Self-Play Preference Optimization for Language Model Alignment (https://arxiv.org/abs/2405.00675)
Gemma-2-9B-It-SPPO-Iter2
This model was developed using Self-Play Preference Optimization at iteration 2, based on the google/gemma-2-9b-it architecture as starting point. We utilized the prompt sets from the openbmb/UltraFeedback dataset, splited to 3 parts for 3 iterations by snorkelai/Snorkel-Mistral-PairRM-DPO-Dataset. All responses used are synthetic.
