Overview
- GenPRM introduces a generative process reward model that performs step-by-step reasoning with code verification
- Addresses three key limitations in existing Process Reward Models (PRMs)
- Uses Relative Progress Estimation (RPE) and rationale synthesis for high-quality supervision
- Achieves superior performance with only 23K training examples
- A 1.5B parameter version outperforms GPT-4o on ProcessBench
- A 7B parameter version surpasses Qwen2.5-Math-PRM-72B
- Serves effectively as a critic model for improving other language models
Plain English Explanation
Imagine you're trying to solve a difficult math problem. You'd probably work through it step by step, checking your work along the way. This is exactly what the researchers behind GenPRM are teaching AI systems to do.
Traditional AI systems that verify reasoning (called Proces...
