NVIDIA/MIT's Physis-Lang tops Physics-IQ leaderboard, +5.5 points via evolved captions

songhan_mit · x · 2026-09-30

NVIDIA, MIT and Oxford propose Physis-Lang, a self-evolving language representation for video world models. Captions are decomposed into cause, physical law and effect, and a physics-aware critic plus an agent iteratively refine shared captioning guidelines while the captioner stays fixed. The same representation spans data curation, training and inference. On Physics-IQ Verified it takes #1 and #2: Cosmos3-Super scores 48.2, beating the previous leader by 5.5 points; Cosmos3-Nano scores 43.3, surpassing the original Cosmos3-Super.
