WorldAlign: Decoupled 4D Reward for World-Consistent Video Generation

Jing He, Kaixin Ding, Xingye Tian et al. · 2026

Faithful visual world simulation requires generated videos to maintain 4D world consistency, encompassing both static and dynamic consistency. Static consistency requires coherent 3D structure in static environments across viewpoints, while dynamic consistency requires plausible subject motion and consistent appearance …

Physis-Lang: Self-Evolving Language as a Physical Representation for Video World Model

Liming Lu, Xianzheng Ma, Wenkun He et al. · 2026

Video world models are expected to predict how the physical world evolves, yet they often produce visually plausible videos that violate basic physical principles. Existing approaches commonly assume that natural language is insufficient to represent the physical knowledge required for reliable generation, and therefor …
