Cosmos 3: Omnimodal World Models for Physical AI

arXiv:2606.02800v1 Announce Type: cross Abstract: We introduce Cosmos 3, a family of omnimodal world models designed to jointly process and generate language, image, video, audio, and action sequences within a unified mixture-of-transformers architecture. By supporting highly flexible input-output configurations, Cosmos 3 seamlessly unifies critical modalities for Physical AI -- effectively subsuming vision-language models, video generators, world simulators, and world-action models into a single framework. Our evaluation demonstrates that Cosmos 3 establishes a new state-of-the-art across a d

Why this matters
Why now

The announcement of Cosmos 3 represents a significant step towards unified omnimodal AI models, building on recent advances in mixture-of-transformers architectures.

Why it’s important

A single framework capable of processing and generating diverse modalities could accelerate the development of truly intelligent and adaptable Physical AI systems, with broad implications for automation and robotics.

What changes

The fragmented landscape of specialized AI models (vision-language, video generators, world simulators) begins to converge into a more generalized, omnimodal architecture.
