1、2026-6-22Cosmos 3:Omnimodal World Models for Physical AINVIDIA1AbstractWe introduce Cosmos 3,a family of omnimodal world models designed to jointly process and generate lan-guage,image,video,audio,and action sequences within a unified mixture-of-transformers architecture.By supporting highly flexibl

2、e input-output configurations,Cosmos 3 seamlessly unifies critical modalitiesfor Physical AIeffectively subsuming vision-language models,video generators,world simulators,andworld-action models into a single framework.Our evaluation demonstrates that Cosmos 3 establishesa new state-of-the-art across

3、 a diverse suite of understanding and generation tasks,demonstratingomnimodal world models as scalable,general-purpose backbones for embodied agents.Our post-trainedCosmos 3 models were ranked as the best open-source Text-to-Image and Image-to-Video models by Arti-ficial Analysis,and the best policy
