Summary

NVIDIA has launched Cosmos 3, an open world foundation model and the "world's first fully open AI omnimodel," designed for physical AI applications. Unveiled on June 09, 2026, this system uses a mixture-of-transformers architecture to integrate vision reasoning, world generation, and action prediction. Cosmos 3 can process and create text, images, video, ambient sound, and actions with leading physics accuracy, aiming to reduce physical AI training times. It enables robots, autonomous vehicles, and vision agents to operate in real-world settings with limited training data. The platform includes new datasets for robotics, autonomous driving, and warehouse safety, alongside skills like neural scene reconstruction. Cosmos 3 Super, a variant, focuses on high-accuracy post-training for robotics and AVs, generating synthetic data for tasks like pick-and-place. Industry leaders like Doosan Robotics and Li Auto are already adopting the platform.

Key takeaway
