unslothai/unsloth
Fine-tuning & Reinforcement Learning for LLMs. 🦥 Train OpenAI gpt-oss, DeepSeek, Qwen, Llama, Gemma, TTS 2x faster with 70% less VRAM.
Implements custom Triton kernels and mathematical optimizations for accelerated training across modalities (text, vision, audio, embeddings), while supporting full fine-tuning, reinforcement learning, and multi-bit quantization (4-bit, 16-bit, FP8). Provides both Unsloth Studio (web UI for Windows/Linux/macOS with visual data recipe workflows) and Unsloth Core (Python library integrating with PyTorch/Hugging Face), with built-in support for 500+ models and export to GGUF/safetensors formats.
