* Studio: bulk export and import in Settings Chat Data, MCP pill off switch
- Settings -> Chat -> Data gains Export Recents and Projects (Recents or
Recents + Projects, Raw JSONL / CSV / ShareGPT, combined or per chat)
and Import chats, reusing the sidebar Recents menu actions
- Extract bulkExportConversationsByScope so the sidebar and Settings share
one implementation; expose the export and import helpers via the chat
feature index
- MCP composer pill icon now swaps to an X on hover like Search, Code and
RAG; clicking it turns MCP off without opening the server menu
- en and zh-CN locale strings added (parity check passes)
* Reveal the pill X on hover for off-switch icons regardless of active look
The X was gated on data-active, so an MCP pill with no servers enabled
(or a RAG pill without a model) closed on icon click but never showed
the affordance. Off-switch pills only render while their feature is on,
so hover now always reveals the X.
* Replace the Recents hamburger menu with an Export all chats link to Settings
Bulk export and import now live in Settings -> Chat -> Data, so the
sidebar Recents header menu is gone. Each chat's Export submenu gains
Export all chats, which opens Settings on the Chat tab.
* Fix Windows installer winget msstore certificate failure
`winget install` was invoked without `--source winget`, so winget also
queried the msstore source. When msstore fails certificate pinning
(error 0x8a15005e, "The server certificate did not match any of the
expected values") winget aborts and demands `--source`, so the Python
(and uv) install fails even though the package exists in the winget
source.
- Pass `--source winget` to all winget install calls (Python x2, uv).
Both packages live in the winget source, so this is strictly correct
and skips the failing msstore round-trip entirely.
- Add a python.org fallback (Install-PythonFromPythonOrg) that downloads
the official installer and runs it silently per-user (no admin/UAC)
when winget is unavailable or fails for any reason. Mirrors the
existing uv -> astral.sh fallback so Python installs without manual
steps. Resolves the latest 3.13.x from python.org with a pinned
fallback, and selects the amd64/arm64/x86 installer per architecture.

* Pin remaining setup.ps1 winget calls to --source winget
Two winget invocations in studio/setup.ps1 still queried all sources and
could hit the same msstore certificate-pinning failure (0x8a15005e) that
broke the Python install in install.ps1:
- `winget show Nvidia.CUDA --versions` (CUDA Toolkit version probe)
- `winget install ... ShiningLight.OpenSSL.Dev` (OpenSSL dev for llama-server)
Every other winget call in this file already passes `--source winget`
(Git, CMake, VS Build Tools, CUDA install, Node.js, and setup.ps1's own
Python 3.12 install), so these two were stragglers. Both packages live in
the winget source; pinning it makes setup robust to an unhealthy msstore
source, matching the rest of the file.

* Stop amd-smi GPU probe from popping a DiskPart UAC prompt
On Windows, AMD GPU detection in install.ps1 and studio/setup.ps1 runs
`amd-smi list` / `static --asic` / `version`. amd-smi (shipped in
System32 by the Adrenalin driver) auto-elevates to read GPU/APU memory
details, surfacing a confusing DiskPart UAC prompt mid-install. The
Studio backend already documents and circuit-breaks on this in
studio/backend/utils/hardware/amd.py, but the installers did not.
Add an Invoke-AmdSmiNoElevate helper (both scripts) that runs amd-smi via
Start-Process under __COMPAT_LAYER=RunAsInvoker so it cannot auto-elevate
(no prompt), with a 30s timeout (matching amd.py) so a flaky amd-smi
cannot stall the install for minutes. On failure/timeout the existing WMI
name -> gfx fallback still resolves the arch, so detection is unchanged on
working hosts.
Verified on a Strix Halo (Radeon 8060S / gfx1151) box: the prompt is gone
and the probe is bounded.

* Add experimental ROCm-on-WSL setup helper for Strix Halo (gfx1151)
install.sh already routes gfx1151 (Radeon 8060S / Strix Halo) to the
repo.amd.com/rocm/whl/gfx1151 wheels once a ROCm runtime is present, but
it does not install AMD's driver/ROCm stack -- a large, admin-gated
prerequisite. scripts/install_rocm_wsl_strixhalo.sh automates the Linux
side on a dedicated Ubuntu 24.04 WSL2 distro: ROCm 7.2 (wsl usecase), the
rocr4wsl HSA runtime, a librocdxg build, env setup, and a PyTorch gfx1151
GPU smoke test. A hard preflight refuses to run until the Adrenalin
>=26.3.1 driver is actually present, so it cannot half-install.
Procedure adapted from AMD's ROCm-on-WSL docs and community gfx1151 notes.

* Detect AMD GPUs by name so native Windows gets a GPU llama.cpp
The gfx-arch inference from the WMI GPU name was gated behind $HasROCm,
which the hipinfo/amd-smi probe leaves false on the common Windows case
(Adrenalin driver only, no HIP SDK -- and amd-smi often cannot read the
arch without elevation). So an AMD GPU was detected by name but never
mapped to a gfx target, --rocm-gfx was not forwarded, and studio setup
fell back to a CPU llama.cpp build.
Un-gate the inference (install.ps1 + studio/setup.ps1) so it runs whenever
an AMD GPU name is available. The inferred gfx is forwarded as --rocm-gfx,
which makes install_llama_prebuilt.py download the matching lemonade-sdk
ROCm prebuilt (e.g. llama-bNNNN-windows-rocm-gfx1151-x64.zip) -- a
GPU-accelerated llama.cpp that bundles its own ROCm runtime, so it runs
with just the Adrenalin driver. PyTorch's ROCm wheels still require a
confirmed HIP SDK ($HasROCm), so this only affects llama.cpp / inference
and never pulls broken ROCm torch.
Also broaden the name->arch table to every family lemonade ships Windows
assets for: gfx120X (RDNA 4), gfx110X (RDNA 3), gfx1151/gfx1150
(RDNA 3.5), and gfx103X (RDNA 2). Unknown names still fall back to CPU.

* Suppress amd-smi DiskPart UAC prompt in the Python install/runtime paths
The earlier PowerShell guard covered install.ps1 / setup.ps1, but the
Python installer (install_llama_prebuilt.py detect_host,
install_python_stack.py ROCm probes) and the Studio backend monitor
(amd.py) also shell out to amd-smi on Windows, where it auto-elevates and
pops the same DiskPart UAC prompt mid-install / at runtime.
Inject __COMPAT_LAYER=RunAsInvoker into the amd-smi subprocess env on
Windows so it runs un-elevated (no prompt). Callers already tolerate an
empty/failed result and fall back to WMI / name detection (installer) or
the existing circuit breaker (amd.py). Gated to Windows so Linux/macOS
amd-smi behaviour is unchanged.
- install_llama_prebuilt.py: handled centrally in run_capture (covers
detect_host's `amd-smi list` and the version probe).
- install_python_stack.py: new _amd_smi_env() helper on its 3 raw
subprocess.run amd-smi calls.
- amd.py: merge RunAsInvoker into the existing child env.

* Tighten AMD GPU name->arch patterns to avoid mismatches
The W9[0-9]{3} and RX 90[0-9]{2} patterns added for RDNA 4 were
speculative and over-broad: W9xxx would also match old GCN FirePro
W9100/W9000 cards (wrong gfx1201 -> a lemonade gfx120X download that
fails validation), and RX 90[0-9]{2} was redundant with the explicit
9070/9060 entries. Drop both; keep only confirmed RDNA 4 SKUs. Unmatched
AMD names still fall back cleanly to CPU.

* Fetch the llama.cpp validation model via huggingface_hub
The prebuilt validation downloads a tiny GGUF test model from huggingface
via bare urllib. On Windows / proxy setups where the server sends an
incomplete TLS chain, urllib cannot complete the Amazon CA chain (it does
no AIA intermediate fetching) and fails with CERTIFICATE_VERIFY_FAILED, so
a perfectly good GPU prebuilt is rejected and the installer falls back to a
CPU source build.
Route the validation-model download through huggingface_hub
(hf_hub_download) -- the same mechanism Studio uses for model downloads,
which completes the chain where urllib cannot -- keeping the direct URL as
a fallback. This lets the lemonade ROCm prebuilt validate and install on
cert-restricted machines (verified: hf_hub_download succeeds where urllib
returns CERTIFICATE_VERIFY_FAILED).

* Guard the remaining raw amd-smi version probe via run_capture
A ROCm-version detector in install_llama_prebuilt.py called amd-smi version through a raw subprocess.run that bypassed run_capture's Windows RunAsInvoker guard, so it still triggered the DiskPart UAC prompt during setup. Route it through run_capture like the other amd-smi calls.

* Forward --rocm-gfx even when the ROCm runtime is unconfirmed
setup.ps1 forwarded --rocm-gfx (and picked the windows-hip llama.cpp
prebuilt) only inside `if ($HasROCm)`. On Adrenalin-only hosts (amd-smi
present but no HIP SDK, so $HasROCm stays false) the gfx arch was
name-inferred but never forwarded, so install_llama_prebuilt.py saw
has_rocm=False and installed the CPU build -- even though the lemonade
gfx1151 GPU prebuilt runs fine there (it bundles its own ROCm runtime;
verified: llama-cli --list-devices -> ROCm0: AMD Radeon 8060S, 69 GB).
Forward --rocm-gfx whenever a gfx arch is known (it is authoritative and
implies ROCm in install_llama_prebuilt.py), and treat a known gfx arch as
windows-hip in the existing-install mismatch check. --has-rocm stays gated
on the confirmed-runtime signal.
Verified on Radeon 8060S / gfx1151: the installer now selects, validates,
and installs llama-b1286-windows-rocm-gfx1151-x64.zip (ROCm DLLs present)
instead of the CPU build.

* Install AMD ROCm PyTorch on name-inferred gfx hosts (enables Train/Export)
setup.ps1 picked the AMD ROCm PyTorch wheels only inside `if ($HasROCm ...)`.
On Adrenalin-only hosts (amd-smi present but no HIP SDK, so $HasROCm is
false) the gfx arch was name-inferred but the ROCm-wheel branch never ran,
so the host got torch+cpu. With CPU torch, torch.cuda.is_available() is
False, so the Studio backend sets CHAT_ONLY=True and hides Train/Export.
Un-gate the ROCm PyTorch index resolution on a known gfx arch (mirrors the
llama.cpp --rocm-gfx fix). AMD's per-arch Windows wheels
(repo.amd.com/rocm/whl/<gfx>) bundle the ROCm runtime, so they work without
a HIP SDK; a failed install still falls back to CPU.
Verified on Radeon 8060S / gfx1151: torch 2.11.0+rocm7.13.0 installs and
torch.cuda.is_available() -> True, device "AMD Radeon(TM) 8060S Graphics",
GPU matmul OK -> CHAT_ONLY=False -> Train/Export enabled.

* Force amd-smi un-elevated process-wide in the Python installers
Guarding individual amd-smi call sites kept missing some (install_python_stack.py's probe loop and its Windows GPU re-check), so the DiskPart UAC prompt kept reappearing. Set __COMPAT_LAYER=RunAsInvoker process-wide at the top of install_python_stack.py and install_llama_prebuilt.py on Windows so every amd-smi subprocess (current and future) runs un-elevated with no per-call guard. Safe: these scripts only spawn amd-smi/rocminfo/hipinfo probes and pip/uv. setup.ps1 keeps per-call guards because it also spawns winget installers that need elevation.

* Fix Invoke-AmdSmiNoElevate exit code on PS 5.1 + RX 7700S arch match
Start-Process -PassThru leaves the returned process object's .ExitCode
$null after WaitForExit on Windows PowerShell 5.1, so the helper set
$LASTEXITCODE to $null and every caller's `if ($LASTEXITCODE -eq 0 ...)`
was always false -- the amd-smi GPU / gfx-token / ROCm-version detection
branch was effectively dead (masked only because the un-gated WMI
name->gfx inference still ran). Reproduced on PS 5.1.26100.
Rewrite the helper to use [System.Diagnostics.Process]::Start with a
ProcessStartInfo (UseShellExecute=false), whose .ExitCode is reliable,
with async stream reads (ReadToEndAsync) to avoid a pipe-buffer deadlock
and WaitForExit(timeout) to bound a flaky amd-smi. __COMPAT_LAYER=
RunAsInvoker (inherited via the process env) still suppresses the
auto-elevation / DiskPart prompt. Also drops the temp files and the
empty-ArgumentList edge case. Verified: exit code propagates
(7 -> $LASTEXITCODE=7), output captured, env restored.
Also fix the gfx1100 name pattern `RX 7700(?! S)` -> `RX 7700(?!S)` so the
spaceless retail name "RX 7700S" is correctly excluded (it belongs to the
gfx1102 row). Both found by PR review.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* Address PR review follow-ups (install.sh table, update path, tests, WSL)
From the multi-agent PR review:
- install.sh: sync the AMD name->arch table with install.ps1 / setup.ps1
(the bash table had drifted to the old narrow patterns). Adds RDNA 2
(gfx103X), workstation PRO W SKUs, and more Strix Halo/Point names, and
orders gfx1102 before gfx1100 so the spaceless retail name "RX 7700S"
resolves correctly (bash case has no negative lookahead). AMD-ROCm-only:
the name inference stays gated behind _has_amd_rocm_gpu(), so NVIDIA /
CPU / macOS are unaffected.
- setup.ps1: the "dependencies up to date" fast path skipped the torch
reinstall, so an existing user who had CPU torch (installed before
ROCm-wheel support) stayed stuck in CHAT_ONLY. Now, when an AMD gfx arch
is known AND the installed torch is CPU-only, don't skip -- force the
dependency pass so the ROCm wheels install.
- scripts/install_rocm_wsl_strixhalo.sh: resolve the real /opt/rocm dir
instead of hardcoding ROCM_VER for LD_LIBRARY_PATH / the librocdxg
symlink (breaks if amdgpu-install lays ROCm under a patch-version dir);
add a LIBROCDXG_REF pin knob and a "verified against" freshness header.
- tests/studio/install/test_pr5940_followups.py: cover _hf_resolve_url_parts,
_fetch_validation_model_bytes (hf path + urllib fallback), run_capture's
Windows-only amd-smi RunAsInvoker injection, and install.ps1 vs setup.ps1
name-table parity (catches future drift). 14 tests, all passing.

* Fix DiskPart UAC prompt: skip amd-smi on Windows without a HIP SDK
On Windows, amd-smi re-initialises the ROCm runtime on every invocation
(even `amd-smi version`) and, on hosts without a working HIP runtime
(consumer APUs/dGPUs with only the Adrenalin driver), elevates a child
process at runtime -- popping a UAC/DiskPart prompt. amd-smi's own
manifest is asInvoker, so __COMPAT_LAYER=RunAsInvoker cannot suppress
that runtime elevation (verified: even `amd-smi version` hangs and
times out with RunAsInvoker set).
Replace the ineffective RunAsInvoker-only approach with a real gate:
only spawn amd-smi on Windows when a HIP SDK is detectable (hipinfo
present, so amd-smi runs un-elevated) or the user opts in with
UNSLOTH_ENABLE_AMD_SMI=1. The gfx arch is already resolved from WMI
name inference (forwarded via --rocm-gfx), so ROCm wheel + lemonade
llama.cpp selection is unaffected. Linux/macOS amd-smi never elevates
and is untouched (no regression). RunAsInvoker is kept as harmless
belt-and-suspenders for tools that DO use manifest elevation.
Applied consistently across:
- studio/backend/utils/hardware/amd.py (runtime GPU polling)
- install.ps1, studio/setup.ps1 (install-time detection)
- studio/install_llama_prebuilt.py (prebuilt arch probe + version)
- studio/install_python_stack.py (ROCm version + arch probe)
Verified live on AMD Radeon 8060S (gfx1151), native Windows: fresh
install detects the GPU, installs ROCm torch (torch.cuda.is_available()
True), launches Studio with no DiskPart prompt, and inference, tool
calling, web search, LoRA finetuning, and GGUF export all run on the GPU.
Tests: add 6 _amd_smi_allowed() gating tests + PowerShell-installer gate
assertions; update the three amd-smi monitoring tests to opt in (they
mock amd-smi as available). Full suite: 267 passed, 2 skipped.

* install.sh: helpful WSL message when the GPU isn't exposed to ROCm
In WSL, an AMD GPU's ROCm-on-WSL runtime is only available with a recent
Adrenalin driver AND a distro AMD supports (currently Ubuntu 24.04). When
neither is in place, GPU detection (rocminfo/_has_amd_rocm_gpu) finds
nothing and we silently fall back to CPU.
Add an actionable hint in the CPU-fallback path, shown only on WSL and
only AFTER detection has already failed -- so it is forward-compatible:
the moment a driver/distro DOES expose the GPU (e.g. if AMD later adds
Ubuntu 26.04 support), detection succeeds and the hint never fires. The
message:
- notes a GPU is plumbed in (/dev/dxg) but no ROCm runtime is exposed,
- lists the two prerequisites (Adrenalin driver + Ubuntu 24.04),
- if the distro is not 24.04, says AMD may not support it yet,
- tells the user to `wsl --install Ubuntu-24.04` and re-run,
- links AMD's ROCm-on-WSL guide + the experimental Strix Halo helper.
Verified live: on Ubuntu-24.04 the hint shows (version-warning omitted)
and the CPU install completes; on Ubuntu-26.04 the extra "this distro may
not be supported" line appears and points to 24.04.
Also fix the experimental scripts/install_rocm_wsl_strixhalo.sh: AMD's
repo.radeon.com/amdgpu-install/ is indexed by unified installer version
(30.30, 31.30, ...), NOT ROCm version, so the hard-coded
amdgpu-install/7.2.0/ path 404'd. Scan the installer dirs newest-first
for a noble .deb matching the target ROCm major.minor (ROCm 7.2 ->
30.30.x/amdgpu-install_7.2.x), falling back to the newest available.

* WSL: fix shortcut collision + pin ROCm-on-WSL driver reqs from AMD docs
Two WSL-related fixes informed by AMD's official ROCm-on-WSL docs and
field reports for Strix Halo / Ryzen AI Max+ (Radeon 8060S, gfx1151):
1. Shortcut collision (real bug). install.sh's WSL branch wrote
"Unsloth Studio.lnk" to the SAME Desktop / Start Menu folder as the
native-Windows installer (install.ps1 New-StudioShortcuts). Running
install.sh in WSL therefore silently retargeted the native shortcut at
the WSL launcher (wt.exe -> wsl.exe), so the desktop/start-menu icon
stopped launching native GPU Studio. Now the WSL shortcut uses a
DISTINCT name -- "Unsloth Studio (WSL - <distro>).lnk" -- and fetches
the Unsloth .ico to %LOCALAPPDATA%\Unsloth Studio so it shows the
proper icon. Native and WSL shortcuts now coexist.
2. Precise ROCm-on-WSL prerequisites. Research (AMD radeon-ryzen WSL
compatibility matrix, gianni.rosagallina.com Feb-2026 guide,
ROCm/ROCm#4952/#5509/#6022) confirms WSL GPU on Strix Halo requires
AMD Adrenalin Edition >= 26.1.1 (26.2.2+ is the first production
ROCDXG/WSL release) + ROCm 7.2.1 + Ubuntu 24.04; an older driver does
not inject the ROCm/DXG runtime into /usr/lib/wsl/lib, so rocminfo sees
only the CPU. install.sh's WSL hint and the experimental
install_rocm_wsl_strixhalo.sh header/preflight now state the exact
driver version (was a guessed ">=26.3.1"), bump ROCM_VER to 7.2.1, link
AMD's radeon-ryzen docs, and document the known librocdxg caveat that
usable VRAM is currently capped at the .wslconfig memory setting.

* installer: hint when the AMD driver is too old for ROCm-on-WSL
Adds a detect-and-guide hook for the optional WSL-GPU path. An AMD GPU on
native Windows can also be used inside WSL2, but only with AMD Adrenalin
Edition >= 26.2.2 (the first production ROCDXG/WSL release). Native Windows
GPU works with any recent driver, so this is purely about enabling the WSL
path.
We intentionally do NOT auto-install the driver: AMD referrer-gates driver
downloads (scripted curl/Invoke-WebRequest are blocked) and does not publish
Adrenalin via winget, so no installer can reliably fetch it -- and silently
swapping a live display driver is risky. Instead we point the user at AMD's
official download page (one click), after which the existing WSL detection
lights up automatically.
- install.ps1: new Show-AmdWslDriverHint -- when an AMD GPU is present and the
installed driver predates the 26.2.2 release (DriverDate < 2026-02-01),
print a concise tip with the AMD download URL. Handles DriverDate as either
a CIM DateTime or a WMI string. Suppress with UNSLOTH_SKIP_AMD_DRIVER_HINT=1.
- install.sh (WSL hint): add the direct Adrenalin 26.2.2 download URL and note
that AMD downloads are referrer-gated (open in a browser).
Verified: hint fires on a Sept-2025 driver, auto-suppresses on >= 2026-02-01;
install.ps1 parses; install.sh bash -n clean; suite 267 passed, 2 skipped.

* install.ps1: refresh shell icon cache after creating the shortcut
After writing the Desktop / Start Menu .lnk, nudge Explorer to refresh
its icon (ie4uinit.exe -show). Without this, a stale icon cache can show
a blank shortcut icon until the next explorer restart -- most visible
when a shortcut of the same name was rewritten (e.g. a native install
followed by a WSL install, which previously shared the name; now they use
distinct names, but the cache nudge makes the icon appear immediately
regardless). Best-effort and wrapped in try/catch so it never fails the
install. The bundled unsloth.ico itself is valid (verified it renders).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* setup.ps1: don't silently CPU-build llama.cpp on an AMD GPU
For AMD, GPU acceleration comes from the lemonade ROCm prebuilt (it bundles
the ROCm runtime, no HIP SDK needed) and is the preferred/default path. The
source-build fallback is CPU-only -- a HIP/ROCm *source* build would need the
full HIP SDK + ROCm clang toolchain, which the prebuilt exists to avoid.
Previously, if an AMD-GPU host ever fell through to the source build (e.g. the
prebuilt could not be downloaded), it printed "building llama.cpp (CPU-only,
no NVIDIA GPU detected)" and quietly produced a CPU binary -- masking the lost
GPU acceleration. Now that case emits a loud [WARN] explaining the GPU prebuilt
is the AMD path and how to restore it (re-run / check network / set
UNSLOTH_LLAMA_RELEASE_TAG), so AMD never silently degrades to CPU.
No behavior change on the happy path: AMD still gets the GPU prebuilt (verified
on gfx1151: ggml-hip.dll bundled, ~80% GPU compute during inference). NVIDIA
(CUDA source build) and CPU-only hosts are unchanged.

* uninstall: remove shared llama.cpp build, kill lock-holders, match WSL shortcut
Three gaps found by running a real uninstall on a native-Windows + WSL host;
all fixes are scoped to Unsloth-owned paths and no-op on the other pathways
(env/custom-root, NVIDIA/AMD/CPU, Mac) so nothing else regresses.
uninstall.ps1:
- Remove the default-mode SHARED llama.cpp build + cache. setup.ps1 installs
them at ~/.unsloth/llama.cpp and ~/.unsloth/.cache -- SIBLINGS of studio,
not under it -- so deleting <studio> left hundreds of MB behind. Now removed
explicitly, then ~/.unsloth is dropped ONLY if empty (never nukes unrelated
content). No-op in env/custom mode (llama.cpp nests under the custom root,
removed already) and when absent. UNSLOTH_LLAMA_CPP_PATH (user-owned) is kept.
- New _StopProcessesLockingRoots: _StopStudioProcesses only matched the venv
unsloth/python/studio exe, so it missed (a) llama-server.exe under llama.cpp
and (b) an orphaned multiprocessing python fork that ran from the SYSTEM
python but loaded a venv DLL (bitsandbytes) -- on Windows an open DLL handle
blocks the directory delete, leaving a half-removed install. The new helper
kills any process whose image path OR loaded module is under a target root
(module scan scoped to python/unsloth/llama-server names; vendor-agnostic).
- _RemovePath now retries (transient post-kill handle release).
uninstall.sh:
- Remove the default-mode ~/.unsloth/llama.cpp + ~/.unsloth/.cache; rmdir
~/.unsloth only if empty.
- WSL Windows-side shortcut cleanup now matches by TARGET (any
"Unsloth Studio*.lnk" whose target launches wsl.exe), covering both the
legacy "Unsloth Studio.lnk" and the new "Unsloth Studio (WSL - <distro>).lnk"
-- and never removes a native-Windows shortcut (which launches wscript.exe).
uninstall.ps1 parses; uninstall.sh passes sh -n and bash -n.

* install.ps1: invalidate Win11 Start Menu tile cache after creating shortcut
The Start Menu shortcut kept showing a blank/generic icon even after the
Explorer icon-cache rebuild, because Windows 11's StartMenuExperienceHost
keeps its OWN pre-rendered tile-icon cache
(%LOCALAPPDATA%\Packages\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy\
TempState\TileCache_*.bin + StartUnifiedTileModelCache.dat), separate from
Explorer's iconcache_*.db. ie4uinit and an explorer.exe restart do not touch
it, and they don't recycle the host -- so a rewritten same-name shortcut keeps
showing the first-rendered (often the generic wscript ">") tile until the host
restarts on its own.
Fix: after creating the shortcut, drop only the Start Menu RENDER caches
(TileCache_* + StartUnifiedTileModelCache.dat) and stop StartMenuExperienceHost
(Windows auto-relaunches it), so the tile re-resolves the real icon via the
shell image factory. start2.bin (the user's pinned layout) is deliberately
preserved. Guarded by Test-Path (Windows 10 has no such host -> skipped) and
wrapped in try/catch so it can never fail the install. Windows-only
(install.ps1); no effect on Linux/macOS/Studio.
Verified live: rendering the shortcut via IShellItemImageFactory::GetImage (the
API StartMenuExperienceHost uses) returns the Unsloth sloth icon, color-matched,
after this invalidation -- previously it returned the generic script tile.

WSL) and can never abort the installer.
- scripts/install_rocm_wsl_strixhalo.sh: rewrite to the validated recipe.
Fixes that would have broken a working box: drop the /usr/lib/wsl/lib
preflight (a working ROCDXG host has only d3d12/dxcore there); remove the
obsolete rocr4wsl step (gone from the 7.2.1 repo; would hard-fail and also
rips out the standard hsa-rocr ROCDXG needs); dynamic librocdxg soname
(was hardcoded 1.1.0; build is 1.2.0); direct apt-repo install; Windows
SDK auto-discovery; persist env to /etc/profile.d + ~/.bashrc; idempotent.
- install.sh: _maybe_bootstrap_rocm_wsl auto-offers/runs the helper when it
detects a Strix Halo APU in WSL (/dev/dxg) with no ROCm runtime, then
loads the env so detection routes to the gfx1151 wheels. Fast-path when
already configured. Fix an inaccurate WSL hint line.
- studio/backend/main.py + worker.py: set HSA_ENABLE_DXG_DETECTION=1
in-process before torch (gated on /dev/dxg AND librocdxg.so), so the
worker uses the GPU even when launched outside a login shell. Mirrors the
existing BNB_ROCM_VERSION injection.

* uninstall: clean up ROCm-on-WSL artifacts + Start Menu tile cache
- uninstall.sh: remove the ROCm-on-WSL helper artifacts -- the librocdxg
build clone (~/.unsloth/librocdxg, which otherwise blocks the empty-dir
rmdir of ~/.unsloth), the throwaway smoke-test venv, the persisted env
(/etc/profile.d/unsloth-rocm-wsl.sh) and the ~/.bashrc block. The system
ROCm userspace is a shared prereq like CUDA and is kept by default;
UNSLOTH_UNINSTALL_ROCM=1 removes it too. No-ops on macOS / non-Strix Linux.
- uninstall.ps1: invalidate the Win11 Start Menu tile cache after removing
the shortcut so its tile disappears promptly (mirrors install.ps1),
preserving start2.bin.

* installer: accurate AMD ROCm messaging (HIP SDK optional, not required)
The Windows installer printed "HIP SDK not found - GPU-accelerated training
unavailable" / "ROCm wheels require the HIP SDK" whenever the HIP SDK was
absent. That is misleading: for a detected AMD GPU arch (gfx1151 etc.),
setup.ps1 installs AMD's bundled-runtime ROCm PyTorch wheels (repo.amd.com)
which ship their own ROCm runtime and do NOT need the HIP SDK -- verified
end-to-end (torch 2.11.0+rocm7.13.0, cuda True, QLoRA training on GPU) on a
Radeon 8060S with no HIP SDK installed.
Gate the GPU-detection + rocm-step messages on a detected gfx arch: when one
is known, state that GPU PyTorch uses bundled-runtime wheels and the HIP SDK
is optional; only when the arch is unknown fall back to the HIP-SDK hint.
Behavior (torch routing) is unchanged; this is messaging only. No-op for
NVIDIA/CUDA, HIP-SDK-present, and CPU paths (they hit earlier branches).

* installer: fix /opt/rocm data-loss + make WSL shortcut create/remove interop-robust
Two fixes from the 3-reviewer regression audit + live testing on a
systemd-enabled WSL distro (interop disabled):
F1 (data-loss, install_rocm_wsl_strixhalo.sh): the /opt/rocm symlink-repair
could force-delete a pre-existing REAL ROCm install. The guard only checked
that /opt/rocm is a real directory, not that it is the stray librocdxg stub.
Now it only touches /opt/rocm when it is NOT a real install (no bin/rocminfo,
bin/hipcc, or .info/version present), and MOVES it aside (rocm.unsloth-stub-bak)
instead of deleting it, so a wrong guess can never lose data.
WSL interop robustness (install.sh + uninstall.sh): both relied on
`command -v powershell.exe`, which is true even when WSL interop cannot EXECUTE
it (on systemd distros powershell.exe fails with "Exec format error"). Result:
the WSL shortcut silently failed to create (install) and to remove (uninstall).
- uninstall.sh: test that powershell.exe actually runs; if not, remove the
"Unsloth Studio (WSL...).lnk" files directly via drvfs (/mnt/<drive>), which
works without interop. The name is WSL-install-specific, so a native install's
"Unsloth Studio.lnk" is never touched.
- install.sh: when the shortcut cannot be created, warn with the manual launch
command + how to re-enable interop, instead of failing silently.
No behavior change on the interop-on path. The regression audit otherwise found
no regressions on Linux/Mac/Windows/CPU/NVIDIA install paths.

* install.sh: fast-path fully restores ROCm-on-WSL env when the drop-in is gone
Reinstall regression found by uninstall->reinstall testing: after a Studio
uninstall that removed /etc/profile.d/unsloth-rocm-wsl.sh but KEPT the shared
ROCm (the default), a non-login reinstall hit the bootstrap fast-path
(librocdxg present) and its else-branch only set HSA_ENABLE_DXG_DETECTION --
NOT PATH/LD_LIBRARY_PATH. So rocminfo was not on PATH, GPU detection failed,
and the installer fell back to CPU-only PyTorch.
Fix: when librocdxg is present but the env drop-in is missing, restore the
FULL env inline (HSA + TORCH_ROCM_AOTRITON_ENABLE_EXPERIMENTAL + PATH +
LD_LIBRARY_PATH) so rocminfo is found and detection routes to the GPU, and
recreate /etc/profile.d/unsloth-rocm-wsl.sh so future shells and the Studio
worker get it too. No change to the env-present fast-path or any other host.

* installer: clear Explorer icon cache so shortcut icons aren't blank
Root cause of the persistent blank Desktop + Start Menu icons: Explorer caches
each shortcut's icon in iconcache_*.db and does NOT re-read the .ico when a
same-name .lnk is recreated across reinstalls. The .ico and .lnk are correct
(the shell renders them non-blank via IShellItemImageFactory; the .ico has real
image data at 16/32/48/128 px), but the stale cache entry wins. The previous
fix only ran a weak `ie4uinit -show` + the Start Menu tile-cache clear -- it
never invalidated Explorer's icon cache, so the desktop icon stayed blank.
Fix (native install.ps1 New-StudioShortcuts AND the WSL shortcut path in
install.sh):
- ie4uinit -ClearIconCache (thorough; replaces -show as the primary refresh)
- SHChangeNotify(SHCNE_ASSOCCHANGED) to force a live desktop/taskbar refresh
WITHOUT restarting explorer
- keep the Win11 Start Menu tile-cache invalidation (and add it to the WSL
shortcut path too, preserving start2.bin)
Non-disruptive (no explorer restart). install.ps1 parses clean; install.sh
passes bash -n + dash -n; the heredoc-generated WSL PowerShell parses clean.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* installer: per-item SHChangeNotify(UPDATEITEM) reliably fixes blank icons
The blank Desktop/Start Menu shortcut icons are a stale Explorer PER-ITEM icon
cache: when a same-name .lnk is recreated across reinstalls, Explorer caches the
previously-resolved (often generic "white page") icon for that item and won't
re-extract the .ico on its own. The .ico and the .lnk's IconLocation are correct
(every icon API renders the sloth) -- only Explorer's cached display is stale.
The previous refresh (ie4uinit -ClearIconCache + a GLOBAL SHCNE_ASSOCCHANGED
broadcast) does NOT recover a stale item -- confirmed by reproduction. The
reliable, NON-disruptive fix (no explorer restart) is a PER-ITEM
SHChangeNotify(SHCNE_UPDATEITEM, SHCNF_PATHW, <lnk path>) for each created
shortcut, which forces Explorer to re-read that exact item's icon.
Verified end-to-end: deliberately staled a shortcut to the generic icon, ran the
installer's exact new refresh code, and the sloth icon recovered with NO explorer
restart (confirmed by capturing the live desktop via PrintWindow).
Applied to both native install.ps1 (New-StudioShortcuts) and the WSL shortcut
path in install.sh. Still clears the on-disk icon cache (ie4uinit) and the Win11
Start Menu tile cache (preserving start2.bin).

* uninstall: remove leftover llama.cpp .staging root so ~/.unsloth is cleaned
The llama.cpp atomic-install staging root (install_llama_prebuilt.py
INSTALL_STAGING_ROOT_NAME=.staging) is a sibling of the llama.cpp install
dir (~/.unsloth/.staging in default mode). It is normally pruned after a
successful activate, but an interrupted or retained build can leave a
<name>.staging-XXXX tree behind. The uninstallers removed llama.cpp and
.cache but not .staging, so the final empty-dir cleanup of ~/.unsloth failed
and the directory lingered. Reproduced on WSL (Ubuntu-24.04) where an empty
llama.cpp.staging-XXXX dir kept ~/.unsloth alive after uninstall.
Remove ~/.unsloth/.staging in both uninstall.sh and uninstall.ps1. No-op in
env/custom mode (staging nests under the custom root removed already) and
when absent. Cross-platform fix (the staging logic is platform-agnostic).

* installer: WSL-absent hint + fix here-string lint false positive
install.ps1: in the AMD WSL-ROCm driver hint, detect when wsl.exe is absent
and add a one-line "wsl --install -d Ubuntu-24.04" pointer so a Strix Halo
user with no WSL yet gets an actionable next step (the hint previously assumed
an Ubuntu-24.04 distro already existed). Best-effort, informational only.
test_rocm_support.py: test_no_here_strings did a crude substring check that
false-positived on the conda-style block marker
printf '# <<< Unsloth ROCm-on-WSL (gfx1151) <<<' -- a string literal written
into the /etc/profile.d drop-in, also used as a sed delimiter pair by
uninstall.sh, not a here-string. Strip quoted spans before the check so the
lint still catches a real here-string operator but ignores quoted literals.
install.sh remains POSIX-clean (sh -n / dash -n / bash -n all pass).

* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* installer: address PR review comments (gfx1150 mapping, amd-smi opt-out, WSL bootstrap, SDK path, make)
Apply the valid bot review findings on #5940; reject the ones that don't hold.
Fixed:
- AMD name->gfx table (setup.ps1 + install.ps1): Radeon 890M and Ryzen AI 9 HX
370/375 are Strix POINT (gfx1150), not Strix Halo (gfx1151). Move 890M / HX 37x
/ AI 9 HX to the gfx1150 row and drop the bogus HX 38x pattern (no such Strix
Halo SKU). Matches the runtime classifier in worker.py (890M/880M -> gfx1150;
8060S/8050S -> gfx1151). Prevents Strix Point hosts from getting the wrong ROCm
prebuilt/wheels.
- amd-smi opt-out (setup.ps1 + install.ps1): an explicit UNSLOTH_ENABLE_AMD_SMI=
0/false/no/off now wins over the HIP-SDK heuristic, so a host with a HIP SDK
binary but a broken runtime no longer gets the DiskPart/UAC prompt the opt-out
exists to avoid.
- amd-smi warning probes (install_python_stack.py): _has_rocm_gpu and
_detect_amd_gfx_codes now gate amd-smi behind _amd_smi_allowed() (and pass
_amd_smi_env()), closing the last unguarded amd-smi spawn on Windows.
- WSL ROCm bootstrap (install.sh): the "already-usable ROCm?" early return now
requires rocminfo to enumerate the real gfx1151 agent instead of the generic
_has_amd_rocm_gpu (whose broad gfx[1-9][0-9] match accepts a fallback
"gfx11-generic" ISA), so a Strix Halo box missing the ROCDXG bridge is no longer
skipped. The shared helper is untouched (no gfx90a regression).
- install_rocm_wsl_strixhalo.sh:
* Quote-safe Windows SDK discovery: the old for-in-$(ls -d "...Program Files
(x86)/...") word-split on the space and never matched; use find + read loop.
* Add `make` to apt prereqs (cmake only recommends it; minimal images lacked it
and the librocdxg `make -j` build failed).
* Verification requires gfx1151 exactly (not gfx1[0-9]) so a generic ISA or an
unrelated RDNA GPU can't pass while the real GPU is absent.
Reviewed but NOT changed:
- "Forward inferred ROCm arch without HasROCm" (setup.ps1): already correct --
--rocm-gfx is forwarded under `if ($script:ROCmGfxArch)`, not `if ($HasROCm)`.
- "Route inferred arch into install.ps1 torch path": not a bug -- install.ps1
installs CPU torch as a base by design and setup.ps1 swaps in the ROCm wheel for
the inferred arch (gate `($HasROCm -or $ROCmGfxArch) -and cpu`); verified live
the native install ends on torch 2.11.0+rocm7.13.0.
- "$p null guard after Start-Process" (install.ps1/setup.ps1): redundant -- the
amd-smi runner uses [Process]::Start wrapped in try/catch, so a null process
already returns "" with LASTEXITCODE=1 (no uncaught exception).
- "ls -> find for /usr/lib/wsl/lib" (gemini): stale -- that heuristic was removed;
only a comment about it remains.

* installer(rocm-wsl): auto-install the Windows 11 SDK via winget (fewer manual steps)
librocdxg's build needs the Windows SDK 'shared' headers on the Windows host.
Previously the helper just die()d with "install the Windows 11 SDK and re-run" if
they were missing -- a manual prerequisite that broke the otherwise-seamless
`curl ... install.sh | sh` one-liner on Strix Halo.
Now, when the headers aren't found, the helper installs the Windows 11 SDK on the
Windows host from inside WSL via winget (powershell.exe interop), then
re-discovers them. The SDK installer elevates -> ONE UAC prompt on the Windows
desktop; the headers appear under /mnt/c immediately (drvfs is live, no reboot).
The user already consented to the ROCm-on-WSL setup, so no extra prompt is added
beyond the OS UAC gate.
- New _find_win_sdk (space-safe find of the newest installed SDK 'shared' dir)
and _install_windows_sdk_via_winget helpers.
- winget IDs tried newest-stable first: Microsoft.WindowsSDK.10.0.26100, then
.22621. The presence of the headers (re-check) is the source of truth, not
winget's exit code. </dev/null so winget never consumes a piped `curl|sh` stdin.
- Best-effort + non-fatal: interop-off / no-winget / declined-UAC all fall
through to the existing clear manual-install die(). Opt out with
UNSLOTH_SKIP_WIN_SDK_INSTALL=1.
Removes the last avoidable manual step from the WSL Strix Halo path; only the AMD
Adrenalin driver (AMD referrer-gates the download) remains manual. Verified
_find_win_sdk resolves the spaced "Program Files (x86)" path; bash -n clean; all
winget flags validated against `winget install --help`.

* installer(amd): gate install-time amd-smi probe to fix DiskPart UAC prompt
install_python_stack.py's Windows "AMD GPU detected but ROCm torch missing"
warning probe ran `amd-smi list` whenever amd-smi was on PATH -- and amd-smi
ships in C:\Windows\System32 with the AMD Adrenalin driver -- without the
_amd_smi_allowed() gate that every other amd-smi call site in the file uses.
On Adrenalin-only hosts (no HIP SDK) amd-smi elevates a child at runtime and
pops a UAC/DiskPart prompt that __COMPAT_LAYER=RunAsInvoker cannot suppress
(amd-smi's manifest is asInvoker). The probe also ran before the
ROCm-torch-installed check, so it fired on every Windows AMD install.
Gate it behind _amd_smi_allowed() and pass _amd_smi_env(), matching
_has_rocm_gpu()/_detect_amd_gfx_codes(). When skipped, the only loss is the
best-effort "AMD GPU detected" note on HIP-SDK-less hosts.
Adds a per-function AST regression test asserting every function in
install_python_stack.py that names the amd-smi command and spawns a subprocess
also references _amd_smi_allowed() (flags the pre-fix code; passes after).

* studio(cli): fix `unsloth studio stop` crashing on Windows
`stop` used the POSIX `os.kill(pid, 0)` liveness probe, but on Windows
CPython raises OSError (WinError 87, "The parameter is incorrect") for
*every* pid -- alive or dead. `stop` only catches ProcessLookupError /
PermissionError, so the OSError propagated and the command crashed with
a traceback before ever reaching its (correct) `taskkill /F` path.
Add a cross-platform `_pid_alive(pid)` helper (tasklist on Windows,
signal-0 elsewhere) and use it for both the pre-check and the post-kill
wait loop. The actual kill path is unchanged.
Verified on Windows (Python 3.13): os.kill(pid,0) raises WinError 87 for
both a live and a dead pid; `_pid_alive` returns True/False correctly and
the full stop() flow (alive -> taskkill -> dead -> "stopped") passes
end-to-end against a throwaway process.
Adds tests/studio/test_cli_studio_stop_windows.py (AST guard against a
bare os.kill(pid,0) liveness probe + mock-only _pid_alive behaviour for
the win32 tasklist branch and the POSIX signal-0 branch).

* installer(amd): fix install.sh name->arch table misrouting Strix Point to gfx1151
The bash name->arch inference table in install.sh placed Strix Point
identifiers (Radeon 890M, "Ryzen AI 9 HX 370/375", "AI 9 HX") in the
gfx1151 (Strix Halo) row, diverging from the install.ps1 / setup.ps1
PowerShell tables which correctly map them to gfx1150. It also carried a
stray "HX 38" token absent from the PowerShell source-of-truth.
Align install.sh with the PowerShell tables:
gfx1151 row: 8060S|8050S|8040S|Strix Halo|Ryzen AI Max|AI Max
gfx1150 row: 890M|880M|860M|840M|Strix Point|Krackan|HX 37|AI 9 HX|...
Impact is low (the bash table only feeds the display label _gpu_disp_gfx
and the "set UNSLOTH_ROCM_GFX_ARCH=..." hint; wheel selection is driven
by the detected ROCm version, not this name string) but a Strix Point
user would otherwise see/copy the wrong gfx arch.
Add a parity test (test_install_sh_name_arch_agrees_with_ps_for_strix_and_non_amd)
that parses install.sh's case table and asserts Strix Halo->gfx1151,
Strix Point->gfx1150, RX 7700S->gfx1102, and NVIDIA/Intel->no match,
cross-checking against install.ps1 (the previous parity test only
compared install.ps1 <-> setup.ps1, missing install.sh).

* setup.ps1: keep prebuilt-llama ownership guard within the test's block window
The AMD additions to the prebuilt-llama.cpp block (the windows-hip vs
windows-cpu existing-install kind validation) pushed the
install_llama_prebuilt.py invocation to ~1999 chars after the
"installing prebuilt llama.cpp bundle (preferred path)" anchor, right at
the edge of the 2000-char window that
test_setup_ps1_prebuilt_llama_cpp_has_ownership_guard slices -- so the
helper string was truncated and the test failed with "substring not
found" (CI: Repo tests (CPU)).
The ownership-guard invariant (Assert-StudioOwnedOrAbsent precedes the
install_llama_prebuilt.py call) was already satisfied; only the proximity
to the anchor regressed. Move the "installing prebuilt..." substep to
immediately before the install (after the existing-install pre-cleanup),
which also reads better (validate/clean existing -> then "installing"),
shrinking anchor->helper from 1999 to 413 chars. Behaviour is unchanged
(console message ordering only).

* install.sh: auto-run Strix Halo ROCm-on-WSL setup by default
`curl -fsSL https://unsloth.ai/install.sh | sh` should make a Strix Halo
(gfx1151) GPU usable inside WSL with no extra commands. Previously the
ROCm-on-WSL bootstrap was opt-in: it required UNSLOTH_ROCM_WSL_AUTO=1 or an
interactive [Y/n] at a TTY, and silently skipped under a pipe (no /dev/tty),
so the piped one-liner never set the GPU up automatically.
Flip it to auto-by-default for the single narrow case the existing guards
allow (WSL + Strix Halo + /dev/dxg + no usable ROCm yet) -- exactly the GPU
setup the user ran the installer for. Opt out with
UNSLOTH_SKIP_ROCM_WSL_SETUP=1. The Tauri desktop app keeps its own consent UI
(only auto-runs when it passes UNSLOTH_ROCM_WSL_AUTO=1). All hardware/OS
guards are unchanged, so non-Strix / non-WSL / NVIDIA / native-Linux / macOS /
CPU paths are unaffected.

* PR comments: condense to be succinct (comments/docstrings only)

while preserving every non-obvious "why" (os.kill WinError 87, amd-smi
RunAsInvoker/UAC, /dev/dxg + librocdxg gating, the ROCm-on-WSL bootstrap guard
chain, ownership guards, etc.). No executable code, string literals, messages,
or behavior changed.
Verified comments-only: docstring-normalized AST equality (Python, 9 files),
non-comment token equality (PowerShell, 3 files), comment-stripped diff +
sh -n / bash -n (shell, 3 files). Behavior re-confirmed: get_torch_index_url +
gfx name->arch table 44/44 under dash & bash; rocm_support / pr5940_followups /

* Installer: address PR review (amd-smi opt-out, pipefail, multi-distro, non-root)
Fixes valid findings from the Codex/Gemini PR review:
- install.ps1 / setup.ps1: gate the `amd-smi version` ROCm-version fallback with
$amdSmiAllowed so UNSLOTH_ENABLE_AMD_SMI=0 opt-out is honored (the device
probe was gated but this fallback wasn't), avoiding the DiskPart/UAC prompt.
- install_rocm_wsl_strixhalo.sh: make the post-verification rocminfo summary
best-effort (|| true) so head's early pipe-close under `set -o pipefail` can't
fail the bootstrap after gfx1151 was already enumerated; pin the Windows SDK
`winget install` to --source winget (matches the msstore-cert fix rationale).
- install.ps1: python.org fallback installs the py launcher per-user
(InstallLauncherAllUsers=0, avoids admin), and derives the fallback full
version from the requested minor so a non-default UNSLOTH_PYTHON (e.g. 3.12)
isn't silently replaced with 3.13 when the listing is unreachable.
- install.sh: recreate /etc/profile.d/unsloth-rocm-wsl.sh via `sudo tee` for a
non-root reinstall (a plain redirect failed silently, dropping the ROCm env).
- uninstall.sh: scope WSL Windows-side shortcut removal to the current
WSL_DISTRO_NAME (per-distro name or -d "<distro>" arg) so uninstalling one
distro no longer deletes other distros' launchers.

* Studio ROCm Windows: fix field-reported issues from Strix Halo testers
Four fixes from PR #5940 field reports (Win11 native, gfx1151):
1. bitsandbytes arch-probe spam: bnb's get_rocm_gpu_arch() runs
hipinfo.exe via subprocess PATH at import; the AMD torch wheel ships
hipInfo.exe in the venv Scripts dir, which is only on PATH for
activated venvs. Every bnb import logged "Could not detect ROCm GPU
architecture: [WinError 2]" ERROR + WARNING (even with the HIP SDK
installed, whose bin dir is not on PATH either). Prepend the Scripts
dir to PATH before bnb imports in main.py, worker.py, and
install_python_stack.py, gated on the file existing (only AMD wheels
ship it). Verified on gfx1151: ROCM_GPU_ARCH now resolves to gfx1151
with zero errors.
2. OOM-guard double-tax on native Windows unified APUs: mem_get_info's
total is the WDDM budget the driver grants HIP (BIOS carve + ~half
of remaining RAM) -- the OS share is already outside it. The 0.80
unified cap on top denied loads that fit (field report: 48.49 GiB
budget -> "38.79 GiB allowed" OOM for a 47.29 GiB load with 48.08
free). Use 1.0 on win32 unified; Linux keeps 0.80, discrete 0.90.
3. "Missing VRAM" confusion: log the WDDM budget vs physical RAM with
the fix (BIOS UMA frame buffer / AMD Software Variable Graphics
Memory) when the grant is under 75% of RAM, so a 48 GiB cap on a
96 GiB box reads as policy, not a Studio bug.
4. llama-server fit-step crash (Qwen3.6-27B-MTP + mmproj, lemonade
gfx1151): --fit defaults to 'on' upstream, so the fit step runs even
when Studio already placed the model via -ngl -1, and aborts in
ggml-cuda.cu on some ROCm hosts. Retry the spawn once with --fit off
when the server crashes during startup and Studio's own VRAM math
had placed the model (never when use_fit or an explicit fit flag was
passed). Also keep the TAIL of crash output in the error log (the
diagnostic line prints last; head-truncation cut exactly that) and
reference the full on-disk log.
Verified live on Radeon 8060S: bnb import clean, Qwen3.5-4B-MTP loads
and generates through the new spawn loop, stub-crash retry appends
--fit off and recovers, fraction probes confirm WDDM overcommit and
sub-1.0-only enforcement on current AMD wheels.

* Studio ROCm Windows: GPU-name fallbacks so nothing depends on amd-smi
amd-smi does not reliably exist on Windows: the HIP SDK never ships a
CLI, inbox Windows Update drivers do not, and only some full Adrenalin
packages drop amd-smi.exe into System32 (field report: fresh Win11 +
Adrenalin + HIP SDK, still no amd-smi anywhere). Make every consumer
work without it:
- install_python_stack._detect_windows_gfx_arch: two new probes after
hipinfo/amd-smi -- (2b) the venv Scripts hipInfo.exe shipped by AMD
torch wheels (drives `studio update` on driver-only hosts), and (4) a
last-resort GPU marketing-name -> gfx table via WMI
(Win32_VideoController), mirroring setup.ps1's $nameArchTable so a
standalone repair resolves the arch with zero AMD tooling installed.
- install_llama_prebuilt._resolve_exe: also probe the venv Scripts dir
so a standalone rerun finds hipInfo.exe without HIP_PATH.
- hardware/amd.py _run_amd_smi: which() guard before spawning --
absence now disables the poller in one step instead of burning the
3-strike circuit breaker on FileNotFoundError; corrected the stale
comment claiming Adrenalin ships amd-smi.
Simulated against the real detection functions on gfx1151: amd-smi
absent, present-but-crashing (exit 1), present-but-hanging (60s sleep
vs 5-10s probe timeouts), and hard opt-out -- all resolve gfx1151, no
exceptions, bounded time. Full adversarial install (broken amd-smi
stub first on PATH + UNSLOTH_ENABLE_AMD_SMI=1, fresh uninstall first):
exit 0, name-table arch inference, lemonade gfx1151 b1292 prebuilt,
torch 2.11.0+rocm7.13.0 cuda_avail=True on the 8060S, Studio boots
healthy and stops cleanly.

* Studio: per-attempt llama-server log names + amd-smi test portability
Found by cross-platform simulation of the --fit off retry (Windows +
Linux sandboxes, real load_model with stub servers):
- llama-server log filename now carries the spawn-attempt index. The
retry can respawn within the same epoch second; reusing the name
opened the same file with "w" and truncated the crash log the retry
warning had just pointed the user at (proven with a frozen
time.time: one file, crash evidence gone; with the suffix both
attempts keep their logs). Regression-pinned in
test_llama_cpp_wait_for_health.py.
- test_amd_primary_gpu_with_mock now mocks shutil.which alongside
subprocess.run: the amd-smi absence guard which()-checks before
spawning, so on hosts without a real amd-smi (Linux CI, driver-only
Windows) the subprocess mock was never reached and the test failed.
Surfaced by running the suite in a clean Linux sandbox.
Simulation coverage on both OSes: 67-case platform/edge matrix
(real shipped code blocks under win32/linux/darwin spoofs: OOM-guard
fractions + VGM-hint boundary, bnb PATH-prepend gates, retry
eligibility incl. equals-forms and decoy tokens, GPU-name table
adversarial set, WMI fallback without powershell, monitor absence
semantics), 6-scenario live retry matrix (crash-once/crash-always/
exit-zero/explicit-fit/hang/log-collision) against real llama-server
spawns on Windows and WSL (GPU success legs on the 8060S), and a
3-engine browser matrix (chromium/firefox/webkit) driving the live
backend's health + authed /v1 chat completion.

* Studio: classify unified-memory via props.is_integrated first
Align the ROCm OOM-guard classifier with PR #5988's UMA gate: consult
hipDeviceProp_t.integrated (props.is_integrated) before the hardcoded
arch set. Strictly additive -- truthy upgrades to unified; 0/absent
falls through to the existing gfx1150/gfx1151 + device-name logic, so
wheels that omit or zero the field cannot downgrade the known APU set.
Extends correct unified-cap treatment to APUs outside that set (e.g.
gfx1103 Phoenix iGPUs) and keeps Studio's two unified-memory consumers
on one driver signal. Verified live on gfx1151 (is_integrated == 1 on
the AMD Windows wheel -> ('gfx1151', True) via the new path).
* AMD detection: probe rocminfo with HSA_ENABLE_DXG_DETECTION and sync setup.sh gfx table
Fleet validation on a Strix Halo WSL2 box showed the system rocminfo
(HSA 1.18, ROCm 7.2.1) only enumerates the GPU over /dev/dxg when
HSA_ENABLE_DXG_DETECTION=1, and that rocminfo can sit at /opt/rocm/bin
off PATH outside login shells. Detection probes that miss either of
these report no GPU on a working ROCDXG host and select the CPU build
even though the lemonade bundle offloads fine (95.7 tok/s measured vs
64.5 CPU on the same laptop). Seed the env (a no-op on bare metal) and
the PATH fallback in install.sh, studio/setup.sh, and the installer's
Linux rocm probe, mirroring what main.py/worker.py already do for the
runtime.
Also sync studio/setup.sh's name->gfx table with install.sh: 890M and
the HX 37/AI 9 HX SKUs are Strix Point (gfx1150, not gfx1151), RX 7700S
must match gfx1102 before the gfx1100 row, and the RDNA2/workstation
rows were missing. New parity test pins the two bash tables together so
they cannot drift again.
* Studio: persist server session logs + native-crash stacks to disk
Field report (Strix Halo, 96 GB UMA carve, WSL and native Windows):
"the studio just terminates without a warning". A native crash in the
GPU runtime kills the process with no Python traceback, and a desktop-
shortcut console closes before anything can be read. The server only
ever logged to the console, so there was nothing to send back.
run_server now tees stdout/stderr to
~/.unsloth/studio/logs/server/server-<ts>-pid<n>.log (console behavior
unchanged; file copy is best-effort), arms faulthandler at the same
file so access violations / SIGSEGV leave a stack trace on disk, and
exports PYTHONFAULTHANDLER=1 so training workers inherit crash dumps
on their captured stderr. Armed before `from main import app` so even
import-time failures leave evidence. Keeps the newest 20 session logs;
opt out with UNSLOTH_STUDIO_NO_FILE_LOG=1. Prints "Session log: <path>"
at startup so users know what to attach.
Verified on this box: a forced real segfault (faulthandler._sigsegv)
leaves the full session output plus "Fatal Python error: Segmentation
fault" and the thread stack in the file while the console shows
nothing; a normal server boot captures the startup banner and serves
health as before.

* AMD probe: honor a pre-set HSA_ENABLE_DXG_DETECTION value
Match the shell helpers, which use the parameter-default form: a user
who exports HSA_ENABLE_DXG_DETECTION=0 to deliberately hide the GPU
from DXG detection should not have the probe override it.

* fix(studio): preserve system role in ShareGPT exports
System messages in ShareGPT conversation exports were serialized as
gpt turns, which changes the semantics of exported training data.
Map role system to from system in both the single-thread and bulk
export paths, matching the importer (sharegptToRecords), which
already maps from system back to a system role.
Extracted from #5606 by @LeoBorcherding (commit 7b277913).
* fix(studio): parse quoted newlines when importing conversation CSV
csvToRecords split the file on raw newlines before parsing quotes, so
any exported message containing a newline broke on re-import (the
record was cut mid-field and remainder lines were dropped). The module
already ships an RFC 4180 parser (parseCsv) used by the prompt and
list importers; use it for conversation CSV too.
Multi-line content, embedded quotes and commas, and CRLF files now
round-trip. Unquoted commas in hand-made CSV keep the previous
behavior (rest of line is the content). Flagged in #5606 review as
'Preserve quoted newlines when importing CSV'.
npm 12 (July 2026) stops running dependency install scripts unless they
are approved via allowScripts, and npm 11.16 already warns. Studio has
no git or remote URL deps anywhere, so script gating is the only
exposure:
- commit the allowScripts policy that npm approve-scripts writes for
@biomejs/biome and msw, plus a manual fsevents entry: the tooling
cannot match a darwin-only optional dep from Linux, but the strict
check walks the platform independent ideal tree and flags it anyway
- drop the minimum-release-age npmrc alias; npm >=11.16 flags it as an
unknown project config that stops working in npm 12
- approve bun's postinstall in the setup.sh / setup.ps1 bun bootstrap;
under npm 12 defaults npm install -g bun otherwise leaves a broken
stub and setup falls back to the slower npm install path
- fix the stale esbuild comment in studio-frontend-ci.yml: the vite 8
chain ships napi binaries with no install scripts
* fix: clearer Studio setup error when GPU driver is too old for the installed CUDA toolkit
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Honor optional color arg in setup.sh substep so driver/toolkit warnings render in C_WARN
* Add regression test that setup.sh _cuda_version_gt compares numerically for PR #5993
* Update Resolve-CudaToolkit test for the new driver-too-old messaging
setup.ps1 now routes the too-new-toolkit case through
Write-CudaDriverToolkitMismatch instead of the old 'is installed but
INCOMPATIBLE' banner. Extract that helper alongside Resolve-CudaToolkit so the
child pwsh can run it, and assert the new driver-too-old guidance (and the
one-line source-build error) instead of the removed INCOMPATIBLE text.
* Address review nits: document Windows hard-exit asymmetry and add toolkit/driver edge tests
setup.ps1: note that only a forced source build reaches the hard-exit branch
(the prebuilt path returned above), unlike setup.sh which degrades to CPU.
test_selection_logic.py: cover the CUDA UMD Version variant, the empty nvcc
version guard, and the too_old (< 12.4) short-circuit.
* fix(studio): allow CUDA minor-version compat and try installed toolkits before CPU fallback
The driver check now compares CUDA major versions only, per NVIDIA
minor-version compatibility, and when the selected nvcc is still too
new the setup iterates other installed toolkits and uses the newest
driver-compatible one before falling back to a CPU llama.cpp build.
Same rule mirrored in setup.ps1.
* style: apply ruff kwarg-spacing format after rebase
* Accept a same-major CUDA toolkit found only on PATH in the Windows fallback
The major-only compatibility fix updated the side-by-side scan (Find-Nvcc
-MaxVersion) and the CUDA_PATH check, but the fallback that runs when
Find-Nvcc -MaxVersion returns null still recorded any plain Find-Nvcc result
as an incompatible toolkit without re-checking the major. A same-major
toolkit discoverable only via PATH, process CUDA_PATH, or a custom location
(e.g. toolkit 13.3 with a driver supporting CUDA 13.2) was therefore rejected
even though it is compatible.
Re-apply the same major-only rule in the fallback: use the toolkit when its
major is within the driver's, otherwise record it as too-new. Adds a
regression test covering the PATH-only same-major case.
* Add CUDA driver/toolkit selection edge-case tests for Studio setup

Collapse multi-line comments, drop obvious ones, keep the load-bearing intent
(the major-compat invariant, the Windows hard-exit vs setup.sh-CPU asymmetry,
the PATH-only fallback rationale). Comment-only; no code change.
* Clarify the Windows source-build hard-exit comment
The path is reached by any committed source build (forced, or after a
prebuilt-install failure), not only a forced one. Comment-only.

* fix(studio): block arbitrary external image URLs in markdown renderer
Model-emitted <img src="http://attacker.com/..."> tags were causing the
browser to issue HTTP requests to arbitrary origins, leaking the user's
IP address, User-Agent, and Referer header to any domain a prompt-injected
model could emit (tracking-pixel vector, issue #5596).
Add a urlTransform function passed to <Streamdown> that only allows:
- data: URIs (inline images, mermaid SVG, user attachments)
- blob: URIs (locally generated object URLs)
- relative paths without a scheme (same-origin assets)
All other schemes (http:, https:, ftp:, etc.) return null, causing
Streamdown to omit the <img> element entirely.
Existing iframes are already stripped by Streamdown's default sanitizer;
event-handler attributes (onerror, onload, etc.) are also stripped by
the default schema.
* fix(studio): strip control chars and block backslash URL variants
Two bypass vectors found after review:
1. Backslash-normalised URLs: \\attacker.com\pixel has no colon and does
not start with // so the earlier guards allowed it as a relative path.
Browsers normalise leading backslash pairs to // before resolving, so
the request still reaches the external origin.
2. Embedded control characters: /\n/attacker.com passes trim() unchanged,
startsWith("//") is false, and no-colon check passes it as relative.
Browsers strip ASCII controls (U+0000-U+001F, U+007F) before URL
resolution, so the value resolves to the attacker origin.
Fix: strip all ASCII control characters from the raw URL before any guard,
then block any URL whose normalized form starts with two chars from [/\\]
to cover //, \\, /\, and \/ in one regex.
* fix(studio): delegate non-image URLs to defaultUrlTransform
Returning the raw URL for non-img nodes bypassed Streamdown's built-in
link sanitization, allowing model-emitted javascript: hrefs to reach the
DOM unfiltered. Pass non-image URLs through defaultUrlTransform so the
library's own javascript:/data: sanitization stays active for links.
* fix(studio): use scheme regex instead of includes() for colon check
A colon anywhere in the URL (e.g. /api/image?id=model:v2 or
/snapshots/2026-06-04T12:00:00Z.png) was incorrectly treated as an
explicit scheme and the URL was dropped. Replace the includes(':') check
with a proper scheme regex that only matches when a valid scheme token
appears before any path separator.

* studio(ui): use the --primary brand token for the avatar fallback color
The fallback profile avatar hardcoded #14b789, a slightly different green
from the app's general brand color (--primary = #17b88b, used by the send
button and every other primary-colored control). Next to primary-colored UI
-- e.g. the artifact preview/code panel -- the avatar's off-brand shade looked
inconsistent ("changes color weirdly"). Point avatarBgStyle() at
var(--primary) so the avatar always renders the general brand green and
follows the theme token.
Verified live in Studio: the avatar was rgb(20,183,137) (#14b789) while
--primary resolves to rgb(23,184,139) (#17b88b); the fix unifies them. This
is the only hardcoded brand-green left in the frontend -- every other
brand-green element already uses --primary / bg-primary.

* studio(ui): add literal fallback to the avatar --primary token
UserAvatar is a reusable component; if it is ever rendered outside the theme
root (where --primary is undefined), var(--primary) alone would compute to
transparent. Use var(--primary, #17b88b) so the avatar stays branded in that
edge case. When --primary is defined (the normal case, app-wide) it always
wins, so this changes nothing in practice -- verified in a browser:
var(--primary)=rgb(23,184,139), and an undefined var correctly falls back to
the literal.

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.

Adds the Studio Hub and download manager: browse Hugging Face models and datasets, download GGUF and safetensors with live progress and cancellation, and manage on-device inventory. The Hub does not require a GPU, so it is available on chat-only hosts.
CI: all substantive checks pass, including the three Core jobs after unsloth-zoo#736. The two red checks are non-code flakes, a transient npm-registry DNS resolution failure in the package scan and one quantized vision-model output assertion whose sibling shards passed.

Every transform re-checks the file AST and is dropped if it would differ; the whole-repo reformat is verified AST-identical per file and idempotent.
* Studio: stop leaking internal exceptions to API clients; harden sandbox path
Security hardening for the FastAPI backend.
Error exposure (CodeQL py/stack-trace-exposure): many route handlers returned
raw caught-exception text to clients via HTTPException detail / response bodies,
which can leak internal filesystem paths and stack detail. Add shared helpers in
utils/utils.py (safe_error_detail, log_and_http_error) that log the full
exception server-side and return a generic message, and sweep the route layer
(inference, models, export, training, datasets, chat_history, providers,
mcp_servers, settings, data_recipe/{jobs,seed,validate,mcp}) to use them.
Intentionally user-facing validation messages, the existing _friendly_error SSE
paths, and upstream-service body passthrough (llama-server / OpenAI) are kept;
absolute server paths echoed in models.py browse/read errors are redacted.
Path injection (CodeQL py/path-injection): serve_sandbox_file already does
basename + realpath containment; add a strict filename allowlist
(^[A-Za-z0-9._-]{1,255}$) before the path is built as defense-in-depth and to
give the analyzer a clear sanitizer.
No behavior change beyond error-message text; status codes preserved.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Address review: keep curated error messages, fix remaining load leak
- inference.py /load non-native path: redact str(e) instead of leaking it
(matched the native branch which already redacted).
- llama_extra_args validation: return the curated, path-redacted message
instead of the generic fallback so users see the offending flag.
- sandbox file serving: allowlist now forbids only separators/control chars
via fullmatch, so generated images like 'loss curve.png' render again
while traversal is still blocked by basename + extension + realpath.
- Add safe_curated_detail() for domain/validation exceptions whose message
is intentionally user-facing; apply it to data_recipe job/validate,
chat conflict, provider test, and MCP probe paths (these were collapsing
to 'An internal error occurred', and 'connection' even mis-mapped to an
upstream-service message). Generic Exception paths keep safe_error_detail.
- log_and_http_error: tolerate stdlib loggers (no structlog kwargs).
- delete_openai_container: log transport errors with exc_info like list/create.

* Studio: keep chat in place when composer attachments resize it
Attaching or removing a file in the chat composer could yank the whole
conversation to the bottom, and the grown composer covered the end of
the chat with no way to scroll it back into view.
Root cause: the Viewport composes refs with an identity that changes on
re-render, so React re-runs our scroll ref on unrelated renders and the
autoscroll hook treated every rebind as a fresh mount, pinning to the
bottom. On top of that the viewport reserved a fixed 160px under the
last message regardless of composer size.
- Treat same-element ref rebinds as no-ops in the autoscroll hook; only
a genuinely new viewport element pins and resets detach state
- Size the bottom spacer from the measured composer height plus a 24px
gap so the chat can always be scrolled above the composer
- On composer growth, detach from the bottom instead of auto-scrolling;
the user scrolls down to reveal the covered lines
- On composer shrink, defer the spacer shrink until it cannot clamp
scrollTop, then release it invisibly on scroll or on bottom-pinning
moments (run start, thread switch, thread load)
* Studio: release deferred composer spacer when a run owns the bottom
Sending with attachments cleared the chips after thread.runStart had
already fired, so the spacer shrink was deferred while the user sat
pinned at the bottom, leaving a permanent extra gap above the composer.
Apply shrinks immediately while a run is active or within 1s of run
start; the run-start pin owns the bottom then, so the clamp is the
intended glide. Caught by a cross-engine Playwright pass (Chromium,
Firefox, WebKit) over the pre and post builds.
* Studio: track the viewport element in state so listeners survive remounts
The deferred-shrink scroll listener was attached once against a ref, but
the keyed overlay provider remounts the viewport subtree on thread
switches, leaving the listener bound to the unmounted element. Removing
an attachment near the bottom in the new thread then left the oversized
spacer stuck until a run started. Track the viewport element in state so
the listener and the clamp math follow the new element.
Reproduced and verified with a thread-switch scenario on Chromium,
Firefox and WebKit; full matrix re-run green.

Asserts ChatInferenceSettings declares every InferenceParams field the
frontend persists (all but checkpoint). With extra="forbid", a field
present in the UI but missing here 400s PUT /api/chat/settings, which is
exactly how fastMode regressed. Catches the next occurrence at CI time.

* fix: warn when localhost resolves to ::1 but Studio is bound only to 127.0.0.1
* studio: fix localhost/::1 warning suppression and cover _run wiring
Addresses the Codex review on #5994 plus review-team findings:
- Remove the `_local_port_open("::1", port)` early-return. Studio binds
127.0.0.1 only, so a successful connect to ::1:<port> means a *different*
process is there -- exactly when http://localhost opens the wrong service
and the user most needs the warning. Dropping the probe also removes the
~0.25s startup latency and the probe/warn race.
- Extract the banner/warning block from `_run` into `_emit_startup_output`
so the wiring is unit-testable, and make the mismatch vs wildcard paths
an explicit if/elif (they are mutually exclusive by construction).
- Hoist the `_working_local_url` confirmation out of the try block and
reorder `_stdout_color_ok` before its only caller.
- Tests: add `_emit_startup_output` integration coverage (banner
include_stop_hint, warning emission, single stop hint), a regression test
that ::1 being occupied does NOT suppress the warning, dual-stack and
non-positive-port cases; drop the unreachable `None` getaddrinfo arm.

* Studio: refine tool call and reasoning trigger UI
Tool call triggers:
- Chevron fades in on hover or keyboard focus and sits next to the
label instead of being pinned to the right edge, matching the other
collapsible triggers.
- Labels wrap instead of truncating so long tool names and search
queries stay fully readable.
- Smaller chevron for a lighter look.
Reasoning trigger:
- Smaller chevron to match.
- Thinking box drops its bottom padding and raises the streaming max
height so more of the thinking text is visible.
* Studio: pointer cursors and sidebar 3-dots polish
Collapsible triggers:
- Pointer cursor on the reasoning, tool call, and tool group triggers
so they read as clickable.
Chat sidebar:
- Swap the chat row 3-dots menu to the vertical more-vertical icon.
- Pointer cursor on the chat row and its menu button.
- Chat row right padding opens up on hover (pr-4 at rest, pr-8 on
hover) so the title keeps a comfortable gap and clears the menu.
* studio: refine tool-call spinner, chevron, and reasoning spacing
- Use the lucide arc spinner for running tool calls and the app-wide
Spinner, so loading states match the rest of the UI.
- Collapse long tool-call labels to a single line with an ellipsis,
reveal the full label when the row is expanded, and fix the clipped
descenders.
- Keep the collapse chevron next to the label and add top spacing above
the reasoning trigger.
- Remove the redundant nested spinner in the web search running state.
* Studio: drop tool call group background fill
The ghost tool call group used a translucent bg-muted/10 fill that read
as a faint lighter box around every group in dark mode. Remove the fill
and rounding so the group sits flush on the chat background.

The composer dock backdrop was a solid block with a hard top edge, so
chat text scrolling underneath got visibly clipped. Replace it with a
gradient that fades the top 28px to transparent.
Also shorten the plus to x rotation in the composer from 300ms to 250ms,
including the reduced motion override.
* Studio: enable audio input for Gemma 4 GGUF models
Audio file upload was disabled for Gemma 4 vision+audio GGUFs (e.g.
gemma-4-12b-it-GGUF) even though their mmproj carries an audio encoder
(clip.has_audio_encoder, gemma4ua). Two causes:
- Audio-input detection only matched Gemma 3n's <audio_soft_token>;
Gemma 4 uses <|audio|>, so audio_vlm was never detected.
- The GGUF load/status responses hardcoded has_audio_input=False, so the
flag was dropped even when audio_vlm was detected (affected Gemma 3n
GGUFs too).
Changes:
- Recognize <|audio|> alongside <audio_soft_token> in the llama-server
token probe and the tokenizer-config pattern.
- Read clip.has_audio_encoder from the mmproj as an independent,
model-agnostic signal (read_mmproj_audio_capability).
- Emit the computed has_audio_input on the GGUF load/status responses.
- Tests for the new pattern and the mmproj reader.
* Studio: default chat model and dataset helper to Qwen3.5-4B-MTP
Switch the auto-loaded chat default and the dataset-analysis helper GGUF
from gemma-4-E2B-it to unsloth/Qwen3.5-4B-MTP-GGUF (UD-Q4_K_XL).

Addresses review feedback on #5971. _reset_password_command() already
shell-quotes the launcher path on POSIX (shlex.quote), so wrapping the result in
another pair of single quotes in the error string produced a mangled hint for
installs / home dirs containing spaces, e.g.
Run ''/tmp/Unsloth Studio/.../unsloth' studio reset-password' in your terminal
which a shell mis-parses. Drop the outer quotes and put the command at the end of
the message so it is unambiguous and copy-pasteable in every case:
Incorrect password. To reset it, run this in your terminal: <cmd>

* studio: redesign chat composer
Reworks the new-chat composer and the compare composer into a single
rounded pill surface with a softer, lighter look.
- New welcome screen with a time-of-day sloth mascot and a lighter
heading.
- One rounded composer surface with a soft drop shadow. The input grows
inline as you type and collapses back to a single row when cleared.
- Tools and attachments live in a single plus menu; the thinking control
is a compact pill with a reasoning-effort submenu.
- Inlined glyphs for the thinking, send, and dictate controls, kept in
sync across the main and compare composers.
- Toast notifications match the composer surface: no border line, the
same drop shadow, and the same dark surface color, with a ring-less
close button.
- Dark mode: the side-menu shadow blends into the background, hovered
menu rows read clearly, and their roundness matches light mode.
- Composer styles use dedicated unsloth- prefixed classes so compare
mode keeps its own stacked layout.
* studio: sync compare-composer reasoning state and harden compare id
- Compare composer: keep "Preserve thinking" consistent with reasoning,
matching the main composer. Enabling it now turns reasoning on, and
disabling reasoning (the None option or the Thinking toggle) turns it
off, so the invalid "preserve on while thinking off" state can't occur.
- Guard crypto.randomUUID in the Compare action. It is undefined in
non-secure contexts (HTTP over a LAN IP) and would throw; fall back to
a timestamped random id, matching createNavigationNonce.
* studio: reflect pre-selected Search/Code tools when no model is loaded
The Search and Code pills only lit up when the tool was usable right now
(a model loaded and capable), so a tool turned on from the + menu showed
as off in the pill while the menu showed it on. toolsEnabled is persisted
and takes effect once a capable model loads, so the pill should reflect it.
The pills now disable only when a loaded model lacks the capability, and
otherwise reflect the selected state. Applied to the main and compare
composers.
* Studio: link MCP Servers heading to its PR and fix composer pill cursors
Make the "MCP Servers" heading in the chat Configuration sheet link to the
MCP PR, keeping the chevron as the toggle. The label and chevron are rendered
as siblings so we don't nest an <a> inside a <button>.
Also add cursor-pointer to the composer pills and the thinking pill so hovering
a clickable pill shows the hand cursor instead of the default arrow.
* Studio: refine chat composer and add compare-mode parity
- Composer expands to two rows only once the input wraps to a second line,
not on the first keystroke. Re-measure the autosize textarea on the width
swap so expanding no longer leaves a stray blank row.
- Light-mode composer shadow now matches Gemini's soft elevation.
- Plus menu: replace Canvas with a More submenu (Canvas, Compare chat, RAG)
and add Code above MCP. Active Web search/Code items use medium weight.
- Compare mode: the plus side menu, Search/Code toggles, and a Compare exit
pill now match single chat, with the thinking control on the right.
- Projects menu entries link to their tracking PR (#5725).
- Add cursor-pointer to the composer plus button.
* studio: refine composer controls and chat search shadow
- Active tool pills show an x on hover to signal click-to-disable
- Plus button rotates into an x when the tools menu opens
- Composer surface uses a 32px radius and a taller single-line height
- Even, ChatGPT-style spacing between the plus and tool pills in both the single and compare composers
- Send and mic circles resized and spaced, with the arrow centered in the circle
- Chat search box gets a borderless, soft Gemini-style shadow
* studio: size the pill hover x to match the icon it replaces
Cross-engine checks (Chromium, Firefox, WebKit) flagged the active-pill
hover x as a fixed 14px, so it popped smaller than the 19px Code icon.
Fill the glyph slot instead so the x tracks whatever icon it covers.
* studio: do not persist Kimi search/thinking mutual-exclusion in single composer
The single-chat composer flipped the other control off when toggling
search or thinking on Kimi, but without { persist: false }, so it
overwrote the user's saved preference. Match shared-composer and keep
the side effect session-only.
* studio: pointer cursor on model selector trigger and menu items
Add scoped marker classes so the model picker trigger and every
clickable element in its menu (tabs, model rows, delete, eject) show a
pointer cursor; disabled items stay not-allowed.
* studio: pass baseUrl when resolving reasoning caps in single composer
The docked composer omitted baseUrl, so a custom Gemini OpenAI-compat
gateway still advertised the native thinking ladder the backend cannot
honor. Pass selectedExternalProvider.baseUrl like the compare composer
so the resolver hides it.
* studio: grey side-menu hover, green pill hover, thinking hover x
- Plus side-menu items hover grey in light mode, not the green accent
- Thinking pill hovers green like the Search and Code pills
- The plain Thinking toggle shows an x on hover when active, matching
Search and Code; the effort dropdown trigger keeps its bulb
* studio: make the pill hover x a uniform size
The x filled the icon slot, so the wider Code chevron gave a bigger x
than Search and Compare. Pin it to a fixed 15px, centered, so every
pill's x matches.
* studio: broaden chat attachments, fix active hover color, gemini shadow
- Accept svg, source code and many text/config files as drag-and-drop
or picked attachments, matched by extension since their MIME is
unreliable; html keeps its own adapter
- Active (green) side-menu items keep their text and icon color on
hover instead of switching to the accent color
- Composer surface uses Gemini's soft centered shadow 0 0 20px rgba(0,0,0,0.04)
* studio: keep the thinking pill full height when icon-only
The inactive thinking pill has no label, so its flex row collapsed to
the icon height and the hover box looked short. Reserve one text line
(min-height: 1lh + padding) so it matches the Search and Code pills.
* studio: refine composer menu, drop overlay and greetings
- Open the MCP servers dialog directly from the composer plus menu
- Redesign the drag-and-drop affordance Gemini style, drop the badge and border, make the whole chat page a drop target
- Swap in Hugeicons for the RAG, attachment chip and new project icons
- Add time-based randomized welcome greetings, each matched to a fitting sloth
* studio: rename artifacts toggle to Canvas and make it opt-in
- Label the toggle Canvas everywhere, matching the plus menu
- Stop greying out the Canvas menu item; it toggles like the other items
- Only show the Canvas pill in the composer row once it is turned on, since it is less central than Search and Code
* studio: wire Canvas and MCP composer toggles, even out the pill row
- Open the MCP servers dialog from the menu, or toggle MCP on/off once a server is enabled
- Force MCP off when no server is enabled, so the toggle stays honest
- Show Canvas and MCP as opt-in pills that appear in the order they were toggled on
- Expand the composer and light up the pill when Canvas or MCP is on, like Search and Code
- Keep Compare directly after Code in the compare composer
- Use the same Code icon on both composers and give every pill an even icon slot
* studio: tidy composer toggle row and fix MCP enable/disable lifecycle
- Enable MCP automatically after a server is configured via the toggle flow
- Force MCP off everywhere once the last enabled server is removed
- Collapse the pill labels to icons only when more than 4 pills show, keeping Compare labelled
- Order Compare first in compare mode, before Search and Code
- Use the same Code icon and an even 19px icon slot across both composers
- Match the compare composer surface padding and send button inset to normal chat
* studio: revert compare composer padding change that cramped the input
Matching the surface padding to normal chat clipped the textarea text and
left a white strip on top. Restore the compare composer's own padding, which
gives proper top spacing. The send button inset fix stays.
* studio: center welcome greeting and soften composer scrollbar
Center the sloth and title together over the composer instead of
shifting the row left, which left the greeting sitting off to the side.
Keep the composer textarea scroll thumb faint by default and only darken
it when the thumb is hovered or dragged, so a tall draft no longer shows
a heavy dark rail.
* studio: match composer plus-menu tool gating to the pills
The new plus-menu tool entries did not carry the gating the visible pills
already enforce, so the menu and pills could disagree about a loaded
model's capabilities.
- Web search and Code menu items now disable when a loaded model lacks
the capability, while still allowing preselection with no model loaded.
- Enabling Web search from the menu on a Kimi model now flips thinking
off as a session-only change, since Kimi forbids search and thinking
together. This matches the Search pill.
- Added an Images menu item, shown only for image-generation models and
disabled until a model loads, so a short prompt has an entry point.
Applied to both the single-chat and compare composers.
* studio: round the active-pill hover x and even out pill padding
The hover x sat bare and the trailing label was tighter to the pill edge
than the leading icon, so the pill looked lopsided.
- Give the hover x a soft circular background that fills the icon slot,
matching the ChatGPT-style toggle and the icon it replaces.
- Add a little more trailing padding so the label and the leading icon
have even breathing room, and keep icon-only compact pills symmetric.
* studio: nudge the thinking bulb icon up by 0.5px
Bump the thinking lightbulb from 15px to 15.5px in the single-chat and
compare composers so it sits a touch larger next to the other controls.
* studio: drop the hover x circle on icon-only pills
When pills collapse to icon-only, the circle around the hover x is too
cramped in the small chip, so show a bare x there and keep the circle
only on the full-width labelled pills.
* studio: space the compare send button like normal chat
In compare mode the Thinking control sat right against the send button.
Match the normal composer's control spacing (gap-1.5 plus a send margin)
so Thinking has the same breathing room before send. The send button
keeps its 14px inset, so its position is unchanged.
* studio: make collapsed pill hover a circle, not a wide pill
Icon-only pills were wider than tall, so their rounded-full hover
highlight read as a fat rounded rectangle. Make the compact button a
square and center the glyph so the hover (and the x it reveals) sits in
a clean circle.
* studio: fix compare pane drops and audio picker lifetime
- Skip the page-level drop handler when the composer is hidden, so files
dropped on a compare pane are not swallowed by a hidden composer; the
shared compare composer keeps handling drops through its own dropzone.
- Build the audio file input on document.body instead of inside the plus
menu, so the menu closing on select no longer unmounts the input before
the OS picker returns and drops the file.
* studio/chat: stop projects list from white-screening on older backends
The projects list API returned data.projects directly, so a backend that
omits the field handed back undefined. useChatProjects cached that value,
then the next mount read undefined.length and crashed the whole chat page.
Default the projects and threads list APIs to an empty array and keep the
hook null-safe so a bad response can never poison the cache.
* studio/chat: align MCP dropdown with the + menu and add a chevron
Reuse the + menu surface (unsloth-plus-menu) for the MCP dropdown: rounded
corners, narrower width, neutral grey hover, and enabled rows shown as green
text with a right-aligned check instead of the emerald underlay. Add a
chevron to the MCP pill so it reads as openable, matching the Thinking pill.
* studio/chat: make MCP an opt-in pill and fix its dropdown placement
- MCP is back in the + menu as a toggle. The pill now only shows in the
composer when MCP is on, matching Canvas, instead of always sitting there.
- The dropdown follows the composer side like the + menu (opens down in the
welcome composer, up when docked) rather than always opening upward.
- Drop the dropdown caret when pills collapse so the icon is not squished.
- Stop force-syncing mcpEnabledForChat to the server count; the + menu owns it.
* studio/chat: MCP expands the composer, drop sidebar Compare, tidy scrollbars
- Toggling MCP now expands the composer and shows the tool pills, the same as
Canvas, instead of leaving the row collapsed.
- Remove the Compare item from the sidebar now that it lives in the + menu, and
point the compare tour step at the side-by-side view instead of the old button.
- Both sidebars only show their scrollbar on hover, and run settings reserves
the scrollbar gutter so the close button no longer shifts when it appears.
* studio/chat: tighten toggle gap, fix run-settings close button, collapsed Train
- Reduce the composer toggle gap by 2px (gap-1 to gap-0.5) in both composers.
- Move the run settings header out of the scroll area so the close button keeps
its position whether or not the scrollbar shows, and sits flush with the
topbar open button again instead of shifting left.
- Surface Train as an icon in the collapsed sidebar (it already has a labelled
section when expanded).
* studio/chat: tighten Thinking pill X padding, create projects inline
- The Thinking pill used px-2.5, so the hover X sat further in than the left
pills. Match their pl-2 so the X lines up.
- The + menu New project now opens a create dialog and jumps straight to the
new project, instead of routing to the projects list. Shared by both
composers via a small NewProjectDialog.
* studio/chat: soften account menu, hover scrollbars, show collapsed chevrons
- Account menu drops its border ring for the composer's soft shadow and opens
centered over its trigger.
- Settings and search reuse the hover-only scrollbar via a shared
hover-scrollbar class, matching the sidebars.
- Train and Recents keep their chevron visible while collapsed so it is clear
they can be expanded.
* studio/chat: roomier, more rounded account menu
Widen the account menu, add more left and right padding on the rows, bump the
row height and text a touch, and round the corners more, closer to the GPT
account menu.
* studio/chat: trim account menu width and nudge it up 2px
Pull the account menu in slightly on the left and right (narrower box, a touch
less row padding) and lift it 2px higher above the trigger.
* studio/settings: drop outline ring, circular close hover, pointer cursors
- Remove the settings dialog outline ring, keeping just the soft shadow.
- The close button hover is now a circle instead of a rounded rectangle.
- Every clickable control in the settings dialog uses a pointer cursor.
* studio/chat: bump MCP pill icon to 14.5px
Nudge the MCP icon up 0.5px so it sits even with the other pill glyphs.
* studio/chat: bump MCP pill icon to 15px
Nudge the MCP icon up another 0.5px.
* studio/settings: add a Settings title above the tabs
Put a Settings heading at the top of the sidebar so the tabs sit below it,
matching the Claude settings layout. Hidden on mobile where the nav is a row.
* studio/settings: rounder tab hover, bigger title, less-round search dialog
* studio/sidebar: round nav row hover boxes 2px more (10px to 12px)
* studio: drop settings dark shadow + divider, add tab left padding, tune hover roundness
* studio/model-selector: roomier padding, borderless box, rounder hover rows; settings divider light-only
* studio/search: match chat box shadow (soft light, none dark)
* studio/sidebar: borderless chat context menus, rename submenu to Projects with folder-export icon
* studio/model-selector: match light corner radius in dark, drop dark shadow, more visible dark hover
* studio/sidebar: chat context menu matches + side menu styling; relabel submenu Move to project
* studio: borderless message export menu (no dark shadow), match dark corner radius to light on export menu and settings
* studio/sidebar: open chat options menu GPT-style (down-right) and widen so Move to project fits one line
* studio/chat: message export menu uses the chatbox shadow in light mode
* studio/sidebar: narrow chat options menu slightly (w-60 to w-56)
* studio: unify all download icons to Hugeicons download-01; round profile button hover 1px more
* studio/run-settings: bump header to 16px
* studio/sidebar: trim chat options menu width slightly (w-56 to 216px)
* studio/sidebar: trim chat options menu width to w-52
* studio/profile: camera-01 Hugeicons glyph and chatbox shadow on avatar button
* studio: match dark-mode corner radius to light globally (single --radius token)
* studio/recipes: borderless New Recipe menu with chatbox shadow in light, none in dark
* studio: borderless dropdowns globally, chatbox shadow in light, none in dark
* studio: extend borderless + chatbox/none shadow to select, combobox and popover overlays
* studio/mcp: nudge MCP dropdown radius to 20px so its wider box reads as round as the + menu
* studio: restore dark dropdown shadow to avoid same-color merge; greet name ~1/3 of lines; bigger sloth + more gap
* studio/train: active tab is a borderless pill (no underline), roomier padding, more tab gap and bottom spacing
* studio/chat: nudge welcome up ~5px (still vh-based) and trim sloth image to 44px
* studio/train: active tab pill is white with chatbox shadow in light, taller padding
* studio/chat: welcome offset to calc(30vh - 10px)
* studio/chat: welcome offset to 28vh (drop the -10px)
* studio/chat: tighten sloth-to-text gap by 1px (16px to 15px)
* studio/train: revert light active pill to grey fill, drop white bg + shadow
* studio: app-wide hand cursor on every clickable control (disabled excluded)
* studio/chat: welcome offset to 26vh
* studio/chat: welcome offset to 28vh
* studio/chat: harden project and thread list guards against non-array payloads
* studio/sidebar: give the profile row more height and breathing room
* studio/sidebar: trim the profile row top and bottom padding slightly
* studio/sidebar: reduce Train and Recents section label size slightly
* studio/sidebar: trim the profile row top and bottom padding a touch more
* studio/sidebar: enlarge the profile hover area top and bottom
* studio/sidebar: increase profile hover roundness by 1px
* studio/sidebar: trim the profile row top and bottom padding slightly
* studio/sidebar: trim the profile row top and bottom padding slightly
* studio/chat: cache composer line metrics so wrap detection runs once, not per keystroke
* studio/chat: restore the prior view when exiting compare opened from the + menu
* studio/tests: drive Compare from the composer + menu after it moved out of the sidebar
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* studio/tests: open Compare from the composer + menu in the extra UI suite too
* studio: fix chat dictation microphone access
* studio: snappier plus-to-x spin and steady composer expand gap
Speed up the composer plus icon morph from 480ms to 300ms.
Add row-gap on the expanded composer line so the space between the text
and the controls row stays the same whether the box expanded from
wrapped text or from a toggle being on. The gap sits on the line, not the
input, so the placeholder max-height clamp never crops it.
* studio: only show composer tool pills once a model is loaded
Persisted Search/Code/Canvas/MCP toggles were surfacing the composer pill row on a fresh page load before any model was selected, so an empty composer looked different from the clean just-ejected state. Gate the composerExpanded tool checks on modelLoaded so a model-less composer stays collapsed, while saved preferences still apply the moment a model loads.
* studio: hide RAG composer menu item temporarily
Hide the placeholder RAG entry from the composer plus menu in both single chat and compare until the feature is ready, and drop the now-unused DatabaseIcon import.
* studio: let composer tools pre-select before a model loads
Selecting Web search, Code, Canvas or MCP from the + menu with no model
loaded did nothing visible: the toggle turned on but the composer never
expanded, so the pill stayed hidden. Drop the model-loaded gate from the
expand check so an active tool always surfaces its pill.
Align MCP with the Search/Code pattern too: grey it out only when a loaded
model lacks tool support, so MCP stays toggleable and the pill stays
clickable before a model is loaded instead of looking disabled.

* Update Install Scripts
Add SPDX AGPL-3.0 headers to the installer scripts and let the piped web
installs take their common options from the environment.
- install.sh / install.ps1: read UNSLOTH_NO_TORCH (and UNSLOTH_PYTHON for
install.sh) so a piped install needs no positional flags. Flags and the
pipe forms still work; an explicit flag wins.
- Fix the UNSLOTH_STUDIO_HOME example so the variable sits after the pipe
and reaches sh instead of curl.
- Add SPDX headers to install.sh, install.ps1, the uninstall scripts, and
the MLX install scripts.
- Drop the internal test package names from the studio install comments.
* Mirror UNSLOTH_PYTHON env var to install.ps1
install.ps1 now reads UNSLOTH_PYTHON to pin the Python version, matching
install.sh, and lists all three env vars (UNSLOTH_NO_TORCH, UNSLOTH_PYTHON,
UNSLOTH_STUDIO_HOME) in the header examples. The requested version is
preferred during detection and used as the winget install target; behavior
is unchanged when the variable is unset.
The Studio login error rewrote the backend's PATH-based command into a relative Windows path (.\unsloth_studio\Scripts\unsloth.exe ...) that only resolves from inside the Studio home dir and fails with CommandNotFoundException elsewhere. Removes the Windows-only rewrite and the now-unused usePlatformStore import so the backend's unsloth studio reset-password command is shown as-is on all platforms.
Clears the safe set of Dependabot advisories.
Frontend (overrides, all transitive; npm audit now 0):

ip-address 10.1.0->10.1.1 (also clears express-rate-limit), and
brace-expansion 5.0.5->5.0.6 (scoped, the 1.1.14 line is untouched).
Desktop: tauri 2.10.3->2.11.1, pulling the runtime crates it requires

is 5.0.0rc3), sqlfluff (major 3->4), glib/rand (stack-coupled transitive).
Fixes#5572. Replaces cmdk's default fuzzy filter with a strict substring-token filter so threads that do not match the query are hidden and the empty state shows. Each item uses its unique thread id as the cmdk value, with the searchable title and preview supplied via keywords.
Adds studio/backend/utils/datasets/dataset_none_detect.py, a standalone scanner that reports None/empty content turns in alpaca, chatml, sharegpt, and gptoss datasets without modifying data, plus generator and runner scripts under tests/utils. Depends only on the datasets library and is not wired into the package init, so it stays import-light.
