unsloth 2026.3.5

2-5X faster training, reinforcement learning & finetuning

Run and train AI models with a unified local interface.

Features • Quickstart • Notebooks • Documentation • Discord

Unsloth Studio lets you run and train models for text, audio, embedding, vision and more. Available 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 works on Windows, Linux, WSL and macOS.

• CPU: Supported for chat inference only
• NVIDIA GPUs: Training works on RTX 30/40/50, Blackwell, DGX Spark, DGX Station and more
• macOS: Currently supports chat only; MLX training is coming very soon
• Multi-GPU: Available now, with a major upgrade on the way

Windows, MacOS Linux or WSL:

git clone https://github.com/unslothai/unsloth.git
cd unsloth
pip install -e .
unsloth studio setup
unsloth studio -H 0.0.0.0 -p 8888

Use our Docker image unsloth/unsloth container. Read our Docker Guide.

Git from source

git clone https://github.com/unslothai/unsloth.git
cd unsloth
pip install -e .
unsloth studio setup
unsloth studio -H 0.0.0.0 -p 8888

Unsloth Core (code-based)

Windows, Linux, WSL

pip install unsloth

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.

AMD, Intel

For RTX 50x, B200, 6000 GPUs: pip install unsloth. Read our guides for: Blackwell and DGX Spark.
To install Unsloth on AMD and Intel GPUs, follow our AMD Guide and Intel Guide.
