ms-swift: ModelScope framework for fine-tuning 600+ LLMs and 300+ MLLMs

ms-swift is an open-source Python framework from ModelScope supporting PEFT and full-parameter fine-tuning methods (CPT, SFT, DPO, GRPO) across 600+ LLMs and 300+ multimodal LLMs, including Qwen3, DeepSeek, Llama4, and others. The project has accumulated 14,487 GitHub stars and was accepted at AAAI 2025. It serves as a broad-coverage training harness for the current generation of open-weights frontier models.
