ProPhy: Progressive Physical Alignment for Dynamic World Simulation

ArXi:2512.05564v2 Announce Type: replace Recent advances in video generation have shown remarkable potential for constructing world simulators. However, current models still struggle to produce physically consistent results, particularly when handling large-scale or complex dynamics. This limitation arises primarily because existing approaches respond isotropically to physical prompts and neglect the fine-grained alignment between generated content and localized physical cues.
