Merged summary
TL;DR - PhiZero is a world model that predicts compact “physical-language” representations of state transitions before rendering them as video. This reason-then-render design makes physical dynamics explicit rather than leaving them implicit in pixel-space prediction.
- Learns its discrete physical-language representation from in-the-wild videos through self-supervision.
- Separates future-state reasoning from video generation to promote physically coherent evolution.
- Evaluated on both generation and understanding benchmarks.
- Supports interactive modeling, action-conditioned simulation, and zero-shot motion transfer.
