* Replace standalone Studio wording with Unsloth
Replace the single word Studio with Unsloth wherever it is used as
shorthand for Unsloth Studio in docs, CLI output, UI strings, i18n
locales, workflow display names, comments and docstrings.
Kept unchanged: the full name Unsloth Studio, third party product
names (LM Studio, Visual Studio, Mac Studio), feature names
(Recipe Studio, Fine-tuning Studio and its translations), and all
identifiers such as env vars, commands, paths and filenames.
* Address review feedback on the Studio wording rename
Use "an" before Unsloth where the rename left the article as "a".
Restore the split brand where Unsloth and Studio render as two halves
of the full product name: the onboarding sidebar subtitle and the
IPv6 localhost warning. Scope two messages to the full name Unsloth
Studio where plain Unsloth was misleading: the AMD README bullet and
the CLI studio setup error.
* Studio: exclude /api/export/status from request access logs
The frontend polls /api/export/status every 5s to detect export start, so it
fires continuously even when idle. Each poll emitted an info request_completed
access line, making up most of the server access logs. Add it to _EXCLUDED_PATHS
alongside /api/train/status. The endpoint is unchanged; export state is still
logged by the export modules and streamed over SSE, so no signal is lost.
* Studio: collapse hub download-progress polls in the access log
download-status and gguf-download-progress (plus the dataset equivalents)
are polled about twice a second for the whole download, so each emitted an
info request_completed line. Add them to _QUIET_POLL_PATHS so they collapse
to one heartbeat line per 10s instead of one per poll.
* Studio: log hub download progress at 10% steps
The access log carried no real progress, only poll pings. Emit one
hub_download_progress line per 10% step from the shared snapshot progress
reader, so an active download shows actual percentage without a line per
poll. Throttled per job and resynced if the same download restarts.

for more information, see https://pre-commit.ci
* Studio: drop successful chat thread/project CRUD from the access log
A single chat turn fans out about twenty requests under /api/chat/threads
and /api/chat/projects (list, fetch, per-message forks, and the message
writes) that only reflect the UI re-rendering. Suppress their 2xx access
line so the log keeps the signal (generation, tool calls, code execution,
engine stats) and errors. Non-2xx on these paths still log.
* Studio: silence transformers torch_dtype deprecation warning
transformers logs "`torch_dtype` is deprecated! Use `dtype` instead!" once at
model-config load via logger.warning_once (logging, not warnings), so a warnings
filter cannot catch it. Attach a small logging.Filter in setup_logging, which
runs before any model config is parsed, to drop that record on the transformers
loggers that emit it.
* Studio: quiet inference load-progress polls and log throttled load progress
The frontend polls /api/inference/load-progress about twice a second for the
whole model load, so each emitted a request_completed line. Add it to
_QUIET_POLL_PATHS (heartbeat) and emit one inference_load_progress line per 10%
step from the load-progress route, so a load shows real percentage instead of a
line per poll.
* Studio: fully suppress download/load progress poll access lines
The download-status, download-progress, gguf-download-progress, active-downloads
and transport-status polls (model and dataset), plus inference load-progress,
fire ~2x/s for the whole download or load. Their progress is now reported by the
hub_download_progress / inference_load_progress events (and the viewer's progress
line), so the per-poll access line adds nothing. Drop it on 2xx and keep it on
errors, instead of the prior 10s heartbeat. Chat CRUD suppression is folded into
the same _is_quiet_success helper.
* Studio: suppress training-tab model/dataset download-progress polls
The training tab polls /api/models/download-progress and
/api/datasets/download-progress about twice a second for the whole prep phase.
These are separate routes from the /api/hub equivalents and only scan the cache,
so their 2xx access line adds nothing (on Windows they always read 0 since the
bytes live in snapshots/, not blobs/). Suppress the 2xx line and keep errors,
alongside /api/models/gguf-download-progress.
* Studio: drop transient pre-auth 401 on chat thread/project polls
On first load the SPA fires chat thread/project GETs before the initial token
refresh, so they 401 until /api/auth/refresh runs and the retries succeed. That
pre-auth 401 is a bootstrap artifact, not an error; suppress it alongside the
already-quiet 2xx line. Genuine 4xx/5xx on these paths, the download/load poll
401s, and all /api/auth/* still log.
* Studio: quiet tab-switch list polls and per-poll scan/reconnect logs
Switching between the Train, Export, and Chat tabs refetches list endpoints on a
timer, and each hit re-logs internal detail. Heartbeat /api/train/runs,
/api/models/checkpoints, /api/models/local and /api/rag/knowledge-bases (10s
window, first hit and errors still log), and downgrade two per-poll INFO lines to
debug: the checkpoints scan summary ("Found N training runs") and the
per-reconnect SSE resume line. The meaningful "replayed N missed steps" line,
logged only when steps were actually replayed, stays at info.
* Studio: enable tokenizer parallelism for dataset prep on Windows/macOS
TOKENIZERS_PARALLELISM was forced off everywhere to stop datasets' forked map()
workers from deadlocking, but that fork only happens on Linux. On spawn platforms
(Windows/macOS) dataset.map() runs in-process (dataset_map_num_proc returns None),
so disabling tokenizer parallelism leaves the fast tokenizer single-threaded and
dataset prep runs serially on one core. Keep it off on Linux (fork safety) and on
for spawn platforms, where there is no fork to deadlock. Measured ~7x faster
tokenization (12.5s -> 1.7s for 20k rows on a 32-core Windows box).

* Studio: log throttled training status to the server log
Training step/loss/epoch only went to the UI via SSE, so the server log showed
inference engine_stats and train/runs heartbeats but nothing about the actual
run. Emit one throttled training_progress line (step/total, percent, loss, epoch,
eta) from the CUDA event pump: the first step, then at most every 30s, plus the
final step, resyncing when a new run restarts the counter. Per-step UI streaming
is unchanged.
* Studio: quiet llama.cpp update-status polls and log throttled update progress
The prebuilt llama.cpp update polls /api/llama/update-status about twice a second
for the whole download and install. Suppress its 2xx access line (errors still
log) and emit one throttled llama_update_progress line per 10% step from the
status route, so the update shows progress without a line per poll. The existing
"llama update: installing" and "llama update: success" events still bracket it.
* Studio: quiet the export log-tail poll
The Export tab polls /api/export/logs about once a second to stream the export
subprocess output into the UI panel. Suppress its 2xx access line; the real
progress is already logged as event-driven "Export subprocess status: <phase>"
lines plus the subprocess start and checkpoint-loaded events, and errors still log.
* studio: keep errors and mutations visible in access-log suppression
Make the quiet-success access-log suppression GET-only so chat thread/project
mutations (POST/PUT/DELETE) still log; only their list-poll 2xx and the
transient pre-auth 401 are dropped.
Suppress /api/export/status 2xx only (move it out of the all-status exclude
set) so a 401/403/500 on it stays visible.
Legacy /api/models and /api/datasets download-progress polls emit no
hub_download_progress events, so heartbeat them via the 10s quiet-poll window
instead of suppressing outright, keeping download visibility (notably on
Linux). The event-emitting /api/hub download polls stay fully suppressed.
Update and extend the middleware tests to cover GET-only suppression, the
export-status error path, and the legacy download heartbeat.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* studio: tighten access-log and training-progress comments
Comment-only pass: collapse the multi-line explanations in the logging
middleware and the throttled training-progress logger to fewer lines while
keeping the rationale. No behavior change.
* studio: log structured export_progress phases
Emit a structured export_progress event per phase (consolidated in the server
log like training and download progress) instead of a plain status string, and
add a phase milestone at the start of the heavy export step so the
merge/save/convert is visible in the server log, not only in the forwarded
stdout panel.
* Studio: reset training-progress log throttle on each new run
start_training rebuilds the per-run progress state but left _last_progress_log_ts/_last_progress_log_step at their prior values. A run started within 30s of a previous one whose last logged step matched the new run's first step would hit the step == prev short-circuit and drop the promised first training_progress line, then stay suppressed until the old 30s window expired. Reset both fields when a new job is accepted.
* Studio: keep post-bootstrap chat 401s visible in the access log
The chat thread/project 401 suppression dropped every GET 401 on those prefixes, so a genuine expired-session 401 vanished alongside the transient pre-auth race. Gate the 401 drop on a per-middleware bootstrap latch that flips once /api/auth/refresh first succeeds: before that the 401s are the pre-refresh race and are suppressed; after it any chat 401 is a real failure and logs. Add a test for the post-refresh case.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: limit chat access-log suppression to the exact list polls
The chat thread/project suppression matched by startswith, so it also dropped the 2xx access line for detail and message reads (/threads/{id}, /threads/{id}/messages, /threads/{id}/messages/{id}, /projects/{id}) that are not the high-frequency list polls, losing their access and latency logging. Match the two list paths exactly instead, so only the intended list polls (and their pre-auth 401 race) are suppressed while detail and message reads keep their access line. Add a regression test.
* Studio: reset inference load-progress throttle for each load
The load-progress throttle (_last_load_progress_step) is a module global that persisted across loads, so a cached or small load whose first sampled /api/inference/load-progress response already reported fraction=1.0 hit step == prev (10) from a prior completed load and emitted no inference_load_progress line, while that endpoint's access log is suppressed, leaving the new load with no progress signal. Arm the throttle at load initiation in _load_model_impl so each load's first step always logs. Add a regression test.
* Studio: tighten logging comments
Collapse a few verbose comments (tokenizer-parallelism note, torch_dtype filter, legacy download-poll heartbeat, chat list-path suppression) to fewer lines without changing intent or code.

* address review
* Studio preview: pin adapter, guard streaming submit, robust copy-link
Harden the public per-checkpoint preview surface:
- Pin use_adapter=True in the preview payload sanitizer. Otherwise an
unauthenticated /p caller can POST use_adapter=false, which calls
disable_adapter_layers() on the shared in-memory model without restoring
it; since load_model skips reloads for the same checkpoint, every later
visitor (the page never sends the field) keeps getting base-model output
instead of the fine-tuned checkpoint. Forcing it on also re-enables a
previously disabled adapter and no-ops on merged checkpoints.
- Ignore preview-page submits while a response is streaming. The send
button was disabled but the Enter handler still called requestSubmit(),
so a second request could start before the first reply landed in msgs and
reorder the chat history. Both the keydown and submit handlers now honor
the disabled button.
- Keep the cloudflare-URL polling loop alive across transient startup fetch
errors instead of letting one rejection halt it.
- Build the copy-link from a backend preview_ref (output dir relative to
outputs_root, gated on previewability and the two-segment /p route limit)
so a nested output dir no longer copies a basename-only link that 404s.
Expose preview_ref on training run summaries.
Add route-level security tests (path traversal, payload sanitization,
asset containment, CSP header, HTML title escaping, streaming lock held
until drained) and preview_ref unit tests.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio preview: Safari-safe submit and adapter pin only for LoRA
Follow-ups from cross-browser and route simulations:
- Preview page: send the message from a shared send() helper called by both
the form submit and the Enter key, instead of form.requestSubmit(). The
latter throws on Safari < 16 and older iOS, which broke Enter-to-send there.
Verified across Chromium, Firefox and WebKit with Playwright.
- Only pin use_adapter=True when the resolved checkpoint is a LoRA adapter
(adapter_config.json present); for a merged checkpoint strip it to None.
A merged model has no adapter to toggle, so forcing it on only produced a
per-request "not a PeftModel" warning. The cross-request base-model
contamination fix still holds for LoRA previews.
Add a merged-checkpoint test asserting use_adapter is stripped to None.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio preview: trim verbose comments
Tighten comments across the preview routes, page, checkpoint helpers, and tests
to short single-line notes; drop ones that just restate the code. No behavior
change (verified comment/docstring-only with comment_tools.py check).
* Harden preview routes for PR #6486
- Return a generic 400 detail on a rejected preview path so the public /p
route never echoes the absolute install path (the real reason is logged
server-side instead).
- Strip confirm_tool_calls, session_id and rag_scope in the preview payload
sanitizer so the public surface stays inert regardless of the tool gate.
- Use Path.is_relative_to for the asset containment check, matching the rest
of the codebase.
- Add img-src 'self' and font-src 'self' to the preview page CSP.
- Preview page: on a mid-stream error keep the streamed text, flag the break,
and restore the prompt so the user can retry; drop the unused --font-sans var.
