What does PhyWorldBench test beyond ordinary physics (anti-physics prompts), how does its MLLM judge compare with humans, and did its numbers change between v1 and v3?

PhyWorldBench v3 (revised 26 May 2026) has 1,050 prompts over 10 physics categories (kinematics, interaction dynamics, energy, fluids and particles, lighting and shadows, deformation and others, plus human/animal motion and an Anti-Physics level) and scores videos with three-annotator Yes/No majority votes on semantic adherence (SA), physical commonsense (PC) and both. Twelve text-to-video models were scored; the best, Pika 2.0, reaches 0.262 on 'Both' and anti-physics prompts are far lower (0.000 to 0.042 for most). All twelve overall rows in Table 3 are identical between v1 (Jul 2025) and v3 by my own comparison, while v3 adds precision/recall tables and a CAP neutrality check. The authors' Context-Aware Prompt (CAP) judge reaches ROC-AUC 75.1 for physical commonsense versus 61.6 for plain GPT-o1.

Curator qualifications: Curator located the excerpted evidence in the work copies (automated prefix match) and spot-checked claim-critical figures by search. The five-vs-seven model-count inconsistency is kept. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
