); note validator ordering
- chat_templates.py: guard _apply_custom_mapping .map() for streaming
- trainer.py: warn when packing+streaming
- training-config-store.ts: persist-migration bump to v11 (standalone datasetStreaming
backfill); add isVisionModel to NON_PERSISTED; toast on silent streamingCompatiblePatch
mutations in the 4 indirect setters
- tests: route rejections (max_steps, raw/cpt), slice cap, unsafe hf_dataset
* studio: enable raw-text/CPT dataset streaming + streaming UX polish
- raw_text: keep the lazy filter but skip len()-based row counting for
IterableDatasets so raw-text / CPT can stream; guard the eval-size log
- routes/trainer: drop the raw/CPT streaming block; add a defensive
not-streaming guard on the eval auto-split (train_test_split)
- dataset-section: streaming toggle is visible-but-disabled and lists the
exact unmet requirement(s) in its tooltip; block embedding models
- training-start-overlay: show "streaming (no full download)" instead of a
stuck download bar for streaming runs
- trim the streaming test suite to the high-value cases
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* studio: address streaming review (MLX/embedding guards, sliced eval split, rehydrate timing)
- routes: reject dataset_streaming for embedding training and on Apple Silicon
(MLX); both loaders materialize the full dataset instead of streaming
- trainer: validate the base eval split name so streaming eval accepts HF slice
syntax such as "validation[:1000]"
- training-config-store: defer the onRehydrateStorage setState to a microtask so
it doesn't hit the store's TDZ during synchronous hydration
- test: streaming start rejects embedding models
* studio: harden HF dataset streaming (column_names, split slicing, empty/eval bounds, gating)
Address a deeper streaming review:
- raw_text: resolve_column_names() guards IterableDataset.column_names=None
(from_generator / unresolved features) so raw-text and CPT streaming no longer
raise TypeError before training
- models/routes: reject HF slice syntax in train_split/eval_split when streaming
(load_dataset(streaming=True) raises "Bad split"); reject mixed sources
(local/S3) and embedding/MLX streaming at the API, not just in the UI
- trainer: an empty post-slice/filter stream fails preflight with a clear message;
streaming eval is capped (STREAMING_EVAL_MAX_SAMPLES) so each eval terminates;
the manual-slice shortcut falls back to a regular load when train_split is sliced
- format_conversion: streaming conversions preflight the first mapped row so
format errors surface before training, not mid-iteration
- frontend: block streaming on Apple Silicon; clear datasetStreaming when a
dataset is detected as image/audio at start
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* studio: fix CI for streaming PR (lint blocker + no-torch sandbox + preflight test)
- trainer.py: drop unused `IterableDataset` import (hoist safety-net blocker).
- test_training_streaming.py: only select real classes (isinstance type) when
locating the trainer class, so a MagicMock-stubbed global is never passed to
object.__new__ (fixes TypeError on the Python 3.10-3.13 jobs).
- no-torch import sandboxes (test_e2e_no_torch_sandbox.py,
test_studio_import_no_torch.py): teach the chat_templates/format_conversion
exec stubs and the full-import-chain copy list about the new `.iterable`
module so the AFTER/runtime cases import without torch again.

* Studio: persistent per-user trust_remote_code approval cache
The consent gate pins each approval to a content fingerprint (sha256 over every
repo .py), but nothing was persisted, so the dialog reappeared on every fresh
load of the same unchanged repo. This adds an on-disk, per-user approval cache
that lets the gate skip the dialog when the same user reloads the same code,
while keeping the safety guarantees intact.
Two-tier validation, both must hold or the user is re-prompted:
- Commit SHA (cheap, one HfApi.model_info().sha, no download): a match means a
byte-identical tree to the approved revision, so the scan/download is skipped.
- Content fingerprint (authoritative): used whenever the SHA is unavailable
(local path / offline) and always recomputed on a SHA miss. A new or edited
.py changes both the SHA and the fingerprint, so it is caught in every mode.
Safety:
- Keyed per subject; one user's approval never auto-runs code for another.
- CRITICAL is never stored or honored (guarded on both write and read), so a
hand-edited store cannot smuggle in an auto-approval.
- The malware (HF unsafe-file) gate stays unconditional.
- Fail-safe: a corrupt store, an unresolvable SHA, or any error degrades to
"ask again", never to "auto-approve". UNSLOTH_TRC_APPROVAL_CACHE_DISABLE=1
turns the cache off entirely.
New module utils/security/remote_code_approvals.py holds the store
(studio_root()/security/remote_code_approvals.json, atomic write, 0600, RLock)
plus the SHA resolvers. Recording happens at the single gate chokepoint when the
caller supplies the matching fingerprint, so subject is just threaded through
inference/training/export (orchestrators, routes, workers). The scan endpoint
returns already_approved so the frontend can skip the dialog on a cache hit.
Tests: new tests/test_trc_approval_cache.py covers cache miss, SHA-match skip,
SHA-moved re-scan, new-file re-consent, CRITICAL never cached (write + forged
read), disable flag, subject isolation, combined adapter+base key, corrupt
store, and no-subject bypass. Full security suite: 101 passed.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Address review: make the approval cache skip only the prompt, never the scan
Codex found that the SHA "no-scan" fast path could run untrusted code without
re-consent. Removed it; the gate now always re-scans and the cache only seeds the
authoritative fingerprint check, so it can skip the dialog but never the scan.
- CRITICAL is hard-blocked on every load (the scan always runs), so a hand-edited
store that downgrades a CRITICAL repo's severity can no longer auto-run it
(P2: do not trust editable severity for SHA approvals).
- The fingerprint covers external auto_map repos, so changed third-party code
always re-prompts even when the primary commit SHA is unchanged; there is no
longer a SHA path that bypasses the fingerprint (P1: external auto_map repos).
- resolve_commit_sha is resolved fresh on every call (no memoization), so a repo
whose default branch moves after approval re-prompts instead of reusing a stale
cached SHA (P1: revalidate mutable Hub SHAs). The SHA is now only a conservative
secondary gate: a fresh resolvable SHA must match the approved revision, else the
seed is withheld; a None (local/offline) falls back to the fingerprint.
- Approvals record the scanner ruleset version (SCAN_RULES_VERSION); the gate
ignores approvals from an older ruleset so reclassified bytes are re-scanned and
re-shown instead of silently auto-approved (P2: invalidate on scan-policy change).
Tests: test_trc_approval_cache.py rewritten around the prompt-skip semantics
(unchanged repo still scans; SHA move / changed code / scanner-version bump /
disable flag all re-prompt; forged downgraded severity still blocks CRITICAL).
105 passed with test_consent_gate.py.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Trim comments to be more succinct
* Keep run-owner subject out of persisted config; serialize approval writes
Threading subject (the run owner's username / API-key id) into the training
config meant _sanitize_db_config persisted it into config_json, which
training-history GET returns to any authenticated user, leaking who started a run
in multi-user installs. Filter subject alongside the token fields; the worker
still receives it from the live config.
The approval store's RLock only guards one process, but approvals are recorded
from separate inference/export/training subprocesses, so concurrent writers could
clobber each other on os.replace and drop an approval (re-prompt). Hold a
best-effort cross-process file lock around the read-modify-write.
* Fail safe on a malformed approval store
A store with the right version but a non-dict shape (e.g. a hand-edited
"subjects": []) passed _load()'s check, then lookup chained .get() on a list and
raised, breaking every remote-code load until the file was removed. Validate that
subjects is a dict in _load(), and tolerate a non-dict per-subject entry in
lookup/record/forget, so a corrupt store fails safe (re-prompt) instead.
* Keep subject out of the MLX W&B run config
_run_mlx_training uploads the whole training config to W&B minus a sensitive set
that only listed hf_token/wandb_token/s3_config, so the authenticated subject
(username / API-key id) was sent to W&B as run config even though DB history
already strips it. Add subject to the W&B-sensitive filter, mirroring
training._sanitize_db_config.
* Tighten the W&B subject-filter comment

* Studio: add Export to GGUF button on finished training runs
A completed run's 'Current Run' tab greys out, so it was unclear how to
export it: GGUF export lives on the separate Export page and there was no
link to it from a run. Add an 'Export to GGUF' button to the run progress
card (shown for completed/stopped runs) that deep-links to the Export page
with that run preselected via a new ?run= search param. The Export page
reads the param, selects the run, defaults to GGUF, and picks the run's
main checkpoint. No retraining is required to export a finished run.
* Studio: fix export deep-link checkpoint preselect and edge cases
Address review feedback on the Export to GGUF deep link:
- Move the main-checkpoint auto-select effect after the model-change reset
effect so it runs last; previously the reset cleared the checkpoint back to
null in the same commit, leaving the field empty on a deep link.
- Reset the applied-run ref when the ?run= param clears (e.g. navigating to
/export via the sidebar) so a later manual reselect of the same run is not
treated as a deep link.
- Trim trailing slashes before taking the run output-dir basename so a path
like /outputs/run/ still yields a name (the button no longer disappears).
* Studio: hide Export to GGUF on runs superseded by a resume
A stopped run whose output_dir was later reused by a resumed run is marked
resumed_later by the backend; its on-disk contents no longer match the older
run's metrics. Since the export deep link selects by output-dir basename,
showing the button on such a run would export the newer continuation instead
of the run being viewed. Carry resumed_later into the view data and hide the
button when set.

The chat and sidebar scroll-fade overlays ended their gradient at the
`transparent` keyword, which is transparent black. Safari 27 Beta
(Liquid Glass) interpolates an opaque colour to transparent black
through a grey midtone, so the fades render as two solid grey bands
(top of the chat and above the composer).
Fade each gradient to the theme colour at zero alpha instead, so every
step keeps the same hue and no grey can appear. Fixes#6457.

* Studio: redesign Select model dropdown to match Hub design
Make the chat Select model picker easier to scan by reusing the Hub
on-device card's visual language.
- Rows now split owner/name, add a param chip, a DotTag format pill,
a tabular size, and a Loaded marker on the active model.
- Hub models / Fine-tuned tabs reuse the Hub's exact .hub-tab-toggle
styling (selectors extended in hub.css to the selector menu).
- Add a Downloaded / Recommended / Custom section toggle on the Hub
tab to filter the list.
- Widen the popover and nudge the scrollbar toward the edge.
* Studio: move section toggle below search, size tabs to label
Put Downloaded / Recommended / Custom under the search bar in their own
row so Hub models / Fine-tuned no longer wrap. The section toggle uses a
smaller font and sizes each tab to its label instead of equal widths.
* Studio: extract pure row-meta helpers into their own module
Move splitRepoLabel, classifyMetaToken, and parseMetaTokens out of
pickers.tsx into row-meta.ts. No behaviour change; keeps the presentation
logic free of React/DOM deps so it is easy to test in isolation.
* Studio: content-size the source tabs and add section icons
Size the Hub models / Fine-tuned tabs to their labels (with side
padding) like the section toggle, instead of stretching full width. Add
a leading download, star, and folder icon to Downloaded, Recommended,
and Custom.
* Studio: stop source tabs stretching and hide empty Fine-tuned tab
The popover is a flex column, so the fit toggle stretched full width;
add w-fit/self-start so it sizes to its content. Also hide the
Fine-tuned tab when there are no fine-tuned models, defaulting to Hub
models.
* Studio: keep only fine-tuned models in the Fine-tuned tab
Local models (LM Studio, Ollama, custom folders) carry source "local"
and already show in the Hub tab's Downloaded / Custom sections, so
exclude them from the Fine-tuned tab and from its visibility count.
Extract the tab rules into source-tabs.ts.
* Studio: show local providers under Downloaded, Recommended first
Show LM Studio and other local provider models in the Downloaded
section in all modes (was chat-only). Put Recommended first and make it
the default section. Add a little more space below the search bar.
* Studio: make Recommended a sortable live Unsloth listing
Replace the static Recommended list (and its collapse chevron) with a
sort dropdown over Unsloth's own models: Recommended, Trending, Most
likes, Downloads, Recently updated. Recommended shows recently uploaded
GGUF/MLX models that fit the device (hidden if they do not); the other
sorts list all Unsloth models, badged but never hidden. Adds a sort
option to useHfModelSearch and a pure recommended-fit helper.
* Studio: size Recommended models from the repo name when metadata is missing
GGUF and MLX repos rarely expose safetensors metadata, so a large model
with no size could pass the Recommended fit check because unknown size was
treated as fitting. Parse the parameter count from the repo id, including
the Gemma E series, and hide anything we still cannot size.
* Studio: detect model capabilities and family from HF tags
Thread tags and the pipeline tag through the model search results and add a
pure helper that infers vision, reasoning and audio plus the architecture
family, falling back to repo-name keywords when tags are absent.
* Studio: add row details and inline section sorting to Select model
Give each model row more detail and make the Hub sections easier to scan:
- Show vision, reasoning and audio badges plus the architecture family tag
on each row, alongside the params, format and size.
- Drop the redundant unsloth/ prefix on the Recommended rows.
- Rename the Recommended section tab to Unsloth and enlarge the section tabs.
- Move the sort dropdown inline to the right of the tabs at a fixed width.
- Add Recent, Size and Downloaded sorting to the Downloaded and Custom tabs.
- Remove the header icons, pad the subheadings, and grow the list height.
* Studio: tune the Select model sort dropdown and trim row badges
- Recommended now lists the most recently created Unsloth repos.
- Narrow the sort dropdown, remove its border, and truncate long labels.
- Tighten the gap between the section tab icons and their labels.
- Remove the architecture family tag from rows since it repeats the name.
* Studio: extract the PillTabs toggle into a shared module
Move the segmented pill toggle out of the model selector into its own file so
the Hub picker can reuse it for a format filter without duplicating the markup.
* Studio: fix Recommended infinite scroll and add a format filter
- Re-attach the scroll observer on each loaded page so a filtered Recommended
list keeps paging until the viewport fills instead of spinning forever with
nothing new appearing.
- Add an All / GGUF / MLX / Safetensors toggle on the Unsloth listing that
filters every sort.
* Studio: default Recommended to Trending, rename Downloaded to On Device, and fade the scroll edge
Sort: default the Recommended view to Trending and add a Name option to
the On Device / Custom sort. Recent now orders by last load time while
Downloaded orders by file date, tracked in localStorage (model-usage.ts).
Formats: show the format filter on all three tabs (Unsloth, On Device,
Custom), exclude mobile GGUF builds from Recommended, and flag GGUF rows
that exceed the device with the same OOM badge as safetensors.
Polish: download-icon badge on already-downloaded Recommended rows, the
hugeicons view stroke-rounded vision badge, Search all models placeholder,
matched popover padding, and a top-edge mask fade once the list scrolls.
* Studio: size GGUF repos from gguf metadata so large ones flag OOM
Repos with no <n>B token in the name (Kimi, MiniMax) had no param count
and so never showed an OOM badge. Request the gguf expand field from
Hugging Face and read gguf.total, so those repos get a param chip and an
OOM badge when they exceed the device budget.
Keep the row name full contrast when over budget (the OOM badge already
signals the fit), shorten the format and sort dropdowns, narrow the
popover, and rename Recently updated to Recent and All formats to All.
* Studio: address selector review feedback
Add WAI-ARIA roving tabindex and Arrow Left/Right navigation to the pill
toggle so only the active tab is in the tab order. Keep the chat-only
GGUF/MLX filter for every Recommended sort, not just Recommended, so
chat-only users do not see unrunnable checkpoints under Trending. Feed
both listings' GGUF hints into repo detection so a tag-only GGUF in
Recommended expands variants instead of loading as a checkpoint.
* Studio: scope Select model search per tab and add an MLX tag
Search is now per section. The Unsloth tab searches the Unsloth HF
listing only, On Device filters downloaded and LM Studio models by name,
and Custom filters custom-folder models, each with its own empty state.
MLX repos get an MLX pill mirroring the GGUF tag. Downloaded quants in
the Unsloth and search lists get the same delete action as On Device.
Also: revert the model name to normal weight, narrow the popover to
558px so the format and sort dropdowns sit one gap-2 from the tabs,
tighten the dropdown menus to match the Projects activity Select, and
make the empty On Device state name the active format filter.
* Studio: show local ./models on the On Device tab so they stay selectable
Models under the local models directory (source models_dir) flow in as local
models but were dropped from every list: filtered out of Fine-tuned and never
re-added by the Hub picker, which kept only LM Studio and custom-folder
sources. Capture them in the local refresh and render a Local models group on
the On Device tab, with the same format, search, and chat-only GGUF rules as
the other local groups.
* Studio: add a Hub button beside the Select model search bar
Adds a Hub button next to the search bar that opens the full Hub Discover
page to browse more models. Styled like the section tabs (rounded, no
border, soft shadow with a faint top layer) and darkens on hover. Also
nudges the format and sort dropdown chevrons a touch toward the edge.
* Studio: align Select model padding and tighten the format pills
Sizes the popover to the tab cluster so the left and right padding match,
and drops the top row below the rounded corner so the Hub button lines up
with the Trending dropdown. Gives the Hub button a fixed width, lets the
list scrollbar sit inside the box, and shrinks the format pill dot with a
tighter dot-to-label gap.
* Studio: label the Hub button Search Hub and match the dropdown width
Renames the button to Search Hub, sets its width to the format and sort
dropdown width so it lines up above them, and tightens the icon gap.
* Studio: drop the vision and reasoning row badges to declutter
Removes the vision and reasoning capability icons from the model rows so
they read cleaner. Audio is kept.
* Studio: add a safetensors pill, hide diffusion models, eye on Vision
Gives safetensors rows a format pill and size so their meta matches GGUF
and MLX, drops image and video diffusion models from the listing since they
cannot run in chat, and shows an eye icon next to the Vision tag. Also
removes the em dashes from the Projects export and import labels.
* Studio: gate recommended folders on real weights and polish the selector
Only show a Recommended chip once the well-known dir actually holds
weights, so an empty LM Studio or Ollama scaffold no longer suggests
itself. _dir_has_downloaded_model checks for a GGUF/safetensors file or
a non-empty Ollama manifests store, with a bounded walk.
Selector polish: round the popover and option menus a touch more,
lighten the OOM badge in dark mode, soften the inner dropdown shadow,
even out the padding, and lift the toggle track and field triggers so
their edges read against the popover.
Also catch CogVideoX in the diffusion name fallback.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: align the dark Select model panel with the sidebar
Match the popover, fields, dropdowns, tab toggle and row states to the
sidebar surface and accent so the dropdown reads as one piece in dark
mode. The active tab pill and Search Hub button sit a touch lighter
than the track, and the inner option menus drop their drop shadow for a
flatter look. Light mode is unchanged.
* Studio: re-derive the Select model tab on open
The picker remounts each time the dropdown opens, but the source tab
state did not, so a persisted fine-tuned or connected selection that
only lands in its list after an async load would reopen on Hub. Reset
the active tab to the selection-derived default on the open edge, while
still letting the user switch tabs freely within a session.
* Studio: fold Custom into On Device and polish the picker
Merge the Custom tab into On Device so custom folders sit right below
the downloaded models, with a folder shortcut on the group header.
Rename the first Hub tab to Recommended, give the format dropdown
colored dots, even out the tab row spacing, and tighten the popover
width. Align the folder browser with the app dialogs (soft surface,
roomier padding, green confirm, grey hover).
* Studio: fix On Device controls and nudge the folder browser close
The Hub redesign merge dropped the old Search Hub button styling, so the
On Device search row rendered flat. Point the search input and Search
Hub button at the shared .field-soft surface so they match the rest of
the Hub controls, and lift the folder browser close button slightly.
* Studio: run the Select model search on the Hub search stack
Point the picker at the Hub's useHubModelSearch and useHubInfiniteScroll
instead of its own useHfModelSearch/useInfiniteScroll, scoped to unsloth
so the listing matches the old one. Both the search and the recommended
feed now share the Hub implementation, so there is one search path. The
Hub result folds GGUF params into totalParams, so the dead ggufParams
fallback is dropped.
* Studio: trim the recommended sort to Recommended, Trending, Recent
Drop Downloads and Most likes from the sort dropdown.
* Studio: give the section tabs room off the rounded edge
The fit-mode toggle wrapped the tabs with no inset, so On Device sat
tight against the rounded-full edge. Add a small horizontal inset and
widen the popover a touch to fit it.
* Studio: drop the legacy HF search hooks for the Hub ones
Migrate the training model and dataset sections, export page, onboarding
steps and recipe dataset combobox off useHfModelSearch, useHfDatasetSearch
and useInfiniteScroll onto the Hub equivalents, scoped to unsloth so the
listings match. The picker reads recommended param counts off the search
results it already has instead of a separate fetch. Removes the duplicate
search stack: use-hf-model-search, use-hf-dataset-search,
use-hf-paginated-search, use-infinite-scroll, use-recommended-model-vram
and the old lib/hf-cache.
* Fix model selector section toggle proportions
Remove the fit-mode track inset so the active pill sits flush to the
track edge, matching the Hub's segmented controls.
* Tighten model selector width and tab padding
Reduce the popover width so the right edge aligns with the row, and
widen the fit-mode tab padding so On Device clears the track edge.
* Refine Recommended formats, sort width and tab padding
Recommended now suggests GGUF anywhere and MLX only on Mac, never
safetensors. Size the sort dropdown to its label so Recommended no
longer truncates, and match the On Device trailing gap to the active
pill's leading inset.
* Flush section toggle and match dropdown font to Search Hub
Drop the trailing track pad so the active pill fits the track exactly
at either end. Size the sort and format dropdown text to text-xs like
the Search Hub button, and clip long labels without an ellipsis.
* Fix sort menu checkmark overlap and lock dropdown widths
Keep the option's right padding so the selected checkmark no longer
overlaps the label, and let the open menu expand to fit it. Set the
format and sort triggers to a fixed width matching the Search Hub
button so they always line up.
* Keep section toggle and dropdowns on one row
Drop the wrap and size the Search Hub button, format and sort dropdowns
to a shared 100px so they stay equal width and fit on one row without
widening the box.
* Studio: pre-load inference settings dialog with native context
Add a gear on downloaded GGUF quant rows that opens a settings dialog
to adjust inference parameters before loading a model:
- Context length, KV cache dtype, speculative decoding and tensor
parallelism, all written to the runtime store the load call reads.
- Settings can be remembered per model in localStorage.
- The context slider ceiling and "Model supports up to N tokens" come
from the model's native context, read from GGUF metadata and returned
by /api/models/gguf-variants once a variant is downloaded.
Also drop models Studio can't run for chat (diffusion, image, video)
from the recommended feed and Hub search, plus minor selector polish
on row hover padding, Search Hub and dropdown widths, and tab spacing.
* Studio: model selector polish and memory-aware load warning
Search and listing:
- Drop the "Recommended" and "Hugging Face" section labels while
searching so results read as one list; keep the format and sort
dropdowns visible so search results can still be sorted and filtered.
- Request gguf metadata in the Hub listing so GGUF repos report a
parameter count, restoring the OOM badge for repos without a size
token in the name (Kimi, MiniMax, GLM).
Load settings dialog:
- Warn when weights plus the KV cache at the chosen context exceed
available memory. The KV size is sized by the backend's
architecture-aware estimator via a new kv-cache-estimate endpoint;
the budget uses VRAM plus system RAM. Best-effort, no warning on
failure or on auto context.
- Context Length placeholder reads "auto"; dark background slightly
lighter.
Other:
- Clicking the Custom Folders header opens the folder browser; its
title now reads "Select folder to detect models".
- On Device sort lists Downloaded last.
- Smaller chat template editor font; rounded wrapper clips the prompt
and template editor scrollbars so the right corners stay round.
* Studio: fix load dialog memory warning budget and KV dropdown width
- The memory warning never fired without a discrete GPU. useGpuInfo
returned zero system RAM in that case, so the budget was always zero.
Surface system RAM even when no GPU is present (Mac unified memory),
and have the load dialog read memory directly instead of through props.
- Give the dialog fields shrink-0 so the KV Cache Dtype value (e.g.
q8_0) is not squeezed and clipped by the row.
* Studio: fold fine-tuned models into On Device tab
Remove the Hub models and Fine-tuned source tabs. Fine-tuned models now
show as a section in the Hub tab's On Device view, above Custom Folders,
with the Train icon and a collapse toggle. The section only appears when
the user has fine-tuned models. With no external providers the lone Hub
tab hides its own toggle.
Also: tick-circle Show hidden checkbox and drop the divider above Eject;
keep run settings load params (KV cache dtype, speculative, tensor
parallel) from being clobbered by a mid-load status poll.
* Studio: stage load settings in the sidebar with a Load on selection toggle
Replace the pre-load settings popup with a staging flow in the Run settings
sidebar. The gear on a downloaded quant row now stages the model and opens
Run settings with Load model and Cancel buttons, so options like context
length, KV cache, speculative decoding and tensor parallelism are set before
the model loads. A "Remember these settings" tick reuses them next time.
Add a global Load on selection toggle in Settings, Chat tab (default on).
On: Unsloth auto-picks the best settings for your hardware and loads on
selection. Off: picking a model stages it in Run settings to customize first.
The gear always stages, regardless of the toggle.
Other polish in this change:
- Fine-tuned models live under the On Device tab, with a train icon on the
header that jumps to the Fine-tuned section.
- Default to the On Device tab when downloads exist, otherwise the last used
section.
- Standard Unsloth tooltips on the train, folder and gear icons.
- Request the gguf param count on every Hub listing fetch so Kimi, MiniMax
and GLM show a size badge.
- Search Hub hover state, scrollbar position and minor spacing fixes.
Remove the old inference load settings dialog.
* Studio: always show the fine-tuned shortcut and smooth out the picker
- Fine-tuned section and its train shortcut now always show on On Device,
with an empty state when no fine-tuned models exist yet.
- Folder icon on the header jumps to Custom Folders instead of opening the
browse popup, matching the train shortcut.
- Folder browser keeps the list mounted and dims it while refetching, so
toggling Show hidden or changing folders no longer flashes.
- Drop the tooltip hover grace area in the picker so moving between the
train, folder and gear icons switches the tooltip at once.

* Studio: add quantization display options and drop the fine-tuned empty text
- Settings, Chat: 'Expand quantizations' toggle. On expands every On Device
GGUF model's quantizations by default; off keeps them behind a click
(default).
- Settings, Chat: 'Show all quantizations' toggle. On lists every quant
including ones not downloaded (default); off shows downloaded only.
- Remove the empty-state line under the Fine-tuned header; the header still
shows on its own.
* Studio: let expanded quantizations collapse on click and split the On/Off help
- With Expand quantizations on, clicking an On Device model now collapses or
re-expands its quantizations. The collapse state is in memory only, so it
resets on reload and when the setting is toggled.
- Put the Off sentence on its own line in the quantization setting descriptions.
* Studio: reorder chat settings and rename the model section
- Rename the Models section to Select model settings and move it above the
Chat menu section.
- Trim the section and Load on selection descriptions.
* Studio: tighten the On/Off lines in the model setting descriptions
Use a line break instead of separate spans so the On and Off lines sit on
consecutive lines without the extra paragraph gap.
* Studio: top-align the Load on selection toggle
Add an alignTop option to SettingsRow and use it so the toggle sits at the top
of the row next to the label, not centered against the tall description.
* Studio: put the gear hint and example chip on one line
Move the gear example chip inline with its label so it reads as a single line
instead of wrapping onto its own row.
* Studio: move the New badge from API keys to Chat settings
Add the New badge to the Chat settings tab and drop it from API keys.
* Studio: line the Load on selection toggle up with the first description line
Offset the top-aligned control past the label row so it sits next to the On
line instead of the label.
* Studio: label the chat menu item Chat with Files (RAG)
Rename the Chat with Files entry in the chat menu settings to clarify it is RAG.
* Studio: drop the pill around the gear example so it fits on one line
Remove the background and padding from the gear example chip so it sits inline
with its label at a lower height.
* Studio: fold the gear example into the description line spacing
Render the gear example inline in the same text block so its line spacing
matches the On and Off lines instead of an extra flex gap.
* Studio: scope Show all quantizations to On Device only
Gate the downloaded-only filter on an onDevice flag so Recommended and other
browse lists always show every quant, and note On Device in the setting copy.
* Studio: tidy On Device GGUF rows
- Drop the redundant Quantizations subheading under On Device models.
- Relay GGUF vision support up to the model name as a Vision badge instead.
- Drop the repo size from On Device GGUF model rows since the quants already
show their size.
* Studio: pin the eject button and tidy General settings
- Move Eject loaded model out of the scrollable list into a centered footer so
it stays in view no matter how far the list is scrolled.
- Space out and center the gear example in the Load on selection description.
- General: drop the duplicate Unsloth version section, move llama.cpp
notifications above Helper LLM, and note new models in its description.
* Studio: add left padding before the gear example
Nudge the gear example away from its label with a small left margin.
* Studio: make the eject footer a sticky bar over the list
Pin Eject loaded model to the bottom of the scroll area with the menu
background so rows scroll under it, and drop the divider line.
* Studio: drop the eject footer background, keep it a sticky button
Make the sticky eject a centered transparent button so it coexists with the
rows scrolling behind it. The wrapper ignores pointer events so only the button
is clickable.
* Studio: give the eject button a solid background
Add the menu background, a border and a soft shadow to the sticky eject button
so it reads as a floating button over the list.
* Studio: restore the eject footer block, keep hover on the button only
Bring back the full-width menu background behind the sticky eject footer, but
keep the button compact and centered so the hover stays on the button.
* Studio: show the vision badge on On Device rows without expanding
- cached-gguf listing reports has_vision (mmproj present), so the badge shows
on the model name without opening the quantizations.
- Make the vision badge icon-only with a tooltip: "This model can process
image inputs". Falls back to the expander-reported value on older backends.
* [pre-commit.ci] auto fixes from pre-commit.com hooks

* Download selected models through the Hub download manager
* Add Other models section for non-Unsloth downloads
* Add directions icon and shortcut for Other models section
* Space out subheadings and gate Other models on non-Unsloth downloads
* Use direction-right icon for Other models
* Use flag icon for Other models
* Widen Connected menu so dropdowns align with Search Hub
* Model selector: truncate long quant labels and tidy layout
- Hub GGUF card: truncate long file-path quant labels with an ellipsis
instead of overflowing the row.
- Connected layout: left-pack the dropdowns and size the box so the last
dropdown's right gap matches the pill's left gap, with Search Hub on its edge.
- On Device: show MLX/Safetensors with the size on non-GGUF rows.
- Connected list rows use the same grey hover as the tabs; the selected
section tab no longer shows a hover change.
* Model selector: drop stale custom section on restore
A persisted custom section value no longer maps to a tab, so restoring it
opened the picker to an empty view. Fall back to recommended instead.
* Model selector: align the non-connected search bar with the All dropdown
Nudge the non-connected box width so the search bar's right edge meets the
All dropdown, which lands Search Hub on the last dropdown's edge.
* Studio chat model selector: remember last tab, route non-GGUF downloads through Hub, stack overlays
- Restore the last Hub section (Recommended / On Device) on every open instead of always snapping to On Device when downloads exist.
- Route uncached non-GGUF repos (safetensors / MLX) through the Hub download manager via a snapshot download, so every model download shows in the bottom-right indicator and follows Load on selection like GGUF.
- Allow safetensors in Recommended on Mac (they run locally there now), and honor the Safetensors format filter instead of dropping it via the recommendation default.
- Stack bottom-right overlays in one column so the download panel and banners never overlap.
- Add evenly spaced divider lines between the On Device subheadings.
- Pad the bottom of the list so the floating Eject pill never covers the last row.
* Studio downloads panel: widen left padding on header and rows
Bump the left inset to pl-4 while keeping pr-3 so the collapse and cancel buttons stay put.
* Studio: update cached-gguf route tests for the has_vision field
list_cached_gguf now returns has_vision per row (vision badge on On Device);
the expected dicts were missing it. True for the mmproj vision repo, False elsewhere.
* Studio: keep MLX/safetensors selectable in chat-only Mac search
The empty Recommended view allows GGUF plus MLX/safetensors on Mac, but the
curated and HF search lists dropped non-GGUF in chat-only via a GGUF-only filter,
so typing a query hid runnable Mac models. Reuse isRecommendableFormat in both
lists so search matches the empty view (chat-only non-Mac stays GGUF-only).
* Model selector: restore global model search and fix GGUF/device-fit regressions
- Search: training, export and onboarding pickers searched only the unsloth org
on a typed query. Restore the prior behavior (global Hub search with unsloth
floated first when a query is typed, curated unsloth listing when empty).
- Recommended browse: the GGUF/MLX-only gate ran before the format filter, so
the Safetensors filter and the Trending/Recent sorts always came back empty.
Apply that gate only for the Recommended sort and chat-only mode.
- GGUF metadata: request the gguf expand field through listModels so repos with
no size token in the name (Kimi, MiniMax, GLM) report a param count for the
size and OOM badge.
- Local GGUF: custom-folder and standalone ./models/*.gguf files now load
directly with the GGUF marker instead of dead-ending in the variant expander,
and scanned GGUF folders are classified via a backend model_format hint.
- Device fit: use system RAM in the budget on unified-memory hosts, and keep MLX
rows selectable on chat-only Macs.
- kv-cache-estimate: resolve the quant from the snapshot-relative path, skip MTP
drafter files, and prefer the most complete snapshot (mirrors the variant
scanner). Bound the Ollama manifest walk.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Model selector: classify suffixless local GGUF folders consistently
Complete the model_format plumbing so a GGUF folder is detected and loaded
through the same GGUF path that the format filter already uses:
- _scan_models_dir: a config.json no longer disqualifies a folder whose only
weights are .gguf, so HF GGUF repos shipping a config still classify as GGUF.
- _scan_lmstudio_dir: emit model_format for every GGUF row (LM Studio dirs
rarely carry a -GGUF suffix), via a shared _dir_model_format helper.
- Custom Folders and LM Studio rows: use localModelIsGguf (the same helper the
filter uses) so the row label, expand-vs-direct-load, and isGguf flag agree;
a suffixless GGUF folder no longer filters as GGUF but loads as non-GGUF.
Adds tests/test_local_model_format.py covering the classification rule.

* Studio model selector: tighten section spacing
Trim each subheading's gap to its rows (pb-1.5 to pb-1) and pull the On Device
heading block tight to the controls while Recommended keeps a little top room.
* Hub: format filter fix, sort defaults, avatar and layout polish
- Format dropdown now filters the feed's Latest list too, so the default
GGUF hides fp8/safetensors and picking a format changes the rows.
- Latest Unsloth Models sorts by newest created, not recently updated.
- Sort dropdown order: Newest, Trending, Most downloads, Recently
updated, Most likes.
- Unsloth uploads with no upstream provider logo show the Unsloth avatar
instead of a colored initial.
- Owner scope pill gets a little more room before the chevron.
- README detail column lines up with the top bar (both-edges gutter).
- Long file-path quant labels truncate instead of overflowing the row.
- Model list keyboard nav no longer clips the focus ring.
- Run settings sheet: restore the Remember settings toggle and larger
Load/Cancel buttons on the staged load flow.
* Hub: hide the RAG embedding model from browse previews
The Hub discover feed and chat model selector pull from the Hugging Face
listing on the client, which the backend _is_hidden_model filter never
touches, so the RAG embedder (unsloth/bge-small-en-v1.5-GGUF) and the
llama.cpp validation probe leaked into the lists.
Added isHiddenModelId mirroring the backend needles and filtered it out of
the discover rows, the trending feed, and the selector's recommended and
Hugging Face search lists. Per-repo file and download views are untouched,
so the model is never deleted and a reinstall still shows it as already
downloaded.
* Studio: skip hidden dirs when checking a folder for downloaded models
_dir_has_downloaded_model walked the tree with rglob("*") bounded by
max_entries. rglob yields entries in arbitrary order and counts every one, so a
model directory that also holds a large hidden subtree (.git/.cache/venv) could
exhaust the budget before reaching the real weights and falsely report no model,
hiding a valid Recommended-folder chip. Replace the generic-weights pass with a
bounded BFS that skips hidden directories so their entries can't starve the walk.
Adds a regression test (50-entry .git beside the weights, max_entries=10).
* Fix/adjust model selector handling for PR #6364
* Studio: address codex review on the staging/recommended-folder paths
- chat-page auto-load: selectModel only clears pendingSelection on success, so a
failed auto-load left the hidden stage (and its edited load knobs) behind.
Abandon the stage when it still matches the failed pick.
- model picker: count fine-tuned rows in the On Device empty check so a
fine-tuned-only tab no longer shows a false 'No models on device' message
above the Fine-tuned section.
- general settings: add the remembered per-model load settings key to PREFS_KEYS
so 'Reset all local preferences' actually clears it.
- recommended-folders: recognize PyTorch .bin weights (gated by the scanner's
weight-name prefixes) so a .bin-only model folder still earns a chip; add tests.
* Studio: name-gate .bin weight detection and complete selector preference reset
Follow-up to the codex review on the model_format/recommended-folder paths:
- _dir_model_format and _scan_models_dir treated any .bin (incl. tokenizer.bin)
as a non-GGUF weight, so a suffixless GGUF folder shipping a companion .bin was
misclassified as a plain checkpoint and routed through the wrong load path.
Factor the scanner's weight-name gating into shared _is_weight_bin /
_has_non_gguf_weights helpers and use them everywhere (also in
_dir_has_downloaded_model).
- PREFS_KEYS was missing the new 'Select model settings' keys (load on selection,
expand/show-all quantizations), so 'Reset all local preferences' left them set.
- On Device cached search dropped the active format filter while a query was
typed; keep matchesFormatFilter applied so the format dropdown stays consistent.
Adds tests for the tokenizer.bin vs weight-.bin classification.

* Studio: validate Ollama blobs, gate staged context, honor RAM budget on no-GPU hosts
- recommended-folders: only count an Ollama dir once its manifest resolves to an
on-disk model blob, so a failed/pruned pull no longer surfaces an empty chip
- GGUF variant click: only seed the staged contextLength for already-downloaded
picks, so choosing an undownloaded quant from a partially cached repo still
starts its download (the staging effect short-circuits on a known context)
- device fit: classify GGUF variants against the system-RAM budget on no-GPU /
unified-memory hosts instead of reporting everything as fits, and pass
systemRamGb to every variant expander regardless of gpu.available
* Studio: scope Hub search to Recommended, fix staged non-GGUF settings, keep local MLX on Mac
- model picker: only run the Hub search hooks on the Recommended section. On
Device / Connected render local data, so typing there no longer fires HF
requests or a spinner and the local/offline flow is preserved
- chat settings: when a pick is staged, decide the GGUF-only controls from the
staged model's type, not the currently loaded model's. A staged non-GGUF Hub
repo no longer inherits a loaded GGUF's context/KV/speculative controls
- On Device: keep local MLX builds in ./models selectable on Mac (chat-only ran
GGUF/MLX only, but the filter dropped MLX before the format toggle)

* studio: persist personalization (profile + theme) server-side
Profile name/nickname/avatar and appearance (theme) were stored only in the
browser's localStorage, so every browser or device that connected to the same
Studio started from defaults and forgot the user's personalization.
Persist them server-side (single-account, stored as one JSON blob in
app_settings) so they follow the account:
- utils/personalization_settings.py + GET/PUT /api/settings/personalization,
with validation (theme/shape enums, avatar must be an image data URL capped at
512 KB) and a 'saved' flag.
- Frontend usePersonalizationSync (mounted in the root layout when signed in)
hydrates the profile + theme stores from the server when a blob exists, and
otherwise migrates the existing local settings up once so nothing is lost;
later changes are written through, debounced. Writers keep using the local
stores unchanged.

* Studio: defer llama.cpp update probes and self-heal MLX on macOS
Two macOS startup problems shared one root area in the FastAPI lifespan:
- The llama.cpp capability + freshness probes ran inline before the server
yielded, so a cold/slow/flaky network on the GitHub freshness check blocked
'Application startup complete' (~34s on CI, longer in the field). Move both
probes to a daemon thread; app.state stays None until ready (status routes
already re-probe at request time). Opt out with UNSLOTH_DISABLE_UPDATE_CHECK=1.
- Train and Export were greyed out because mlx/mlx-lm/mlx-vlm arrive only
transitively and a resolver backtrack silently drops them, so CHAT_ONLY stayed
true. Add utils/mlx_repair.py: when Apple Silicon is detected without MLX,
reinstall mlx/mlx-lm/mlx-vlm by name on a daemon thread and re-run hardware
detection (opt out UNSLOTH_DISABLE_MLX_AUTOREPAIR=1). Surface a chat_only_reason
in /api/health plus a sidebar tooltip so a greyed Train/Export explains itself
instead of failing silently.
* Studio: guard model defaults against a None model name
load_model_defaults(None) called model_name.lower() with no guard, raising
'Error loading model defaults for None' before any model is selected. Return
an empty dict for a falsy/non-str name.
* Studio: drop obsolete upstream macOS + Windows Blackwell prebuilt pins
Both pins worked around gaps in ggml-org upstream prebuilts, but Studio now
routes every GPU host and all of macOS to the unslothai/llama.cpp fork
(published_repo_for_host), which ships the needed bundles, so both pins are
dead code on the default install path:
- macOS b9415: macOS always routes to the fork (its own macOS bundles), and
host_supports_macos_minos() is the backstop. The pin only fired under an
explicit --published-repo ggml-org override.
- Windows Blackwell b9360: Windows-NVIDIA routes to the fork, whose
windows-x64-cuda13 bundle covers Blackwell (manifest max_sm 120, toolkit
13.3), so the pin's self-disable check makes it dormant on every default
install; it could only activate under the same upstream override on a
13.0-13.2 driver.
Remove the pin constants, functions, and call sites. Keep the Blackwell
capability detection (_drop_blackwell_incapable_windows_cuda, _host_is_blackwell,
_windows_cuda_attempt_covers_blackwell) that still drops a non-sm_120 cuda-12.4
build on a Blackwell host. After this, an explicit --published-repo ggml-org
override on a Blackwell 13.0-13.2 host loses its GPU fallback and lands on CPU;
the default fork path is unaffected. Update the install selection-logic and
macOS-compat unit tests for the new no-pin behavior.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: walk back deeper on the macOS upstream prebuilt path
After removing the b9415 macOS pin, the explicit --published-repo ggml-org
upstream path still used the default 2-release fallback, so a pre-macOS-26 host
behind a run of macOS-26-only builds would exhaust two too-new plans (minos is
only checked post-download) and drop to a source build before reaching a
loadable older release. Walk back as deep as the fork macOS path
(DEFAULT_MAX_MACOS_RELEASE_FALLBACKS), turning the removed static pin into
dynamic discovery. Addresses review feedback on the macOS upstream fallback.
* Studio: pin transformers during MLX self-heal so it cannot break Studio
mlx-lm/mlx-vlm declare transformers>=5, but the single-env install pins
transformers==4.57.6. The self-heal used --upgrade with no constraint, so it
could upgrade transformers in the live venv and break the rest of Studio just to
make import mlx.core pass. Pin transformers to the installed version via a
constraint file: the resolver either finds an mlx build compatible with it or
fails (we stay chat-only), never upgrading transformers underneath Studio.
Addresses review feedback on the MLX repair install.
* Studio: harden MLX self-heal against an unsupported mlx-vlm
Pinning transformers alone made uv backtrack mlx-vlm to 0.3.9 (below unsloth-zoo's
mlx-vlm>=0.4.4), which imports but breaks VLM Train/Export -- so the self-heal
could clear chat-only onto a broken stack. Mirror the main installer: set
UV_OVERRIDE=overrides-darwin-arm64.txt so a current mlx-vlm coexists with the
transformers pin, require the same minimum versions unsloth-zoo declares, and
gate/validate on a full mlx_stack_available() check (not a bare import) so an
old or partial stack stays chat-only. Addresses PR review.
* Studio: filter Blackwell-incapable CUDA in resolve_upstream_asset_choice
resolve_upstream_asset_choice returned the first windows-cuda choice unfiltered,
so a Blackwell host could be handed an sm_120-incapable cuda-12.4 build while the
sibling planners drop it. Apply _drop_blackwell_incapable_windows_cuda here too
and fall through to the CPU bundle on a Blackwell host with no capable GPU asset.
Addresses PR review.
* Studio: re-poll health so MLX self-heal reaches an open UI
The sidebar cached the initial /api/health, so a successful background MLX
self-heal (chat_only flips false) did not re-enable Train/Export until a manual
reload. While chat-only for the recoverable mlx_unavailable reason, re-poll
/api/health and stop once Train/Export become available. Addresses PR review.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: make the disabled Train/Export tooltip reachable
The greyed Train/Export items pass a tooltip explaining why (e.g. MLX missing),
but a disabled <button> fires no pointer events and SidebarMenuButton only showed
tooltips while collapsed, so the explanation never appeared. Wrap a disabled
button in a focusable span and show its tooltip while expanded too; enabled items
keep the collapsed-only behavior. Addresses PR review.
* Studio: gate Train/Export on the full MLX stack, not bare mlx.core
detect_hardware enabled MLX training whenever `import mlx.core` worked, but the
MLX self-heal (utils/mlx_repair) treats a stack without mlx-lm/mlx-vlm at the
versions unsloth-zoo requires as inadequate. That asymmetry let the UI enable
Train/Export on exactly the partial/backtracked stack the self-heal is trying to
repair (greyed-in-but-broken VLM export). Gate on the same mlx_stack_available()
criterion so a partial stack stays chat-only (reason mlx_unavailable) and the
background repair restores it. Addresses PR review.

* Review fixes: isolate hardware-state test, robust transformers pin
- test_chat_only_reason.py: detect_hardware() assigns module globals directly,
which monkeypatch does not revert; the autouse fixture now saves and restores
DEVICE/CHAT_ONLY/CHAT_ONLY_REASON/IS_ROCM so a chat-only verdict here cannot
leak into other backend tests (e.g. test_utils.py) on a GPU host.
- mlx_repair.py: read the transformers version from importlib.metadata instead of
importing transformers, so the install pin is not silently dropped when
transformers has valid metadata but fails to import.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Fix CI: model full MLX stack in dispatch tests, keep selection test offline
dispatch (macOS) job:
- detect_hardware now gates MLX on the full stack (mlx_stack_available imports
mlx_lm/mlx_vlm and checks dist versions), so faking only mlx.core makes the
apple_silicon_mlx profile resolve to CPU. The dispatch tests assert the routing
decision when the stack IS usable, so model a complete stack:
test_hardware_dispatch_matrix patches utils.mlx_repair.mlx_stack_available and
test_is_mlx_dispatch_gate patches hardware._has_usable_mlx_stack. The stack
predicate's own internals stay covered by test_mlx_repair.py.
Repo tests (CPU) job:
- test_no_cuda_attempt_on_published_path_for_13_1 fell through to a live
github_release_assets() upstream fetch after the Blackwell filter dropped every
published attempt, which the offline security scanner blocks. Stub that fetch so
the walk-back deterministically finds no usable CUDA build and raises
PrebuiltFallback without network.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Harden MLX self-heal: prepare transformers constraint inside the try
attempt_mlx_repair runs on a daemon thread, but _transformers_constraint_args was
called before the try. A failure there (e.g. tempfile.mkstemp on a full disk or a
bad TMPDIR) would propagate unhandled and silently kill the self-heal thread.
Move the call inside the try and initialize constraint_path so any such failure
is caught and leaves Studio chat-only instead of crashing the thread.

* Use uppercase -GGUF suffix for GGUF export default names
Match the HF/Unsloth GGUF repo convention (Model-GGUF). Default export save dir
'<model>-gguf' -> '<model>-GGUF', the local-path sibling dir token '_gguf' -> '_GGUF',
and the model-name placeholder 'my-model-gguf' -> 'my-model-GGUF'. Pre-filled defaults
only; no backend/path logic change.
* Keep local GGUF sibling dir lowercase to match backend cleanup
The uppercase change to siblingGgufDirectory diverged from the backend's
hard-coded intermediate '<checkpoint>_gguf' dir (core/export/export.py), which
the export relocates GGUFs out of and then deletes. With the user's save dir
defaulting to '_GGUF', that no-longer-equal lowercase sibling would be relocated
and removed, which can delete an existing export. Revert the sibling default to
'_gguf'; the user-facing GGUF export name (buildRelativeSaveDirectory) keeps the
uppercase -GGUF token.
* Tighten GGUF sibling-dir comment
* Trim comments to be more succinct

* Show model provider/org in the trust_remote_code consent dialog
The consent dialog showed only the trailing model name (modelName.split('/').pop()),
dropping the owner. The HF org/owner is the 'who do I trust' signal the prompt is
asking about, so render it: 'NVIDIA-Nemotron-3-Nano-4B from "unsloth"'. A null
provider for local paths and bare names leaves those renders unchanged. Applies to
the enable/blocked/malware variants (shared description block).
* Only show consent provider tag for a confident single Hub repo
Tighten parseModelDisplay so the 'from "<provider>"' tag is shown only for a
canonical owner/repo Hub id (exactly one slash, both segments non-empty) that is
not a local path and not part of a multi-repo scan. This avoids misattributing a
relative local directory name (models/llama/7b) or a LoRA base/external repo's
finding to the wrong publisher in a trust decision. Extract a ProviderSuffix
component so both description branches render the clause identically via &&.
* Tighten consent provider-tag comments
* Source the consent provider tag from the backend
The dialog inferred the provider client-side from the model id, using
scanCreatedRepos (a cleanup-only list) to detect multi-repo scope and a
regex that missed bare relative paths like a local owner/model dir. Both
could attribute the scanned code to the wrong publisher.
Move the decision to the backend, where locality and scan scope are
known: _consent_provider returns the owner only for a single, non-local,
canonical owner/repo Hub id, and the route returns it as payload[provider].
The frontend now renders scan.provider directly.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Suppress consent provider tag when external auto_map code is scanned
A single Hub repo can declare an auto_map that loads code from another repo
(owner/other--module.Class). The scanner fingerprints that external repo's
Python, but security_targets still held only the primary, so the dialog
attributed the custom code to the primary publisher. Pass the external refs
collected during the scan to _consent_provider and return no provider when any
are present, so attribution is shown only for genuinely self-contained repos.
* Trim comments to be more succinct

* Scan auto_map for GGUF-only repo ids in the consent gate
The trust_remote_code consent gate treated any repo classified GGUF-only
(ships .gguf, no transformers-loadable weight) as having no remote code,
so _config_has_auto_map returned False even when a config declared an
auto_map and the repo shipped the referenced .py. The evaluator then
skipped the scan/fingerprint for that target entirely.
GGUF-inertness is a property of the loader, not the repo. A GGUF
selection loads via llama.cpp, which never reads config.json/auto_map,
and that case is already short-circuited upstream by the caller's
is_gguf check (the inference route skips the remote-code preflight for a
GGUF load). Every path that reaches this helper (export, training,
non-GGUF inference) loads through transformers/Unsloth from_pretrained,
which DOES import auto_map even for a repo that only ships .gguf weights:
the custom module runs before from_pretrained fails on the missing
transformers weights. The export path has no is_gguf guard and passes the
source straight to FastLanguageModel.from_pretrained(trust_remote_code=True),
so the in-helper GGUF skip let a repo with config.json (auto_map) +
modeling_x.py + only a .gguf run unreviewed code during export.
Drop the redundant repo-level GGUF short-circuit (and the now-unused
_is_gguf_repo helper). A direct .gguf file reference stays inert via
_is_direct_gguf_file_ref because that genuinely is a single-file llama.cpp
load; repo ids are always scanned. A GGUF repo whose auto_map ships no .py
still allows via the existing empty-code path, so legitimate GGUF loads
are unaffected (and GGUF inference never reaches this helper at all). Only
a repo that actually contains a .gguf can change behavior here; non-GGUF
repos (safetensors, MLX) are byte-identical before and after.
Update the GGUF auto_map test to expect a scan, and add two regression
tests: a GGUF-only repo shipping auto_map Python is scanned and blocked,
and a transformers-style repo (safetensors / MLX .npz) with auto_map stays
scanned and blocked.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Remove trust_remote_code config defaults; consent dialog is the only enabler
trust_remote_code is a per-load decision that must go through the remote-code
consent dialog, which scans the auto_map code and pins the exact version. Two
pre-set paths could still enable it without the user reviewing any code, and the
GGUF consent bypass rode one of them into the export flow:
- 4 model_defaults YAMLs shipped trust_remote_code: true (GLM-4.7-Flash,
Nemotron-3-Nano-30B-A3B, PaddleOCR-VL, ERNIE-4.5-VL).
- The frontend consent hook silently enabled trust_remote_code on a clean scan
whenever the caller flagged the model as needing it.
Remove every trust_remote_code key from the model_defaults YAMLs (the loaders
already default to False when the key is absent) and delete the frontend silent
auto-enable, so trust_remote_code is only turned on after the user approves the
scanned code in the dialog.
The three models that genuinely run custom code ship auto_map, which the consent
gate detects on its own via _config_has_auto_map, so the dialog still fires for
them in inference, training, and export (Nemotron is also re-granted by the
trusted-org auto-enable in the workers). GLM-4.7-Flash has no auto_map:
glm4_moe_lite is native in transformers 5.0+ and it loads with
trust_remote_code=False, so its YAML flag was a no-op.
Adds test_yaml_trust_remote_code_removed.py.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Drop YAML sections emptied by trust_remote_code removal
Removing trust_remote_code from a model YAML whose section had no other key
left a bare `inference:` header, which PyYAML parses as None;
load_inference_config() then does `model_config.get("inference", {}).get(...)`
and crashes on the None. Drop those now-empty section headers (24 model
defaults, all the `inference:` section) so callers fall back to family/default
inference params, which is the same result those models had before (their only
inference override was trust_remote_code).
Strengthens test_yaml_trust_remote_code_removed.py to forbid any empty/None
top-level section and to load the affected models' inference config end to end.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Add sweep asserting every model YAML loads via training + inference paths
Loads all model_defaults YAMLs through load_model_defaults (training) and
load_inference_config (inference) with the exact .get() access patterns the
routes use, so a malformed/None section that crashes either loader is caught.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Assert ex-TRC auto_map models still surface the consent dialog
Removing the trust_remote_code YAML default must not suppress the dialog for the
models that genuinely run custom code. The dialog is driven by the repo's auto_map
(via preflight_remote_code_consent_for_targets -> _config_has_auto_map), not the YAML
flag, so Nemotron/PaddleOCR-VL/ERNIE-4.5-VL still require consent; GLM-4.7-Flash (no
auto_map) takes no dialog and loads natively. Mocks only the Hub config + .py reader.

* Studio: self-heal unsloth namespace-package shadows in all subprocess workers
A directory named `unsloth` (or `unsloth_zoo`) without an __init__.py on
PYTHONPATH/sys.path, a stray source checkout or a polluted PYTHONPATH, makes
`import unsloth` resolve to an empty namespace package, so a worker's
`from unsloth import FastLanguageModel` dies with a cryptic
"cannot import name ... (unknown location)".
The LLM training path already recovered from this via `_ensure_real_packages`
in trainer.py (PR #6269), but the inference, export, and embedding-training
subprocesses imported Unsloth directly with no guard. Extract that helper into
a shared, dependency-free core/import_guards.py and call it before the Unsloth
import in every subprocess: it drops the offending sys.path entries, imports
the real packages (unsloth before unsloth_zoo so the pre-zoo GPU fixes run),
then restores sys.path. trainer.py now imports the shared helper instead of its
local copy.
Covers both unsloth and unsloth_zoo and both namespace origin forms (None and
"namespace"). The existing PR #6269 test now exercises the shared helper.
* Studio: distinguish a failed model load from no model in the attach gates
A failed load never sets the checkpoint, so the image and audio attach gates
fell through to "Load a model before adding images/audio", which reads as if
the user simply forgot to pick a model rather than that the load errored. Add a
dedicated lastModelLoadError to the chat runtime store, set only when an actual
load attempt fails (not on refresh, list, status, or unload errors, which keep
using modelsError) and cleared when the next load starts. The image gate (all
three call sites) and the audio gate now use it to report a failed load and
point at the server logs, while still blocking in exactly the same cases.
* Tighten namespace-shadow guard and load-error comments
