Study links LLM agent failures in new environments to world-modeling gaps

A new arXiv paper examines why LLM-based agents often stop improving when placed in unfamiliar settings, identifying a failure mode the authors call exploration collapse. Under reinforcement learning, the researchers argue, the agent's world model fails to align with the new environment's state distribution, causing exploration to break down. The work characterizes this phenomenon from a world-modeling perspective to explain when and why such collapse occurs.
