Principia: A Benchmark Testing Whether Video Models Grasp Physics via Pendulum Dependencies
anand_bhattad · x · 2026-09-06
varunvarmat introduces Principia, a benchmark testing whether video models truly understand physics. The key idea: physical understanding requires capturing dependencies between the physical quantities that govern the real world — e.g., does a model know a pendulum's period depends on its length? Controlled synthetic scenarios like this probe whether video models memorize visual distributions or actually learn physical dependencies.
