RLHFlow/Llama3.1-8B-PRM-Mistral-Data

This is a process-supervised reward (PRM) trained on Mistral-generated data from the project RLHFlow/RLHF-Reward-Modeling

The model is trained from meta-llama/Llama-3.1-8B-Instruct on RLHFlow/Mistral-PRM-Data for 1 epochs. We use a global batch size of 32 and a learning rate of 2e-6, where we pack the samples and split them into chunks of 8192 token.
