This is a process-supervised reward (PRM) trained on Mistral-generated data from the project [RLHFlow/RLHF-Reward-Modeling](https://github.com/RLHFlow/RLHF-Reward-Modeling)

The model is trained from [meta-llama/Llama-3.1-8B-Instruct](https://huggingface.co/meta-llama/Llama-3.1-8B-Instruct) on [RLHFlow/Deepseek-PRM-Data](https://huggingface.co/datasets/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/Online-RLHF/blob/main/math/llama-3.1-prm.yaml .


## BoN evaluation result for Mistral generator:

| Model      | Method     | GSM8K     | MATH |
| ------------- | ------------- | ------------- | -------- |
| Mistral-7B | Pass@1 | 77.9 |  28.4   |
| Mistral-7B | Majority Voting@1024 | 84.2 | 36.8  |
