VeriPhy: Agentic Physical Reasoning for World Model Evaluation and Refinement

Wenzhuo Xu, Yuchen Zhu, Chongjian Ge +8

Visual fluency in generated video does not imply physical reliability, and a scalar quality score alone is incapable of indicating the obligation a clip violates or the moment it f…
