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:** Chat + Data works. Train with [Unsloth Core](#unsloth-core-code-based). Studio support is out soon. * **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. #### Windows: ```powershell irm https://unsloth.ai/install.ps1 | iex ``` Use the same command to update. #### Launch ```bash unsloth studio -p 8888 ``` For cloud or global access, add `-H 0.0.0.0`. By default, Unsloth is accessible only locally. To reach Studio over HTTPS, use `unsloth studio --secure`. Studio 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 Studio 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). #### Docker Use our [Docker image](https://hub.docker.com/r/unsloth/unsloth) ```unsloth/unsloth``` container. Run: ```bash docker run -d -e JUPYTER_PASSWORD="mypassword" \ -p 8888:8888 -p 8000:8000 -p 2222:22 \ -v $(pwd)/work:/workspace/work \ --gpus all \ unsloth/unsloth ``` #### Developer, Nightly, Uninstall To see developer, nightly and uninstallation etc. instructions, see [advanced installation](#-advanced-installation). ### Unsloth Core (code-based) #### Linux, WSL: ```bash curl -LsSf https://astral.sh/uv/install.sh | sh uv venv unsloth_env --python 3.13 source unsloth_env/bin/activate uv pip install unsloth --torch-backend=auto ``` #### Windows: ```powershell winget install -e --id Python.Python.3.13 winget install --id=astral-sh.uv -e uv venv unsloth_env --python 3.13 .\unsloth_env\Scripts\activate uv pip install unsloth --torch-backend=auto ``` For Windows, `pip install unsloth` works only if you have PyTorch installed. Read our [Windows Guide](https://unsloth.ai/docs/get-started/install/windows-installation). You can use the same Docker image as Unsloth Studio. #### AMD, Intel: For RTX 50x, B200, 6000 GPUs: `uv pip install unsloth --torch-backend=auto`. Read our guides for: [Blackwell](https://unsloth.ai/docs/blog/fine-tuning-llms-with-blackwell-rtx-50-series-and-unsloth) and [DGX Spark](https://unsloth.ai/docs/blog/fine-tuning-llms-with-nvidia-dgx-spark-and-unsloth).

For Unsloth Core advanced installation, [view our docs](https://unsloth.ai/docs/get-started/install/pip-install#advanced-pip-installation). #### Developer / Nightly / Experimental installs: macOS, Linux, WSL: The developer install builds from the `main` branch, which is the latest (nightly) source. ```bash git clone https://github.com/unslothai/unsloth cd unsloth ./install.sh --local unsloth studio -p 8888 ``` To install into an isolated location (its own virtual env, `auth/`, `studio.db`, cache and llama.cpp build), set `UNSLOTH_STUDIO_HOME` and pass it again at launch: ```bash UNSLOTH_STUDIO_HOME="$PWD/.studio" ./install.sh --local UNSLOTH_STUDIO_HOME="$PWD/.studio" unsloth studio -p 8888 ``` Then to update : ```bash cd unsloth && git pull ./install.sh --local unsloth studio -p 8888 ``` #### Developer / Nightly / Experimental installs: Windows PowerShell: The developer install builds from the `main` branch, which is the latest (nightly) source. ```powershell git clone https://github.com/unslothai/unsloth.git cd unsloth Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass .\install.ps1 --local unsloth studio -p 8888 ``` To install into an isolated location (its own virtual env, `auth/`, `studio.db`, cache and llama.cpp build), set `UNSLOTH_STUDIO_HOME` and pass it again at launch: ```powershell $env:UNSLOTH_STUDIO_HOME="$PWD\.studio"; .\install.ps1 --local $env:UNSLOTH_STUDIO_HOME="$PWD\.studio"; unsloth studio -p 8888 ``` Then to update : ```powershell cd unsloth; git pull .\install.ps1 --local unsloth studio -p 8888 ``` #### 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. Studio 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. This also starts a public Cloudflare quick tunnel by default, which publishes an internet-reachable `https://*.trycloudflare.com` URL even behind a firewall. Both the raw port and the tunnel expose Studio beyond this machine, so only use this on a network you trust; pass `--no-cloudflare` to drop the public link while keeping the network bind. ```bash unsloth studio -H 0.0.0.0 -p 8888 ``` 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 Studio. #### 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 ``` 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 $env:UNSLOTH_NPM_REGISTRY='https://artifactory.example.com/api/npm/npm/'; .\install.ps1 --local ``` It is threaded as `--registry` into the Studio frontend `npm`/`bun` installs; the supply-chain locks (7-day `min-release-age`, exact version pins) stay in force. Cap Studio's native CPU thread pools on high-core hosts: `UNSLOTH_CPU_THREADS=8 unsloth studio -p 8888`. #### Uninstall The recommended way to fully remove Unsloth Studio is the matching uninstall script for your OS. It stops any running servers, removes the install dir, the launcher data dir, the desktop shortcut, and any platform-specific entries (macOS `.app` bundle + Launch Services on Mac; Start Menu, `HKCU\Software\Unsloth` registry key and user `PATH` entries on Windows): * ​ **MacOS, WSL, Linux:** `curl -fsSL https://raw.githubusercontent.com/unslothai/unsloth/main/scripts/uninstall.sh | sh` * ​ **Windows (PowerShell):** `irm https://raw.githubusercontent.com/unslothai/unsloth/main/scripts/uninstall.ps1 | iex` If you only want to drop the install dir and keep the launcher/shortcut for a later reinstall, you can instead run `rm -rf ~/.unsloth/studio` (Mac/Linux/WSL) or `Remove-Item -Recurse -Force "$HOME\.unsloth\studio"` (Windows). The model cache at `~/.cache/huggingface` is not touched by any of these. For more info, [see our docs](https://unsloth.ai/docs/new/studio/install#uninstall). #### 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\` ## 💚 Community and Links | Type | Links | | ----------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------ | |   **Discord** | [Join Discord server](https://discord.com/invite/unsloth) | |   **r/unsloth Reddit** | [Join Reddit community](https://reddit.com/r/unsloth) | | 📚 **Documentation & Wiki** | [Read Our Docs](https://unsloth.ai/docs) | |   **Twitter (aka X)** | [Follow us on X](https://twitter.com/unslothai) | | 🔮 **Our Models** | [Unsloth Catalog](https://unsloth.ai/docs/get-started/unsloth-model-catalog) | | ✍️ **Blog** | [Read our Blogs](https://unsloth.ai/blog) | ### Citation You can cite the Unsloth repo as follows: ```bibtex @software{unsloth, author = {Daniel Han, Michael Han and Unsloth team}, title = {Unsloth}, url = {https://github.com/unslothai/unsloth}, year = {2023} } ``` If you trained a model with 🦥Unsloth, you can use this cool sticker!   ### License Unsloth uses a dual-licensing model of Apache 2.0 and AGPL-3.0.
