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

* Space out subheadings and gate Other models on non-Unsloth downloads
* Use direction-right icon for Other models

* Widen Connected menu so dropdowns align with Search Hub
* Model selector: truncate long quant labels and tidy layout
- Hub GGUF card: truncate long file-path quant labels with an ellipsis
instead of overflowing the row.
- Connected layout: left-pack the dropdowns and size the box so the last
dropdown's right gap matches the pill's left gap, with Search Hub on its edge.
- On Device: show MLX/Safetensors with the size on non-GGUF rows.
- Connected list rows use the same grey hover as the tabs; the selected
section tab no longer shows a hover change.
* Model selector: drop stale custom section on restore
A persisted custom section value no longer maps to a tab, so restoring it
opened the picker to an empty view. Fall back to recommended instead.
* Model selector: align the non-connected search bar with the All dropdown
Nudge the non-connected box width so the search bar's right edge meets the
All dropdown, which lands Search Hub on the last dropdown's edge.
* Studio chat model selector: remember last tab, route non-GGUF downloads through Hub, stack overlays
- Restore the last Hub section (Recommended / On Device) on every open instead of always snapping to On Device when downloads exist.
- Route uncached non-GGUF repos (safetensors / MLX) through the Hub download manager via a snapshot download, so every model download shows in the bottom-right indicator and follows Load on selection like GGUF.
- Allow safetensors in Recommended on Mac (they run locally there now), and honor the Safetensors format filter instead of dropping it via the recommendation default.
- Stack bottom-right overlays in one column so the download panel and banners never overlap.
- Add evenly spaced divider lines between the On Device subheadings.
- Pad the bottom of the list so the floating Eject pill never covers the last row.
* Studio downloads panel: widen left padding on header and rows
Bump the left inset to pl-4 while keeping pr-3 so the collapse and cancel buttons stay put.
* Studio: update cached-gguf route tests for the has_vision field
list_cached_gguf now returns has_vision per row (vision badge on On Device);
the expected dicts were missing it. True for the mmproj vision repo, False elsewhere.
* Studio: keep MLX/safetensors selectable in chat-only Mac search
The empty Recommended view allows GGUF plus MLX/safetensors on Mac, but the
curated and HF search lists dropped non-GGUF in chat-only via a GGUF-only filter,
so typing a query hid runnable Mac models. Reuse isRecommendableFormat in both
lists so search matches the empty view (chat-only non-Mac stays GGUF-only).
* Model selector: restore global model search and fix GGUF/device-fit regressions
- Search: training, export and onboarding pickers searched only the unsloth org
on a typed query. Restore the prior behavior (global Hub search with unsloth
floated first when a query is typed, curated unsloth listing when empty).
- Recommended browse: the GGUF/MLX-only gate ran before the format filter, so
the Safetensors filter and the Trending/Recent sorts always came back empty.
Apply that gate only for the Recommended sort and chat-only mode.
- GGUF metadata: request the gguf expand field through listModels so repos with
no size token in the name (Kimi, MiniMax, GLM) report a param count for the
size and OOM badge.
- Local GGUF: custom-folder and standalone ./models/*.gguf files now load
directly with the GGUF marker instead of dead-ending in the variant expander,
and scanned GGUF folders are classified via a backend model_format hint.
- Device fit: use system RAM in the budget on unified-memory hosts, and keep MLX
rows selectable on chat-only Macs.
- kv-cache-estimate: resolve the quant from the snapshot-relative path, skip MTP
drafter files, and prefer the most complete snapshot (mirrors the variant
scanner). Bound the Ollama manifest walk.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Model selector: classify suffixless local GGUF folders consistently
Complete the model_format plumbing so a GGUF folder is detected and loaded
through the same GGUF path that the format filter already uses:
- _scan_models_dir: a config.json no longer disqualifies a folder whose only
weights are .gguf, so HF GGUF repos shipping a config still classify as GGUF.
- _scan_lmstudio_dir: emit model_format for every GGUF row (LM Studio dirs
rarely carry a -GGUF suffix), via a shared _dir_model_format helper.
- Custom Folders and LM Studio rows: use localModelIsGguf (the same helper the
filter uses) so the row label, expand-vs-direct-load, and isGguf flag agree;
a suffixless GGUF folder no longer filters as GGUF but loads as non-GGUF.
Adds tests/test_local_model_format.py covering the classification rule.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio model selector: tighten section spacing
Trim each subheading's gap to its rows (pb-1.5 to pb-1) and pull the On Device
heading block tight to the controls while Recommended keeps a little top room.
* Hub: format filter fix, sort defaults, avatar and layout polish
- Format dropdown now filters the feed's Latest list too, so the default
GGUF hides fp8/safetensors and picking a format changes the rows.
- Latest Unsloth Models sorts by newest created, not recently updated.
- Sort dropdown order: Newest, Trending, Most downloads, Recently
updated, Most likes.
- Unsloth uploads with no upstream provider logo show the Unsloth avatar
instead of a colored initial.
- Owner scope pill gets a little more room before the chevron.
- README detail column lines up with the top bar (both-edges gutter).
- Long file-path quant labels truncate instead of overflowing the row.
- Model list keyboard nav no longer clips the focus ring.
- Run settings sheet: restore the Remember settings toggle and larger
Load/Cancel buttons on the staged load flow.
* Hub: hide the RAG embedding model from browse previews
The Hub discover feed and chat model selector pull from the Hugging Face
listing on the client, which the backend _is_hidden_model filter never
touches, so the RAG embedder (unsloth/bge-small-en-v1.5-GGUF) and the
llama.cpp validation probe leaked into the lists.
Added isHiddenModelId mirroring the backend needles and filtered it out of
the discover rows, the trending feed, and the selector's recommended and
Hugging Face search lists. Per-repo file and download views are untouched,
so the model is never deleted and a reinstall still shows it as already
downloaded.
* Studio: skip hidden dirs when checking a folder for downloaded models
_dir_has_downloaded_model walked the tree with rglob("*") bounded by
max_entries. rglob yields entries in arbitrary order and counts every one, so a
model directory that also holds a large hidden subtree (.git/.cache/venv) could
exhaust the budget before reaching the real weights and falsely report no model,
hiding a valid Recommended-folder chip. Replace the generic-weights pass with a
bounded BFS that skips hidden directories so their entries can't starve the walk.
Adds a regression test (50-entry .git beside the weights, max_entries=10).
* Fix/adjust model selector handling for PR #6364
* Studio: address codex review on the staging/recommended-folder paths
- chat-page auto-load: selectModel only clears pendingSelection on success, so a
failed auto-load left the hidden stage (and its edited load knobs) behind.
Abandon the stage when it still matches the failed pick.
- model picker: count fine-tuned rows in the On Device empty check so a
fine-tuned-only tab no longer shows a false 'No models on device' message
above the Fine-tuned section.
- general settings: add the remembered per-model load settings key to PREFS_KEYS
so 'Reset all local preferences' actually clears it.
- recommended-folders: recognize PyTorch .bin weights (gated by the scanner's
weight-name prefixes) so a .bin-only model folder still earns a chip; add tests.
* Studio: name-gate .bin weight detection and complete selector preference reset
Follow-up to the codex review on the model_format/recommended-folder paths:
- _dir_model_format and _scan_models_dir treated any .bin (incl. tokenizer.bin)
as a non-GGUF weight, so a suffixless GGUF folder shipping a companion .bin was
misclassified as a plain checkpoint and routed through the wrong load path.
Factor the scanner's weight-name gating into shared _is_weight_bin /
_has_non_gguf_weights helpers and use them everywhere (also in
_dir_has_downloaded_model).
- PREFS_KEYS was missing the new 'Select model settings' keys (load on selection,
expand/show-all quantizations), so 'Reset all local preferences' left them set.
- On Device cached search dropped the active format filter while a query was
typed; keep matchesFormatFilter applied so the format dropdown stays consistent.
Adds tests for the tokenizer.bin vs weight-.bin classification.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: validate Ollama blobs, gate staged context, honor RAM budget on no-GPU hosts
- recommended-folders: only count an Ollama dir once its manifest resolves to an
on-disk model blob, so a failed/pruned pull no longer surfaces an empty chip
- GGUF variant click: only seed the staged contextLength for already-downloaded
picks, so choosing an undownloaded quant from a partially cached repo still
starts its download (the staging effect short-circuits on a known context)
- device fit: classify GGUF variants against the system-RAM budget on no-GPU /
unified-memory hosts instead of reporting everything as fits, and pass
systemRamGb to every variant expander regardless of gpu.available
* Studio: scope Hub search to Recommended, fix staged non-GGUF settings, keep local MLX on Mac
- model picker: only run the Hub search hooks on the Recommended section. On
Device / Connected render local data, so typing there no longer fires HF
requests or a spinner and the local/offline flow is preserved
- chat settings: when a pick is staged, decide the GGUF-only controls from the
staged model's type, not the currently loaded model's. A staged non-GGUF Hub
repo no longer inherits a loaded GGUF's context/KV/speculative controls
- On Device: keep local MLX builds in ./models selectable on Mac (chat-only ran
GGUF/MLX only, but the filter dropped MLX before the format toggle)

* Studio: mascot images degrade gracefully instead of showing alt text
Mascots loaded from raw public-folder URLs with no error handling, so a
missing or unreachable file (version skew during updates, subpath
mounts, transient blips) painted the alt text, like the empty mascot on
the training start overlay. A shared MascotImg now resolves against
BASE_URL, retries once with a cache-buster, then swaps to a 4 KB
fallback sloth bundled as a data URI that cannot 404. Applied to the
chat greeting, 404 page, training start overlay, auth form, onboarding
splash and wizard.
* Reset mascot retry state via key remount instead of render-time tracking
* Use MascotImg for the artifact generating panel sloth
Adds a self-contained RAG stack to Studio: knowledge bases with chunked indexing, hybrid (dense + lexical) retrieval, and an automatic first-pass context inject into chat. Embeddings run through a local llama-server GGUF backend (default unsloth/bge-small-en-v1.5-GGUF) with a sentence-transformers fallback. The chat tool loop gains a search_knowledge_base tool, a per-turn re-search cap, and source citation, layered on top of the shared ToolLoopController.
Trim and tighten code comments across studio/frontend TS/JS. Comment-only: every changed file verified code-identical to main via the TypeScript printer signature comparison.
* studio/frontend: fix onboarding CSP violations
Two onboarding-only CSP violations were showing up in the browser
console on a default install:
* `WizardSidebar` rendered the brand sticker from
`https://unsloth.ai/cgi/image/unsloth_sticker_no_shadow_*.png`,
which is not in the Studio CSP `img-src` allowlist. The sticker
rendered as a broken image.
* `Confetti` defaulted `globalOptions.useWorker` to `true`, so
`canvas-confetti` tried to spawn an OffscreenCanvas worker from
a `blob:` URL. CSP `script-src 'self'` blocks it; three blocked-
worker errors fired on the final wizard step.
Use the bundled `/sticker.png` for the brand image, and default
the Confetti wrapper to the main-thread fallback. CSP stays tight.
Resolves#5657.
* studio/frontend: harden CSP confetti fix + BASE_URL sticker
Address review feedback on #5658:
1. confetti.tsx
- Hoist the default globalOptions to a module-scope constant so the
prop default has a stable identity across renders (canvasRef's
dependency array no longer churns every render).
- Always force useWorker:false at the confetti.create site, regardless
of what the caller passed in globalOptions. Previously a caller that
set `{ resize: true }` would silently re-enable the worker and trip
the CSP block again.
- Add a lazily-mounted, module-scoped CSP-safe instance and route
ConfettiButton through it instead of the global confetti() (which
defaults to useWorker:true and would otherwise violate CSP).
2. confetti-fireworks.ts
- Replace the direct confetti(...) calls (global instance, default
worker on) with calls to a shared confetti.create instance with
useWorker:false. The guided-tour completion confetti no longer
trips the CSP block.
3. wizard-sidebar.tsx
- Use import.meta.env.BASE_URL prefix on the sticker src so the asset
still resolves when Studio is deployed under a subpath (e.g.
/studio/). Defaults to "/" so single-host installs are unchanged.
tsc clean, bun run build clean, bundle confirms the changes
(`{resize:!0,useWorker:!1}` appears in every relevant call site).
* studio/tour: preserve opts.zIndex on shared confetti fireworks canvas
Address chatgpt-codex-connector inline review on #5658 follow-up:
When canvas-confetti runs against a caller-provided canvas (which is
what we need for the CSP fix), the per-fire `zIndex` option is ignored
for stacking purposes -- the canvas element's own CSS `z-index` is what
the browser uses. The previous follow-up hard-coded the shared canvas
to `z-index:99999`, so callers that pass `opts.zIndex` (or expect the
old global-confetti behavior of being able to lower fireworks under an
overlay) silently lost that knob.
Apply `opts.zIndex` to the shared canvas's `style.zIndex` on each call
(default 99999 still used when omitted). Same default; behavior is now
restored for the lower/raise case.
The current only caller (`guided-tour.tsx` invoking
`fireConfettiFireworks()` with no args) is unaffected since it never
provided `opts.zIndex`. Public API contract is preserved.
* studio/frontend: drop dead ConfettiButton + BASE_URL onboarding mascots
- confetti.tsx: remove unused ConfettiButton + getSharedConfettiFire singleton (0 callsites)
- splash-screen.tsx, wizard-content.tsx: prefix sloth mascot paths with import.meta.env.BASE_URL so onboarding works under non-root subpaths
- confetti-fireworks.ts: drop dead per-fire zIndex from defaults (caller-provided canvas ignores it; we already drive stacking via canvas style)
* studio/frontend: BASE_URL on HF icon + race-safe shared fireworks init
- dataset-step.tsx: prefix the Hugging Face dataset-source icon with import.meta.env.BASE_URL so it resolves correctly under non-root deployments. Last onboarding asset that was still root-relative after the earlier BASE_URL sweep.
- confetti-fireworks.ts: cache the in-flight init promise in getSharedFire so two same-tick callers share the dynamic import and the appended overlay canvas. Previously two concurrent fireConfettiFireworks() calls each appended a fixed full-screen canvas and orphaned the first one.
* studio/frontend: tighten confetti CSP comments

* feat(studio): add Continued Pretraining (CPT) support
Implements CPT as a first-class training method in Unsloth Studio,
resolving feature request #4565.
Changes:
- frontend/src/types/training.ts: add 'cpt' to TrainingMethod union
- frontend/src/lib/vram.ts: add 'cpt' to VramTrainingMethod (fp16 footprint)
- frontend/src/features/export/constants.ts: add CPT to METHOD_LABELS
- frontend/src/features/training/api/mappers.ts: map 'cpt' -> 'Continued Pretraining',
force packing=true and train_on_completions=false for CPT payloads
- frontend/src/features/studio/sections/model-section.tsx: add 'Continued Pretraining'
option (purple dot) to Method selector; update tooltip
- frontend/src/features/onboarding/.../model-selection-step.tsx: add CPT to
onboarding wizard method dropdown
- backend/models/training.py: update training_type field description
- backend/core/training/worker.py: detect is_cpt flag, force packing=True,
train_on_completions=False, pass is_cpt to _train_worker
- backend/core/training/trainer.py: _train_worker reads is_cpt kwarg, forces
packing on, skips train_on_responses_only for raw-text pretraining
CPT behaviour:
- Full model weights (no LoRA adapters), same as Full Finetuning
- Sequence packing always enabled for GPU efficiency
- Trains on every token (no chat-format masking)
- VRAM estimated at fp16 (2.0 bytes/param)

Replace strikethrough + opacity-50 OOM styling with gray text and red pill badge across all Studio model selectors (chat, training, onboarding).
- Use gray-500/gray-400 for OOM model names (better contrast than strikethrough)
- Red pill badge for OOM indicator with light/dark mode support
- Scope GGUF gray override to quant name only so downloaded/recommended labels keep colors
- Add !important on TIGHT/OOM badges to resist ComboboxItem hover overrides
* fix: throttle and cache HuggingFace modelInfo API calls
The frontend was firing 40 to 60 parallel modelInfo requests on app
startup with zero caching or deduplication, causing HF rate limits.
Adds a caching layer (hf-cache.ts) with TTL cache, inflight request
dedup, and a concurrency limiter. Also debounces the HF token input
so typing a token no longer re-fires all model searches per keystroke.
* fix: only fetch VRAM info for visible models in chat selector
* Fix cache key isolation and VRAM badge stability for PR #4696
- Cache key now includes a token fingerprint (last 8 chars) instead of a
boolean, so switching HF tokens gives separate cache entries instead of
serving stale data from the previous token.
- Extract token via credentials?.accessToken to match the @huggingface/hub
API surface.
- Extend CachedResult type with safetensors/tags fields so downstream
consumers no longer need unsafe `as` casts.
- Merge VRAM param map with previous state on scroll instead of replacing
it, preventing a brief flash of missing VRAM badges when new models
become visible.
* Fix VRAM badges missing for search-filtered recommended models
When a user types a search query, filteredRecommendedIds can include
models beyond the currently visible page. These models had no VRAM data
because useRecommendedModelVram only received visibleRecommendedIds.
Now we pass the union of visibleRecommendedIds and filteredRecommendedIds
to the VRAM hook, so recommended models surfaced by search also show
their VRAM badges. The hf-cache layer ensures no duplicate network calls.
* Apply biome formatting to hf-cache.ts and use-recommended-model-vram.ts
Auto-formatted with biome check --write to match project lint rules:
- Block statements for single-line if/for bodies
- Import sorting (type imports first)
- Consistent line wrapping
* Fix extractToken to handle both current and deprecated HF auth forms
The @huggingface/hub CredentialsParams type is a union:
- { accessToken: "hf_..." } (current preferred form)
- { credentials: { accessToken: "..." } } (deprecated form)
Previously only checked params.credentials?.accessToken (deprecated path).
Now checks both forms so the cache key is correct regardless of which
calling convention is used.
* Simplify extractToken, map merge, and set construction
- extractToken: remove type assertions, use direct property access with
truthiness checks for cleaner union type handling
- VRAM map merge: use Map spread constructor instead of manual for loop
- idsForVram: use Set spread construction for more concise dedup
* Add rationale comment for MAX_CONCURRENT=3 in hf-cache.ts
* Skip GGUF repos in VRAM fetch and pre-populate cache from listModels
Two changes to reduce redundant HF API calls:
1. Filter GGUF repos from idsForVram before passing to useRecommendedModelVram.
GGUF repos have no safetensors metadata and the render layer already shows
a static "GGUF" badge -- fetching modelInfo for them is a no-op that wastes
a semaphore slot and a network round-trip.
2. Add primeCacheFromListing() to hf-cache.ts and call it from listModels
yield sites in mergedModelIterator and priorityThenListingIterator.
listModels returns the same type (ModelEntry & Pick<ApiModelInfo, T>) as
modelInfo with the same additionalFields, so the data is interchangeable.
Priming only writes if the key is not already fresh, so it never overwrites
a recent modelInfo response.
This means models discovered via listModels are already in cache when
useRecommendedModelVram later calls cachedModelInfo for them, eliminating
duplicate network requests.
* Fix cache key mismatch: prime both token and anonymous slots
The VRAM hook calls cachedModelInfo without credentials (anonymous key),
but listModels results were primed only under the authenticated key.
For authenticated users the priming was a no-op -- cache miss every time.
Fix: prime both the token-specific slot and the anonymous slot when an
access token is present. Public model metadata (safetensors, tags) is
identical regardless of auth so this is safe.
Also add a defensive guard in primeCacheFromListing for empty name.
* Auto-prime anonymous cache slot from authenticated modelInfo fetches
When cachedModelInfo is called with a token, the result was only stored
under the token-specific key (e.g. model::abc12345). The VRAM hook
calls cachedModelInfo without credentials and reads the anonymous slot
(model::anon), causing a cache miss and duplicate fetch for every
priority model.
Now cachedModelInfo also writes to the anonymous slot on success when
a token is present. Public model metadata (safetensors, tags) is
identical regardless of auth, so this is safe and eliminates ~10
duplicate API calls on first page load.
* Guard anonymous cache priming against gated/private models
Only prime the anonymous cache slot for non-gated, non-private models.
Previously, authenticated modelInfo responses and listing results were
unconditionally copied into the anonymous slot, which could briefly
expose gated/private model metadata after clearing the HF token.
Now checks result.gated and result.private before writing the anon slot.
Public unsloth/ models (the common case) still benefit from the
optimization; gated models like meta-llama/* require a fresh fetch
per auth context.
* Extract primeFromListing helper to deduplicate cache priming logic
The cache priming pattern (prime token slot + conditionally prime anon
slot for non-gated models) was duplicated in three places. Extracted
into a single primeFromListing() function for maintainability.
* Export CachedResult type, add isStale helper, simplify primeFromListing
- Export CachedResult so consumers can use it directly instead of
the indirect Parameters<typeof ...> pattern.
- Extract isStale(key) helper to deduplicate the cache freshness
check that was repeated in primeCacheFromListing, cachedModelInfo,
and the anonymous-slot priming logic.
- Simplify primeFromListing to use CachedResult directly for both
the data parameter and the gated/private guard, eliminating the
double cast.

Some models like unsloth/Qwen3-0.6B have no safetensors metadata
on Hugging Face, so the training model selector showed no parameter
size badge. The chat model picker already had extractParamLabel()
as a fallback that parses sizes like "0.6B" from the model name.
Add the same fallback to the training model selector and the
onboarding model selection step.

all disable thinking by default; 9B+ enables it)
- Always pass enable_thinking=False in AI Assist helper calls
(_run_with_helper and _generate_with_backend) regardless of chat

* studio: skip Shiki highlighting for incomplete SVG code fences
While streaming SVG content, the syntax highlighter (Shiki) re-parses
the entire growing SVG on every token, blocking the main thread and
freezing the code area until the fence closes. Show a plain-text
preview for incomplete SVG fences instead, similar to how Mermaid
diagrams show a placeholder while streaming.
* studio: fix default top_k from 50/40 to 20 for chat inference
Per Qwen3.5 docs (unsloth.ai/docs/models/qwen3.5), top_k should be 20
for both thinking and non-thinking modes. The model-specific config in
inference_defaults.json already had top_k=20 for Qwen3.5, but the
generic fallback defaults were wrong:
- Frontend DEFAULT_INFERENCE_PARAMS.topK: 50 -> 20
- Backend generate_chat_completion top_k: 40 -> 20
- Backend generate_chat_completion_with_tools top_k: 40 -> 20
- Frontend title generation top_k: 40 -> 20
* studio: set universal inference defaults for unknown models
Default params for any model without specific config:
temperature=0.6, top_p=0.95, top_k=20, min_p=0.01,
presence_penalty=0.0, repetition_penalty=1.0
Models with entries in inference_defaults.json (Qwen3.5, Gemma-3,
Llama, etc.) override these with their recommended values.
Updated in: frontend DEFAULT_INFERENCE_PARAMS, backend Pydantic
request models, and backend generate_chat_completion defaults.
* studio: only trust_remote_code for unsloth/ models in AutoConfig
Only set trust_remote_code=True when the model name starts with
"unsloth/". All other models default to False for safety.
* studio: move Generating spinner above the composer
The "Generating" spinner was below the send message bar, causing
the bar to jump up and down. Move it above the composer in both
the regular thread view and the welcome/empty view.
* studio: adjust toast close button position away from edge
Move the X close button on toasts (like "Starting model...") from
top-1.5 to top-3 and add right-3, giving more breathing room from
the top-right corner.
* studio: make Think button smaller with tighter icon-text gap
Reduce gap from 1.5 to 0.5, padding from px-2.5/py-1 to px-2/py-0.5,
and icon from size-3.5 to size-3.
* studio: multiple onboarding and chat UX improvements
- Move Generating spinner above composer (fixes jumping send bar)
- Make Think button smaller with tighter icon-text gap
- Chat card now inside grid (same size as Audio/Embeddings cards)
- Rename "Chat Only" to "Chat"
- Chat card requires Continue to proceed (no auto-advance)
- Continue on Chat selection skips onboarding and goes to /chat
- Tooltip (i) click on Chat card doesn't trigger navigation
- Step 1 footer Back button goes back to splash (label is "Back")
- Splash "Skip Onboarding" renamed to "Skip to Chat", navigates to /chat
- Toast close button moved away from edge
* studio: align Skip to Chat button, add Skip to footer
- Sidebar "Skip to Chat" now uses primary (green) Button style with
arrow icon, full width, aligned like step items. Shows on all steps.
- Footer: added "Skip" outline button next to Continue that goes
directly to /studio with progress saved (markOnboardingDone)
* studio: change default max steps from 30 to 60 in toggle hook
The DEFAULT_MAX_STEPS in use-max-steps-epochs-toggle.ts was still 30,
used as fallback when toggling from epochs back to max steps.
* studio: extend context length options to 262K
CONTEXT_LENGTHS now includes 65536, 131072, 262144 in addition to
the existing 512-32768 range. The onboarding step filters these by
the model's max_position_embeddings (e.g. Nemotron-3-Nano-4B has
262144), showing powers of 2 up to the model's maximum.
* studio: auto-select LoRA vs QLoRA based on model size and GPU memory
After selecting a model in onboarding, detect the total model weight
file size from HF Hub (safetensors/bin files). Then estimate memory
needed: model_size_gb * 1.5 * context_scale, where context_scale is:
- <=8192 tokens: 1.0x
- >8192 tokens: 1.7x
- >=16384 tokens: 2.0x
- >=32768 tokens: 4.0x
If the estimate fits in free GPU VRAM, default to LoRA (16-bit).
Otherwise default to QLoRA (4-bit).
Backend changes:
- Add model_size_bytes to ModelDetails (models.py)
- Add _get_model_size_bytes() using HfApi.repo_info (routes/models.py)
- Add vram_free_gb to get_gpu_summary (hardware.py)
Frontend changes:
- Add autoSelectTrainingMethod() in training-config-store.ts
- Called after model defaults are loaded
- Add model_size_bytes to ModelConfigResponse type
- Add vramFreeGb to HardwareInfo hook

for more information, see https://pre-commit.ci
* studio: rename 'Skip to Chat' to 'Skip Onboarding' on splash screen
* studio: add presence_penalty support for chat inference
Add presence_penalty as a parameter across the full stack:
- Backend: llama_cpp.py generate_chat_completion/with_tools, Pydantic
models (inference.py), routes/inference.py pass-through
- Frontend: InferenceParams type, DEFAULT_INFERENCE_PARAMS (0.0),
chat-adapter.ts payload, chat-settings-sheet.tsx slider (0-2),
model defaults loading from inference_defaults.json
- Set Qwen3.5 default presence_penalty to 1.5 per official docs
- Default for unknown models is 0.0 (off)
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* studio: fix Chat card deselecting Text and aligning with other cards
* studio: fix presence_penalty not loading from inference defaults
The inference_config.py load_inference_config() was not including
presence_penalty in the returned config dict, so the Qwen3.5
default of 1.5 from inference_defaults.json never reached the
frontend. Added it to the config builder.
* studio: add delete button for cached models in model selector
Add trash icon on each downloaded model row (GGUF and safetensors) with
confirmation dialog. Backend DELETE /api/models/delete-cached endpoint
uses huggingface_hub scan_cache_dir + delete_revisions to cleanly remove
cached repos, refusing if the model is currently loaded.
* studio: restore inference defaults, reasoning, and tools on page refresh
On page refresh with a model already loaded, the frontend was not
re-applying model-specific inference defaults (presence_penalty,
temperature, etc.) or restoring reasoning/tools support flags.
Backend: Add inference config, supports_reasoning, supports_tools,
and context_length to InferenceStatusResponse.
Frontend: In the refresh callback, when an active model is detected,
apply mergeRecommendedInference and restore reasoning/tools flags
with proper Qwen3.5 size-based defaults.
* studio: fix delete dialog closing before async completes
Prevent AlertDialogAction's default close behavior with
e.preventDefault() so the dialog stays open during deletion.
Also block onOpenChange dismiss while deleting is in progress.
* fix: add Dict and Any imports to inference models
* studio: fix Qwen3.5 reasoning threshold in frontend load path
The frontend loadModel handler had the old threshold (<=2) for
disabling reasoning on small Qwen3.5 models. Changed to <9 to
match the backend. This was causing 4B to not properly disable
thinking by default when auto-loaded.
* studio: move GGUF delete to per-variant level
For GGUF repos, the trash icon now appears on each downloaded variant
row inside the quantization expander instead of on the repo-level row.
Backend accepts optional variant param to delete specific GGUF files
(blob + symlink) rather than the entire repo cache.
* studio: restore ggufContextLength on page refresh
The Max Tokens slider was capped at 32768 on page refresh because
ggufContextLength was not restored from the status response.
Now set it from statusRes.context_length on reconnect.
* fix: remove <think> from Qwen3.5 response template marker
The train-on-responses-only feature uses template markers to find
where the assistant response starts. The Qwen3.5 response marker
included '<think>\n' which is only present when thinking mode is
enabled. With thinking disabled (default for <9B), the marker
never matched, causing 100% of samples to be dropped.
Changed response marker from '<|im_start|>assistant\n<think>\n'
to '<|im_start|>assistant\n' which works regardless of thinking mode.
* studio: fix sloth ASCII art alignment in training overlay
* fix: correct sloth ASCII art alignment to match Unsloth banner
* studio: add Python and terminal tool calling to chat
Register python and terminal tools alongside web search. Python
executor validates imports (stdlib only) via unsloth_zoo
rl_environments, runs code in a subprocess sandbox with 5-min
timeout and cancel support. Terminal executor blocks dangerous
commands (rm, sudo, etc.) and runs in a temp directory.
Update llama_cpp tool loop to show tool-specific status messages
and pass cancel_event through to executors. Rename composer
toggle from "Search" to "Tools" and show TerminalIcon for
execution status pills.

* studio: fix Nemotron/transformers 5.x support, onboarding navigation, port binding
Backend:
- Dynamic transformers 5.x detection via tokenizer_config.json fetch
(checks for TokenizersBackend class, cached per-model)
- Bump transformers 5.x version from 5.2.0 to 5.3.0 across all workers,
setup scripts (setup.sh, setup.ps1)
- Auto-enable trust_remote_code for unsloth/* models needing transformers 5.x
(workaround for NemotronH config parsing bug in transformers)
- Auto-install mamba-ssm/causal-conv1d for SSM models (NemotronH, Falcon-H1)
with --no-build-isolation --no-deps to avoid torch version conflicts
- Add SO_REUSEADDR to port check in run.py (fixes Colab proxy stale connection
falsely reporting port as in-use)
Frontend:
- Fix "Skip to Chat" navigation: use window.location.href instead of React
Router navigate() to bypass useEffect redirect race
- Fix "Skip Onboarding" on splash: navigates to /studio (not /chat)
- Fix onboarding guard: only check isOnboardingDone() on initial mount
- Fix Chat card on step 1: add sr-only spacer for consistent alignment
- Fix Chat+Text both selected: clear RadioGroup value when Chat is selected
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* studio: split tools toggle into Search and Code buttons
Replace the single "Tools" toggle with two independent toggles:
- "Search" (globe icon) enables web search only
- "Code" (terminal icon) enables Python and terminal execution
Add enabled_tools list field to the inference payload so the
backend only registers the tools the user has toggled on. Both
toggles appear in the main composer and the compare composer.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* studio: fix tool calling import validation and error logging
Replace unsloth_zoo-dependent import checker with a standalone
ast-based validator using sys.stdlib_module_names. This properly
blocks non-stdlib imports (numpy, requests, etc.) and returns a
clear error message to the model so it can rewrite using only
stdlib.
Add full traceback to tool streaming error logs for debugging.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* fix: parse gpt-oss harmony channels for clean safetensors chat output
gpt-oss models emit multi-channel output via harmony protocol tokens
(<|channel|>analysis<|message|>... and <|channel|>final<|message|>...).
TextIteratorStreamer with skip_special_tokens=True strips the special
tokens but leaves channel names concatenated with content, producing
garbled output like "analysisWe need to...assistantfinalHello!".
Add HarmonyTextStreamer that decodes with skip_special_tokens=False,
parses harmony markup via regex, and emits <think>analysis</think>
for the analysis channel and plain text for the final channel --
reusing the existing frontend reasoning UI.
Also expose supports_reasoning=True for non-GGUF gpt-oss models in
the /status endpoint so the frontend enables the Think toggle.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* studio: use unsloth_zoo for Python sandbox validation
Set UNSLOTH_IS_PRESENT=1 and import check_python_modules and
check_signal_escape_patterns directly from unsloth_zoo instead
of a standalone fallback. This gives us the full Unsloth
validation including stdlib-only import checks and signal/timeout
escape pattern detection.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* studio: allow all imports in Python tool sandbox
Remove stdlib-only import restriction. Keep signal escape
pattern detection via unsloth_zoo for safety.
* studio: fix ReadTimeout on tool streaming final pass
The 0.5s read timeout used for cancel-checking during streaming
also fires when waiting for the first response from llama-server
(e.g. reasoning model thinking for 15+ seconds). Add
_stream_with_retry() context manager that retries on ReadTimeout
while checking cancel_event, so the model has unlimited time to
think before producing the first token. Applied to both the
regular streaming path and the tool-calling final pass.
* fix: rewrite HarmonyTextStreamer with stateful incremental parsing
The delta-on-transformed approach had two critical bugs:
1. Before the full <|channel|>X<|message|> pattern was complete, the
strip-tokens fallback emitted "analysis" as plain text. Then when
the regex matched, _transform returned a completely different format
(<think>...</think>) and the delta was computed against the wrong
base string, producing fragments like "think>", "nk>", ">".
2. Even with full matches, the closing </think> tag shifted position
as content grew, so text[prev_len:] produced garbled deltas.
Replace with stateful incremental parsing that:
- Buffers until a complete channel+message pair is seen
- Emits <think> once when analysis channel first appears
- Streams analysis content deltas (computed on channel content directly)
- Emits </think> once when final channel first appears
- Streams final content deltas
- Closes open think tags in end()
Also skip the generic all_special_tokens stripping in
_clean_generated_text for gpt-oss since HarmonyTextStreamer already
produces clean output and the generic stripping was mangling <think>
tags.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* fix: strip all <|...|> tokens in gpt-oss cleanup, not just harmony subset
The gpt-oss tokenizer has added tokens like <|return|> (id=200002) that
are not part of the harmony channel protocol but can leak into output.
The previous regex only stripped channel|message|start|end tokens.
Broaden the _clean_generated_text regex for gpt-oss to <\|[a-z_]+\|>
which catches all pipe-delimited tokens (return, constrain, reserved,
etc.) without matching <think>/<\/think> tags.
Verified: gpt-oss all_special_tokens are only <|return|>,
<|reserved_200017|>, <|startoftext|> -- none overlap with <think>.
The harmony tokens (channel, message, start, end) are added_tokens
but not in all_special_tokens.
* fix: hide config-only model repos from cached models list
Repos that only have metadata/config files cached (no .safetensors or
.bin weight files) were showing up in the Downloaded list with tiny
sizes like "1.8 KB" or "24 KB". These are just leftover config
snapshots from architecture checks, not usable models.
Filter the cached-models endpoint to only include repos that contain
actual model weight files (.safetensors or .bin).
* studio: fix toast description text contrast in dark mode
Add explicit !text-muted-foreground to toast description classNames
so secondary text (e.g. "Releases VRAM and resets inference state.")
is readable in dark mode.
* studio: fix Chat card icon alignment with size-4 spacer
Replace sr-only span (takes no space) with a size-4 shrink-0 div
matching the RadioGroupItem dimensions in other cards, so the Chat
icon aligns vertically with Text/Audio/Vision/Embeddings icons.
