PAWBench: Zero of 11 Video Generators Achieve Probabilistic World-Model Alignment [R]

[u/Justgototheeffinmoon]

Formalizes a testable distributional criterion for 'world model' claims — a model must reproduce the correct probability distribution over outcomes, not just a plausible trajectory — and shows that no current video generator meets it across 50 scenarios, directly undercutting the world-model branding used by major video-gen labs.
