About
SimPO (Simple Preference Optimization) is an open-source algorithm and codebase designed for fine-tuning large language models (LLMs) based on preferences, offering a simpler and more effective approach than traditional methods like DPO. A key differentiator is its reference-free reward mechanism, eliminating the need for a separate reference model. SimPO has demonstrated superior performance across benchmarks such as AlpacaEval 2, MT-Bench, and Arena-Hard under diverse settings. The repository provides code, released model checkpoints, and detailed guidance on hyperparameter tuning, including learning rate, beta, and gamma, to help users achieve optimal results. It also includes pre-trained models for Gemma and Llama3, showcasing its applicability to various LLM architectures.
