PhysVista tests 16 VLMs with a seeing–reasoning–assessment loop: perception holds up, physical reasoning and plausibility scoring lag
PhysVista introduces a benchmark that links physical state perception, physical dynamics reasoning, and physical plausibility assessment into a closed loop, includes both real-world and AI-generated videos, and evaluates 16 VLMs, finding that models do relatively better on observable state perception but fall short on physical dynamics prediction, counterfactual reasoning, and fine-grained plausibility scoring and ranking, with performance generally better on real-world than generated videos.
