# Model Card for Model ID

<!-- Provide a quick summary of what the model is/does. -->
**PPO-M** (PPO with Calibrated Reward Modeling) is an RLHF algorithm to mitigate verbalized overconfidence in RLHF-trained Large Language Models.
We calibrate the reward modeling process by augmenting the binary pairwise ranking dataset with explicit confidence scores, and encourages the
reward model to align confidence levels with response quality.
Please refer to our preprint ([Taming Overconfidence in LLMs: Reward Calibration in RLHF](https://arxiv.org/abs/2410.09724)) and [repo](https://github.com/SeanLeng1/Reward-Calibration) for more details.



## Model Details


### Model Description

<!-- Provide a longer summary of what this model is. -->

We train a calibrated reward model from [OpenRLHF/Llama-3-8b-rm-mixture](https://huggingface.co./OpenRLHF/Llama-3-8b-rm-mixture) on our [https://huggingface.co./datasets/HINT-lab/calibration_preference_mixture_final-v0.1) dataset.
