What RLHFlow says about Llama3.1-PRM-Deepseek-Data

Read the model card

This is a process-supervised reward (PRM) from the project RLHFlow/RLHF-Reward-Modeling

The model is trained from meta-llama/Llama-3.1-8B-Instruct on RLHFlow/Deepseek-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. See more training details at https://github.com/RLHFlow/RLHF-Reward-Modeling/tree/main/math-rm.
