VerifiedProcess Reward Models (PRM) shift toward evaluating the reasoning process rather than the final answer, and have already demonstrated significant advantages in the domain of mathematical reasoning.83% similarVerifiedA Process Reward Model (PRM) scores each intermediate step in a reasoning chain, as distinct from an Outcome Reward Model (ORM), which evaluates only the correctness of the final answer.75% similarVerifiedIn 2023, OpenAI published the paper "Let's Verify Step by Step," which systematically demonstrated the superiority of process reward models (PRM) in mathematical reasoning tasks.73% similarUnverifiedThere is a qualitative gap between the currently popular evaluation benchmarks GSM8K and MATH and frontier research-level mathematical reasoning70% similarUnverified在代码语料比例更高的混合数据集上训练的模型，在数学推理基准（如MATH、GSM8K）上的表现显著优于纯自然语言训练的同规模模型，这一结论获斯坦福大学和MIT的多项研究证实70% similar
