PhiZero: A World Model Built Around Physical Language
NLPR, Institute of Automation, Chinese Academy of Sciences
PhiZero learns a compact discrete 'physical language' representing world-state transitions from unlabeled in-the-wild video, then uses a reason-then-render paradigm to infer future world evolution as a physical-language sequence before rendering it into video.
