Source llama.cpp prebuilts from unslothai/llama.cpp (CUDA, ROCm, macOS) (#5963)
* Studio: route arm64 Linux CUDA hosts to linux-arm64-cuda prebuilts

* Studio: SM-aware selection for windows-cuda app bundles

* Studio: select published ROCm bundles by gfx target (linux + windows)

* Studio: route macOS installs to the fork's prebuilt bundles

* Studio: fix windows cuda13 driver-13.0 gate and ROCm gfx prefix overreach

* Fix Blackwell Windows pin shadowing native app-bundle (b9360 over b9457)

* Match Windows cuda12 driver floor to Linux (12.x minor-version compat)

* Fix Windows app-bundle dropped when runtime DLLs come from torch/lib

* Fold the manifest resolver into the simple-path resolver (one entry, no dormant full path)

* Remove unused UNSLOTH_LLAMA_PUBLISHED_REPO override

* Route Windows GPU hosts to the fork prebuilts in setup.ps1

* Document sm_103 path divergence and mark --simple-policy as a no-op

* Note sm_103 coverage now comes from the producer manifest

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Remove the now-vestigial --simple-policy flag (one resolver handles all hosts)

* Unify the fork onto the manifest path; drop the linux-x64 filename path and hardcoded coverage tables

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Strip whitespace from manifest gfx_target/mapped_targets when parsing

* Windows CUDA: sort coverage-unknown bundles last so they can't outrank targeted ones

* Share the SM-coverage sort key between the linux and windows selectors via _sm_range

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Studio: reject approved releases with an exact source archive but no source repo to clone from

* Studio: accept the fork's windows-rocm kind in the Windows reinstall check

* Studio: accept a manifest-bundle source repo in the exact-source release check

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Studio: route Linux hosts to the fork only when a usable GPU is present

* Fix Windows AMD lemonade tag resolution for PR #5963

The fork release scan passes each scanned release's upstream tag
(b9518, ...) to the lemonade lookup, but lemonade publishes its own tag
series (b1292, ...) that never contains upstream tag numbers. On a
Windows AMD host every scanned release therefore 404s the lemonade
fetch twice, the upstream HIP zip is dropped by the approved-hash gate,
and the scan walks the whole release history until it dies on the
unauthenticated GitHub rate limit or falls to a HIP source build. The
Linux path already passes the requested tag ("latest") and works.

Thread the requested tag through resolve_release_asset_choice ->
resolve_asset_choice -> resolve_upstream_asset_choice as lemonade_tag,
used only by the lemonade lookups. Upstream asset names keep the
concrete per-release tag and all new parameters default to the old
behavior.

Verified on a gfx1151 box: before, the native Windows install scanned
b9518..b8811 and aborted on rate limit; after, it selects
llama-b1292-windows-rocm-gfx1151-x64.zip (lemonade) from fork release
b9518, passes staged validation, and the installed llama-server
enumerates ROCm0. WSL keeps selecting the matching ubuntu bundle.
Adds a regression test pinning that the Windows fork path resolves
lemonade via /releases/latest, never /releases/tags/<fork-tag>.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Plan lemonade for Linux ROCm hosts on the ggml-org direct path for PR #5963

Audit follow-up to 72f32364 across the other selection pathways. The
ggml-org direct planner kept its lemonade attempt for Windows ROCm
hosts but planned only the CPU tarball for Linux ROCm hosts, so an AMD
Linux box routed to ggml-org (for example a --published-repo override)
silently installed the CPU build. That lemonade planning used to live
in the --simple-policy dispatcher this PR removed.

Add the lemonade attempt ahead of the CPU tarball in the Linux x86_64
branch, mirroring the Windows branch, with the lookup keyed to the
requested tag. Adds a regression test asserting lemonade is the first
attempt for a Linux ROCm host on the direct path.

Also re-verified the other pathways on a gfx1151 box: the fork-routed
flows pass the requested tag everywhere, repeat runs over an existing
lemonade install correctly skip with "already matches selected release
b9518" on both native Windows and WSL, and macOS, CUDA and CPU
selection are untouched. Suites: 328 passed on Linux, Windows matches
the pre-existing baseline.

📥 Advanced Installation

The below advanced instructions are for Unsloth Studio. For Unsloth Core advanced installation, view our docs.

Developer installs: macOS, Linux, WSL:

git clone https://github.com/unslothai/unsloth
cd unsloth
./install.sh --local
unsloth studio -p 8888

Then to update :

cd unsloth && git pull
./install.sh --local
unsloth studio -p 8888

Developer installs: Windows PowerShell:

git clone https://github.com/unslothai/unsloth.git
cd unsloth
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
.\install.ps1 --local
unsloth studio -p 8888

Then to update :

cd unsloth && git pull
./install.sh --local
unsloth studio -p 8888

Nightly: MacOS, Linux, WSL:

git clone https://github.com/unslothai/unsloth
cd unsloth
git checkout nightly
./install.sh --local
unsloth studio -p 8888

Then to launch every time:

unsloth studio -p 8888

Nightly: Windows:

Run in Windows Powershell:

git clone https://github.com/unslothai/unsloth.git
cd unsloth
git checkout nightly
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
.\install.ps1 --local
unsloth studio -p 8888

Then to launch every time:

unsloth studio -p 8888

Advanced launch options

Installer options can be passed as environment variables. On macOS, Linux and WSL place the variable after the pipe so the shell passes it to sh; on Windows set it with $env: before piping to iex.

Skip PyTorch (GGUF-only mode):

curl -fsSL https://unsloth.ai/install.sh | UNSLOTH_NO_TORCH=1 sh
$env:UNSLOTH_NO_TORCH=1; irm https://unsloth.ai/install.ps1 | iex

Pin the Python version:

curl -fsSL https://unsloth.ai/install.sh | UNSLOTH_PYTHON=3.12 sh
$env:UNSLOTH_PYTHON='3.12'; irm https://unsloth.ai/install.ps1 | iex

Install to a custom location with UNSLOTH_STUDIO_HOME:

curl -fsSL https://unsloth.ai/install.sh | UNSLOTH_STUDIO_HOME=/abs/path sh
$env:UNSLOTH_STUDIO_HOME='C:\path'; irm https://unsloth.ai/install.ps1 | iex

Cap Studio's native CPU thread pools on high-core hosts: UNSLOTH_CPU_THREADS=8 unsloth studio -p 8888.

Uninstall

The recommended way to fully remove Unsloth Studio is the matching uninstall script for your OS. It stops any running servers, removes the install dir, the launcher data dir, the desktop shortcut, and any platform-specific entries (macOS .app bundle + Launch Services on Mac; Start Menu, HKCU\Software\Unsloth registry key and user PATH entries on Windows):

  • MacOS, WSL, Linux: curl -fsSL https://raw.githubusercontent.com/unslothai/unsloth/main/scripts/uninstall.sh | sh
  • Windows (PowerShell): irm https://raw.githubusercontent.com/unslothai/unsloth/main/scripts/uninstall.ps1 | iex

If you only want to drop the install dir and keep the launcher/shortcut for a later reinstall, you can instead run rm -rf ~/.unsloth/studio (Mac/Linux/WSL) or Remove-Item -Recurse -Force "$HOME\.unsloth\studio" (Windows). The model cache at ~/.cache/huggingface is not touched by any of these.

For more info, see our docs.

Deleting model files

You can delete old model files either from the bin icon in model search or by removing the relevant cached model folder from the default Hugging Face cache directory. By default, HF uses:

  • MacOS, Linux, WSL: ~/.cache/huggingface/hub/
  • Windows: %USERPROFILE%\.cache\huggingface\hub\
