GAUGE: A Measurement-Grounded Benchmark for Physical Fidelity in Simulation Engines and Video World Models
A new real-world-grounded benchmark shows that physics engines and video world models each fail differently, with video models often fitting the shape of a physical law while recovering wrong parameters.
