NVIDIA ships Cosmos3-Super, a 64B physical-AI world model.

Per NVIDIA, it splits into a 32B reasoner plus 32B generator, coupling action trajectories with synchronized video and audio. It natively produces text, images, video, ambient sound, and physical actions, and ranks first among open-weight options on several physical benchmarks. For robotics and sim-to-real data generation, it's a notable open foundation rather than another chat model. The backdrop is Jensen Huang's GTC Paris keynote anchoring VivaTech this week, where physical and sovereign AI are the throughlines.
