* Studio: Auto disables MTP for MLA models (GLM-5.2 et al.); UNSLOTH_MLA_MTP_ENABLED to re-enable
Studio's Auto speculative mode promotes any embedded-MTP model >=3B to
--spec-type draft-mtp. For MLA models (GLM-5.2/DeepSeek/Kimi) that is a
regression: llama.cpp's MLA/DSA MTP path keeps a duplicated full target-KV
context and recomputes the sparse-attention indexer every draft step, so it
runs ~2x slower than no speculation (GLM-5.2 UD-IQ1_S bench: 27 vs 45 tok/s,
flat across draft depth 1..6 and 96-100% acceptance, on both prose and code).
vLLM/SGLang get a speedup from the same model, so this is a llama.cpp
implementation gap, not a model property.
Auto now drops embedded MTP for MLA models and falls back to ngram-mod (or
spec-off when the binary lacks ngram-mod), mirroring the existing sub-3B
fallback. The metadata separator is kv_lora_rank: it is present on MLA models
and absent on non-MLA embedded-MTP models (Qwen3.x-MTP), whose MTP module is
structurally identical but fast, so a "full layer" heuristic cannot tell them
apart. Qwen MTP, separate drafters (Gemma, --model-draft), and non-MTP models
are unchanged.
Explicit overrides still engage the slower MTP route: choosing MTP / MTP+Ngram
in Settings, or passing --spec-type in extra args. UNSLOTH_MLA_MTP_ENABLED=1
re-enables Auto promotion for MLA once the upstream path is optimized.
A new spec_fallback_reason value "mla_mtp_disabled" surfaces this as an
Auto-mode policy downgrade (not a binary/update problem), with a settings
banner that points users at the MTP override. It is deliberately kept out of
the "Update llama.cpp" affordance since updating does not help.
Tests: resolver-matrix rows for MLA->ngram-mod / MLA-no-ngram->off /
non-MLA-Qwen->draft-mtp / MLA-separate-drafter->draft-mtp /
non-MTP-MLA->default / forced mtp|mtp+ngram on MLA->draft-mtp / env flag;
kv_lora_rank metadata fixtures; and reload-skip coverage (Auto ngram-mod is
idempotent, forced mtp bounces a reload).

* Fix clipped card shadows in Hub trending carousel
The carousel scroller only had vertical padding, so with overflow-x set
the first and last cards had their drop shadow clipped on the horizontal
edges. Add px-2 with a matching -mx-2 so the shadow has room while the
cards stay aligned with the section heading, and scroll-px-2 so snap-start
does not scroll the padding away on load.
* Align carousel edge fades with the scroll clip edge
The shadow fix gave the scroller an -mx-2 bleed, but the left/right fade
overlays stayed pinned to the wrapper edges, 8px inside the clip edge. That
left a thin strip where a card showed beside the fade, so the fade read as a
separate block instead of blending into the background. Offset both fades by
the same 8px so their opaque edge sits on the clip edge.
* Add click-and-drag panning to the Hub card carousel
The rows only scrolled by wheel or trackpad, and grabbing a card started
a native drag of its avatar image, so the cards could not be dragged to
move the row. Add mouse drag-to-scroll (touch and pen keep native
scrolling), swallow the click a drag would otherwise fire on a card, keep
plain clicks working, and block the avatar's native drag.
* Trim carousel edge fade width from 56px to 44px
* Smooth out carousel drag panning
Scroll snap was correcting the position on every drag frame, which made
the pan feel sticky. Disable snap while a drag is active and restore it on
release so the row follows the pointer and then settles on a card.
* Drop stale carousel drag when the button is released off-element
If a press ended outside the scroller before the drag threshold was
crossed, no pointerup reached us and the drag stayed armed, so a later
buttonless mousemove would scroll the row. Bail out and clear the drag
whenever the primary button is no longer held.
* Studio: fix Bypass Permissions menu freeze and show decimal GB for model sizes
Bypass Permissions freeze: the warning dialog lived inside the composer
"+"/More dropdown and kept the menu mounted via onSelect preventDefault,
so confirming or cancelling the dialog left both popovers frozen open.
Lift the dialog out of the menu into a store-driven
BypassPermissionsConfirmDialog mounted at a stable spot in the composer.
The menu item now closes normally on select and just toggles a new
bypassConfirmOpen store flag, so the popovers dismiss as expected.
Model search sizes: formatBytes divided bytes by 1024 but labelled the
result "GB", so unsloth/GLM-5.2-GGUF:UD-IQ1_S showed 201.8 GB where
Hugging Face reports 217 GB. Switch the search display to decimal
(base-1000) units to match what Hugging Face reports. The GPU-fit math
stays base-1024 since VRAM capacity is binary.
* Studio: address review feedback and add GLM-5.2 high/max/disabled thinking
Review feedback on the Bypass Permissions and size-format changes:
- Mount the Bypass Permissions warning dialog once at the chat-page root
instead of inside each Composer. It is driven by global store state, so
the per-composer mount meant Compare mode (multiple composers) rendered
duplicate dialogs and the shared-composer menu had none. A single root
mount fixes both.
- Defer opening the dialog past Radix's menu-close focus restoration with
setTimeout(0), so the dropdown does not steal focus back and break the
dialog's focus trap.
- Clamp the unit index in formatBytes so units[i] cannot go out of bounds
past TB (and to absorb log() float error at exact powers of 1000).
GLM-5.2 reasoning levels:
GLM-5.2's template gates thinking with enable_thinking and also reads a
reasoning_effort level ('high' or 'max'), so it needs high / max /
disabled rather than the binary toggle it got before (its style was
detected as enable_thinking, which made 'high' unreachable). Add a new
reasoning style 'enable_thinking_effort' that reuses the effort dropdown
but, unlike gpt-oss, can be fully disabled:
- detect_reasoning_flags classifies a template that has both
enable_thinking and reasoning_effort, extracting the discrete levels
from the quoted effort literals it branches on. Templates with only one
of the two (gpt-oss, Qwen3, DeepSeek, GLM-4.6) are unchanged.
- _request_reasoning_kwargs maps the new style to enable_thinking plus an
in-range reasoning_effort; disabling sends enable_thinking=false. The
gpt-oss reasoning_effort path is left untouched.
- The backend reports reasoning_effort_levels on the load/status response;
the frontend carries them through to the effort dropdown and sends
enable_thinking + reasoning_effort for this style.
Verified: backend reasoning kwargs render the real GLM-5.2 template to
"Reasoning Effort: High/Max" (thinking) and an empty <think></think>
(disabled); tsc, eslint, i18n parity and the production build all pass.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: address review feedback on reasoning effort and formatBytes
- chat-adapter localReasoningEffort: accept 'minimal' so a template that
branches on it (extracted into reasoning_effort_levels) is sent through
instead of being coerced to 'low' and then dropped by the backend.
- formatBytes: return '0 B' for non-finite / non-positive sizes (missing
metadata -> NaN, Infinity, negatives) and clamp the unit index lower
bound to 0, so sub-1-byte values can't produce a negative index.
* Studio: hybrid reasoning none gate and decimal GB in load progress
- _request_reasoning_kwargs: for enable_thinking_effort models, treat a
raw reasoning_effort='none' (OpenAI 'no reasoning' sentinel) as the
enable_thinking=false off gate, so a direct API caller can disable
thinking even without passing enable_thinking. The frontend already
sends enable_thinking=false; this only affects raw API callers.
- use-chat-model-runtime: the download / 'X of Y GB in memory' load
progress divided bytes by 1024**3 but labelled GB, so it disagreed with
the model picker and Hugging Face. Use decimal GB (1e9) to match.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: carry hybrid reasoning levels on all load paths and harden formatBytes
Review follow-ups on the enable_thinking_effort work:
- Every model-load path now copies reasoning_effort_levels and derives
supportsReasoningOff, via a shared reasoningCapsFromLoad() helper. The
shared/Compare composer load and the three chat-adapter auto-load paths
previously set only reasoningStyle, so a GLM-style hybrid model loaded
through Compare or first-chat auto-load fell back to the default
low|medium|high and lost its Max / Off controls.
- The local send path clamps the effort to the loaded model's advertised
levels (clampReasoningEffortToLevels) instead of a hard-coded list. A
stale "max" carried over from an external provider no longer reaches a
pure reasoning_effort (gpt-oss) model that only accepts none|low|medium|
high, where the backend would have dropped it.
- formatBytes divides iteratively instead of via Math.log, which has float
error at exact powers of 1000 (log(1e12)/log(1000) = 3.9999... would
label 1 TB as "1000 GB"). Keeps the non-finite/non-positive guard.

* Studio: free chat model VRAM at training start only when the GPU is tight
The training start route unconditionally tore down the transformers/MLX
inference subprocess before training, and never stopped the llama.cpp GGUF
server at all, so a loaded GGUF chat model kept holding VRAM for the whole
run. Conversely the HF model was always unloaded even when there was plenty
of room to keep it.
Make the unload VRAM aware and cover every inference backend:
- Add routes/training_vram.py with summarize_resident_chat(),
can_keep_chat_during_training() and free_chat_models_for_training(). The
keep/unload decision reuses the same estimator and live per device free
VRAM reader the training GPU selection already uses (auto_select_gpu_ids,
estimate_required_model_memory_gb, get_visible_gpu_utilization), so the
probe agrees with the placement computed later in start_training.
- When a chat model is resident and training fits alongside it with a
conservative margin (required_gb * 1.15 + 4 GB), keep it loaded so the
user can train and chat at the same time; on a multi GPU box training
lands on a different GPU and both coexist. Otherwise unload the HF/MLX
orchestrator and the llama.cpp GGUF server before training starts.
- The export subprocess shutdown stays unconditional and now runs first so
its freed VRAM is reflected in the decision.
Default deny: non CUDA backends, unestimable models, or any probe error
fall back to the previous always unload behavior.
Adds tests/test_training_vram_coexistence.py and updates two existing route
tests in test_gpu_selection.py.

* Studio: per-GPU floor for explicit GPU lists + don't unload chat on invalid gpu_ids
Address review feedback on the chat coexistence probe:
- Explicit gpu_ids mode now enforces a per-GPU floor in addition to the
aggregate free-VRAM check, mirroring auto_select_gpu_ids' min_per_gpu_N.
Without it, an uneven split such as free [45, 10] for a 40 GB job passed
the aggregate threshold and kept chat loaded even though the 10 GB GPU
could not hold its training shard, risking an OOM.
- Invalid explicit gpu_ids (ids outside the visible set, or a UUID/MIG
mask) make resolve_requested_gpu_ids raise. That request is rejected with
a 400 before training starts, so leave the resident chat model untouched
instead of unloading it.
- Tighten the target_modules / gpu_ids type hints to List[str] / List[int].
Adds tests for the per-GPU floor (uneven split unloads, even split keeps)
and for invalid gpu_ids keeping the chat model loaded.

* Studio: only free chat VRAM once training will start; handle in-flight and CPU-only chat
Address the second review pass on the chat-coexistence path:
- Run the chat/export VRAM teardown as a before_spawn hook inside
TrainingBackend.start_training, fired only after the start guards pass.
Previously the route freed chat VRAM before calling start_training, so a
refused start (e.g. a lingering pump thread) would tear down the resident
chat model even though no training job began.
- Treat an in-flight HF chat load (loading_models set, no active model yet)
as not safely sizeable: free it rather than risk both OOMing as the load
keeps allocating after training starts.
- Do not count or tear down a GGUF llama-server confirmed to run entirely on
CPU (_gpu_offload_active is False): it holds no VRAM, so killing it cannot
help training fit.
Adds tests for the before_spawn hook (runs on start, skipped when a
subprocess is alive or a pump thread will not die, survives a hook error),
the in-flight load flag, and the CPU-only GGUF exclusion in both the resident
summary and the unload path.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: treat any in-flight chat load (HF swap / mid-start GGUF) as unsafe to keep
Tighten the in-flight detection in summarize_resident_chat so the keep check
never sizes a load that is still allocating:
- Flag loading on ANY non-empty loading_models, not only when active_model_name
is empty. load_model adds the new model to loading_models before clearing the
old active_model_name, so a replacement load during a swap was previously
sized as a normal resident and could OOM as the new model finishes loading.
- Flag a GGUF server that is active but not yet healthy (is_loaded False) as
in-flight: it is still mmaping/offloading layers, so its final VRAM footprint
is unknown.
Consolidates the signal into a single resident["loading"] flag; the route frees
the chat model whenever it is set. Adds tests for the replacement HF load and
the mid-start GGUF cases.

* Studio: tighten comments in chat/training VRAM coexistence (comments only)
* Studio: run before_spawn VRAM hook only after GPU-selection validation
Reviewers found the before_spawn hook fired before prepare_gpu_selection
validated gpu_ids (and before config build), so a refused start (invalid
gpu_ids -> 400, or a bad grad-clip value) could still tear down chat/export
VRAM. Move the hook to immediately before proc.start(), once all synchronous
validation and process construction have passed. This also fixes the route's
in-flight-chat loading branch, since that teardown runs inside the same hook.
Add test_hook_skipped_when_gpu_selection_rejects.
* Studio: recompute GPU auto-selection after the before_spawn VRAM hook
Codex P2: with before_spawn moved after prepare_gpu_selection, placement was
frozen against the pre-teardown VRAM state while the hook freed export/chat
afterward. Auto-selection could pin training onto a GPU the hook then cleared
(or onto a kept chat model). Split validation from placement: explicit gpu_ids
are still validated before the hook (raise -> 400, no teardown; explicit
placement is VRAM-independent), but VRAM-dependent auto-selection now runs
after the hook so it sees the freed memory.
Add test_auto_placement_runs_after_hook and test_explicit_placement_validated_before_hook.
* Studio: allow chatting during training (lift sidebar gate + VRAM-aware load guard) (#6335)
* Studio: allow chatting during training (lift sidebar gate + VRAM-aware load guard)
The sidebar disabled New Chat, project, and home navigation while a training
run was active, so users could not chat during training even though the backend
serves inference fine alongside a run. This removes that gate and adds a backend
guard so the one genuinely risky operation, loading a new local chat model
mid-training, is refused with a clear 409 when it would not fit beside the run.
Frontend (app-sidebar.tsx): drop the chatDisabled = isTrainingRunning gate and
its consumers. Navigation triggers no model load on its own, so chat stays
usable during training.
Backend (routes/training_vram.py, routes/inference.py): add
can_load_chat_during_training plus a load/validate guard that sizes the same
effective load the loader performs (LoRA 4-bit to 16-bit resolved first, HF auto
placement via auto_select_gpu_ids, explicit multi-GPU per-GPU floor, GGUF sized
from on-disk shards and companions or the selected remote variant). It is a
no-op when training is inactive, never blocks external providers or
already-resident models, and default-denies only on a CUDA sizing failure so a
load can never OOM the run. Validate refuses early with the real settings so the
frontend does not unload the resident chat model for a load that would be
rejected.

* Studio: address review feedback for chat-during-training load guard
- Run the load/validate VRAM guard via asyncio.to_thread so the sync
nvidia-smi + HF metadata work never blocks the event loop.
- Size the GGUF KV cache at the requested context (_estimate_gguf_kv_gb)
and add it to the local GGUF estimate so large-context picks are not
under-counted.
- Keep the requested quantization when adapter_config.json is malformed
(not a JSON object) instead of raising in _effective_load_in_4bit.

* Studio: size the training load guard at the launcher's effective GGUF context
The GGUF KV-cache estimate used max_seq_length only, but the llama.cpp
launcher honors a user --ctx-size/-c in llama_extra_args. A load such as
max_seq_length=4096 with --ctx-size 131072 was sized against a 4k cache
while the server allocates 131k, so the guard could approve a long-context
GGUF load that then OOMs training. Size the guard's KV at the larger of
max_seq_length and the parsed --ctx-size (reusing the launcher's own
parse_ctx_override), keeping the conservative f16 cache so the estimate is
never smaller than what the server allocates.
The chat model picker also validated with the raw max_seq_length while
/load sizes with resolveLoadMaxSeqLength, so validate could pass, unload
the current model, then have /load reject the native-context load. Validate
now uses the same effective context; the load path is unchanged.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: size the GGUF training guard at the server parallel-slot count
The KV-cache estimate assumed a single slot, but llama-server allocates the
cache across --parallel slots (app.state.llama_parallel_slots). On a Studio
launched with --parallel N>1 the guard under-sized the cache N-fold and could
approve a GGUF chat load that then OOMs training. Thread the same slot count
the loader uses into the guard's KV estimate; default 1 leaves single-slot
setups unchanged.

* Trim comments for chat-during-training guard
* Studio: keep chat generation alive across navigation; Train spinner + Return to Chat
Hoist the base chat runtime above the routed outlet so navigating to Train (or any tab) no longer aborts an in-flight generation; only an explicit Stop cancels. Add a Train sidebar spinner and swap New Chat to Return to Chat while a run is active, with a lightweight completion watch so the spinner clears from any tab. Also respawn a chat llama-server killed mid-session and guard unreadable HF cache dirs that 500'd the hub model list.
* Studio: show Return to Chat on the Train tab whenever a chat is live
Previously the top sidebar item only swapped to Return to Chat while training was running; on the Train tab with an idle/just-finished run it stayed New Chat, which started a fresh thread and cancelled an in-flight generation. Show Return to Chat (and navigate back, preserving the run) whenever a generation is running or its thread is still active, or training is in progress.
* Studio: keep a running chat alive when starting a New Chat
Starting a New Chat (or switching threads) while a generation was in flight
remounted the single-chat runtime provider, which detached the in-flight run
and cut the previous chat off (it showed up frozen / empty when reopened).
Key the single-chat view by project instead of by thread or new-chat nonce so
the provider stays mounted and assistant-ui switches to a fresh thread in place.
The previous generation keeps streaming in the background and autosaves on
completion, and returning to that thread reattaches the live run instead of
reloading a half-saved one.
Also:
- "Return to Chat" now lands on the thread that is still generating rather than
the empty new chat that became active after New Chat.
- Skip the explicit /inference/cancel POST when an abort comes from a runtime
detach (navigation / background switch) rather than an explicit Stop, so a
backgrounded generation is never cancelled behind the scenes.
* Studio: make model export non-blocking and inline
The Export tab opened a full-screen modal that trapped focus, could not be
closed or cancelled while running, and showed no progress. It also stopped
training and unloaded the chat model before loading, so export could not run
alongside them.
Export now mirrors the training runtime pattern:
- Inline panel embedded where the Export Model button was, with no modal or
backdrop, so the rest of the UI stays usable during an export.
- Global export runtime store plus an app-root lifecycle hook, so a run keeps
going and streaming across navigation and is reflected on the Export nav item
from any tab.
- The worker log stream now stays connected across the load to export phase
boundary instead of stranding on "Waiting for worker output".
- Progress bar driven by phase and quant index (quant N of M for GGUF), with
elapsed time and a working Cancel.
- load-checkpoint no longer stops training or unloads inference; export loads in
its own subprocess in parallel and surfaces out-of-memory as a clear error.
- Add POST /api/export/cancel and is_export_active on /api/export/status.
* Studio: show Return to Chat on the Export tab too
Extend the New Chat to Return to Chat swap to the Export route so leaving a
running chat for Export offers a way back to the live generation, matching the
Train tab.
* Studio: smooth out Export animations and polish the panel
- Drop the height-based reveal animations (source switch, run panel, quant
picker, hub fields) that caused flashing and reflow; use instant swaps and
quick opacity fades instead.
- Method and quant cards now transition colors only, with no transition-all or
hover lift, so selecting a method or quant is crisp instead of jumpy.
- Auto-scroll the export panel into view when it opens and add a scroll-to-bottom
button when its output is below the fold, like Chat.
- Show Return to Chat on the Export tab while an export is running, matching how
training drives it on the Train tab.
- Surface the current phase or stage in the live output before the first worker
line arrives so the panel never looks stuck while progress is advancing.
* Studio: show Return to Chat on every non-chat tab
Generalize the Return to Chat swap from just Train/Export to any non-chat route
(Recipes, Projects, Hub, ...) so a running or active chat is always one click
away, instead of showing New Chat there.
* Studio: stream export logs over the Cloudflare tunnel; drop janky export animations
Exporting over a --secure Cloudflare quick tunnel showed "connecting..." with no
logs while the progress bar advanced. Cloudflare buffers text/event-stream and
only flushes when the stream closes, so the SSE log stream never reached the
browser during the run (direct localhost is unaffected, which is why this only
showed up over the tunnel).
Add a tunnel-safe JSON poll fallback (GET /api/export/logs?since=) that the
runtime lifecycle hook polls while a run is active. Short JSON responses are not
buffered by the proxy, so logs show up in near real time over the tunnel. It
shares the orchestrator's monotonic seq cursor with the SSE stream and the store
de-dupes by seq, so the two transports run together (SSE on localhost, poll over
the tunnel) without double-printing. A successful poll marks the panel
"streaming" instead of leaving it stuck on "connecting...".
Also remove the framer-motion AnimatePresence reveals from the export config and
run panel (quant picker, hub fields, the inline run panel, and the live log
section). The expand/slide animations flashed and felt clunky; the sections now
render in place.
* Studio: recover export over the Cloudflare tunnel when the blocking POST times out (524)
A model export over a --secure Cloudflare quick tunnel showed "Request failed
(524)" even though the export succeeded on the backend (the GGUF was written).
Cloudflare returns 524 when a single request takes longer than ~100s to respond,
and a GGUF conversion routinely runs for minutes, so the blocking per-method
export POST is cut off while the backend keeps going.
Confirm completion via short status polls instead of relying on the long POST
response (the same approach that fixed log streaming):
- The orchestrator records each finished op's outcome (status / output_path /
error) with a monotonic seq, exposed on GET /api/export/status.
- parseJson now preserves the HTTP status; a 524/520/522/523/502/503 or a
status-less network drop is classified as a recoverable transport error.
- runExport wraps each phase (load, every export method, each GGUF quant): on a
recoverable failure it keeps the run alive (logs keep streaming, the panel
shows "reconnecting...") and polls status until the still-running op finishes,
then settles from the recorded result, recovering the output path for the
success banner. A real 4xx still fails immediately; localhost still uses the
fast POST response. applyBackendStatus also settles a reloaded run from the
last-op record.
Verified over the tunnel: a 3m14s gemma-4-E4B-it GGUF export now ends on the
success banner with the output path instead of 524.

for more information, see https://pre-commit.ci
* Studio: keep the export method + logs visible after navigating away mid-export
While an export was running, navigating to another tab and back to Export
remounted the page and reset the local form state (exportMethod, quant levels),
so the method card showed unselected and the run panel's log area was hidden
until the card was re-clicked. The run itself lives in the global store and was
unaffected.
Seed exportMethod / quantLevels from the active run's summary via lazy useState
initializers on (re)mount, and gate the panel's log area on the live run
(isExporting / logLines / the run's method) rather than only the local form
selection. The card stays selected and the logs/progress stay visible across
navigation; nothing changes when no run is active.

* Studio: address export/training review findings
- Export: guard Start against an empty GGUF quant selection so an inline-panel
run with no quant can't settle as success with no file produced.
- Export: thread the source HF token into the background load so gated/private
HF source exports (and gated bases) authenticate, matching the consent path.
- Export: only settle a recovered (non-owned) run as a finished export when the
last backend op was an export, not a standalone load_checkpoint.
- Training: free the export subprocess whenever an export is active, not only
once a checkpoint is loaded, so an in-flight export load can't race training
for VRAM (current_checkpoint is unset during the load phase).

Switch the sidebar profile button from rounded-full to rounded-[5px] so its hover background is a rounded rectangle instead of a pill. The collapsed icon-only state stays circular. Styling only.
* Studio: scale export GGUF size estimates from the real model size
The Export page showed hardcoded, model-independent GGUF quant size
labels (Q8_0 ~8.2 GB, BF16 ~14.2 GB, ...) calibrated for an ~8B model.
For a 35B MoE model like Qwen3.6-35B-A3B (67 GiB bf16, Q8 ~34 GiB) the
picker wrongly reported Q8 ~8.2 GB. Only the displayed estimate was
wrong; the actual export via save_pretrained_gguf was always correct.
Add GET /api/models/export-size, which returns a model's MoE-aware
fp16/bf16-equivalent size and total params using the existing
estimate_fp16_model_size_bytes (safetensors -> config -> local -> vllm).
The result is memoized and degrades to nulls so a size hint can never
break the Export page.
The Export picker now scales each quant from that size
(bytes ~= fp16_bytes * bits_per_weight / 16, GiB units to match the
model selector), and renders no size when it is unknown rather than a
misleading fixed number. The Est. size summary in the page and dialog
is restored now that the value comes from the backend.

* Studio export-size: address review feedback
- Run the size estimate off the event loop with asyncio.to_thread so a slow
Hugging Face request cannot stall other API or SSE endpoints.
- Cache only successful estimates; a transient failure (offline, gated before
credentials) is no longer pinned as unavailable until restart.
- Forward the HF token so private and gated models can be sized, and refetch
when the token changes.
- Clamp the size formatter index so sub-1-byte values cannot pick an
out-of-range unit.
* Studio export-size: address second review pass
- Send the HF token in an X-HF-Token header instead of the query string, so
it never lands in URLs, logs, or browser history.
- Key the estimate cache by model id only (the fp16 size is token independent),
so HF tokens are never retained in the cache.
- Restrict local-path sizing to known Studio roots (outputs/exports/cache/home)
so an authenticated caller cannot trigger a scan of an arbitrary directory.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio export-size: fix CI (import-hoist + isolated-load test stubs)
- Import ExportSizeResponse from models.models in routes/models.py instead of
re-exporting it through models/__init__.py, so the import-hoist lint does not
flag a newly added but un-loaded re-export (models/__init__.py is unchanged).
- Add Header and ExportSizeResponse to the stubbed fastapi / models.models in
test_export_absolute_paths.py, which loads routes/models.py in isolation.
* Studio: validate export-size local path before filesystem access
CodeQL flagged the export-size local-path guard as path injection: the
user-provided model path was resolved and stat-ed before it was checked
for containment under a Studio data root. Decide containment by lexical
normalization (normpath/abspath/expanduser, no filesystem access) and
only touch the filesystem once the path is proven to sit under a trusted
root, so an unvalidated value never reaches a filesystem call. Add a
direct containment unit test (under-root, root itself, missing, /etc,
and '..' traversal).
* Studio: trim export-size comments to be more concise
Shorten docstrings and comments on the export-size endpoint, helpers, tests,
and frontend size utilities; drop comments that just restate the code. Verified
code-identical (comments only) via AST/TS-compiler check. No behavior change.
* Studio: harden export-size local-path handling
Address review feedback on the export-size endpoint's local sizing:
- Resolve symlinks and re-verify containment in _is_sizable_local_path so a
symlink inside a Studio root can't point the sizer outside it.
- Re-validate the resolved LoRA base before sizing, so a crafted adapter
whose base_model points outside the roots can't redirect the scan.
- Skip nested checkpoint-*/global_step* snapshots when summing local weight
sizes so a run dir's intermediate checkpoints don't inflate the estimate.
- Size the checkpoint directory for full fine-tune checkpoint exports (whose
base may be a local/custom path), keeping base-model sizing for adapters.
Adds tests for the adapter-base escape, symlink escape, and nested-checkpoint
exclusion.

* Harden model fetching: consent gate for trust_remote_code
Add a load-path consent gate that scans a model's auto_map repository code
before it executes and blocks CRITICAL/HIGH findings unless the user pins
approval of that exact code version. Capability detection stays code-free,
reading raw config.json instead of AutoConfig.
- Scan config.json and tokenizer_config.json auto_map, nested local helpers,
and external owner/name--module repos; fail closed on partial downloads.
- Gate inference, training, and export workers, including the MLX path and a
LoRA's base model, and report requires_trust_remote_code from the raw config
so chat and auto-load surface the dialog.
- Verify trusted-org auto-enable against the Hub with the request token and key
the verdict cache by token; reject local-path and spoofed names.
- Add a consent dialog showing the flagged file, line, and surrounding code.
- Thread hf_token through the scan and load paths for gated repos.
* Address review: token handling, tokenizer/LoRA scan coverage, rollback
- Send the HF token for remote-code scans in the POST body, not the URL, so it
never lands in a log or browser history.
- Collect tokenizer_config.json auto_map files directly instead of relying only
on the repo file listing.
- Resolve a LoRA's base model for the validate flag and the scan endpoint so the
dialog scans the code the workers actually gate.
- Pass the request token to the training YAML trusted-org auto-enable.
- Resend a previously approved fingerprint when rolling back to a custom-code
model after a failed switch.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Consent UX: drop legacy chat toggle, fix decline copy, purge declined downloads
The per-model consent dialog is now the single approval path for custom
(auto_map) code in chat, so three leftovers from before it existed are removed:
- Remove the "Enable custom code" switch from Chat Settings and stop persisting
trust_remote_code, so a previously saved blanket-on cannot linger and load a
model without going through per-version review. The flag stays as an internal
YAML/preset default (e.g. first-party auto-enable); the load path still gates
every custom-code load on a fingerprint only the dialog produces.
- Reword the decline message and the auto-load toast to describe approving the
model's code from the dialog, not a missing settings toggle.
- On decline, purge the repo the scan downloaded so untrusted code is not left
on disk. A new /api/models/discard-remote-code endpoint deletes only a
metadata-only cache entry the scan created; it refuses local paths, loaded
models, and any repo with weight files cached, so a model the user already had
or pre-downloaded is always left untouched. The frontend only calls it when
the scan reported created_by_scan.
Adds discard-endpoint tests (delete metadata-only, refuse on weights/gguf,
refuse local, no-op when not cached) and a created_by_scan payload assertion.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Export: remove the user-facing trust remote code toggle
The Export page kept a "Trust remote code" switch (default on) next to the HF
token field. Like chat, custom (auto_map) code should be approved per model
through the load-time review dialog, not a persistent blanket switch, so the
toggle is removed. The export load path already routes through the same consent
dialog: an HF source now starts with trust_remote_code off and only enables it
when the user approves the scanned code in the dialog (a local checkpoint the
user exported stays trusted by default). With the dialog unreachable and no
approval, an HF source loads with trust_remote_code off, which fails closed
rather than running unreviewed code.
* Block loads of repos with unsafe files using Hugging Face's security scan
The trust_remote_code consent gate covers one load-time RCE vector (a repo's
auto_map Python). It does not cover the other: a malicious pickle inside a weight
file (pytorch_model.bin, *.pkl, *.dat) deserializes during from_pretrained even
with trust_remote_code False, so a repo with a normal config plus a poisoned
pickle slips past the existing gate.
Add a metadata-only malware gate that uses Hugging Face's own scan (picklescan +
ClamAV), read via model_info(securityStatus=True).security_repo_status. It never
downloads, opens, or unpickles the flagged files; it only reads the Hub's verdict
and surfaces the flagged file names. New evaluate_file_security runs
unconditionally (independent of trust_remote_code) in every load path (inference,
training SFT/MLX, export), blocking the load when a file is flagged
unsafe/suspicious/malicious. The /remote-code-scan preflight and the validate
endpoint also report the result so the consent dialog opens as a hard block (no
override) listing the flagged files, even for a repo with no custom code.
Policy: hard block with no user override; fail open when the scan is unavailable
(offline/unscanned) so legitimate loads are not broken; no first-party exemption
(a poisoned pickle in a compromised trusted repo still blocks); local paths and
GGUF are skipped (no Hub scan, non-pickle format). Blocking does not gate on
scansDone, since that is often false for clean repos and a file already flagged
unsafe is unsafe regardless.
Adds test_file_security.py covering the block/allow/fail-open/skip matrix.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Address review: scan list-form tokenizer auto_map, gate unsafe files on all load paths
Fixes from a 10-reviewer pass on the model-fetching hardening:
- The remote-code scanner skipped tokenizer auto_map encoded as a [slow, fast]
list (transformers' standard tokenizer shape, e.g.
{"AutoTokenizer": ["owner/repo--tokenization_x.Slow", null]}). External
tokenizer code in that form was never fetched, scanned, or fingerprinted, so an
AutoTokenizer(trust_remote_code=True) load could run it. _auto_map_refs now
flattens string, list, and nested values. Adds a regression test.
- Compare-mode chat loads and background auto-load only gated on
requires_trust_remote_code, so a repo flagged unsafe by the Hub scan but with no
custom code skipped the hard-block dialog. Both now also gate on
requires_security_review, matching the main chat path.
- The /remote-code-scan and /validate routes collapsed a LoRA adapter to its base
before the malware scan, so unsafe files in the adapter repo itself were missed
in the pre-load review (the workers already scan both). Both routes now run the
file-security scan over the adapter and the base.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Require approval for all HIGH remote code, fail closed when unscannable
Tighten the load-time security gates based on review:
Consent gate
- HIGH-severity auto_map code now requires explicit, per-version approval for
every repo, including first-party unsloth/nvidia. The org is no longer a
blanket bypass: a compromised first-party repo with HIGH code still warrants
review. CRITICAL stays a hard block; clean code still loads after the consent
prompt.
- Fail closed when auto_map code is present but cannot be fully fetched or
listed to scan (gated, offline, transient, or a repo-listing failure that
could hide an imported helper). We cannot fingerprint code we cannot see, so
this is a non-approvable block, retryable once the repo is reachable.
- Scan auto_map from every config that can carry one (model, tokenizer, image
and feature processor, processor, video processor), not just config.json and
tokenizer_config.json, so a custom-processor model is not missed. The file
list is the single source of truth in remote_code_scan and is pinned to the
transformers filename constants by a guard test.
- Distinguish a genuine 404 (config truly absent) from a transient error: only
the latter forces a scan, so a repo with no config is correctly a no-op.
Malware gate
- Scan a remote repo even when its name ends in .gguf; only local paths skip the
Hub scan, so a repo cannot dodge the scan by naming itself "*.gguf".
- Correct the docstring: a file already flagged unsafe blocks regardless of
scansDone; the only fail-open path is an unavailable scan.
Coverage
- Resolve a remote LoRA adapter's base model (not just local directories) so the
base, where the code and weights actually execute, is scanned in validate,
the scan route, and the training and export workers.
- Gate the embedding training path (FastSentenceTransformer) with the malware
and consent checks, matching the other load paths.
Tests updated and added for each change.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Scope malware gate to the load-path vector; stop false-blocking first-party models
Follow-up hardening from a second review pass + a broad live model matrix
(unsloth/* , nvidia/* , third-party, and the eicar malware repo).
Malware / unsafe-file gate
- Scope the block to the actual RCE vector: a root-level file in a code-executing
format. from_pretrained deserializes weight files at the repo ROOT, so a flag is
only a load-path pickle vector there. Two exclusions, because neither is loaded:
inert formats (safetensors is tensor-only, gguf is non-pickle, configs/text/
images) and files in subdirectories. This keeps eicar blocked (its *.pkl/*.dat/
eicar_test_file sit at the repo root) while no longer false-blocking legitimate
first-party repos: nvidia/Nemotron-H-8B-Base-8K ships root safetensors plus NeMo
pickle checkpoints under nemo/ that the loader never touches, and the Hub flags
both; the gate previously hard-blocked it.
- Unknown / future non-"safe" levels now fail closed (block) instead of being
silently allowed, so Hub schema drift cannot introduce a bypass; in-progress
("pending"/"scanning"/"error") levels stay non-blocking to avoid false blocks.
Consent gate
- Ignore a STALE own-repo auto_map target that is absent from the repo listing (an
older config pointing at a file the repo no longer ships) instead of failing the
whole repo closed as unscannable. The present .py are still fully scanned, which
is the stronger coverage, and a file that is not there cannot execute. This
unblocks first-party models like unsloth/PaddleOCR-VL (its tokenizer_config.json
names processing_ppocrvl.py while the repo ships processing_paddleocr_vl.py). A
referenced .py that IS present but cannot be fetched, and a repo-listing failure,
still fail closed.
Remote LoRA base resolution
- Distinguish a genuine 404 (not a LoRA / repo absent -> None) from a transient
error: the transient case is retried once, then logged as a WARNING (a missed
base is scanned by neither gate) rather than silently skipped.
Discard endpoint
- Treat .onnx and .ckpt as weights so a repo whose only heavy artifact is one of
those is never eligible for the declined-download purge.
Tests added for each: load-path scoping (safetensors/subdir/Nemotron-H shapes,
unknown-level fail-closed, pending non-block), stale own-repo auto_map ref, remote
LoRA transient retry, and the empty-config-list (all-404 -> []) semantics.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Make LoRA-base transient-warning test robust to logging backend
Assert on the logger object directly instead of capsys, so the test does not
depend on whether the real structlog logger or the module-stub logger is active
(which varies with test collection order).
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Allow a repo with auto_map but no executable code (e.g. GGUF) instead of blocking
A config can declare an auto_map yet the repo ship NO executable .py -- most
commonly a GGUF repo whose config.json carries an auto_map copied from the original
model (e.g. unsloth/Llama-3_1-Nemotron-Ultra-253B-v1-GGUF references
modeling_decilm.py, which the GGUF-only repo does not contain). A GGUF model loads
through llama.cpp, which never executes auto_map, and transformers cannot run a file
that is not present, so there is nothing to scan and trust_remote_code is a no-op.
The fail-closed change treated this empty result the same as "code is present but we
could not fetch it" and hard-blocked the load. Distinguish the two: repo_remote_code_files
now RAISES RemoteCodeUnscannable when code is present but cannot be fully fetched or
listed (offline / gated / transient / a present .py that 404s / a listing failure),
and returns an empty dict only when the listing succeeded and the repo genuinely ships
no executable .py. The consent gate blocks on the exception (fail closed) and allows the
empty case as a no-op. Real unscannable code still hard-blocks; eicar and CRITICAL/HIGH
custom code are unaffected.
Verified against all 37 unsloth/*Nemotron* models (two GGUF repos were false-blocked,
now load) and the existing matrix (eicar still blocks; DeepSeek-OCR / NVLM-D-72B still
prompt approvable consent). Tests updated to expect the raise for unscannable cases and
added for the no-executable-code no-op.
* Ignore vestigial auto_map in GGUF repos (llama.cpp never runs it)
A GGUF repo's config.json is often copied verbatim from the original
transformers model, auto_map and all, but a GGUF load goes through
llama.cpp which never executes auto_map, so the config is inert. Treat
a direct .gguf reference, and a repo that ships .gguf weights with no
.safetensors, as having no remote code so the consent flow is never
triggered. A mixed repo with both .gguf and .safetensors is still gated,
since the safetensors variant would load through transformers where
auto_map does run. The check sits behind the existing auto_map-present
gate so normal models pay no extra repo listing.
* Add scanner-result copy to the remote-code consent dialog
Make the consent dialog state the scan outcome in plain language for
every model. When the static scan finds nothing, reassure the user with
'Our automatic scanner did not flag any worrying files, but please
double check.' (shown only for the clean, approvable case). When the
scan flags custom code or unsafe files, label the list with 'Our
automatic scanner flagged issues including:'. The Hugging Face
attribution for unsafe files stays in the dialog description.
* Close GGUF-suffix consent bypass for repo ids ending in .gguf
The .gguf short-circuit in _config_has_auto_map skipped the scan for any
model name ending in .gguf, including a bare two-segment repo id like
'evil/model.gguf'. Such a repo can still ship safetensors plus auto_map
Python that transformers would execute, so skipping the scan was an
asymmetric bypass (file_security already scans those repos). Restrict the
short-circuit to genuine direct GGUF file references via
_is_direct_gguf_file_ref: a local .gguf path, or a remote repo_id plus
filename (three or more segments). A two-segment repo id named *.gguf now
falls through to the config scan and _is_gguf_repo file inspection, so it
only skips consent when it actually ships .gguf weights and no safetensors.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Align consent dialog body with the title and fix narrow-width overflow
The scan results (the 'Our automatic scanner...' label, finding/unsafe
cards, and the clean-scan reassurance) sat at the dialog's left padding
while the title and description were indented past the status icon, so
the body did not line up under the description. Move the title,
description and results into one column to the right of the icon so they
share a left edge, and let that column fill its width so the description
no longer wraps early.
Also stop a wide code snippet from pushing the dialog off-screen on
narrow viewports: AlertDialogHeader is a grid with place-items-center,
which sized the content row to its content; give the row w-full so it
fills the track, and add min-w-0 down the results chain so the snippet
scrolls inside its card instead of widening the dialog. Verified aligned
and contained from mobile portrait through ultrawide.
* Treat a repo as GGUF-only only when it ships no transformers weights
_is_gguf_repo excluded only .safetensors, so a repo with a .gguf and a
pytorch_model.bin (or .pt/.pth/.h5/.msgpack/.onnx/.ckpt) and no
safetensors was treated as GGUF-only and skipped the consent scan, even
though transformers can load that weight set and execute the repo's
auto_map code. Require the absence of ANY transformers-loadable weight
before treating the repo as a llama.cpp-only GGUF load. A genuine
GGUF-only repo (only .gguf) is still inert; a mixed repo with any pickle
or safetensors weight is gated. Adds a regression test across all the
non-safetensors weight formats.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Block flagged subdir weight shards referenced by a root index
The malware gate treated every subdirectory file as non-loadable, but
from_pretrained deserializes a subdir shard a root index references
(pytorch_model.bin.index.json -> shards/...-00001-of-00002.bin). Read the
root weight indexes and block a flagged subdir pickle the weight_map
points at; a flagged subdir pickle no index lists (NeMo nemo/*.distcp)
stays non-blocking, and an inconclusive index lookup fails closed.
* Pass hf_token to the export checkpoint load
ExportBackend.load_checkpoint scanned with hf_token in the worker but
loaded the weights unauthenticated, so a gated/private checkpoint passed
preflight then 401'd at from_pretrained. Add hf_token to load_checkpoint
and forward token to every from_pretrained branch; the worker passes the
command's hf_token.
* Scope created_by_scan to every HF cache the discard searches
created_by_scan used get_cache_path (active HF_HUB_CACHE only) while
/discard-remote-code deletes across active, legacy, and default caches. A
repo the user already had in a legacy/default cache was marked
scan-created and deleted on decline. Check all three caches for the repo
dir before declaring the scan created it.
* Scan the full .py closure of external auto_map repos
An auto_map cross-repo ref (owner/name--module.Class) only had its entry
file downloaded, but transformers also fetches that file's relative
imports from the same repo, so a dangerous helper.py was left outside the
scanned fingerprint. List each external repo's .py and scan the whole set
(plus the referenced entry files); fail closed if the repo cannot be
listed or fetched.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Fail closed when a weight index cannot be fully read
_indexed_shard_paths treated a partial result as definitive: if one weight
index read cleanly but another failed transiently, it returned the shard
paths it did see. A flagged subdirectory pickle listed only by the index we
could not read would then be classed as "not a load input" and skipped,
re-opening the very fail-open this guard was added to close.
Return None whenever any index read is inconclusive, even if another read
cleanly, so the caller blocks the already-flagged subdir pickle. A repo that
ships no index files raises EntryNotFoundError for each (never inconclusive)
and still returns an empty set.
* Match cached repos case-insensitively in the created_by_scan guard
_repo_in_any_hf_cache resolved casing only against the active cache and then
probed every cache with an exact directory name. A case-variant already
present in a legacy or default cache (models--Unsloth--Foo for a scan of
unsloth/foo) was missed, so the repo was marked created_by_scan and deleted
on decline -- but discard_remote_code_download deletes case-insensitively,
so that delete would hit the user's pre-existing cache entry. Detect
case-insensitively too, mirroring the deletion path.
* Skip remote-code and security review for selected GGUF variants
validate_model ran the trust_remote_code and Hugging Face security-scan
preflight against the repo even when the selected artifact is a .gguf. A
GGUF loads through llama.cpp, which never executes the repo's auto_map
Python and never deserializes root pickle weights, so repo-level Transformers
artifacts (a config.json with auto_map, or an unsafe pytorch_model.bin next
to the .gguf in a mixed repo) are inert for that load. Gating the GGUF on
them is a false positive. Run both preflights only for non-GGUF loads.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Scope the malware gate to actual load roots and serialized files
Two fixes to evaluate_file_security so it neither misses a load-path pickle nor
false-blocks an inert file:
- Honor subdirectory load roots. Spark-TTS / BiCodec call from_pretrained on the
snapshot's LLM subdirectory, so a flagged pickle directly under it is a
root-level load artifact there. A new load_subdirs parameter (set from the
model's audio type via security_load_subdirs) reclassifies those files relative
to the load root and looks for weight indexes under it, so a flagged shard in
that subdir is no longer skipped as "not root-level".
- Exempt source files. A root .py is never deserialized by from_pretrained;
executable repo code runs only through auto_map, which the remote-code consent
gate scans. Flagging a Python helper here would false-block a repo that merely
ships a build or train script.
* Scan a LoRA adapter and base as one consent unit, and gate MEDIUM code
A LoRA load runs both the adapter's and the base's repo code. The consent gate
scanned them separately and pinned one fingerprint per repo, so an adapter that
shipped its own auto_map code was either never shown in the dialog (which only
saw the base) or impossible to approve with the base's fingerprint.
evaluate_remote_code_consent_for_targets now scans all of a load's repos as a
single combined unit and pins ONE fingerprint over the union of their code, so
approving the load approves every repo's code together. evaluate_remote_code_consent
becomes a thin single-target wrapper, and an unscannable target fails the whole
load closed.
Also gate MEDIUM findings: like HIGH they now block pending pinned approval, so a
direct API caller cannot run flagged code by setting trust_remote_code=True
without consenting. Only a clean scan loads without a fingerprint.
* Preflight a LoRA load's adapter and base as one combined consent scan
scan_model_remote_code rewrote a LoRA adapter to its base and scanned only the
base for remote code, so the dialog never surfaced an adapter's own auto_map
code. Scan the adapter and base together through
preflight_remote_code_consent_for_targets, which pins one combined fingerprint
the worker gate accepts. The malware preflight is also scoped to each target's
load subdirectories.
* Apply combined consent and subdir-aware malware scan in load workers
Each load worker (inference, export, training) evaluated remote-code consent
once per target with a single shared fingerprint, so a LoRA adapter that ships
its own auto_map code could not be approved by the base's fingerprint. They now
scan the adapter and base together via evaluate_remote_code_consent_for_targets,
which pins one combined fingerprint over the union of their code. The malware
scan in each worker is also scoped to the model's load subdirectories so a
flagged pickle under a from_pretrained load subdir is not missed.
* Report a consistent trust_remote_code requirement after a model loads
validate_model reports requires_trust_remote_code from the YAML default OR the
raw auto_map, but the load, already-loaded, and status responses reported only
the YAML default. A custom-code model approved and loaded via auto_map was then
reported as not requiring trust_remote_code, so the frontend stored false and a
later retry or rollback sent trust_remote_code=false and failed.
A shared resolver reports the same requirement for a loaded model (a value
stored at load time, else the trust_remote_code the load used, else the YAML
default, else the raw auto_map check), and the load response persists it so the
status and already-loaded paths stay consistent. The selected-GGUF security
review is also scoped to the model's load subdirectories.
* Run the consent gate on training resume and for YAML-only trust_remote_code
Three frontend gaps left a model loading without the trust_remote_code it needs:
- The shared consent helper returned early when the scan found no auto_map and no
unsafe files, dropping a requirement that comes from a model's Studio YAML
default (e.g. GLM-4.7-Flash). It now grants the caller's requirement with an
empty pin instead of sending trust_remote_code=false.
- Resume-from-history called startTraining directly with no consent gate, so a
resumed run whose model needs custom code (or an old run with no approved
fingerprint) hit the worker block with no dialog. It now runs the same gate as
a fresh start.
- HF export passed requiresTrustRemoteCode=false for every HF source, so a
YAML-only model could not flip the flag before export. It now signals the
requirement for HF sources.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Cover both LoRA repos in validate, report GGUF as inert, purge all declined repos
Three follow-on gaps from the combined adapter+base consent work:
- validate_model resolved requires_trust_remote_code from the base alone, so a
LoRA adapter that ships its OWN auto_map code (with a plain base) was reported
as not needing trust_remote_code and the consent dialog never opened. It now
checks the [adapter, base] target set, matching the scan route and the workers
(which already gate both) and the security review already running over both.
- The already-loaded, loaded, and status responses for a selected GGUF reported
requires_trust_remote_code from the model's YAML default. A GGUF loads through
llama.cpp, which never executes the repo's auto_map Python, so the requirement
is inert for that load. They now report False, matching validate_model (which
already skips both gates for GGUF) so a status refresh cannot flip the flag
back on.
- The remote-code scan downloads both the adapter's and the base's config, but
created_by_scan tracked only the primary, so a base the scan was first to pull
into the cache was left on disk when the user declined. The scan now reports
scan_created_repos (every repo it newly cached) and the decline cleanup purges
each; created_by_scan stays for older clients. The frontend falls back to the
primary flag when the list is absent.

* Scan the repo the load fetches, purge external code on decline, harden consent pins
Six follow-on hardening fixes from a fresh review pass over the gate:
- The malware gate scanned the literal "Spark-TTS-0.5B/LLM" alias, but the trainer
downloads it as unsloth/Spark-TTS-0.5B and loads LLM/, so the alias 404'd and
failed open, missing a flagged LLM/ pickle. evaluate_file_security now resolves
the alias to the repo the loader fetches and scans LLM/ as a load root.
- security_load_subdirs relied only on tokenizer detection, which fails on an
unresolved alias or offline; it now also honors the Studio YAML audio_type
default, so a BiCodec LLM/ load root is not missed.
- The remote-code scan downloads external auto_map repos (owner/name--module.Class),
but the decline cleanup tracked only the model/adapter/base, leaving the external
untrusted code cached. The scan now enumerates external auto_map repos and reports
the ones it created in scan_created_repos, so a decline purges them too.
- External auto_map refs failed the whole load closed on a stale or mis-derived
dotted ref (sub.mod.py vs the real sub/mod.py) even though the actual file was
present and scanned. They now drop such refs when the repo listing is real, exactly
like the own-repo path; an empty/incomplete listing still fetches and fails closed.
- The combined consent fingerprint keyed code by the raw target string, so the scan
endpoint's canonicalized casing and a worker's raw user input produced different
pins for identical code, rejecting a valid approval. Hub repo ids are now folded to
lowercase in the key (local paths stay case-sensitive), so the pin tracks the code.
- Export threaded hf_token into the weight load but not into detect_audio_type /
is_vision_model, so a gated multimodal base 404'd in detection and fell through to
the text loader. Both probes now use the same token.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Thread the token through check-vision and guard the gate's parallel sites
The /check-vision endpoint classified a model without the hf_token, so a gated or
private vision model 404'd in the probe and was reported as a plain text model --
the same dropped-token shape as the export probes, at a sibling site. It now passes
the token like the neighboring /check-embedding endpoint.
Add deterministic consistency guards (tests/test_security_gate_consistency.py) that
enumerate the gate's parallel sites mechanically instead of relying on a review to
spot a missed sibling: every is_vision_model / is_embedding_model / detect_audio_type
caller under routes/ and core/ must thread the token, every GGUF response must report
trust_remote_code via the resolver or False (never the raw YAML default), and every
load worker that runs the malware or consent gate must resolve the LoRA base. A new
site that drops the token or mis-reports the requirement now fails CI directly.
* Narrow the LLM alias rewrite and make audio detection token-aware
Three fixes from the confirmatory review, one a regression from the previous round:
- _load_scan_target rewrote EVERY remote repo ending in "/LLM" to unsloth/<parent>,
so a real third-party repo named "<owner>/LLM" was scanned as unsloth/<owner>
while the loader still fetched the real repo -- a fail-open hole introduced when
the Spark-TTS alias handling was added. It now rewrites only a registry-known
bicodec alias; every other "/LLM" repo is scanned as itself.
- detect_audio_type cached results under the bare model name, so an unauthenticated
probe of a gated/private repo cached None and poisoned a later authenticated call
with the token. The cache is now keyed by (normalized_name, token_fingerprint),
matching the vision cache.
- The training fallback /check-vision call dropped the hf_token, misclassifying a
gated/private VLM when the config endpoint failed. It now passes the token, like
the getModelConfig call it falls back from; checkEmbeddingModel takes the token too.
Extend the consistency guards: every capability cache must be keyed by a tuple
including the token, so a cache re-declared as Dict[str, ...] fails CI.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Document the broad .py scan as deliberate and enforce it with a test
The remote-code scanner scans every .py in a repo once an auto_map exists, not
just the auto_map entry's static import closure. This is intentional: the entry
module can reach a sibling via an absolute import, importlib, or exec, none of
which a static relative-import closure follows, so closure-only scanning would be
a real bypass of a load-time RCE gate. The broad scan never under-scans; the cost
is that an unrelated benign script can over-block, which is the safe failure
direction (HIGH stays approvable; only CRITICAL hard-blocks).
Spell this out at both the local and remote scan sites so the choice reads as
deliberate, and add a test asserting an unrelated, never-imported .py is still
scanned -- so a future narrowing to the static closure fails CI.
* Purge a declined remote LoRA adapter the scan downloaded
scan_model_remote_code probed the created-by-scan state AFTER resolving the base,
but get_base_model_from_lora_identifier downloads a remote adapter's own
adapter_config.json, so the adapter looked already-cached and was dropped from
scan_created_repos. On decline the adapter -- including the auto_map .py the
preflight fetched -- was left on disk, defeating the "untrusted code is not left
on disk" guarantee for the adapter itself.
Snapshot the primary's cache state BEFORE base resolution and use it when marking
the adapter scan-created; on any probe error treat it as pre-existing so a decline
never deletes it. The base and external repos are unaffected (their configs are not
downloaded before their own probe). Add a test that models the mid-scan download
side effect, which the prior static-stub tests did not.
* Clear remote-code approval when the training model changes
Switching the training model from an approved custom-code model to a clean one
kept the previous model's trust_remote_code=true and approved fingerprint in the
store: setSelectedModel reset visionImageSize on a true switch but not the
remote-code approval. The clean model then trained with trust_remote_code=true,
which bypasses the compiler and disables fused cross-entropy.
Reset trustRemoteCode and approvedRemoteCodeFingerprint on a true model switch.
The new model's own YAML default is re-applied by loadAndApplyModelDefaults, and a
custom-code model still re-opens the consent dialog before training starts, so the
only change is that a clean model no longer inherits a stale approval.
* Trim verbose comments across the model-fetching hardening changes
Condense the explanatory comments and docstrings introduced across the
trust_remote_code consent gate, the malware/unsafe-file gate, the remote-code
scanner, the load workers, the model routes, and the security frontend into
fewer, tighter lines while preserving every security rationale (fail-open vs
fail-closed direction, the deliberate broad-scan anti-bypass note, the
empty-vs-unscannable distinction, stale-ref handling, and the alias-rewrite
spoof guard).
Comments and docstrings only. No code, logic, identifiers, or test behaviour
changed; verified comment-only via the AST/TypeScript checker (40/40), with the
backend test suite and frontend tsc green.
* Do not cache transient audio-detection failures
detect_audio_type cached _detect_audio_from_tokenizer's result
unconditionally, so a transient read failure (network error or 5xx,
returned as None) poisoned the cache and the later successful probe never
ran. Mirror the vision cache: _detect_audio_from_tokenizer now returns
(audio_type, definitive) and the caller caches only definitive results.
A read that succeeds with no audio tokens, or clean 404s for every
tokenizer path, stays a cacheable None; only a genuine transient failure
(connection error, timeout, 5xx, malformed body) skips the cache so the
next call retries.

* Studio Hub: default downloads to Xet transport
Model and dataset downloads defaulted to HTTP; flip the default to Xet for faster parallel chunked transfers.
- Frontend: DEFAULT_TRANSPORT_MODE is now Xet, so a user with no saved preference starts on Xet. effectiveTransportMode() already downgrades to HTTP and warns when hf_xet is unavailable, so this degrades gracefully.
- Backend: DownloadModelRequest.use_xet and DownloadDatasetRequest.use_xet default to True, keeping the API in step with the UI. Set use_xet=False for sequential HTTP Range-resume.
- Align the internal _spawn_download_worker default so no caller silently falls back to HTTP.
Inference and training model loads were already Xet-first with an HTTP stall fallback, so this brings explicit downloads in line with the rest of Studio.
* Studio Hub: gracefully fall back to HTTP when Xet is unavailable
With Xet now the default, an omitted or explicit use_xet=True from a non-UI API caller would 400 on installs without hf_xet, since resolve_transport raises when the transport is unavailable.
Add resolve_effective_use_xet(), which downgrades a Xet request to HTTP (with a warning) when hf_xet is missing, mirroring the frontend's own downgrade. Both the model and dataset flows now derive a single effective use_xet and feed it to resolve_transport and spawn_worker, so the recorded transport and the worker env can never disagree. The UI is unaffected: it already resolves availability and passes use_xet explicitly.
* Add tests for resolve_effective_use_xet Xet to HTTP fallback

* Studio Hub: show Google logo for diffusiongemma and future gemma derivatives
The provider-logo matcher only did a startsWith() prefix match, so qualifier-prefixed family names like diffusiongemma-* never matched Google's gemma- prefixes and fell back to the owner-initial (Unsloth U) tile.
Add an optional per-provider stems list: a case-insensitive substring fallback that runs only after every prefix misses, so prefix precedence (e.g. DeepSeek-R1-Distill- over Qwen) is preserved. Google gets stems: [gemma], which future-proofs the whole *gemma family (paligemma, codegemma, diffusiongemma, etc.) without enumerating each one.
* Studio Hub: match gemma stem only at a word boundary
Address review: a plain substring stem could over-match contrived names like gemmafy or gemman. Require the stem to end at a word boundary (next char not a letter), so gemma still catches diffusiongemma- and gemma-3n but never gemmafy. Splitting on delimiters would not work here, since the qualifier and family share one token (diffusiongemma).

* Studio: make sidebar nav hover a fully rounded pill
The single-line sidebar rows used rounded-[14px], so the hover and active highlight was a soft rounded rectangle. Switch the main nav, the recents/projects rows, and the account row to rounded-full for a fully rounded pill. The multi-line training-history rows keep rounded-[14px], since a full pill on a two-line block rounds the corners too aggressively.
* Studio: drop now-redundant collapsed rounded-full on sidebar buttons
With the base class now rounded-full, the group-data-[collapsible=icon]:!rounded-full override resolves to the same radius, so remove it from the two nav buttons. The avatar keeps its modifier, since its base is not rounded-full.
* Studio: make toast text selectable
Toast messages could not be highlighted or copied. Sonner's per-toast onPointerDown calls setPointerCapture(), which steals the mouse drag and stops the browser from starting a text selection. dismissible:false stops the capture but also disables the close button (same flag gates its onClick).
Wrap the Toaster in a capture-phase pointerdown handler that swallows the event on toast text only, never on its buttons, so text becomes selectable while the close button and auto-dismiss keep working.
* Studio: harden toast pointerdown guard for non-HTML targets
Cast event.target to Element (closest() lives on Element, so SVG icon targets are covered too) and guard that closest is callable before using it.
* Studio: stop the llama.cpp update banner flickering and show the download size
The banner animated in and out with a motion opacity + scale + translate
transition. That transform/opacity transition promotes a GPU compositing
layer whose first and last frame can flash for a moment on real displays,
which reads as a flicker on appear and again on dismiss/snooze. Drop the
animation and render the banner as a plain conditional mount: it appears
and leaves cleanly with nothing to flash.
Also surface the download size. update-status now reports the size of the
prebuilt that Update would fetch (the latest-release asset matching this
host's bundle), and the banner shows it as whole MB next to the no-restart
note, so the cost of the update is clear before clicking.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Show llama.cpp update size for upstream and source-build installs
update_download_size_bytes now accepts the upstream ggml-org ubuntu-/win-
asset suffixes and falls back to the marker's binary_repo, so the size
resolves for CPU/ROCm prebuilts (the fork publish repo only carries the
app-* and macOS bundles). The source-build update path now populates
update_size_bytes from the resolved asset, matching the marker path.
Both fail open to null. Adds regression tests for the upstream and
source-build size lookups and the route field round-trip.

Set ThemeProvider defaultTheme to "system" and enable system preference so the app follows the OS theme. In the theme store, apply the resolved theme to the document immediately on mount so the store is the single source of truth and avoids an initial light flash on fresh origins (e.g. empty localStorage). Minor comment and formatting tweaks in setTheme were also made.

* fix(hub): stop demoting cached gguf variants on mmproj or filename mismatch
- bug: a quant with its bytes on disk was marked not fully downloaded when the API-preferred main filenames did not match or the mmproj adapter was absent
- fix: fall back to the on-disk quant byte signal, the same one inventory uses for on-device, so a present quant is no longer demoted
- broaden mmproj detection to accept any mmproj-looking cached file, not only the API-preferred name
* feat(hub): full-page redesign with trending feed, search, and persisted state
- convert the hub to a full-page view with a new layout, model cards, and a sortable models table
- add a trending/latest/finetune feed with model and section deep-link params validated on the hub route
- add recent searches and rework model and dataset search with pagination and infinite scroll
- persist feed and token state through a dedicated store and persist-storage layer
* fix(hub): browse sorting, deep-link presets, dataset URLs, and persistence
- sort dropdown: drive HF-wide browse across all repos by the chosen sort, respecting format and capability filters
- section deep-link: apply the section preset (format and sort) on refresh and deep-link, not only on click
- dataset detail URL: persist the resource kind so refresh and share resolve datasets correctly
- gguf card: show a Loading state for hub-cache dir-path repos via repo-id match
- active-model CTA: New Chat now actually opens a fresh chat
- persist-storage: fix throttle keying with a Map and dedupe a duplicated util
- transport-toggle: drop redundant controlled-tooltip state
* Studio: polish hub redesign UI and unify segmented tabs
Refinements on top of the hub full-page redesign:
- Unify every segmented control (Discover/On Device, models/datasets,
Unsloth/All, recent/name/size, settings tabs, train dataset source,
profile shape, theme, OS toggle) on one filled-pill design.
- Hub list now loads in larger batches with a shorter fetch interval so
results fill in fast instead of dripping one row at a time.
- Disable remote avatar fetches in list rows and brighten the colored
initial fallbacks so they read clearly without network calls.
- Add a split master-detail view for model lists and make it the default.
- Left-align the split "Showing GGUF models" header with the rows below.
- Round the "Load more" footer box and tidy On Device stats layout.
- Show recent trainings on Recipes and Export, falling back to recent
chats when there is no training history.
* Studio: address hub review comments (filter warning + scrollMargin)
- DiscoverFetchMoreFooter only shows the "results may be hidden by your
filters" note when a filter is actually active, instead of always.
- Use the destructured scrollMargin prop directly in the row transform
rather than reaching into virtualizer.options.scrollMargin.
* Fix/adjust Hub metadata and deep links for PR #6349
* Studio: drop avatar ring in hub split view
The split master-pane rows (discover + on device) added a ring-1 around
the owner avatar that read as a shadow. Remove it so split-view avatars
match the flat avatars elsewhere; grid cards and the full list keep theirs.
* Studio: hub sort + scope as dropdown pills beside view tabs
Recent/Name/Size and Unsloth/All were segmented controls that dropped to
their own row in the narrow split pane. Make each a compact dropdown pill
(HubOptionMenu) that sits in the header actions slot next to the view-mode
tabs in every layout, so split view no longer needs a separate row.
* Studio: align hub list header with the view tabs and rows
- Vertically center the "On device" / "Showing GGUF models" title with the
dropdown pill and view-mode tabs (items-center instead of items-end), so a
short title no longer sits low against the taller tab row.
- Nudge the back chevron 2px further left (-ml-2) so its glyph edge lines up
with the start of the row hover below it.
* Studio: align back chevron tip with the row hover edge
The arrow glyph is inset ~6px inside its centered icon box, so an
edge-aligned button left the visible chevron sitting in from the column.
Pull the button out (-ml-3.5) so the chevron tip lands on the row hover's
left edge instead of floating to its right.
* Studio: unify every bare tick on the shared check mark
Point all plain checkmarks at the canonical @/lib/tick-icon tick (the one
already used in the chat composer and menus), so there is a single tick
across the app:
- Hub: model-inspector, hub-option-menu, path-info-button were importing
the stock hugeicons Tick02Icon; switch them to the shared icon.
- Chat / assistant-ui: artifact-surface, prompt-storage-dialog, reasoning,
tool-ui-python, tool-ui-terminal, tool-ui-code-execution, and the
tool-fallback status map used lucide CheckIcon; render the shared tick
via HugeiconsIcon instead (tool-fallback wraps it to fit its icon map).
The circular CheckmarkCircle success badges are intentionally left as-is.
No bare CheckIcon/stock Tick02Icon references remain; verified the tick
renders in every converted spot via typecheck + build.
* Studio: nudge back chevron 2px right
-ml-3.5 pushed the chevron a touch too far left; -ml-3 sits it just
inside the row hover edge, aligned with the avatars below.
* Studio: search base-model chips across all publishers
Clicking a Base model chip searches the Hub for the upstream repo, which
lives under another publisher (google, meta, etc.). It left ownerScope at
the default "unsloth", so the search hard-restricted to the Unsloth org and
could never surface the base model. Switch the scope to "all" for this action.
* Studio: label the safetensors list header "Safetensors"
The focused list heading showed "Showing Checkpoint ... models" while the
format dropdown labels the same checkpoint filter value "Safetensors". Match
the dropdown so the header reads "Showing Safetensors ... models".
* Studio: simplify the focused list heading to "Models"
Drop the format/capability composition (e.g. "Showing Safetensors Reasoning
models") so the focused list heading just reads "Models" (or "Datasets").
Search keeps its "Results for ..." label.
* Studio: drop the header refresh button to the text baseline
The refresh button sat at the heading's vertical centre. Nudge it down so
it lines up with the bottom of the title text instead.
* Studio: hide redundant "Back to Hub" in the split detail pane
In split view on large screens the master list sits beside the detail, so
the back button is redundant. Hide it there (lg) and reclaim the top space.
It stays on the small-screen overlay and the full-page detail, where the
list is hidden and back is the only way out.
* Studio: match the readme scroll fade to the left column
The detail pane relied on the sticky back-bar's fade, which is now hidden in
split view. Add the same hub-scroll-fade overlay the master list uses so the
readme fades consistently at the top when scrolled. The back-bar, when shown,
sits above and covers it.
* Studio: align Hub refresh button to the heading text bottom
* Studio: nudge Hub refresh button up to the heading text
* Studio: optically centre the HF token shield in its circle
* Studio: preview the first visible on-device row in split view
* Studio: calm the on-device row colour and fix size tooltip contrast
* Studio: fix Hub reset tab and clear search when opening a section
* Studio: fix Hub feed defaults, filter sync, and GGUF vision download state
* Studio: condense Hub redesign code comments

* Studio: auto-render fenced HTML in chat replies as canvas cards
After an assistant reply finishes, append a clickable canvas card for each fenced html block in its text, with no render_html tool call and no extra message. Fragments and non-collapsed documents are covered; full documents already collapsed in place and blocks rendered by the render_html tool are skipped so nothing shows twice.
Hoists the fence helpers out of markdown-text.tsx into a shared module (html-fences.ts) and adds a line-based multi-fence scanner so several html blocks in one reply are all found.
* Studio: add HTML Code button to canvas cards and keep diffusion code visible
When Canvas mode is on or a diffusion model is loaded, the canvas card shows a Preview and an HTML Code button side by side; Code opens the panel source view. The requested view is threaded through openArtifact so the surface opens to preview or code.
Diffusion no longer collapses its full HTML answer, so the raw code stays in the message and the trailing canvas card is appended next to it.
* Studio: drop the Code button on diffusion cards since their code is already inline
* Studio: address review feedback on HTML canvas auto-cards
- Build the fence-body indent regex once per fence instead of per line.
- Only skip full-doc fences the in-place collapse can render (plain
unindented triple-backtick), so 4-backtick or indented docs still get a card.
- Scan each text part on its own so a fence cannot stitch across a tool,
source, or reasoning part.
- Exclude diffusion replies from the collapse/skip gates and the card Code
button, since diffusion keeps its HTML inline.

* Add Studio API activity monitor
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Mark disconnected monitor streams cancelled
* Fix monitor lifecycle, parsing, and clock issues for PR #5558
Backend:
- Finalize the monitor entry as error on the chat-completions validation
reject paths (addresses the codex P2 comment around line 2337). Adds a
small _reject helper next to the api_monitor.start so each early-raise
in the GGUF tool-passthrough, non-empty-messages, GGUF vision/audio,
PIL image decode, and text-only model branches no longer leaves the
entry stuck running until eviction.
- _monitor_openai_chunk is now defensive about malformed shapes
(non-list choices, non-dict choice/delta) so a misbehaving provider
chunk does not raise into the streaming generator and abort the
user's response.
- _monitor_openai_sse_line accepts both data:value and data: value per
SSE spec; previously the single-space-only prefix silently dropped
tokens from compact emitters.
- openai_completions stream now keeps a residual buffer between
aiter_bytes chunks so a data: line whose newline lands in the next
TCP frame is reconstructed before parsing, instead of being dropped
by the per-chunk splitlines call.
api_monitor:
- duration_ms is derived from time.monotonic anchors and clamped at 0,
so NTP / manual clock steps no longer produce negative durations.
- finish() and fail() are idempotent: a second call (for example [DONE]
arriving after the generator's finally block already ran) no longer
moves finished_at or finished_monotonic.
- set_usage only derives total_tokens when no authoritative total has
been recorded, so a later partial-usage chunk does not clobber a
provider-reported total from an earlier chunk.
- _trim guards limit < 3 so the slice cannot underflow.
Tests:
- Adds regression coverage for the new idempotency, total preservation,
monotonic clock, and _trim guard behaviour.

* Chat search: match across all messages, not just title and preview
The Cmd/Ctrl+K chat search only matched the thread title and a 120
character preview of the newest message, so keywords anywhere else in a
conversation were unfindable. Build a per-thread haystack from the title
plus every message's text and match against that.
The haystack is lowercased once at index build time, so the keystroke
filter only normalizes the short query instead of re-lowercasing the
whole conversation per item.
* Chat search: search user messages first, expand to all only if no hit
User messages are short while assistant replies can be very long, so
matching the whole conversation on every keystroke scales with the
assistant text. Store a separate userSearchText (title plus user
messages) and match it first, expanding to the full per thread
searchText only when nothing matches user text anywhere. Row filtering
moves into selectVisibleChats with cmdk shouldFilter disabled so the
tier choice is deterministic.
* Chat search: include tool calls and sources in the full-text tier
extractText now also pulls reasoning/thinking, tool call name/args/result
and cited source title/url, so the expanded full-conversation tier finds
keywords that only appear in tool activity. Drop the now-unused preview
field since search no longer matches on it.
* Chat search: drop base64 image/audio payloads from the index
extractText stringified tool-call results wholesale, so an
image_generation result (image_b64) or audio payload would pour megabytes
of base64 into searchText and get lowercased on every rebuild. Add
searchableText, which keeps readable tool args/results (tool name, prompt,
text) but skips binary keys and strips data URLs, long base64 runs and the
__IMAGES__ suffix.

* Studio: use the shared spinner for loading toasts
The loading toast used a different spinner from the model download toast,
so 'Unloading model' and 'Downloading model' looked inconsistent. Switch
the sonner loading icon to the app-wide Spinner so they match.
* Studio: consolidate loading spinners onto the shared Spinner
Replace the duplicate ToolCallSpinner and the remaining inline loading
spinners (hugeicons Loading03, lucide Loader2/Loader/LoaderCircle, and
the hand-rolled border rings) with the shared Spinner component, then
delete tool-call-spinner.tsx. Refresh and regenerate action icons and
the shimmer button are left alone since they are not loading spinners.
* Studio: align and even out sidebar hover pills
The Recents chat rows started further left than the nav items above them
and the hover pill widths varied. Give every nav and chat group the same
pl-1.5 pr-2 so the pills line up and share one width, and on hover the
chat rows only reserve room for the kebab so the title keeps one more
character.
* Studio: address review feedback on spinner and sidebar polish
- recipe-graph-node: restore rounded-full bg-background on the spinner
wrapper so it keeps masking the grid lines behind the floating spinner
(the original hand-rolled ring had this mask).
- app-sidebar: revert the pinned-row open-state padding to pr-8 so the
unpin button stays clear of the title when the kebab menu is open.
- app-sidebar: correct the now-stale inset comment (pl-1.5 = 6px, 18px).
* Studio: fix Mac IME input-method switch leaving composer Send disabled
On macOS, switching input method (Ctrl+Space / menu-bar language icon)
fires compositionstart but never compositionend — leaving composingRef
pinned at true and the Send button permanently disabled even after
switching back to English.
Two immediate recovery paths added to useImeComposerInputHandlers
(thread.tsx) and SharedComposer (shared-composer.tsx):
* onKeyDown else-if: clears composingRef on the first non-IME keystroke
after a stuck composition, unblocking Send on that very keydown rather
than waiting for the 2500ms watchdog.
* onBlur handler: clears composingRef unconditionally on textarea focus
loss — safe because the OS always commits or cancels any active
composition before surrendering focus to another element.
Two new Playwright regression steps (6e, 6f) added to
playwright_chat_ime_i18n.py assert recovery within 1500ms (well below
the 2500ms watchdog), covering both recovery paths.

* Studio: add --secure Cloudflare-only mode and revamp API usage examples
--secure / --not-secure on `unsloth studio` and `unsloth studio run`:
- --secure binds 127.0.0.1, requires the Cloudflare tunnel, and advertises only
the Cloudflare link. cloudflared reaches the server over localhost, so the raw
port is never exposed on a public interface.
- If the tunnel cannot start, fail closed with a clear message instead of
silently leaving a raw 0.0.0.0 link.
- Default stays not-secure (no behavior change); coexists with the existing
--cloudflare/--no-cloudflare flag. Host defaults are unchanged.
- /api/health (authed) now reports the live tunnel URL.
API usage examples (Profile > API):
- Example tabs for curl, Python, curl + tools, Python + tools, plus an OS row
(Linux/macOS/WSL vs Windows) auto-detected from the platform.
- Windows curl passes the JSON body via a file so PowerShell does not strip the
quotes when calling curl.exe.
- Python + tools forwards enable_tools/enabled_tools through extra_body and
guards chunk.choices, since tool-lifecycle events carry no choices.
- Shows the loaded model name and the real API key while it is still revealed.
- A Cloudflare Tunnel toggle (default on) shows the public tunnel URL and uses
it as the base_url in the examples when a tunnel is running.
Tests cover the tunnel start gate and the --secure flag on both commands.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: gate --secure tools on public exposure and harden API examples
In secure mode the server binds loopback but is reachable via the public
Cloudflare tunnel, so resolve the tool policy against the public exposure
(0.0.0.0) rather than the loopback bind. This keeps server-side tools off by
default and prompts before enabling them, instead of inheriting the loopback
default of on. The startup tool notice now names the public surface.
Also reject --secure with --no-cloudflare directly in run_server and the
run.py argparse (not only the CLI), JSON-encode interpolated model names so
Windows paths and quotes cannot produce invalid JSON or broken snippets, and
force-refresh /api/health on the API panel so a tunnel that starts after the
first health read still surfaces its URL.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: API examples show direct host when tunnel toggle is off; move Copy onto code
The Cloudflare Tunnel toggle had no visible effect when Studio was opened
through the tunnel: the off state fell back to window.location.origin, which
equals the tunnel URL in that case. /api/health now reports the direct
host:port (server_url), and the API panel uses it for the off state so it shows
the real non-tunnel base. Also move the Copy button out of the tab row and onto
the code block.
* Studio: highlight API examples, add advanced tabs, fix tunnel toggle row
Syntax-highlight the curl/PowerShell/Python snippets with the app's shared
shiki plugin (bash/powershell/python). Add 'curl + advanced' and
'Python + advanced' tabs that set temperature/top_p/top_k/min_p/
repetition_penalty/max_tokens, enable thinking, and turn on all tools.
The Cloudflare Tunnel row no longer shifts the code block: the tunnel URL is
always rendered (dimmed when off) so toggling keeps the row height constant.
Key the highlighted block on its content so it remounts when only the base URL
changes (the renderer's block memo otherwise kept a stale URL).
* Studio: rename API tunnel toggle to Secure HTTPS, hint --secure when exposed
Rename the API examples toggle from Cloudflare Tunnel to Secure HTTPS. When the
server was not launched with --secure, show an info tooltip noting the raw
0.0.0.0 port is still globally reachable and pointing at --secure. /api/health
now reports whether --secure was used so the hint is hidden in secure mode.
* Studio: force tools off for plain network/secure launches
The plain 'unsloth studio --secure' (and '-H 0.0.0.0') launcher re-execs run.py
and never installed a tool policy, so the process default (honor per-request
enable_tools) let any API-key holder run Python/terminal tools over the public
endpoint. Force the policy off at the run.py entrypoint when network-reachable
(0.0.0.0 or --secure); 'unsloth studio run' still installs its own resolved
policy and does not go through this path.
* Studio: apply default tool policy in run_server, not the run.py entrypoint
The plain launcher runs from the studio venv and calls run_server directly, so
it never hit the run.py __main__ guard. Move the network/secure default-off tool
policy into run_server so every launch path (plain, --secure, direct run.py)
gets it; the run subcommand still overrides it with its resolved policy.
* Studio: clarify --secure help text on the network exposure tradeoff
Spell out in --help (both unsloth studio and unsloth studio run, plus the
run.py argparse) that --not-secure also serves the raw 0.0.0.0 port reachable
from anywhere on the network, matching the API panel's Secure HTTPS hint.
* Studio: cache API-key PBKDF2 derivation to cut per-request /v1 auth overhead
validate_api_key re-ran the 100k-round PBKDF2 on every authenticated
request, adding ~15ms to each /v1 call made with an sk-unsloth- key.
Benchmarked against the bare llama-server it proxies to, API-key requests
carried ~22ms of fixed overhead vs ~7ms for the JWT path; the gap was
entirely this redundant key derivation (Pydantic validation measured
0.005ms, so it is not a factor).
The raw-key to hash mapping is a pure deterministic function of the fixed
server salt, so memoize it per process, keyed by a salted HMAC of the key
(never the key or a recoverable digest). The cached value equals what is
already stored at rest. Revocation and expiry remain enforced by the
SQLite read on every call, so a cache hit only skips the KDF, never the
active or expiry checks. Only keys that exist in the DB are cached, so
unknown-key spam cannot grow it.
After the change the API-key /v1 overhead drops to ~8ms, at parity with
JWT, while the at-rest PBKDF2 hashing is unchanged.
Adds test_api_key_expiry.py covering API-key and JWT expiry enforcement
and the new cache: it skips the KDF on repeat and still rejects revoked
or expired keys.

* Studio: tighten comments across the secure-tunnel and API-key changes
Condense multi-line comments and docstrings to one or two lines, drop the
ones that restate obvious code, and remove an orphaned test section header.
Comment-only: verified with comment_tools.py check (9/9 code unchanged), the
auth/secure-tunnel/CLI test suites, and a clean frontend typecheck and build.

* Studio: Add inline confirmation (Allow/Always allow/Deny) for tool calls
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Fix race in tool-call confirmation gate
* Studio: gate built-in tool calls and harden the confirmation handshake
The Allow / Always allow / Deny controls only lived in the fallback tool
card, but the built-in tools (web search, python, terminal, code
execution, image generation) render with their own components and so
never showed the buttons. Those calls paused after tool_start with no way
to approve them, hanging until the 1 hour timeout. Only MCP tools, which
use the fallback renderer, actually worked.
Render the controls for every tool card by wrapping each registered tool
component (and the fallback) in thread.tsx with a shared
ToolConfirmationControls, so the gate applies uniformly.
Also make the handshake robust:
- The gate keys on a per-call approval_id minted by the backend and
echoed in tool_start, instead of session_id alone, so a stale or
concurrent confirmation can no longer resolve the wrong call.
- The approval slot is registered before tool_start is yielded, closing
the race where a fast click or an auto "Always allow" could reach the
backend before the waiter existed.
- The frontend resolves with the same session id the request was sent
with (plus the approval_id), fixing the new-thread mismatch where the
confirmation targeted a different session than the blocked stream.
- The confirm endpoint returns {resolved}; the UI keeps the buttons and
shows a retry hint until the backend confirms a match, instead of
hiding them on a failed or mistargeted post.
- The gate runs after the disabled-tool and duplicate-call checks, so a
call that will not execute is not put up for approval. A denied call is
still excluded from duplicate detection, so re-issuing and approving it
works.
- "Always allow" is scoped per session to match the backend gate.
Add backend tests for the approval registry, the SSE no-deadlock
handshake, and the loop integration (allow, deny, disabled, duplicate,
re-issue after deny).
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Move "Confirm tool calls" to the Tools section
* Studio: add Bypass Permissions (skip confirmation, disable tool sandbox)
Adds an opt-in Bypass Permissions toggle next to Confirm tool calls. When on,
no tool call shows a confirmation prompt and the python/terminal sandbox is
disabled: safety checks, command blocklist, and resource limits are skipped.
Secret env vars are still stripped and HOME stays repointed at the session
workdir. Default off keeps current behavior, and it takes precedence over
Confirm tool calls. Enabling it requires accepting a warning each time.
* Studio: harden Bypass Permissions secret handling and fix Anthropic tool path
Follow-up to the Bypass Permissions feature. Addresses the review findings:
- Anthropic /v1/messages 500: declare bypass_permissions on
AnthropicMessagesRequest so tool requests that omit the field default to
False instead of raising AttributeError (extra='allow' does not set absent
attributes).
- /proc parent-env leak: stripping the child env did not stop a same-uid
bypassed child from reading /proc/<parent>/environ to recover the
tool-executing process's unfiltered secrets. Clear PR_SET_DUMPABLE on that
process before the first bypass exec so its /proc entries become root-owned.
Hardening is fail-closed: if prctl is denied, bypass execution is refused
rather than run with the parent environ still readable. Mitigation, not a
full boundary; documented in the code.
- Broker/capability vars: strip SSH_AUTH_SOCK, SSH_AGENT_PID, GPG_AGENT_INFO,
GNUPGHOME, KUBECONFIG, DOCKER_HOST so a bypassed tool cannot use the
operator's live agents.
- Credential-bearing URL values: drop any env var whose value embeds URL
userinfo (scheme://user:pass@ and token-only scheme://token@) regardless of
the variable name. Benign proxy/index URLs without credentials are kept, so
proxy-only and internal-index setups still work in bypass mode.
- Windows temp isolation: repoint TEMP and TMP (not just TMPDIR) at the
per-session sandbox dir.
- Frontend: stop persisting bypassPermissions; a reload now starts with the
sandbox/confirmation bypass off and requires re-accepting the warning dialog.
Adds regression tests for each finding in test_bypass_permissions.py.

* Studio: strip cred-location env vars (HF_HOME etc.) in Bypass Permissions
Repointing HOME did not stop SDKs auto-reading cached creds via vars that
point at the real home/cache/config: HF_HOME (startup always sets it; token
lives under $HF_HOME/token), HF/XDG cache roots, NETRC/BOTO_CONFIG/
PIP_CONFIG_FILE, and Windows HOMEDRIVE/HOMEPATH. Drop those, and repoint
USERPROFILE/APPDATA/LOCALAPPDATA at the per-session workdir. Adds regression
tests.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: lock in bypass HF token resolution with an end-to-end test
The drop-based fix relies on the whole HF_HOME/XDG fallback chain being
removed so huggingface_hub resolves under the repointed HOME. Add a test
that sets HF_HOME and XDG_CACHE_HOME at a real cache and asserts the
resolved token path lands under the workdir, not the operator's cache.

* Studio: strip npm _auth, MYSQL_PWD, and BASH_ENV from bypass env
Three more credential vectors dodged the bypass scrubber: NPM_CONFIG__AUTH
(npm _auth, base64 so no URL userinfo and no AUTH marker), MYSQL_PWD (markers
use PASSWD, not PWD, since PWD is the cwd var), and BASH_ENV (bash -c sources
it for non-interactive shells, so a startup file can re-export stripped
secrets). Add an AUTH marker, the exact MYSQL_PWD name, and drop BASH_ENV plus
PGPASSFILE. Adds regression tests incl. an end-to-end check that a bypass
terminal call does not source BASH_ENV.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: extend bypass env scrubber and enforce confirm precedence in loops
From a parallel review pass over the bypass changes:
- Drop more credential-location vars in _build_bypass_env: npm/yarn/git/cargo/
rclone config pointers (NPM_CONFIG_USERCONFIG, NPM_CONFIG_GLOBALCONFIG,
YARN_RC_FILENAME, GIT_CONFIG_GLOBAL, GIT_CONFIG_SYSTEM, CARGO_HOME,
RCLONE_CONFIG) and the GIT_ASKPASS/SSH_ASKPASS auth helpers.
- Enforce confirm_tool_calls AND NOT bypass_permissions inside the safetensors
and GGUF tool loops, not just at the route, so a direct internal caller
passing both flags never prompts.
- Soften the toggle hint: environment secrets are stripped, but bypassed code
can still read files and credentials on the machine (no overclaim that keys
stay hidden).
Adds regression tests for the new names and the loop-level precedence.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: add GGUF loop test for bypass-over-confirm precedence
The safetensors loop precedence is covered behaviorally; the GGUF loop needs a
live llama-server so add an AST guard asserting its _needs_confirm gate
references both confirm_tool_calls and bypass_permissions, matching the other
llama_cpp source-inspection tests.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: add red Bypass Permissions badge in the composer
When Bypass Permissions is on, show a persistent red pill in the composer
tool-pill row (like the Search/Code pills), matching Claude Code's always-
visible bypass indicator. Clicking it turns bypass off, mirroring the other
composer toggles. Enabling still goes through the settings toggle + warning
dialog. Adds a data-variant=danger style for the destructive-colored pill.
* Studio: show Bypass Permissions badge in the Thread composer too
The empty-state and active Thread render their own composer (thread.tsx),
not shared-composer, so the badge only appeared in the split layout. Mirror
the red dismissible pill in ComposerAction so it shows in every composer.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: keep the Bypass Permissions badge visible when the composer is collapsed
The Thread composer only renders the pill row when expanded, so the active-mode
badge vanished on the default (collapsed) empty state. Render it before the
expand gate (it returns null when bypass is off) so the red indicator always
shows while bypass is on.
* Studio: make the Bypass Permissions confirm button a solid red button
The destructive button variant is a subtle 10% tint that read as bare red text
next to the outlined Cancel. Force the solid destructive fill (the variant's
class loses to the tint through AlertDialogAction's Slot merge, so use the !
override the codebase already uses for this case) and shorten the label to
'I understand' so it fits the small dialog's two-column footer.
* Studio: add Bypass Permissions to the composer + More menu
Adds a 'Bypass Permissions' entry to the composer plus-menu (under More by
default) in both composers, so it can be toggled without opening Run settings.
Enabling routes through the same danger warning dialog; disabling is immediate.
A shared BypassPermissionsMenuItem keeps the two composers in sync.
* Studio: harden bypass env scrubber for IMDS opt-out and connection strings
Two gaps in the Bypass Permissions secret scrubber:
- The broad AWS_ prefix also dropped AWS_EC2_METADATA_DISABLED, a non-secret
opt-out. Removing it re-opens the IMDS instance-role credential path that the
operator explicitly disabled, so a bypassed boto/AWS-CLI call could recover
cloud creds. Keep that flag (and AWS_EC2_METADATA_V1_DISABLED) via a keep-list
while still stripping the real AWS credential vars.
- Azure App Service connection strings (SQLCONNSTR_/CUSTOMCONNSTR_/...,
WEBSITE_CONTENTAZUREFILECONNECTIONSTRING) and values like Password=/AccountKey=
/SharedAccessKey= slipped past the name and URL-only value classifiers. Add
CONNSTR/CONNECTIONSTRING name markers and a connection-string value matcher.
* Studio: let Bypass Permissions suppress the confirm-tool-calls guards
The confirm-vs-bypass precedence (confirm and not bypass) was applied at the
loop call sites but not at the earlier request guards, so a client sending
confirm_tool_calls + bypass_permissions together was rejected (stream=true
required / unsupported for external or Anthropic tools) before the precedence
took effect. Gate all four confirm guards on not bypass_permissions so both
flags together proceed with the gate suppressed, matching the documented rule.

* feat: add Anthropic-compatible thinking parameter
Add `thinking` parameter using Anthropic's format ({type: 'disabled'} /
{type: 'enabled'}) alongside the existing `enable_thinking` boolean for
backward compatibility.
The new parameter is mapped internally to `enable_thinking` at the route
layer so all downstream templates and backends continue to work unchanged.
Changes:
- Add ThinkingConfig model and `thinking` field to ChatCompletionRequest
- Add mapping logic in routes: thinking.type -> enable_thinking
- Add `thinking` field to frontend TypeScript types
- Update frontend request building to send thinking parameter
- Add tests for new thinking parameter

* fix: move thinking→enable_thinking mapping to model_validator
The Gemini review correctly identified that the route-level mapping
bypasses normalization for external provider requests. Moving the
mapping into a @model_validator on ChatCompletionRequest ensures it
runs during Pydantic validation regardless of routing path.

* cast norm activation output back to original input dtype
* address mlx studio review feedback
* Fix present-but-None seed override for PR #5656
studio/backend/core/training/worker.py
`config.get("model_random_state", random_seed)` only fills the
default when the key is absent. When a caller passes
`config["model_random_state"] = None` explicitly (which happens
any time a JSON payload sends an explicit `null`), the old code
forwarded `None` to FastMLXModel and disabled deterministic init
silently. Same for `lora_random_state`. Treat absent and explicit
None the same way: fall back to random_seed.
studio/backend/tests/test_training_raw_support.py
Update the source-string assertions to match the new lines.
* Guard optional MLXTrainingConfig fields and normalize random_seed for PR #5656
The MLX worker now passes `cast_norm_output_to_input_dtype` and
`dataset_order` only when the linked unsloth-zoo dataclass actually
declares them. Released zoo trees that predate the paired PR can still
construct `MLXTrainingConfig` without raising
`TypeError: unexpected keyword argument`. Once the dependency floor is
bumped to a release that contains both fields, the feature-detect
guards become no-ops.
`random_seed = config.get("random_seed", 3407)` was unguarded against
explicit `None` from raw / backend callers. The same value seeded the
trainer and was the fallback target for `model_random_state` /
`lora_random_state`. Normalize once at the top of the function and use
the normalized value everywhere so an explicit `None` cannot reach
FastMLXModel / get_peft_model / MLXTrainingConfig.
Existing seed source-pattern test updated to match the new normalize
helper. New test asserts the feature-detection guards exist and that
the unconditional kwargs do not include the gated fields.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Normalize seed / cast / max_grad_value at TrainingBackend for PR #5656
Round-3 review consensus: the per-field guards that landed in the MLX
worker only protect the MLX path. The same `TrainingBackend.start_training`
config still reaches the CUDA/text trainer at `worker.py:2267`, the
embedding LoRA init at `worker.py:2450`, and embedding TrainingArguments
at `worker.py:2624` with raw `None` values, so an explicit
`random_seed=None` from a raw / backend caller still breaks non-MLX
training even after the previous fix.
Move the normalization into `TrainingBackend.start_training` itself,
where it runs once for every training mode:
- `_coerce_seed(value)`: explicit `None`, non-int, or absent all become
3407. Every downstream worker now sees an int.
- `_coerce_optional_bool(value, default)`: explicit `None` falls back
to `default` instead of `bool(None) == False`. Also normalizes the
common raw-config / YAML string aliases ("true" / "false" / "0" /
"1"). Used for `cast_norm_output_to_input_dtype`.
- `_coerce_optional_nonneg_float(name, value)`: rejects negative
numerics from raw / backend callers, matching the Pydantic
`ge=0` constraint the HTTP route already enforces. Used for
`max_grad_value`.
worker.py MLX path: the existing `bool(config.get(key, True))` for
`cast_norm_output_to_input_dtype` was changed to also fall back on
explicit `None`, so direct worker callers (bypassing
`TrainingBackend.start_training`) are equally safe. `max_grad_value`
also raises on negative values inside the worker for the same reason.
TrainingStartRequest.random_seed default bumped from 42 to 3407 so
direct REST callers that omit the field receive the same default as
the Studio frontend and the MLX worker.
New regression test exercises the three new helpers across explicit
None, valid values, string aliases, and negative-value rejection.
* Tighten feature-detect test paren tracking for PR #5656
The block-extraction used , which stops at the
first inner closing paren (e.g. )
and would silently miss a future unconditional
/ added later in the same dict literal. Switched to
proper paren-depth tracking so the unconditional block is checked end-to-end.
* Shorten verbose comments in MLX Studio backend
* Handle MLX Studio EOS appending by mode
* Wire MLX leaf norm clipping through Studio
* Respect VLM layer filters for explicit LoRA targets
Rationale / guardrails for the local Studio/vision push:
When callers provide explicit VLM LoRA target_modules together with layer filters, FastVisionModel still needs to route the explicit targets through get_peft_regex. Otherwise the layer filters are ignored and adapters can be attached outside the requested language/vision scope.
Do not revert this to plain list(target_modules) for explicit module lists. The CUDA/Studio-facing contract is that explicit targets and layer filters compose: target_modules selects module names, while finetune_language_layers / finetune_vision_layers / finetune_attention_modules / finetune_mlp_modules constrain where those targets are allowed.
The regression test covers the language-only explicit q_proj case and source-checks that explicit targets are wrapped through get_peft_regex when filters are active.

* Refresh MLX smoke clip-config note for leaf_norm default
Trim the 11-line comment block to 5 lines and correct the stale claim
that MLXTrainingConfig defaults to max_grad_value=1.0. The new default
is max_grad_leaf_norm=1.0 (same memory profile as elementwise but
direction-preserving). The smoke still pins max_grad_value=1.0
explicitly to keep the 13-seed pass-rate fixture stable.

Rename the banner heading from "New llama.cpp version" to "New llama.cpp
update", and add a small hint under the version line ("No restart needed
after update"). Tighten the gap above the action row so the hint and the
buttons read as one group.
* Studio: UI polish for sidebar, menus, hub and toasts
- Pinned chats: add a Pinned section above Recents with a Pin/Unpin menu
action and a hover unpin button on each pinned row
- Sidebar: align the Recents and Pinned section labels with Train, and
switch the chat Archive icon to archive-03
- Dropdown menus: pull separators in to match item width, and even out the
projects menu padding and radius to match the composer menu
- Account menu: match the divider width to the row hover width
- Hub toolbar: equalize the format, capability and sort filter widths so
the search field has more room
- Model run bar: make the quant selector hover a full pill
- Tooltips: slightly larger corner radius
- Auth: reduce horizontal padding on the submit button
- Toasts: center the model load content so top and bottom padding match
* Studio: shrink pinned unpin icon, match projects menu to composer menu
* Studio: inset dropdown separators slightly from item width
* Studio: move archived chats from the sidebar into chat settings
Archive now shows a toast pointing to Settings. Archived chats are listed
and managed (open, unarchive, delete) under Settings, Chat, Data.
* Studio: make the archive toast open the archived chats list
* Studio: keep chats archived when opened from the archived list
* Chat settings: optional delete confirmation and menu cleanup
Add a "Confirm before deleting" toggle in Settings > Chat > Data. When
turned off, deleting a chat from the sidebar skips the confirm dialog
and removes it instantly. The preference is stored client-side.
Add a separator above Archive in the chat row menu so Archive and
Delete read as a group separate from Export.
Drop the duplicate divider above "Clear all chats". The section already
draws a divide-y separator between rows, so the destructive row no
longer adds its own top border.
* Hub, dialog and page polish
Hub catalog:
- Drop "inference" from the Hub subtitle.
- Make the HF token shield a circle in the header.
- Equal, narrower filter triggers that stay a fixed width; long labels
truncate with an ellipsis instead of clipping.
- Tighter gap between the label and the dropdown chevron so one more
character fits.
- Keep the toolbar on one row at desktop widths.
- Align the model list and row hover with the Discover tab, add right
side breathing room.
- Make the dark-mode scrollbar lighter so it is easier to see.
- Filled size and quant chips no longer draw a border.
- Column divider uses the sidebar border color.
- Hub card extends into the bottom space.
Filters and channels:
- Add an MLX format option; detect MLX repos by library or tag.
- "Fine-tune ready" now includes 16bit safetensors, not only bnb-4bit.
- Shorten the curated channel descriptions.
Shared UI:
- New standard chevron icons (down and submenu right) shared across the
Hub, dropdown menu, menubar, project switcher and model selector.
- Dialogs get more top and bottom padding and a larger heading.
- Guided Tour hides itself on pages with no tour.
Other pages:
- Export and Data Recipes use the same page padding as the Hub.
* Soften popup overlays and refine hub filters
Dialogs, alert dialogs and sheets now use a light blur with a slight
darken instead of a heavy black scrim, so popups stay legible without
dimming the whole screen. Edit System Prompt and Edit Chat Template
drop their custom overlays and share the same look.
Also limit the Fine-tune ready channel to checkpoints Unsloth can
actually fine-tune (drops fp8, nvfp4, w4a16 and similar), revert chip
borders so filled chips stay visible, nudge the Run icon to center it,
and shrink the submenu chevron a touch.
* Inline chat rename and review-feedback fixes
Rename a chat inline as a rounded pill on the row instead of opening a
dialog. Enter saves, Escape cancels, clicking away saves. Projects and
training runs keep the existing dialog.
Address review feedback:
- Route the no-confirm chat delete through the shared cleanup helper so
it gets the same error toast and pin removal as the confirmed path.
- Archived chats now confirm before deleting (respecting the setting)
and pass the active thread, so deleting the open chat resets to a new
chat instead of leaving a stale thread URL.
- Only offer the MLX format filter on Discover, since downloaded
inventory rows are never tagged mlx and would filter to empty.
- Tighten the non-finetunable name match so a dot-delimited token such
as .tflite is also excluded from the Fine-tune ready channel.
* Sidebar: borderless inline rename, no name flash, align titles
Rename now edits the title as plain highlighted text with no pill or
box. While the debounced sidebar refresh catches up after a rename the
row shows the new name optimistically, so the old name no longer flashes
back in. Recent chat titles now line up flush under the Recents label.
* Profile: preferred name and avatar shape options
Add a "What should Unsloth call you?" preferred name that drives the
new-chat greeting, falling back to the first name then the login id.
Add a toggle to show the avatar as a full circle or a rounded
rectangle, applied everywhere the avatar appears.
* Settings: show version block at the top of General
Surface the Unsloth and package versions at the top of General, not
just in About. Both tabs share one StudioVersionSection so the version
fetch and markup live in a single place.
* Profile: pick a sloth sticker as your avatar
Add a curated set of sloth stickers users can choose as a profile
picture, shown below the picture shape toggle in Settings > Profile.
- Only squarish, low-whitespace stickers are listed so each one fills
the avatar frame cleanly.
- Selecting one reuses the existing avatar persistence (localStorage),
so it sits alongside the photo upload with no backend changes.
- Image avatars now get a neutral background so transparent stickers
read cleanly in both shapes.
* Profile: keep transparent avatars transparent
A transparent upload is now kept as WebP and shrunk to fit instead of
falling back to JPEG, which has no alpha and was painting a background
behind the image. The image avatar is also explicitly transparent.
* Profile: fall back to PNG for transparent avatars on Safari
Safari cannot encode WebP via canvas, so a transparent upload was
throwing instead of saving. Fall back to PNG, which keeps alpha and
works in every browser, before giving up. Still never uses JPEG.
* Archived chats: reset nav when deleting the open compare too
Compare panes do not write the active thread to the store, so the pair
id only lives in the route search. Derive the open chat id from the
route (thread or compare) like the sidebar does, so deleting the open
archived compare resets to a new chat instead of a dead URL.
* Profile: trim three sloth stickers from the picker
Drop the duplicate computer sloth without text on the screen (keeping
the Local one), the nature-screen sloth, and the gift sloth.
* Chat: tighten model selector right padding
Use less right padding than left so the trailing chevron does not leave
a heavy gap on the right of the trigger.
* Address review feedback on profile, reset and rename
- Give each sloth avatar button an accessible name so screen readers
can tell the options apart.
- Reset all local preferences now clears the delete-confirmation pref,
so it returns to the safe confirm default.
- A no-op Enter in inline rename now closes the editor instead of
leaving the row stuck as an input with its blur suppressed.
* Chat: rebalance model selector padding and chevron
More left padding than right and pull the chevron close to the label so
the trigger reads balanced around the text instead of heavy on the right.
* Hub: shrink the external link dialog icon
Set the icon to size-6 so it sits proportionally in the media circle
instead of filling it.
* Hub: shrink the external link dialog media circle
Override the media circle to size-12 with a size-5 icon on this dialog
only, so it is more compact without changing the shared component.
Polishes the in-app update notification banners and the sidebar account menu.
Update banners (web and llama.cpp):
- Add a download icon next to the title, aligned with the title text.
- Even out the action row so the buttons share balanced padding and equal spacing.
- Let the row wrap on narrow viewports so Copy command is never clipped under overflow-hidden.
Sidebar:
- Use the setting-07 cog for the profile button and the Settings menu item.
- Use the sun-03 icon for the Light Mode menu item.
- Slightly enlarge the profile cog.
Frontend only. Build and typecheck pass.

DiffusionGemma serves via the visual runner, which streams per-step
canvas frames so the answer resolves live in the bubble. The agentic
tool loop (generate_chat_completion_with_tools) does not forward those
frames, so whenever a tool pill (Search/Code) was on the live canvas
silently vanished while text still streamed. DiffusionGemma is not a
tool-calling target anyway, so report supports_tools=False for it: the
chat always takes the frame-forwarding path, and the Search/Code pills
disable themselves (a local model has no builtin web search either).
Also turn the artifacts canvas on by default for DiffusionGemma so a
full-HTML answer (e.g. a playable game) renders as an interactive
sandboxed card without the user flipping the global artifacts toggle.
* Studio: use a clearer check mark for the app-wide tick
Route every check mark through a shared tick-icon module with a plain
tick geometry, sized slightly larger than the stock icon so it reads
clearly in menus. No Pro icon assets are vendored.
* Studio: even out plus-menu hover padding on all sides
Trim the plus-menu side gutter to 9px so it matches the 0.5rem top/bottom
padding, and drop the container radius to 21px to keep corners concentric.
* Studio: bake the tick fallback stroke at 1.5 to match the icon set
