研究人员开发了VRPRM，一种新颖的过程奖励模型，它利用视觉推理来增强大型语言模型（LLM）推理步骤的细粒度评估。这种方法显著降低了此类模型训练通常需要的数据标注成本。与传统的非思考PRM相比，VRPRM表现出更优越的性能，仅用一小部分训练数据就取得了实质性改进。 AI
影响 这项研究提供了一种更有效的LLM训练方法，有望降低成本并提高推理能力。

arXiv:2508.03556v3 Announce Type: replace Abstract: Process Reward Model (PRM) is widely used in the post-training of Large Language Model (LLM) because it can perform fine-grained evaluation of the reasoning steps of generated content. However, most PRMs lack long-term reasoning…
Unsupervised reward models eliminate the need for human annotations in training by leveraging language model next-token probabilities to identify erroneous reasoning steps and improve policy optimization in reinforcement learning.
