Run and train AI models with a unified local interface.

Features • Quickstart • Notebooks • Documentation • Discord

Unsloth Studio (Beta) lets you run and train text, audio, embedding, vision 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 models to GGUF, 16-bit safetensors and other formats.
• Tool calling: Support for self-healing tool calling and web search
• Code execution: lets LLMs run code, data and verify results so answers are more accurate.
• Auto-tune inference parameters and customize chat templates.
• Upload images, audio, PDFs, code, DOCX and more file types to chat with.

Training

• Train 500+ models up to 2x faster with up to 70% less VRAM, with no accuracy loss.
• Supports full fine-tuning, pretraining, 4-bit, 16-bit and, FP8 training.
• Observability: Monitor training live, track loss and GPU usage and customize graphs.
• Data Recipes: Auto-create datasets from PDF, CSV, DOCX etc. Edit data in a visual-node workflow.
• Reinforcement Learning: The most efficient RL library, using 80% less VRAM for GRPO, FP8 etc.
• Multi-GPU training is supported, with major improvements coming soon.

⚡ Quickstart

Unsloth can be used in two ways: through Unsloth 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 inference only
• NVIDIA: Training works on RTX 30/40/50, Blackwell, DGX Spark, Station and more
• macOS: Currently supports chat only; MLX training is coming very soon
• AMD: Chat works. Train with Unsloth Core. Studio support is coming soon.
• Coming soon: Training support for Apple MLX, AMD, and Intel.
• Multi-GPU: Available now, with a major upgrade on the way

MacOS, Linux, WSL:

For MacOS, ensure you have cmake installed. If not, run brew install cmake.

curl -fsSL https://raw.githubusercontent.com/unslothai/unsloth/main/install.sh | sh

If you don't have curl, use wget:

wget -qO- https://raw.githubusercontent.com/unslothai/unsloth/main/install.sh | sh

Or manually:

curl -LsSf https://astral.sh/uv/install.sh | sh
uv venv unsloth_studio --python 3.13
source unsloth_studio/bin/activate
uv pip install unsloth --torch-backend=auto
unsloth studio setup
unsloth studio -H 0.0.0.0 -p 8888

Then to launch every time:

source unsloth_studio/bin/activate
unsloth studio -H 0.0.0.0 -p 8888

Windows PowerShell (One time):

irm https://raw.githubusercontent.com/unslothai/unsloth/main/install.ps1 | iex

Or manually:

winget install -e --id Python.Python.3.13
winget install --id=astral-sh.uv  -e
uv venv unsloth_studio --python 3.13
.\unsloth_studio\Scripts\activate
uv pip install unsloth --torch-backend=auto
unsloth studio setup
unsloth studio -H 0.0.0.0 -p 8888

Then to launch every time:

.\unsloth_studio\Scripts\activate
unsloth studio -H 0.0.0.0 -p 8888

Docker

Use our Docker image unsloth/unsloth container. Run:

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

Nightly Install - MacOS, Linux, WSL:

curl -LsSf https://astral.sh/uv/install.sh | sh
git clone --filter=blob:none https://github.com/unslothai/unsloth.git unsloth_studio
cd unsloth_studio
uv venv --python 3.13
source .venv/bin/activate
uv pip install -e . --torch-backend=auto
unsloth studio setup
unsloth studio -H 0.0.0.0 -p 8888

Then to launch every time:

cd unsloth_studio
source .venv/bin/activate
unsloth studio -H 0.0.0.0 -p 8888

Nightly Install - Windows:

Run in Windows Powershell:

winget install -e --id Python.Python.3.13
winget install --id=astral-sh.uv  -e
git clone --filter=blob:none https://github.com/unslothai/unsloth.git unsloth_studio
cd unsloth_studio
uv venv --python 3.13
.\.venv\Scripts\activate
uv pip install -e . --torch-backend=auto
unsloth studio setup
unsloth studio -H 0.0.0.0 -p 8888

Then to launch every time:

cd unsloth_studio
.\.venv\Scripts\activate
unsloth studio -H 0.0.0.0 -p 8888

Unsloth Core (code-based)

Linux, WSL

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. You can use the same Docker image as Unsloth Studio.
