Abstract 摘要

World models are becoming a central substrate for Physical AI, yet their current development is differentiating across representational, generative, interactive, and unified understandinggenerationprediction world models.

While these paradigms have advanced abstract world reasoning, high-fidelity visual generation, interactive simulation, and embodied world-action modeling, none alone provides the deployable, long-horizon, control-sufficient state required by embodied agents. We intr
