* Studio: decide diffusion routing before the SWA resolver
Loading a DiffusionGemma GGUF could fail with "llama-server failed to start. Check that the GGUF file is valid" while llama-diffusion-cli ran the same model fine.
_read_gguf_metadata set self._is_diffusion after calling _resolve_swa_pattern, both inside one try/except. The resolver reaches into transformers/HF, which can raise for an architecture transformers does not know (diffusion-gemma); the shared except then swallowed it and left _is_diffusion False, so the model was routed to plain llama-server instead of the diffusion runner. It only reproduced where the SWA pattern was not already cached/inline.
Set _is_diffusion right after the KV parse loop (before the resolver) so a resolver error can no longer drop the routing, and skip the resolver for diffusion models, which do not use Studio's SWA pattern.

UNSLOTH_STUDIO_LLAMA_ONLY=1, the llama.cpp-only fast path used by 'unsloth studio update', skipped the base-install block where STUDIO_HOME, _STUDIO_HOME_IS_CUSTOM, _STUDIO_OWNED_MARKER and _assert_studio_owned_or_absent are defined. setup.sh runs under 'set -euo pipefail', so the llama.cpp section aborted with '_STUDIO_HOME_IS_CUSTOM: unbound variable' before installing anything.
Hoist the studio-home and ownership resolution above the llama-only guard so both paths share it. Full installs are unchanged: the values are computed earlier but identically.
The update banner is driven by update_available from
/api/llama/update-status. Prebuilt (marker) installs decide this via
freshness.is_behind, which is mix-aware: a release at the same upstream
base build but with a new -mix-<sha> suffix counts as behind.
Source-build installs went through _source_build_status, which compared
only the numeric base build (installed_build < latest_build). When a new
prebuilt shared the installed upstream base (our usual mix re-tag at the
same base), it returned update_available=False and the banner never
showed. This is the common macOS case, where a failed prebuilt fetch
falls back to a source build that lacks the mix patches.
Make the source-build path mix-aware to match the marker path: same base
plus a -mix-<sha> tag now offers the update (and displays the mix tag),
a bare same-base rebuild does not, and the downgrade guard and unknown
-version fallback are unchanged.
* Studio: derive training output dir from model basename for local-drive models
A LoRA/QLoRA run started from a model loaded by absolute path (common when
models live on a non-system drive, e.g. G:\modelsAI\...\gemma-4-12B-it) seeded
the default output dir with that full path. resolve_output_dir then raised
"path escapes root ... is not under the studio outputs folder", so training
could not start from a model stored off the system drive.
Add default_run_dir_name(): Hugging Face repo ids keep their namespace
(org/model becomes org_model), while local paths collapse to their final
component so an absolute source path can no longer leak into the output dir.
Use it at the three worker derivation sites and add a regression test.

* Studio: cap run dir name length and drop redundant resolve
Apply PR review feedback: length-cap the auto-generated output dir component so an unusually long model name stays under the filesystem name limit, and drop the redundant double resolve_output_dir at the embedding site so all three derivation sites match.

The generated install command builds unsloth from git with
--no-build-isolation, so pip uses the environment's existing setuptools
rather than the pinned build-system requirement. On setuptools < 77 the
PEP 639 license string in pyproject.toml fails to validate and the
install aborts. Upgrade setuptools and wheel up front so the source
build always has PEP 639 support.
* 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.
* Installer: drop redundant -WindowStyle Hidden from the Windows launcher VBS
The desktop / Start Menu shortcut launches Studio through a generated
launch-studio.vbs that runs:
shell.Run "powershell ... -WindowStyle Hidden -File launch-studio.ps1", 0, False
The second argument to shell.Run is intWindowStyle 0 (hidden), so WScript
already launches the child windowless. The child -WindowStyle Hidden is
therefore redundant: dropping it keeps the launcher hidden and behaviour
identical, while removing the WScript-spawns-hidden-ExecutionPolicy-Bypass
PowerShell token combination that antivirus heuristics weight. That shape was
reported as a Kaspersky HEUR:Trojan.VBS.Agent false positive during install.
Adds tests/studio/install/test_launch_studio_launcher.py to stop the flag from
being reintroduced and to assert the launcher stays windowless via
shell.Run(cmd, 0, False).

* Fix llama.cpp prebuilt: skip the already-installed same-release fallback
install_prebuilt computes diffusion_visual_server_backfill_needed from the
newest candidate (plan.attempts[0]); when that is True it passed
existing_install_dir=None to validate_prebuilt_attempts, which disabled the
"existing install already matches this candidate" skip for the WHOLE plan. So
when the newest bundle failed validation the installer re-downloaded and
re-extracted an older fallback bundle that was already correctly installed.
Pass the real install dir always and gate the skip per-attempt: a matching
candidate is skipped unless that specific candidate still needs the
DiffusionGemma backfill re-extract.
Also make test_llama_cpp_search_roots_handles_studio_root_oserror read the full
_find_llama_server_binary / _kill_orphaned_servers method bodies instead of a
fixed 4000-char window. The except handler it asserts already exists, but the
function grew past the window so the guard silently failed; slicing to the next
sibling def keeps the check correct as the file grows.

* Studio: keep llama-server discovery from crashing on an access-denied candidate
_find_llama_server_binary probed candidates with Path.is_file(), which raises
PermissionError (WinError 5) when a path exists but is momentarily inaccessible
(antivirus lock, an install replace in flight, an elevated-install ACL),
aborting model validation. Treat a denied-but-present path as the real binary
so discovery returns it; absent paths still skip.
* Retry a transiently locked binary instead of returning a denied path
Returning a still-denied path only moved the PermissionError to the next
is_file() (probe_server_capabilities). Retry briefly so a transient lock
clears and discovery returns an accessible path; on a persistent lock return
nothing rather than a path downstream cannot stat.
* Studio: do not fall back to another llama-server when a pinned one is locked
A denied LLAMA_SERVER_PATH made discovery skip the explicit pin and run a
lower-priority managed or PATH binary, so a load could silently use a stale or
incompatible server. Split the probe into a file/absent/denied status: when the
pinned path exists but stays access-denied, warn and stop rather than falling
back to a different executable.
* Studio: never downgrade past a denied pinned or managed llama-server
Extend the no-fallback rule beyond LLAMA_SERVER_PATH: a present-but-denied
UNSLOTH_LLAMA_CPP_PATH or managed ($STUDIO_HOME/llama.cpp, ~/.unsloth/llama.cpp)
binary now reports temporarily-unavailable instead of silently launching a
lower-priority legacy or PATH server. Shared _scan_pinned/_unavailable helpers;
legacy in-tree and PATH stay genuine fallbacks (a denied candidate there just
continues).
* Studio: let diffusion asset lookup use a locked llama-server path for its dir
DiffusionGemma does not run llama-server; _find_diffusion_assets only needs the
install dir to find the adjacent llama-diffusion-gemma-visual-server. The
no-fallback rule returning None on a transiently locked llama-server therefore
hid an available visual-server and raised 'runner not found'. Add an
include_denied option so diffusion lookup gets the locked path (its dir is all
it needs), while inference keeps the no-denied-path, no-downgrade behavior.
* Studio: report a locked llama-server as temporarily unavailable, not missing
When the pinned/managed binary stays access-denied through the retries, discovery
returns None and load_model raised 'binary not found', a terminal error that
points users at reinstalling rather than retrying a transient AV/install lock.
Reuse include_denied to detect the locked path and raise a distinct
temporarily-unavailable, retry message instead.
* Studio: GGUF preflight treats a locked llama-server as present
The pre-download preflight (and so /api/inference/validate) used the default
discovery, which returns None for a transiently access-denied binary, so it
raised 'binary not found' for a binary that merely needs the lock to clear. Use
include_denied so the existence check counts a locked binary as present; the
load itself still reports a still-locked binary as temporarily unavailable.
* Studio: backfill the DiffusionGemma visual-server on a tag-matching update
An install made before the visual-server entered the copy allowlist (#6254)
matches on tag yet lacks the binary, so the update skip never backfills it and
DiffusionGemma fails with "runner not found". Re-extract the bundle when a
matching install is missing it, gated to the fork bundles that ship it so
upstream installs never thrash and so it self-limits once the binary lands.
* Studio: make the visual-server backfill bypass the existing-install short-circuit
The tag-matching skip is checked twice: once in install_prebuilt and again
inside validate_prebuilt_attempts via existing_install_matches_choice, which
only compares metadata and primary executables, not the DiffusionGemma
visual-server. So a stale install missing that binary still raised
ExistingInstallSatisfied and skipped the reinstall. Pass existing_install_dir
as None when a backfill is needed so the bundle actually re-extracts.
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.

The studio backend lazily imports unsloth_zoo submodules (export's
llama_cpp, hardware's vllm_utils, mlx, chat_templates). Each imports the
top-level unsloth_zoo, which raises 'Please install Unsloth via pip
install unsloth' unless UNSLOTH_IS_PRESENT is set (normally by import
unsloth). Only hardware.py set it per-site; the rest crash on a clean
install, and it surfaced on Windows. Set it once at backend startup (as
unsloth does on import) so every site, and the DiffusionGemma runner,
works across platforms. Follow-up to #6259 (which covered only the shim
subprocess env).
list_gguf_variants() keys files by _extract_quant_label(), which only captured the base quant token. Repos that ship the same base quant at multiple bits-per-weight (e.g. byteshape/Qwen3.6-35B-A3B-MTP-GGUF with three IQ4_XS files at 3.53/3.97/4.19 bpw) collapsed into a single row and Studio summed their sizes (~48 GB).
Extend the regex to capture an optional trailing -<N>(.<N>)?bpw modifier so each flavor produces a unique label. Round-trips through _find_local_gguf_by_variant and _download_gguf since both sides use the same extractor.
Fixes#5728.

A clean install could not run DiffusionGemma: the runner spawns
python -m unsloth_zoo.diffusion_studio.shim, and unsloth_zoo refuses to
import unless UNSLOTH_IS_PRESENT is set (normally by import unsloth). The
shim never imports unsloth, so the subprocess died with
'Please install Unsloth via pip install unsloth!' and the model load
failed with a 500. Set the flag in the runner child env, as unsloth does
on import.
When installed via 'curl -fsSL https://unsloth.ai/install.sh | sh', the
shell reads the script from the pipe on stdin. The optional 'start now'
step launches 'unsloth studio' in the foreground, and as a server it
inherits and drains the rest of the piped script from stdin. The shell
then hits EOF partway through the trailing if/case and dies with
'Syntax error: end of file unexpected (expecting fi)' (reported on WSL,
where /bin/sh is dash). Redirect the launch's stdin away from the pipe so
the script stays intact. The server does not read stdin and Ctrl+C still
works via the controlling terminal.

* Studio: account for mmproj VRAM in GGUF fit budget (#5825)
Vision GGUFs load the mmproj projector onto the GPU via --mmproj
alongside the weights, but the context auto-sizing / GPU-selection
budget sized off _get_gguf_size_bytes(model_path), which counts only
the weight file(s). The projector was never added, so the budget was
too optimistic: context got mis-estimated and tight vision loads
spilled to system RAM / OOM'd.
Resolve the launch projector once before GPU selection and fold its
size into the fit budget. The same resolved path feeds both the budget
and the --mmproj launch flag, so the two cannot disagree. The summary
log now reports the projector size separately, keeping "GGUF size"
accurate.
Adds _mmproj_vram_bytes() + unit tests (no GPU / network / subprocess).
* Studio: simplify mmproj summary-log concatenation (#5825)
Address review: the summary log mixed explicit `+` with implicit
f-string concatenation. Extract the optional projector fragment into
`mmproj_note` so the logger.info uses uniform implicit concatenation.
No behavioral change.

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

* Studio: make project sources work with RAG and polish project UI
Projects had a disabled Sources tab with an Add sources placeholder.
This wires it up end to end on top of the RAG engine:
- Add a project scope to the RAG store, ingestion and retrieval
- New endpoints: POST/GET /api/rag/projects/{id}/documents
- search_knowledge_base resolves kb, project and thread scopes; an
explicit KB stays exclusive, project and thread scopes combine
- Multi-scope search: FTS uses scope IN (...), vec0 KNN runs per
scope and merges by cosine score
- Lazy ALTER TABLE adds documents.project_id on existing databases
- Deleting a project also removes its indexed sources
- Sources tab now uploads with progress chips and drag and drop
- Chats inside a project auto-enable retrieval over project sources
when the project has indexed documents (cached probe, no Docs pill
needed); external providers still never receive rag_scope
UI polish:
- Rounder project cards with folder icon chip and softer shadow
- Project header icon in a rounded chip
- Chats/Sources pills and Add sources button without borders

* Studio: keep project card menu button visible while its menu is open
* Studio: drop focus outlines and rings on buttons and clickable icons, keep input focus styles
* Studio: address review feedback on project sources
- Remove uploaded files from disk when a project is deleted, confined

- 404 project uploads when the project does not exist, matching the KB
endpoint
- Guard lexical search against an empty scope list

settle so a chat sent mid-upload cannot cache a stale negative
- Keep keyboard focus rings: only mouse focus drops the Tailwind ring,
the browser default outline stays removed

The prebuilt bundles ship llama-diffusion-gemma-visual-server, but
runtime_patterns_for_choice pruned it, so a fresh install never placed
it next to llama-server. ensure_diffusion_visual_server then found no
standalone release asset and skipped it, leaving Studio unable to serve

* feat(studio): add S3 dataset configuration foundation (#4539)
Add foundational types and configuration for S3 bucket dataset loading:
- Add S3Config type to frontend training types
- Add S3Config Pydantic model to backend training models
- Add "s3" as a DatasetSource option
- Add s3Config state and setS3Config action to training config store
- Add i18n translations for S3 configuration (English and Chinese)
This provides the type definitions and UI text for S3 integration.
Full implementation requires boto3 dependency and data loading logic.
Refs: #4539
* [pre-commit.ci] auto fixes from pre-commit.com hooks

* Wire S3 config into training pipeline and prevent secrets persistence
- Pass s3_config from request into training_kwargs so it flows to training subprocess
- Add s3Config to NON_PERSISTED_STATE_KEYS to prevent AWS secrets from being
saved to localStorage
Addresses code review feedback on PR #5951.
* Exclude S3 config from database persistence to protect secrets
Filter out s3_config (which contains secret_access_key) from the
config_json stored in training_runs table, preventing AWS credentials
from being persisted to disk.

* Re-raise HTTPException in start_training and defer s3 DatasetSource widening for PR #5951
* Redact s3_config from W&B run config and accept camelCase S3 credential aliases for PR #5951
* feat(studio): implement S3 dataset loading end-to-end
Builds the actual S3 loader on top of the hardened #5951 foundation,
turning the 501-gated scaffold into a working dataset source.
Backend:
- Add core/training/s3_dataset.py: lists and downloads supported dataset
files (parquet/json/jsonl/csv) from an S3 bucket to a temp dir, using
IAM-role or access-key credentials. boto3 is imported lazily (optional dep).
- Wire s3_config into UnslothTrainer.load_and_format_dataset (downloads then
reuses the existing local-file path) and thread it through worker.py.
- Replace the 501 "not implemented" gate with a boto3-availability guard so
S3 works when boto3 is present and fails clearly when it is not.
- Add boto3 to studio.txt requirements.
- Add tests/test_s3_dataset.py (8 tests) covering download/filtering,
collisions, missing-boto3, and S3Config camelCase/IAM validation.
Frontend:
- Widen DatasetSource to include "s3"; add s3_config to the training payload
type and mapper; add an S3 validation branch and selectS3Source store action.
- Add s3-config-form.tsx (bucket/region/prefix/keys/IAM toggle) reusing the
existing studio.dataset.s3.* i18n strings.
- Add a Hugging Face / Local / Amazon S3 source toggle in dataset-section;
the S3 config card replaces the dataset combobox when S3 is selected.
- Fix DatasetPreviewDialog to accept the widened DatasetSource type.

* Studio: override chat template for unsloth/gemma-4-*-GGUF with bundled gemma-4.jinja
The chat templates baked into the shipped unsloth/gemma-4-*-GGUF quants predate
Google's gemma-4 chat-template PR #118 and lack the preserve_thinking flag, so
Studio cannot surface the "Preserve thinking" toggle for Gemma 4. Bundle the updated
template and override the embedded one at llama-server launch via --chat-template-file,
scoped to the gemma-4 GGUF family, so users do not need to re-download any quant.
- Add studio/backend/assets/chat_templates/gemma-4.jinja (PR #118 based;
preserve_thinking defaults false, the one deliberate divergence from upstream).
- Add core/inference/chat_templates.py: gemma-4 GGUF matcher plus an
effective-override resolver (explicit user template still wins).
- Wire the resolver into routes/inference.py ahead of the reload-dedup check and
both load_model calls so the live backend and the incoming request compare against
the same template text (no spurious reloads).
- Default preserve_thinking off in the launch-time chat_template_kwargs so direct
API callers match the UI default.
- Ship the asset via package-data and add unit tests.
* Studio: ship E2B/E4B edge variant of the bundled Gemma 4 template
Google ships two distinct gemma-4 chat templates: E2B and E4B omit the empty
"<|channel>thought<channel|>" block on enable_thinking=false, while the
12b/26B-A4B/31B family emits it (confirmed against google/gemma-4-E2B-it,
-E4B-it, -12b-it, -26B-A4B-it, -31B-it; the two families differ only in that
one block). The single PR #118 based template followed the larger-model
behavior, which is wrong for the E2B/E4B GGUFs this feature most targets.
- Add studio/backend/assets/chat_templates/gemma-4-edge.jinja: identical to
gemma-4.jinja minus the empty-thought-block, matching E2B/E4B behavior.
- Route unsloth/gemma-4-E2B-it-GGUF and -E4B-it-GGUF to the edge template;
12b/26B-A4B/31B keep gemma-4.jinja.
- Extend tests for the edge matcher, per-family routing, and the empty-thought
block difference (off for edge, on for standard).
* Studio: address review feedback on the gemma-4 template override
- Normalize owner-less shorthand model ids in the template matcher: a bare
"gemma-4-E2B-it-GGUF" is canonicalized to "unsloth/" the same way
ModelConfig.from_identifier does, so shorthand loads still get the override
(and the preserve_thinking capability) instead of falling back to the
embedded template.
- Scope the test's module stubs with unittest.mock.patch.dict instead of
sys.modules.setdefault, and only stub deps that are missing, so the global
module registry is not polluted for tests that run afterwards.
- Guard the Jinja render tests with pytest.importorskip("jinja2") so the suite
stays runnable in minimal Studio environments where jinja2 is not present.
- Add tests for shorthand resolution.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: address 10-reviewer P1 findings on the gemma-4 template override
- /status no longer surfaces Studio's auto-applied bundled template as a
user-authored chat_template_override. The frontend adopts that field as
editable state and would otherwise re-send the gemma-4 template as an explicit
override for a later, unrelated model. /status now reports None when the live
override equals the model's auto-resolved bundled template.
- When a bundled family template is in effect, strip an inherited
--chat-template-file from llama_extra_args too (not only when the raw request
set chat_template_override). Otherwise a stale inherited template, appended
last, shadows the bundled one while Studio reports the bundled template's
capabilities.
- Write the temp chat-template file as UTF-8 explicitly, and keep the bundled
templates ASCII (replaced em dashes), so non-UTF-8 Windows locales cannot raise
UnicodeEncodeError or emit a mis-encoded template. Added an ASCII guard test.

* Studio: refine menu chevron, tick icon, and one-line plus-menu shape
- Shrink submenu > chevron to size-3.5 in the dropdown, context, and
menubar sub-triggers so it stays centered but reads lighter.
- Use the tick-02 duotone-standard geometry for the app-wide check mark
via a shared tick-icon module.
- Drop the fully rounded pill on one-line plus-menus so they match the
standard menu shape.
* Studio: nudge submenu chevron down to 13px
* Studio: nudge submenu chevron down to 12px
* Studio: drop vendored Pro tick geometry, keep free check icon
The tick-02 duotone-standard path is a Hugeicons Pro asset and is not part
of the MIT free pack, so vendoring it into the source is a licensing risk.
Revert the check mark to the bundled free Tick02Icon and remove the shared
tick-icon module. Keeps the chevron sizing and one-line plus-menu changes.

* new-chat shortcut, composer draft autosave, archive threads
* fix
* Studio: harden chat UX additions for legacy threads and unavailable storage
Two robustness fixes on top of the new chat UX features:
- groupThreads: coerce archived to a boolean before comparing
(Boolean(t.archived) !== archived). Threads from the older browser-only
Studio, or any record predating the archived field, can carry
archived === undefined/null. The raw `!== archived` comparison dropped
those from BOTH the Recents and Archived sidebar groups, hiding existing
chats. Treat missing as not-archived so legacy chats still appear in
Recents.
- composer draft autosave: wrap the localStorage read and write in
try/catch. When storage is unavailable (private mode, disabled cookies,
blocked storage) or full (quota exceeded), getItem/setItem throw; the
throw in the restore effect would surface to React and break the chat
page. Draft persistence is best-effort, so degrade quietly.
Verified with bun unit tests on the real groupThreads (legacy undefined no
longer vanishes) and Playwright across chromium, firefox and webkit (draft
save/restore/isolation/clear, new-chat shortcut + crypto.randomUUID, and
localStorage blocked/quota throw handling). tsc clean; no new eslint findings.
* Fix composer draft bleed and orphan cleanup for PR #5771
Centralize composer draft storage in a small util and tighten two edge cases:
- New chat draft bleed: every new chat shared the chat-draft:__new__ slot, so
starting a fresh chat could restore the previous one's half-typed text. Clear
that slot at every new chat entry point (sidebar buttons and Cmd/Ctrl+Shift+O).
- Orphan drafts: deleting a thread left its chat-draft:<id> key behind. Clear
the draft for every deleted thread id.
New util utils/composer-draft.ts owns the key format and wraps localStorage in
try/catch (private mode, blocked storage, quota), replacing the inline copy in
thread.tsx so reads and writes stay best effort everywhere.
* address review
* fix: remove unused chat sidebar binding

* Studio: fix Downloaded model list disappearing and order it by last download
The chat model picker scan for cached GGUF and safetensors models aborted
whenever an auxiliary Hugging Face cache dir (such as ~/.cache/huggingface/hub)
was unreadable, returning an empty list. That hid the Downloaded section and
let already downloaded models appear under Recommended. Isolate each cache
probe so an inaccessible directory is skipped instead of failing the scan.
Also order Downloaded newest-first using cached blob mtimes (multi-quant repos
group by their most recent quant), keep the section visible while searching,
and make the per-quant downloaded check per-snapshot and mmproj aware so a
Recommended quant is never falsely marked downloaded.

* Studio: harden gguf-variants scan and dedupe by newest timestamp
Guard f.stat() per file so a broken symlink or unreadable file in a
snapshot no longer aborts the downloaded check early, and match quant
labels case-insensitively. When the same repo is present in multiple
caches with equal size, keep the newest last_modified so Downloaded
ordering reflects the most recent copy.

* Studio: apply cache-scan guards to sibling endpoints found in review
Extend the inaccessible-cache guard and mmproj/stat hardening to the
parallel HF cache code paths flagged in review:
- list_local_models and the Hub inventory scan now skip an unreadable
auxiliary cache instead of returning 500.
- The GGUF download-progress endpoint excludes mmproj adapters and
guards f.stat() so one bad file does not zero a repo's progress.
- The offline snapshot scanner guards its is_dir() probes.
- The chat-only picker no longer renders a blank list when a search
matches only cached non-GGUF models.

Swaps the arbitrary px-[10px] on the Hub option menu surface for the
standard px-2.5 utility. Both resolve to 10px, so this is a no-op
visually and just keeps to the standard spacing scale.
Rounds out the Hub chrome and aligns a handful of icons with the rest
of the app. The header stat pills, HTTP/Xet toggle, HF token button,
info chips, status badges and the single-row download card are now full
pills, and the All formats style dropdown matches the composer + menu
geometry. Also widens the chat options menu so "Move to project" fits
on one line, and swaps a few icons to their HugeIcons equivalents.
Changes:
- hub.css: hub-tag-soft/hub-tag-meta pills go fully rounded; a single-
row hub-download-card reads as a full pill via :has(), while the
expanded card keeps its 22px radius, border and background.
- hub-option-menu.tsx: dropdown surface and items match the composer
+ menu (22px container, 10px side padding, 12px item radius).
- hf-token-indicator.tsx, transport-toggle.tsx: fully rounded with a
fixed 26px height so they line up with the neighbouring pills.
- model-inspector.tsx, dot-tag.tsx, gguf-download-card.tsx: status and
info chips go fully rounded.
- models-header.tsx: Eject uses RemoveCircleIcon; active model pill
fully rounded.
- on-device-folders-dialog.tsx: folder rows use Folder02Icon.
- pickers.tsx: Recommended star uses the HugeIcons star.
- command.tsx, chat-search-dialog.tsx, prompt-storage-dialog.tsx: search
fields use the HugeIcons Search01Icon.
- app-sidebar.tsx: chat options menu widened to w-56.
Pure styling and icon swaps, no behavior changes.
* install.sh: persist ROCm-on-WSL drop-in even when rocminfo already works
_maybe_bootstrap_rocm_wsl calls _ensure_rocm_probe_env (which exports a
transient HSA_ENABLE_DXG_DETECTION + adds /opt/rocm/bin to PATH on the
installer process) right before the "rocminfo enumerates gfx1151 -> already
set up, return early" gate. On any reinstall over an existing /opt/rocm --
the common case, since the uninstaller keeps shared ROCm userspace but
removes /etc/profile.d/unsloth-rocm-wsl.sh -- that probe env makes rocminfo
succeed, so the gate returns 0 WITHOUT ever persisting the drop-in. The
transient env dies with the installer, so the next login shell (Studio,
llama-server) sees no GPU: torch cuda_avail=False, rocminfo finds nothing,
the llama.cpp ROCm prebuilt segfaults on a GPU it can't reach.
Factor the drop-in writer into _persist_rocm_wsl_dropin() and call it before
the early return so the persistent env is restored whenever librocdxg is
present. Idempotent (only writes when the drop-in is missing), gated on
librocdxg so it never fires on non-WSL/non-ROCDXG hosts, root-writes or
sudo-tees like before. The fast-path branch now reuses the same helper.
Reproduced on gfx1151 (Radeon 8060S) under dash (the curl|sh shell):
before the fix a reinstall left the drop-in absent and torch cuda_avail
False; after, the drop-in is persisted and a fresh login shell reports
cuda_avail True. Verified under both dash and bash, and idempotent on
re-run.
* Studio WSL: load system HIP before a prebuilt's bundled runtime (gfx1151)
The lemonade / published llama.cpp ROCm prebuilts bundle their own HIP
runtime (libamdhip64) built for bare-metal Linux. In WSL the GPU is reached
through the system ROCm's librocdxg bridge over /dev/dxg, which the bundled
runtime cannot drive -- it segfaults on the first GPU call. So:
- install_llama_prebuilt.py: the prebuilt's llama-quantize/llama-server
validation runs with the bundle dir first on LD_LIBRARY_PATH, segfaults
(empty stderr), and the install silently falls back to a CPU source build
(which on this host can't even build for GPU -- hipcc absent). The Strix
Halo WSL user ends up on CPU despite a working GPU.
- llama_cpp.py: even if a GPU prebuilt were kept, the serve-time launcher
put the bundle dir first too, so it would crash at load.
Fix: on a ROCDXG WSL host (gated on /dev/dxg + "microsoft" /proc/version +
a librocdxg-providing /opt/rocm), prepend the system ROCm lib dir to
LD_LIBRARY_PATH so the WSL-capable libamdhip64 + librocdxg load first, while
the bundle still supplies libggml-hip / librocblas with the gfx1151 kernels.
Set HSA_ENABLE_DXG_DETECTION=1 alongside. Added _wsl_system_rocm_lib_dirs()
to both modules (kept identical so a prebuilt that passed install validation
runs the same way at serve time). Strict no-op on bare-metal Linux, NVIDIA,
macOS, and Windows.
Verified on gfx1151 (Radeon 8060S) in WSL (ROCm 7.2.1 + librocdxg, Adrenalin
ROCDXG): before, the lemonade gfx1151 prebuilt segfaulted and the install
fell back to a broken CPU build; after, install_llama_prebuilt validates and
keeps the GPU prebuilt (source=published, prebuilt_fallback_used=False), and
Studio serves Qwen3-1.7B-GGUF at 53 tok/s with the model resident in GPU
memory (llama-server device_info: ROCm0 = AMD Radeon 8060S).
* tests: cover the WSL ROCDXG drop-in + system-HIP-ordering fixes
- _wsl_system_rocm_lib_dirs: no-op without /dev/dxg, on bare-metal Linux,
and on WSL without librocdxg; returns the system lib dir on a ROCDXG WSL
host.
- binary_env: prepends the system ROCm lib dir ahead of the bundle and sets
HSA_ENABLE_DXG_DETECTION on WSL; unchanged on bare-metal Linux.
- install.sh: _persist_rocm_wsl_dropin exists, is gated on librocdxg, and the
rocminfo-already-works early return calls it before returning.
- llama_cpp.py: the serve-time launcher prepends the WSL rocm dirs before the
bundle dir (mirrors binary_env).
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Tighten WSL ROCDXG fix comments (no logic change)
Condense the drop-in / system-HIP-ordering comments and docstrings added in
this PR. Verified comment-only via AST parse + py_compile + sh/bash -n, the
308-test rocm_support suite, and a dash functional re-run of the bootstrap
(drop-in still persisted, env still set).

* fix(studio/responses): forward chat_template_kwargs enable_thinking to chat request
The /v1/responses translation in _build_chat_request dropped
chat_template_kwargs (e.g. {"enable_thinking": true}) sent via the
Responses extra-body, so reasoning control was silently ignored.
Lift enable_thinking onto the typed ChatCompletionRequest field,
mirroring openai_chat_completions, so both the non-streaming and
streaming Responses pass-through paths honor it.

Web "New Unsloth version" banner now matches the llama.cpp banner design
(borderless rounded card, drop shadow, heading title) and moves to the
bottom-right, stacked with the llama.cpp banner in a shared container. Keeps
the Release notes link, and the copy command is platform aware (curl for
macOS/Linux/WSL, irm for Windows).
The web banner is checked once per launch only, with no polling; a re-check
just happens the next time the user opens the app. Copying the install
command no longer dismisses it for good: it hides and returns on the next
launch while the install is still behind. The X button still dismisses the
version permanently.
llama.cpp progress bar: poll the job every 500ms and smooth the displayed
value so it animates with the real download instead of snapping to the ~90%
post-download hold and finishing.
