Cosmos 3

NVIDIA's physical-AI flagship, billed as the "world's first fully open omnimodel": a unified Mixture-of-Transformers combining autoregressive and diffusion generation across text, image, video, audio, and action, trained on ~20T multimodal tokens. Ships in Super and Nano variants with a "Cosmos Coalition" of robotics and simulation partners. Launched at GTC Taipei June 1 (backfilled); the technical report was revised through late June. The companion Cosmos3-DROID release repackages the DROID robot corpus in LeRobotDataset v3.0 format — 71,907 episodes / 22M frames / 707GB under OpenMDW-1.1.
