Generative Critics Proposed for Value Modeling in LLM Reinforcement Learning

A cross-listed arXiv paper revisits learned value models, which are often avoided in LLM reinforcement learning, and proposes using generative critics in their place. The approach targets the credit assignment problem by enabling fine-grained advantage estimation in the style of classical actor-critic methods during RL training.
