LLaMA-Factory: Unified Fine-Tuning for 100+ LLMs & VLMs
The landscape of Large Language Models (LLMs) and Vision Language Models (VLMs) is evolving at an unprecedented pace. As these models grow in complexity and capability, the need for efficient and accessible fine-tuning solutions becomes paramount. Enter LLaMA-Factory, an acclaimed open-source project that is redefining how developers and researchers approach model customization.
What is LLaMA-Factory?
LLaMA-Factory is a comprehensive, unified fine-tuning framework designed to simplify the process of adapting over 100 different LLMs and VLMs. Published as an ACL 2024 paper and boasting over 53,000 stars on GitHub, it provides a robust toolkit for efficiently molding pre-trained models to specific tasks or datasets. Its core strength lies in abstracting away much of the underlying complexity, offering both a zero-code command-line interface (CLI) and an intuitive Web UI (LlamaBoard) powered by Gradio.
Key Features and Benefits
LLaMA-Factory stands out with a rich set of features tailored for diverse AI development needs:
-
Extensive Model Support: The platform supports a vast array of popular models, including LLaMA, LLaVA, Mistral, Mixtral-MoE, Qwen, Gemma, ChatGLM, Phi, and many more. This broad compatibility ensures that users can work with their preferred or most suitable models.
-
Unified Training Approaches: From continuous pre-training and supervised fine-tuning (SFT) to advanced reinforcement learning from human feedback (RLHF) methods like PPO, DPO, KTO, and ORPO, LLaMA-Factory integrates multiple training paradigms. This flexibility allows for deep customization and performance optimization.
-
Efficient Resource Scaling: Tackle memory and computational constraints with sophisticated techniques like 16-bit full-tuning, freeze-tuning, and Parameter-Efficient Fine-Tuning (PEFT) methods such as LoRA and various 2/3/4/5/6/8-bit QLoRA optimizations via AQLM/AWQ/GPTQ/LLM.int8/HQQ/EETQ. This makes fine-tuning large models accessible even on more modest hardware.
-
Advanced Algorithms & Practical Tricks: The framework incorporates cutting-edge algorithms like GaLore, BAdam, APOLLO, DoRA, LongLoRA, and PiSSA, alongside practical optimizations such as FlashAttention-2, Unsloth, Liger Kernel, and NEFTune, ensuring top-tier performance and efficiency.
-
Versatile Task Handling: LLaMA-Factory isn't limited to simple text generation. It supports a wide range of tasks, including multi-turn dialogue, tool usage, image understanding, visual grounding, and audio recognition, making it ideal for multi-modal AI applications.
-
User-Friendly Interfaces: Whether you prefer scripting or a graphical interface, LLaMA-Factory has you covered. The
llamafactory-cliprovides powerful terminal commands, while the Gradio-powered Web UI offers a visual, interactive experience for training, evaluation, and inference. -
Accelerated Inference: Deploy your fine-tuned models with ease using integrated vLLM or SGLang workers, enabling faster and more concurrent inference through OpenAI-style APIs and Gradio UIs.
-
Comprehensive Experiment Monitoring: Keep track of your experiments closely with support for popular monitoring tools like LlamaBoard, TensorBoard, Wandb, MLflow, and SwanLab.
-
Industry Validation: Its adoption by major players like Amazon, NVIDIA, and Aliyun speaks volumes about LLaMA-Factory's reliability and practical utility in real-world scenarios.
