Merge origin/main into fix/windows-amd-rocm-install

Browse source 
main grew its own Windows AMD ROCm install path while this branch sat open,
and it is a strict superset of what this branch built. main routes Windows
AMD torch through the per-arch pip indexes at repo.amd.com/rocm/whl/<family>/
(install.ps1 $archFamilyMap, setup.ps1 $ROCmIndexUrl, install_python_stack.py
_windows_rocm_index_url), which serve cp310 through cp313 win_amd64 wheels up
to torch 2.11.0+rocm7.13.0 and resolve the ROCm runtime (rocm, rocm-sdk-core,
rocm-sdk-libraries-<gfx>) from the same index.

This branch's route pinned torch 2.9.x from repo.radeon.com/rocm/windows/,
cp312 only, and hand-installed four SDK artefacts because
rocm-sdk-libraries-custom is absent from PyPI. Against main that is a
regression on three counts: it locks AMD hosts to Python 3.12, it installs
exactly the torch <2.11 wheels main blocks on gfx115x/gfx120x for the
torch._C._grouped_mm null-pointer bug (TheRock #5284, #3284), and it skips
bitsandbytes on Windows, which main now installs via
_install_bnb_windows_rocm(). So every conflicting hunk in install.ps1,
studio/setup.ps1 and studio/install_python_stack.py resolves to main.

One hunk from this branch is not superseded and is kept: the Windows
nvidia-smi.exe fallback paths in _has_usable_nvidia_gpu(). main only probes
PATH there, while install.ps1 and setup.ps1 both probe
%ProgramFiles%\NVIDIA Corporation\NVSMI and %SystemRoot%\System32 as well.
That gap matters on an AMD iGPU plus NVIDIA dGPU laptop whose PATH misses
nvidia-smi: the host reads as NVIDIA-free and gets routed to the ROCm wheels.
Grafted onto main's function, below its CUDA_VISIBLE_DEVICES guard.

# Prompt-cache (KV-cache prefix reuse) detection, two strategies in one helper:
#
# mode=api A 2-turn /v1/chat/completions probe. Turn 2 prepends turn 1 +
# its reply, so the shared prefix must be served from llama.cpp's
# KV cache. Asserts usage.prompt_tokens_details.cached_tokens > 0
# on turn 2. This is the OpenAI-dialect server cache sanity.
# WHY this works on chat completions: the chat path forwards
# llama-server's real cached_tokens through
# studio/backend/routes/inference.py:482-489 (_prompt_tokens_details)
# into prompt_tokens_details (inference.py:519).
#
# mode=log Read the llama-server log and decide HIT vs MISS from the
# prompt-reprocessing trace. WHY the log (not the API field):
# the Anthropic /v1/messages path builds AnthropicUsage(
# input_tokens=..., output_tokens=...) at inference.py:8787-8790
# / :8829-8832 and NEVER sets cache_read_input_tokens, which
# therefore stays at its model default of 0
# (studio/backend/models/inference.py:1655). So an Anthropic-path
# client (Claude Code, OpenClaw is openai-completions but Claude
# Code is the canonical Anthropic agent) can get a real KV-cache
# hit that the API usage field reports as 0. The only ground
# truth for the Anthropic path is the llama-server log.
#
# Log location (verified): studio/backend/core/inference/llama_cpp.py:4363-4365
# _swa_cache_path().parent/"logs"/"llama-server"/llama-<ts>[label]-port-<P>[-try<N>].log
# _swa_cache_path() => $UNSLOTH_STUDIO_HOME|$STUDIO_HOME or ~/.unsloth/studio
# (llama_cpp.py:337-340). So default: ~/.unsloth/studio/logs/llama-server/.
#
# <P> is the INTERNAL llama-server port (self._find_free_port(),
# llama_cpp.py:3489 / :4641) -- a RANDOM port, NOT the Unsloth port. So we must
# NOT filter the log glob by STUDIO_PORT (the brief's `port-<STUDIO_PORT>`
# glob would never match). We pick the newest llama-*.log instead.
#
# Usage:
# assert-prompt-cache.sh api BASE_URL API_KEY
# assert-prompt-cache.sh log EXPECT # EXPECT = HIT | MISS
# # reads MARKER_BEFORE/MARKER_AFTER

# Download a single file from a Hugging Face repo with a stall-retry
# watchdog. Used by the Unsloth CI workflows so a hung hf-xet transfer
# kills + retries instead of silently consuming the job's timeout.
#
# Usage: hf-download-with-retry.sh REPO FILE LOCAL_DIR
#
# Why this exists
# ---------------
# huggingface_hub 1.15+ deprecated `hf_transfer` and routes every
# transfer through the `hf-xet` binary package. In CI we observed
# `hf download` on a 3 GB GGUF (gemma-4-E2B-it-UD-Q4_K_XL) progress
# to ~46% via Xet, then go completely silent for the remainder of
# the 30-min job timeout -- no progress bytes, no error, no exit.
# A sibling 940 MB mmproj on the same step downloaded in ~21s
# moments earlier, so the hang is per-file inside hf-xet rather
# than a network outage. The Xet env-vars below put hf-xet into
# its highest-throughput mode and force a 500 s client-read
# timeout; the watchdog loop ensures a stall does not eat the
# whole job: if the hf process has not exited after STALL_S
# seconds (default 180 = 3 min), we SIGTERM, then SIGKILL, then
# start a fresh attempt. Retries are unbounded -- the enclosing
# GitHub Actions job's `timeout-minutes` is the real bound.
#
# See https://huggingface.co/docs/huggingface_hub/package_reference/environment_variables
# for the HF_XET_* documentation, and npm/cli#7308's pattern (silent
# CI hang with no error) for prior art on this class of failure.

# Boot `unsloth run --disable-tools` in the background, wait for it to be
# healthy, parse the minted API key from the banner, and resolve the
# /v1/models id. Exports everything downstream steps need into $GITHUB_ENV
# (or prints it when run outside Actions). Factored out of the workflow so

#
# Why a helper and not inline YAML
# --------------------------------
# * Every `unsloth run` invocation here is the *Unsloth server* under test.
# A failure to come up healthy is class (a) "server/API regression" and
# must be reported with a distinct `::error::` BEFORE any agent runs.
# * The banner is the documented contract a human copies from. We parse the
# exact `API Key:` line printed by unsloth_cli/commands/studio.py
# (` API Key: <key>` non-silent, `API Key: <key>` silent) so a
# silent change to that line is also caught.
# * `unsloth run` re-execs into the studio venv ($STUDIO_HOME/unsloth_studio),
# so in CI after `install.sh --local` it runs the PR's repo code.
#
# Outputs written to $GITHUB_ENV (and echoed):
# UNSLOTH_API_KEY the sk-unsloth-* key minted on the banner

# finds THIS server, not the hardcoded :8888)

# Whole-repo, multi-language source-lint gate. Runs on every PR
# (no path filter) because each step is sub-second to a few seconds
# and together they catch a class of breakage the focused build
# workflows would miss:
#
# - Python syntax + ruff + leftover debugger calls (across 350+
# committed .py files, not just studio/backend).
# - Shell `bash -n` parse for every committed *.sh.
# - `yaml.safe_load` and `json.loads` round-trip for every
# committed YAML / JSON config.
#
# TypeScript and Rust are NOT duplicated here on purpose:
# - Unsloth Frontend CI runs `npm run typecheck` (= `tsc --noEmit`)
# and `npm run build` (vite/swc) on every studio/frontend/**
# change, which is a full TS AST + type check.
# - Unsloth Tauri CI runs `tauri build --debug --no-bundle` on
# every studio/src-tauri/** or studio/frontend/** change, which
# compiles the Rust crate (= cargo check + cargo build).
# Each is a stricter check than a parse-only step would be, so a
# fast-fail duplicate here would only burn cache; the dedicated
# workflows already block merges on Rust / TS regressions.

# against two bugs ruff and pyflakes both miss:
# 1. dangling alias -- `from a import b as _b` hoisted to
# `from a import b` but a leftover `_b` reference now
# resolves to nothing (or to some other module-level `_b`).
# 2. rename clash -- `_b -> b` silently re-points at a
# different object already named `b` in that scope.
# This step runs the tool's 8 negative-control cases so a
# regression in the verifier itself fails before we trust it on
# a diff. Hermetic, stdlib-only, sub-second. Hard gate.

# Runs the verifier in compare mode on every in-place-modified

# (this diff), resolves every name load, and fails on a BLOCKER
# (dangling alias / rename clash / re-pointed import). INFO
# findings (a helper relocated to another file) do not fail.
#
# --diff-filter=M (in-place edits only) is deliberate: that is
# exactly where a hoist refactor lives, and it skips brand-new
# files whose re-export imports would otherwise look "unused".
#
# Diff against the true merge-base, not the base tip. A two-dot
# diff against the tip re-lints every file the base branch
# changed after the PR branched, comparing newer base code
# (BEFORE) against the PR's older snapshot (AFTER) - a
# time-reversed comparison that flags the base branch's own
# refactors as blockers on PRs that never touched those files.
# The compare API returns the merge-base without needing local
# history, and fetching that single commit by SHA keeps the
# shallow (fetch-depth: 1) clone.

# Local Agent Guides CI
# =====================
# Detects when our local-agent setup recipes drift out of sync with
# `unsloth run`. Boots a real `unsloth run --disable-tools` server and
# drives the coding agents end to end through the *exact* recipes defined
# in unsloth_cli/commands/start.py (the in-repo source of truth -- there
# is no docs/ tree). Wherever start.py has a recipe we drive the agent
# via `unsloth start <agent> --no-launch` and execute what it prints, so
# the test self-updates against start.py and catches silent recipe drift.
#
# Source-of-truth files this workflow guards:
# unsloth_cli/commands/start.py the `unsloth start <agent>` recipes
# unsloth_cli/commands/studio.py the `unsloth run` banner (API Key line)
#
# Failure taxonomy (each surfaced with a distinct ::error:: + the agent name
# + the start.py location, so a red X is immediately triageable):
# (a) Unsloth server/API regression -- the dialect HTTP preflight fails
# BEFORE the agent runs (or the server never becomes healthy).
# (b) Agent package install failed -- npm/curl install of the CLI failed.
# (c) Guide drift -- preflight passed + install ok, but
# the documented `unsloth start` flow produced no/garbled output.
#
# Agents covered (6): claude, codex, hermes, openclaw, opencode, pi.
# - All six have a `unsloth start <agent>` recipe, so each cell obtains its
# env + command from `unsloth start <agent> --no-launch` and runs THAT
# (self-updating: a recipe change is exercised automatically).

# Fast, focused supply-chain audit of every checked-in lockfile.
#
# Runs scripts/lockfile_supply_chain_audit.py on PRs that touch any
# npm or cargo lockfile, on push to main, and on a daily schedule so
# newly-published IOCs surface even when no PR opens.
#
# Default behavior is "advisory": only public indicator-of-compromise
# strings, known-malicious pinned versions, and structurally broken
# lockfiles fail the build. Structural anomalies (missing integrity,
# non-default registry, etc.) are emitted as GitHub Actions warnings
# but do not block merges. This deliberately keeps the noise floor
# low while still failing the moment a checked-in lockfile starts
# pointing at known-bad bytes.
#
# This workflow is intentionally separate from security-audit.yml:
# - security-audit.yml is the umbrella job (pip-audit + npm audit +
# cargo audit + OSV + Semgrep + secret scanning + SBOM + ...);
# it takes ~25 minutes and runs only when dep manifests change.
# - lockfile-audit.yml is a ~30 second pure-Python parse + grep on
# the lockfiles themselves; it runs on every PR that even nudges
# a lockfile so reviewers always see the audit result inline.

# Focused PR gate for the MLX dispatch surface, running on a real
# Apple Silicon runner.
#
# Runner: macos-14 (M1, 3 vCPU / 7 GB / Apple Silicon standard runner
# -- FREE for public repositories per the GitHub Actions billing
# reference; larger variants like macos-14-large/-xlarge are paid so
# we deliberately avoid those).
#
# Why a single Mac job (no Linux+spoof leg): the dispatch tests are
# 100% spoofed monkeypatches and run identically on any host, so the
# Linux leg was duplicating the matrix tests already covered on Mac
# while missing everything Apple-specific. The Mac job runs the SAME
# spoofed matrix PLUS three things only a real Apple Silicon host
# can prove:
#
# 1. unsloth._IS_MLX flips True on Darwin+arm64 with mlx genuinely
# installed (no spoof).
# 2. Every PR-A MLX-only unsloth_zoo module (mlx_loader, mlx_trainer,
# mlx_compile, mlx_utils, mlx_cce, gated_delta_vjp) imports
# against the real `mlx` + `mlx-lm` + `mlx-vlm` PyPI wheels --
# each does `import mlx.core as mx` at module top level, so this
# catches a future change that breaks the real wheels without
# needing a Mac developer in the loop.
# 3. The hardware-dispatch spoofs do not collide with the real
# environment (the test fixture installs a MetaPathFinder that
# blocks `import mlx.core` for "no-mlx" profiles, faithfully
# simulating a Mac without mlx even when mlx IS installed).
# 4. End-to-end MLX training + inference smoke test:
# run_real_mlx_smoke.py trains unsloth/gemma-3-270m-it for 7
# deterministic LoRA steps on a single repeated text row, then
# verifies the trained model can complete the prompt and that
# losses + grad norms are finite and well-behaved. This is the
# only place in CI that exercises a real MLX backward pass +
# optimizer step + inference call.
#
# Three dispatch test files documented in tests/studio/README.md:
# - test_hardware_dispatch_matrix.py parametrized 7-profile matrix
# + 2 dispatch-priority canaries
# - test_is_mlx_dispatch_gate.py AST + runtime guard on
# unsloth._IS_MLX
# - test_mlx_training_worker_behaviors.py AST contract checks on
# studio/backend/core/training/worker.py
#
# Surfaces a single PR check ("MLX CI on Mac M1 / dispatch").
#
# Security audit footprint: every package this workflow installs is
# already covered by .github/workflows/security-audit.yml -- the deps
# come from studio/backend/requirements/studio.txt and unsloth-zoo's
# pyproject (resolved transitively). The git+ install of unsloth-zoo
# is intentionally skipped by the audit (pip-audit cannot resolve a
# git URL through PyPI metadata; the audit comment in security-audit.yml
# documents this). No new package is introduced solely by MLX CI.

# 1. studio/backend/requirements/studio.txt brings structlog,
# fastapi, etc. The hardware probe imports structlog at
# module top level.
# 2. Same pytest / numpy / httpx stack the rest of the repo CI
# uses.
# 3. torch is explicitly installed: unsloth-zoo's pyproject
# deliberately excludes torch on darwin+arm64 (mlx replaces
# it for runtime use), but the dispatch tests spoof
# torch.cuda / torch.xpu / torch.backends.mps via monkeypatch
# and so the test process needs torch importable. We pull
# from the PyTorch CPU index so Apple Silicon gets the
# explicit cpu+MPS arm64 wheel rather than something the
# default PyPI resolver might pick up. The CPU index hosts
# macosx_*_arm64 wheels alongside the Linux x86_64 ones.
# 4. unsloth-zoo from git main (NOT PyPI), WITH deps. PR-A's
# MLX support landed after the most recent unsloth-zoo PyPI
# release; the wheel still raises NotImplementedError on
# Apple Silicon when device_type.get_device_type() runs
# unguarded. Unsloth's own install.sh overlays unsloth-zoo
# from git main for the same reason. Pulling deps lets pip
# resolve the platform-conditional MLX-only wheels (mlx,
# mlx-lm, mlx-vlm gated on darwin+arm64 in unsloth-zoo's
# pyproject) AND the shared deps (datasets, transformers,
# sentencepiece, ...) that unsloth's MLX branch loads via
# dataprep/raw_text.py.
# 5. unsloth -e . --no-deps so the editable install does not
# fight the unsloth-zoo dep set.
#
# All explicit pip installs are version-pinned to a single
# released version (the latest as of 2026-05-07 within each
# project's existing constraint range). bump alongside the rest
# of the security audit when a new release lands.

# headless Linux runner. Boots Unsloth with the smallest GGUF
# (gemma-3-270m-it UD-Q4_K_XL, ~254 MiB), drives the actual frontend
# bundle, and asserts the full bootstrap-password / change-password /
# send-message / persist-on-reload journey works end to end.
#
# This is the only workflow that catches regressions in the wiring
# between the React frontend and the FastAPI backend, e.g. assistant-ui
# version drift, /api/auth response shape changes, runtime-provider
# regressions, or chat-history persistence breaking. Backend-only and
# frontend-only CI happily pass while the actual user-visible UI is
# broken (cf. the 2026.5.1 chat-history release).

# Two surgical fixes against measured Windows-only install
# waste (vs Mac/Linux on the same SHA):
#
# (1) npm. setup.ps1's Get-NodeDecision requires Node 22.12+
# (or 20.19+ / 23+) AND npm >=11 because Vite 8 needs both.
# actions/setup-node@v4 with `node-version: '22'` lands
# Node 22.22.2 + the npm 10.9.7 it bundles, so the decision
# is "bundled" and setup.ps1 downloads an isolated Node (~30
# MB) we don't need on a runner that already has a fine Node.
# `npm install -g npm@^11` updates the runner's npm in-place
# in ~5 s, flipping the decision to "system" so setup.ps1
# reuses the existing Node with no download.
#
# (2) Defender. windows-latest's real-time scan opens / hashes
# every file Unsloth writes during install (Vite output =
# thousands of small chunks, uv pip = wheel-extraction =
# thousands of small files). The latency dominates the
# 200 s frontend build and the 90 s deps install. Adding
# ExclusionPath entries for the directories the install
# writes to drops per-file open latency from ~ms to ~us.
# Add-MpPreference needs admin; the runneradmin user has
# it, but wrap in try/catch so a permission flake leaves
# the install otherwise unaffected.

Unsloth Studio (Beta) lets you run and train text, [audio](https://unsloth.ai/docs/basics/text-to-speech-tts-fine-tuning), [embedding](https://unsloth.ai/docs/new/embedding-finetuning), [vision](https://unsloth.ai/docs/basics/vision-fine-tuning) models on Windows, Linux and macOS.
## ⭐ Features
Unsloth provides several key features for both inference and training:
### Inference
* **Search + download + run models** including GGUF, LoRA adapters, safetensors
* **Export models**: [Save or export](https://unsloth.ai/docs/new/studio/export) models to GGUF, 16-bit safetensors and other formats.
* **Tool calling**: Support for [self-healing tool calling](https://unsloth.ai/docs/new/studio/chat#auto-healing-tool-calling) and web search

## 🚀 Unsloth Start
[Unsloth Start](https://unsloth.ai/docs/integrations/unsloth-start) connects [Claude Code](https://unsloth.ai/docs/basics/claude-code), [Codex](https://unsloth.ai/docs/basics/codex) and other agents to local models with one command.
Start Unsloth, load a model, open your project folder, then run:
```bash
unsloth start claude
```
Replace `claude` with any supported agent:
| Agent | Command |
| --- | --- |
| Claude Code | `unsloth start claude` |
| OpenAI Codex | `unsloth start codex` |
| Hermes Agent | `unsloth start hermes` |
| OpenClaw | `unsloth start openclaw` |
| OpenCode | `unsloth start opencode` |
| Pi Coding Agent | `unsloth start pi` |
Claude Code, Codex, OpenCode and Pi can keep their current model and use Unsloth as a local
subagent:
```bash
unsloth start claude --as-subagent --model unsloth/model-GGUF:quant
```
## 📥 Install
Unsloth can be used in two ways: through **[Unsloth Studio](https://unsloth.ai/docs/new/studio/)**, the web UI, or through **Unsloth Core**, the code-based version. Each has different requirements.
### Unsloth Studio (web UI)
Unsloth Studio (Beta) works on **Windows, Linux, WSL** and **macOS**.
* **CPU:** Supported for Chat and Data Recipes currently
* **NVIDIA:** Training works on RTX 30/40/50, Blackwell, DGX Spark, Station and more
* **macOS:** Training, MLX and GGUF inference are ALL supported.
* **AMD:** Training, RL, chat and deployment work on Windows, WSL and Linux. [Read the AMD guide](https://unsloth.ai/docs/basics/amd).
* **Vulkan:** GGUF inference is supported on [compatible GPUs, including Intel GPUs](https://github.com/unslothai/unsloth/pull/5819). Vulkan accelerates GGUF inference only; training still requires a supported PyTorch or MLX backend.
* **Multi-GPU:** Available now, with a major upgrade on the way
#### macOS, Linux, WSL:
```bash
curl -fsSL https://unsloth.ai/install.sh | sh
```
Use the same command to update.
To force the Vulkan llama.cpp backend, set `UNSLOTH_FORCE_VULKAN=1` **before installing or updating**. The setting selects the llama.cpp binary bundle, so setting it only when launching Studio cannot replace an existing CPU bundle:
```bash
export UNSLOTH_FORCE_VULKAN=1
curl -fsSL https://unsloth.ai/install.sh | sh
```
#### Windows:
```powershell
irm https://unsloth.ai/install.ps1 | iex
```
Use the same command to update.
To force the Vulkan llama.cpp backend, set the environment variable before running the installer or updater:
```powershell
$env:UNSLOTH_FORCE_VULKAN=1
irm https://unsloth.ai/install.ps1 | iex
```
Re-running the current installer replaces a previously selected CPU bundle when the backend differs. A separate Vulkan SDK is not required; the GPU driver must provide a working Vulkan runtime.
#### Launch
```bash
unsloth studio -H 0.0.0.0 -p 8888
unsloth studio -p 8888
```
For LAN or cloud access, add `-H 0.0.0.0` (raw port only; add `--cloudflare` for a public URL). By default, Unsloth is accessible only locally.
#### Update
To update, use the same install commands as above. Or run (does not work on Windows):
```bash
unsloth studio update
```
To reach Unsloth over HTTPS, use `unsloth studio --secure`. Unsloth stays bound to localhost and is reached only through a free Cloudflare tunnel, which publishes it at a public `https://*.trycloudflare.com` URL (it fails closed if the tunnel can't start, so the raw port is never exposed). This makes Unsloth reachable from the internet, so anyone with the link and API key can use it and run code: keep your API key private (see Remote access below).

```powershell
cd unsloth; git pull
.\install.ps1 --local
unsloth studio -H 0.0.0.0 -p 8888
unsloth studio -p 8888
```
Then to launch every time:
#### Remote access: `--secure` (HTTPS tunnel) vs raw port
By default `unsloth studio` binds to `127.0.0.1` (this machine only). To reach it from another device, pick one of:
- `--secure` (recommended): serve **only** through a free Cloudflare HTTPS link. Unsloth stays bound to localhost and the tunnel provides the public URL; it fails closed (does not start) if the tunnel can't come up, so the raw port is never exposed.
```bash
unsloth studio --secure -p 8888
```
- `-H 0.0.0.0`: bind the raw port on all network interfaces, reachable from anywhere on the network (subject to your firewall). It does not create a public internet URL; add `--cloudflare` to also publish an internet-reachable `https://*.trycloudflare.com` link even behind a firewall. Only use this on a network you trust.
```bash
unsloth studio -H 0.0.0.0 -p 8888
```
The Cloudflare tunnel is **off by default**: `-H 0.0.0.0` exposes the raw port only, not a public internet URL. Pair the wildcard bind with `--cloudflare` (`unsloth studio -H 0.0.0.0 --cloudflare`) to also publish a public `https://*.trycloudflare.com` link, or prefer `--secure` (above), which keeps the raw port private. `--cloudflare` has no effect on a loopback bind.
On a wildcard bind Unsloth works out the address to share by asking `ifconfig.me` for the public IP, then asks `check-host.net` whether that port is reachable so it can tell you if a firewall is in the way. Both contact a third party. Set `UNSLOTH_STUDIO_DISABLE_PUBLIC_CHECK=1` to skip them; the banner then shows the LAN address and no reachability line.
The first time Unsloth is published on a public URL (`--secure` or `--cloudflare`) with the auto-generated admin password still in place, it asks for a new admin password in the terminal (masked input with confirmation) before the public link goes up. Without an attached terminal it warns instead and keeps the bootstrap deadline: Unsloth shuts down after `UNSLOTH_STUDIO_BOOTSTRAP_TIMEOUT` (default 1 hour) unless the password is changed in the web UI.
For headless setups that cannot answer that prompt, set the initial admin password non-interactively with `--password` (only takes effect when no password is set yet; if one already exists it is a hard error, so rotate later with `unsloth studio reset-password`):
```bash
unsloth studio --secure --password 'your-strong-password' # visible in `ps`/history
UNSLOTH_STUDIO_PASSWORD='your-strong-password' unsloth studio --secure # via env var
printf '%s\n' 'your-strong-password' | unsloth studio --secure --password - # via stdin
```
A literal `--password VALUE` is visible in the process list and shell history, so prefer the `UNSLOTH_STUDIO_PASSWORD` env var or `--password -` (stdin) for automation. This applies to any launch (public or a headless `-H 0.0.0.0` bind), and the password is set in the parent before the server binds, so it never reaches a re-executed child process.
Server-side tools (web search, Python and terminal code execution) run as your user and are on by default. Anyone who can reach the server with the API key can run code on this machine, so keep your API key private and pass `--disable-tools` when exposing Unsloth.
#### 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):
```bash
curl -fsSL https://unsloth.ai/install.sh | UNSLOTH_NO_TORCH=1 sh
```
```powershell
$env:UNSLOTH_NO_TORCH=1; irm https://unsloth.ai/install.ps1 | iex
```
Skip the post-install prompt that starts Unsloth (useful for automated installs):
```bash
curl -fsSL https://unsloth.ai/install.sh | UNSLOTH_SKIP_AUTOSTART=1 sh
```
```powershell
$env:UNSLOTH_SKIP_AUTOSTART=1; irm https://unsloth.ai/install.ps1 | iex
```
Pin the Python version:
```bash
curl -fsSL https://unsloth.ai/install.sh | UNSLOTH_PYTHON=3.12 sh
```
```powershell
$env:UNSLOTH_PYTHON='3.12'; irm https://unsloth.ai/install.ps1 | iex
```
Install to a custom location with `UNSLOTH_STUDIO_HOME`:
```bash
curl -fsSL https://unsloth.ai/install.sh | UNSLOTH_STUDIO_HOME=/abs/path sh
```
```powershell
$env:UNSLOTH_STUDIO_HOME='C:\path'; irm https://unsloth.ai/install.ps1 | iex
```
On macOS, the installer defaults to the system certificate store (`UV_SYSTEM_CERTS=1`) so uv trusts the CAs in your Keychain, needed behind TLS-inspecting proxies (Cisco Umbrella, Zscaler, etc.). Opt out with:
```bash
curl -fsSL https://unsloth.ai/install.sh | UV_SYSTEM_CERTS=0 sh
```
Point the frontend build at a corporate npm mirror/proxy with `UNSLOTH_NPM_REGISTRY` (for the developer install behind a firewall that blocks `registry.npmjs.org`):
```bash
UNSLOTH_NPM_REGISTRY=https://artifactory.example.com/api/npm/npm/ ./install.sh --local
```
```powershell
$env:UNSLOTH_NPM_REGISTRY='https://artifactory.example.com/api/npm/npm/'; .\install.ps1 --local
```
It is threaded as `--registry` into the Unsloth frontend `npm`/`bun` installs; the supply-chain locks (7-day `min-release-age`, exact version pins) stay in force.
Cap Unsloth's native CPU thread pools on high-core hosts: `UNSLOTH_CPU_THREADS=8 unsloth studio -p 8888`.
#### Uninstall
You can uninstall Unsloth Studio by deleting its install folder usually located under `$HOME/.unsloth/studio` on Mac/Linux/WSL and `%USERPROFILE%\.unsloth\studio` on Windows. Using the `rm -rf` commands will **delete everything**, including your history, cache:
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:** `rm -rf ~/.unsloth/studio`
* ​ **Windows (PowerShell):** `Remove-Item -Recurse -Force "$HOME\.unsloth\studio"`
* ​ **MacOS, WSL, Linux:** `curl -fsSL https://raw.githubusercontent.com/unslothai/unsloth/main/scripts/uninstall.sh | sh`
* ​ **Windows (PowerShell):** `irm https://raw.githubusercontent.com/unslothai/unsloth/main/scripts/uninstall.ps1 | iex`
If you only want to drop the install dir and keep the launcher/shortcut for a later reinstall, you can instead run `rm -rf ~/.unsloth/studio` (Mac/Linux/WSL) or `Remove-Item -Recurse -Force "$HOME\.unsloth\studio"` (Windows). The model cache at `~/.cache/huggingface` is not touched by any of these.

"""Diff two `package-lock.json` files and flag NEW install-script deps.
A `"hasInstallScript": true` package runs preinstall/install/postinstall

compromises (attacker publishes a malicious version of a trusted dep).
This refuses to land a newly-introduced install-script dep without a
maintainer eyeball; pre-existing ones are not re-flagged.
Supports lockfileVersion 1 (recursive `dependencies`) and 2/3 (flat
`packages` with `node_modules/.../node_modules/...` nesting). For each
new entry we best-effort fetch the registry metadata to recover the
postinstall command body; the finding is still emitted if unreachable.

# Enable ROCm-on-WSL for AMD GPUs (Strix Halo/Point APUs AND discrete Radeon RX

# ──────────────────────────────────────────────────────────────────────────────
# install.sh routes the detected arch to the right ROCm wheels once a runtime exists;
# what it does NOT do is install AMD's ROCm userspace + the WSL DXG bridge (librocdxg).
# This helper does that Linux-side prerequisite on Ubuntu 24.04 WSL2, invoked by
# install.sh when it sees an AMD GPU via /dev/dxg but no ROCm yet. Arch-agnostic: the
# arch is auto-detected from rocminfo (override UNSLOTH_WSL_GFX=gfx1200). Idempotent.
#
# Manual, admin-gated Windows prerequisite: an AMD Adrenalin driver with
# production ROCDXG/WSL support (26.2.2+). install.ps1 offers to update it. Once
# installed + rebooted, /dev/dxg is exposed to WSL and this script builds the rest.
#
# HOW ROCDXG WORKS (and why older /usr/lib/wsl/lib notes are wrong): librocdxg.so
# is AMD's user-mode bridge between the Linux HSA runtime and the Windows driver
# over /dev/dxg. The STANDARD hsa-rocr runtime (NOT the gone "roc4wsl" package)
# loads it when HSA_ENABLE_DXG_DETECTION=1. No hsa/rocm libs need injecting into
# /usr/lib/wsl/lib (it holds only d3d12/dxcore), yet rocminfo enumerates gfx1151
# fine -- so we gate on /dev/dxg, not on WSL lib injection.
#
# KNOWN CAVEAT (ROCm/ROCm#6022): librocdxg can cap usable ROCm VRAM at the WSL
# VM's RAM (.wslconfig [wsl2] memory=) on some BIOS UMA layouts, and amd-smi
# doesn't work in WSL. On OOM below capacity, raise memory= (then wsl --shutdown)
# and watch GPU use from Windows. Large-UMA BIOS exposes the full pool regardless.

"""Keep `allowScripts` pins in studio/frontend/package.json in sync with
package-lock.json.
`npm approve-scripts` writes version-pinned entries ("pkg@1.2.3": true).
A dependency bump strands the pin, so the approval (or denial) silently
stops matching and the package's install scripts fall back to
"unreviewed". This tool re-pins existing entries to the versions the
lockfile actually resolves; it never adds or removes entries, so
approving a brand-new script-bearing package stays a human decision.
Usage:
python scripts/sync_allow_scripts_pins.py --check # CI: exit 1 on drift
python scripts/sync_allow_scripts_pins.py --fix # rewrite package.json
Pinned keys follow npm's allowScripts grammar: "name@1.2.3" or
"name@1.2.3 || 1.2.4". Bare names (no version) match every version and
are left alone. Entries whose range is not an exact-version disjunction
(wildcards, tags) are left alone too.

"""Deterministic comment / docstring-only verifier.
Compares a list of changed files between two git refs and reports whether
each diff is strictly comments / docstrings (Python) or comments
(YAML / GitHub Actions). Useful for gating a "comment trim" /
"docstring refactor" PR against accidental code drift.
Per .py file: parse both revs into AST, strip module / class / function
docstrings, then compare ast.unparse output. Pure Python comments are
discarded by the parser by construction, so any post-strip diff is real
code. Per .yml file: yaml.safe_load both sides and compare the parsed
Python object; if scalar values differ, also strip shell comments inside
``run: |`` block bodies before comparing. Exit code 0 = all OK, 1 = at
least one file has a real (non-comment) diff or an error.

"""Deterministic, scope-aware verifier for import-hoisting / alias-rename refactors.
The risk when moving `from a import b as _b` (or `import b as _b`) to module top
and normalizing `_b` -> `b` is twofold:
1. DANGLING ALIAS - a `_b` reference is left un-normalized; it now resolves to
nothing (NameError) or, worse, to some *other* module-level `_b`.
2. RENAME CLASH - `_b` was an alias on purpose because `b` already meant
something else in that scope; normalizing `_b` -> `b` silently re-points the
reference at the wrong object (no NameError, no pyflakes warning).
This tool parses BEFORE (a git ref, default origin/main) and AFTER (default HEAD)
for each file, builds a real LEGB scope model (functions, classes, lambdas,
comprehensions, global/nonlocal, args, walrus, star-imports), and resolves every
Name load to its binding. It then compares, PER SCOPE:
* UNRESOLVED-NEW : loads that resolve to nothing in AFTER but did in BEFORE
(or are newly present) -> catches dangling aliases.
* TARGET-MISSING : an import *target* (e.g. module `glob`, or
`importlib.metadata.version`) that a function resolved to
in BEFORE but no longer resolves to in AFTER -> catches a
function that lost access to a module it still uses.
Robust to alias renames because it compares the *target*,
not the local name.
* TARGET-CHANGED : a load whose resolved import target differs BEFORE vs
AFTER -> catches a rename that re-points to a different
module (the clash case).
* AMBIGUOUS-BIND : a name bound by BOTH an import and a non-import in the same
scope in AFTER (and not in BEFORE) -> the "alias was on
purpose / now collides" smell.
* MODULE-DUP-IMPORT: a module-level name imported and also defined/assigned at
module level (introduced by the change).
* NEW-UNUSED-IMPORT: a module-level import added in AFTER that nothing resolves
to (informational; re-exports are a known false positive).
Usage:
verify_import_hoist.py [--before REF] [--after REF] <file>... # compare
verify_import_hoist.py --self-test # prove it catches bugs
Exit code 1 if any non-informational finding.

# keeps its spelling but its import source is moved A -> B in THIS diff (the
# old `from A import x` is removed at module level and a new `from B import x`
# is added), the swap is intentional, not a silent re-point to a pre-existing

# Unsloth Studio MCP server
Unsloth can expose a local MCP server so an MCP client can inspect models and
GPU state, validate recipes, start or stop training, inspect recipe output, and
export a loaded model.
The server is disabled by default. Enable it for a local Unsloth process with:
```bash
UNSLOTH_STUDIO_ENABLE_MCP=1 \
UNSLOTH_STUDIO_MCP_TOKEN='use-a-local-secret' \
unsloth studio
```
The endpoint is `http://127.0.0.1:8888/mcp/` when Unsloth uses its default port
(a request to `/mcp` redirects to the canonical `/mcp/`). Use the actual Unsloth
port when it is configured differently.
The high-impact tools are:
- `studio_status` and `list_local_models` for discovery
- `get_training_status`, `start_training`, `stop_training`, and `list_training_runs`
- `validate_recipe`, `get_recipe_job_status`, and `get_recipe_job_dataset`
- `load_checkpoint` and `export_gguf`
`start_training` accepts the same fields as the Unsloth `TrainingStartRequest`.
The request is validated by the existing Pydantic model before a subprocess is
started. Export paths use the existing Unsloth validation as well.
The endpoint always requires `UNSLOTH_STUDIO_MCP_TOKEN` and checks an exact
Bearer token for both HTTP and WebSocket connections. Keep it on localhost
unless the deployment has an authenticated reverse proxy. The MCP endpoint is
intentionally opt-in because tools can consume GPU memory, write model
artifacts, and stop active work.

Compatibility shim for Anaconda/conda-forge Python builds.
Anaconda modifies sys.version to include distributor metadata between pipe

raising ValueError. CPython closed this as "not planned" (cpython#102396).

{#-
Gemma 4 chat template (E2B / E4B edge variant), vendored for Unsloth Studio.
Source: google/gemma-4-31B-it HF discussion/PR #118 (adds the preserve_thinking
flag plus null-rendering, string-arguments validation, balanced turn tags, empty
messages handling, and OpenAI image_url/input_audio aliases).
Unsloth-local changes vs PR #118:
1. preserve_thinking defaults to false (see SETUP block below).
2. The empty "<|channel>thought\n<channel|>" block on enable_thinking=false is
NOT emitted. Google ships a distinct template for E2B/E4B (google/gemma-4-E2B-it,
google/gemma-4-E4B-it) that omits it; only the 12b/26B-A4B/31B family emits it.
This file matches the E2B/E4B behavior; gemma-4.jinja keeps the larger-model one.
Applied to unsloth/gemma-4-E2B-it-GGUF and unsloth/gemma-4-E4B-it-GGUF so the
embedded GGUF template does not need re-downloading.
