Developed by axolotl-ai-cloud, this Python-based tool provides a streamlined approach to customizing models, supporting a wide array of architectures and advanced training techniques. With over 12,000 stars on GitHub, Axolotl has become a popular choice for those looking to efficiently adapt LLMs for specific tasks and datasets.\n\nKey features include support for numerous models from the Hugging Face Hub, multimodal training capabilities for vision-language and audio models, and a variety of training methods such as full fine-tuning, LoRA, QLoRA, and advanced preference tuning techniques like DPO and GRPO. Its emphasis on easy configuration via YAML files and extensive performance optimizations ensures efficient and scalable training across different hardware setups.\n\n## Installation\n\nGetting started with Axolotl is straightforward. The project recommends using `uv` for package management and provides clear steps for setting up your environment.\n\n**Requirements**:\n\n*   NVIDIA GPU (Ampere or newer for `bf16` and Flash Attention) or AMD GPU\n*   Python >=3.11 (3.12 recommended)\n*   PyTorch ?2.11.0\n\n**Steps**:\n\n1.  **Install `uv` (if not already installed)**:\n    bash\n    curl -LsSf https://astral.sh/uv/install.sh | sh\n    # Restart your shell after installation\n    \n\n2.  **Set `UV_TORCH_BACKEND` (change depending on your system)**:\n    bash\n    export UV_TORCH_BACKEND=cu130\n    \n\n3.  **Create a new virtual environment and activate it**:\n    bash\n    uv venv --python 3.12\n    source .venv/bin/activate\n    \n\n4.  **Install PyTorch and Axolotl**:\n    bash\n    uv pip install torch==2.12.0 torchvision\n    uv pip install --no-build-isolation axolotl[deepspeed]\n    \n\n5.  **Download example configurations (optional)**:\n    bash\n    axolotl fetch examples\n    axolotl fetch deepspeed_configs # OPTIONAL\n    \n\n**Using Docker**:\n\nFor an even simpler setup, you can use the official Docker image:\n\nbash\ndocker run --gpus '\"all\"' --ipc=host --rm -it axolotlai/axolotl:main-latest\n\n\nMore detailed installation approaches are available in the [official documentation](https://docs.axolotl.ai/docs/installation.html).\n\n## Examples\n\nOnce Axolotl is installed, you can quickly fine-tune a model using the provided examples.\n\n1.  **Fetch Axolotl examples**:\n    bash\n    axolotl fetch examples\n    # Or, specify a custom path\n    axolotl fetch examples --dest path/to/folder\n    \n\n2.  **Train a model using LoRA**:\n    bash\n    axolotl train examples/llama-3/lora-1b.yml\n    \n\nFor a more comprehensive guide, refer to the [Getting Started Guide](https://docs.axolotl.ai/docs/getting-started.html).\n\n## Why Use Axolotl?\n\nAxolotl stands out as a premier tool for LLM fine-tuning due to its extensive feature set and focus on performance and usability:\n\n*   **Broad Model Compatibility**: Supports a vast range of models, including GPT-OSS, LLaMA, Mistral, Mixtral, Pythia, and many others available on the Hugging Face Hub.\n*   **Advanced Training Methods**: Offers a comprehensive suite of training techniques, from full fine-tuning and LoRA/QLoRA to GPTQ, QAT, Preference Tuning (DPO, IPO, KTO, ORPO), RL (GRPO, GDPO), and Reward Modelling.\n*   **Multimodal Capabilities**: Enables fine-tuning of vision-language models (VLMs) like LLaMA-Vision, Qwen2-VL, LLaVA, and audio models such as Voxtral, with support for image, video, and audio data.\n*   **Performance Optimizations**: Integrates cutting-edge optimizations like Multipacking, Flash Attention (2/3/4), Xformers, Sequence Parallelism (SP), LoRA optimizations, and multi-GPU/multi-node training (FSDP1, FSDP2, DeepSpeed, Torchrun, Ray) to maximize training efficiency.\n*   **Simplified Workflow**: Utilizes a single YAML configuration file for the entire fine-tuning pipeline, covering dataset preprocessing, training, evaluation, quantization, and inference.\n*   **Cloud Ready**: Provides Docker images and PyPI packages for seamless deployment on various cloud platforms and local hardware.\n*   **AI Agent Support**: Includes built-in documentation optimized for AI coding agents, making it easier to integrate with tools like Claude Code, Cursor, and Copilot.\n\n## Links\n\n*   **GitHub Repository**: [https://github.com/axolotl-ai-cloud/axolotl](https://github.com/axolotl-ai-cloud/axolotl \"Axolotl GitHub Repository\" target=\"_blank\")\n*   **Official Documentation**: [https://docs.axolotl.ai/](https://docs.axolotl.ai/ \"Axolotl Documentation\" target=\"_blank\")\n*   **Discord Community**: [https://discord.com/invite/HhrNrHJPRb](https://discord.com/invite/HhrNrHJPRb \"Axolotl Discord\" target=\"_blank\")\n*   **PyPI Package**: [https://pypi.org/project/axolotl/](https://pypi.org/project/axolotl/ \"Axolotl PyPI Package\" target=\"_blank\")","metrics":{"detailViews":2,"githubClicks":0},"dates":{"published":null,"modified":"2026-07-07T15:15:22.000Z"}}
