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 and deep thinking capabilities. On the other hand, although a few works have tried to introduce Chain-of-Thought (CoT) capability into PRMs, the annotation cost of CoT-PRM data is too expensive to play a stable role in various tasks. To address the above challenges, we propose VRPRM, a process reward model via visual
The continuous drive to enhance the reasoning capabilities and cost-effectiveness of AI models like LLMs motivates this research, addressing current limitations in reward modeling.
Improving Process Reward Models (PRMs) is crucial for developing more robust and autonomously reasoning AI, impacting the quality and reliability of generated content and ultimately the efficiency of AI systems.
The proposed VRPRM aims to provide PRMs with better long-term reasoning and deeper thinking capabilities while reducing the high annotation costs associated with previous Chain-of-Thought (CoT) PRMs.
