This is a model released for our paper: REBEL: Reinforcement Learning via Regressing Relative Rewards.

REBEL-OpenChat-3.5

This model is developed with REBEL based on OpenChat-3.5 with Starling-RM-7B-alpha as the reward model and Nectar dataset. The training code is available at https://github.com/ZhaolinGao/REBEL. We collect online generations during each iteration with a batch size of 32.
