NVIDIA Cosmos 3 has been open-sourced, with 64.6 billion parameters released directly. Physical AI is about to change the game.

CryptoWorld News reports that NVIDIA has officially opened the download of the Cosmos 3 physical AI world model weights today. The first batch released includes two versions: super (64.6 billion parameters) and nano (15.7 billion parameters), both of which are now available on HuggingFace (no gating, can be downloaded directly) and build.nvidia.com, and they also support deployment in the form of NVIDIA NIM microservices. Cosmos 3 is positioned as a full-modal (omnimodel) world foundation model for physical AI, based on a brand-new hybrid Transformer architecture (mixture of transformers), with native understanding and generation of text, images, videos, environmental sounds, and actions. The super version is for post-training robotics and autonomous driving models that require the highest physical accuracy, while the nano version is specifically for high-quality video and action reasoning of
