Video Models Can Fool Your Eyes but Not Physics: New Benchmark Exposes the Gap

A Google DeepMind benchmark called Physics-IQ tests video generation models on real-world physical understanding — and finds that even the most visually convincing models score poorly on mechanics, fluids, and object interactions.

A new benchmark from Google DeepMind, highlighted by @rohanpaul_ai, tests video generation models on whether they actually understand physics — not just whether their outputs look realistic. The results are humbling: OpenAI's Sora produces videos that are hardest for humans to distinguish from real footage, but scores poorly on physical accuracy across categories like mechanics, fluid dynamics, and rigid body interactions.
