General Preference Modeling with Preference Representations for Aligning Language Models (https://arxiv.org/abs/2410.02197)

SPPO-Llama-3-8B-Instruct-GPM-2B

This model was developed using SPPO at iteration 3 and the General Preference representation Model (GPM) (specifically, using GPM-Gemma-2B), 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.
