About
NVIDIA Cosmos 3 is the world's first fully open omnimodel for physical AI, built on a Mixture-of-Transformers (MoT) architecture that combines a vision-language autoregressive Reasoner tower with a diffusion-based Generator tower. The family natively understands and generates text, images, video, ambient sound, and robot action sequences with physics-grounded accuracy. Designed for robotics, autonomous vehicles, and smart infrastructure; supports synthetic data generation, robot policy training, world simulation, and VLM reasoning. Announced at Computex 2026 on 2026-06-01; model weights released 2026-05-31. GitHub: https://github.com/nvidia/cosmos.
