Self-Play Preference Optimization for Language Model Alignment (https://arxiv.org/abs/2405.00675)
Llama-3-Instruct-8B-SPPO-Iter2
This model was developed using Self-Play Preference Optimization at iteration 2, based on the meta-llama/Meta-Llama-3-8B-Instruct 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.
