[NVIDIA Cosmos 3 Physical AI World Model Officially Available for Download Today, Two Versions Launched on HuggingFace] According to monitoring by Beating, NVIDIA has officially made the model weights for the Cosmos 3 world model available for download today. The initial release includes two versions: Super (64.6 billion parameters) and Nano (15.7 billion parameters), both of which are now available on HuggingFace (no gating, direct download) and build.(nvidia.com). They also support deployment in the form of NVIDIA NIM microservices. Cosmos 3 is positioned as a foundational omnimodal world model for physical AI, built on a new Mixture of Transformers architecture. It natively understands and generates text, images, videos, environmental sounds, and actions. The Super version is designed for post-training robotics and autonomous driving models requiring the highest physical precision, while the Nano version targets low-latency scenarios for high-quality video and action inference. Additionally, an Edge version (designed for real-time inference on edge devices) is expected to be released soon. NVIDIA claims that Cosmos 3 is 'the world's first fully open omnimodal model,' allowing developers to freely download, fine-tune, and convert it into proprietary models. [Original Link]
