A new study systematically evaluates four frontier video foundation models, V-JEPA 2.1, V-JEPA 2, VideoPrism, and VideoMAEv2, across five robustness axes relevant to their use as world models. The research finds that latent-prediction models consistently outperform others in feature discriminability, corruption robustness, fine-grained discrimination, occlusion robustness, and temporal direction encoding. Notably, a frozen V-JEPA 2 backbone demonstrated superior robustness on corruption and occlusion tasks compared to fully fine-tuned models, suggesting latent prediction's advantages for robust world modeling.
