Streamlined tool for easily fine-tuning AI models

⭐ 12k+ stars 📜 Apache-2.0 🏷️ skill

Overview

Streamlined tool for easily fine-tuning AI models

✓ Comprehensive fine-tuning support: SFT, DPO, RLHF, and more in one tool
✓ YAML configuration makes complex training runs reproducible and shareable
✓ Integrates with Flash Attention 2, DeepSpeed, and FSDP for large-scale training
✓ Strong community adoption for Llama and Mistral model fine-tuning

✗ YAML configuration system has a learning curve — many options require documentation study
✗ Debugging training issues requires familiarity with the underlying HuggingFace stack
✗ Less beginner-friendly than Unsloth for quick single-model fine-tuning
