About
SPPO (Self-Play Preference Optimization) is an open-source project offering the official implementation of a novel self-play framework for language model alignment. It introduces a new learning objective, the SPPO loss, designed to efficiently fine-tune large language models. The project provides code and pre-trained models, including iterations for Mistral-7B, Llama-3-8B, and Gemma-2-9B, demonstrating significant performance enhancements on benchmarks like AlpacaEval 2.0. SPPO is theoretically grounded, ensuring convergence to a Nash equilibrium, and empirically validated through extensive evaluations. It's built upon the alignment-handbook codebase and utilizes vllm for generation and PairRM for ranking, making it a robust solution for researchers and developers working on advanced language model alignment techniques.
