Do Physics Foundation Models Learn Generalizable Physics? A Bias-Aware Benchmark Across Physical Regimes and Distribution Shifts
Researchers benchmarked five physics foundation models across 8 physical dynamics and 25 test regimes, revealing that current models function as conditional rather than universal generalists. The study demonstrates that model performance heavily depends on physical regime, temporal scale, and distribution shifts, with pretraining and scaling unable to reliably overcome these limitations.
