NVIDIA Cosmos 3 Physical AI World Model officially opens for download today, with two versions available on Hugging Face
CoinWorld News: NVIDIA today officially opened the download of the model weights for Cosmos 3, its physical AI world model. The first batch released includes two versions—super (646亿 parameters) and nano (157亿 parameters). Both are now available on HuggingFace (no gating; can be downloaded directly) and build.nvidia.com, and they also support deployment as NVIDIA NIM microservices.
Cosmos 3 is positioned as a fully multimodal (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 aimed at post-training robotics and autonomous driving models that require the highest physical accuracy, while the nano version is designed for low-latency scenarios involving high-quality video and action reasoning. In addition, an edge version (for real-time inference on edge devices) is expected to be released soon.
NVIDIA says Cosmos 3 is the “world’s first fully open multimodal model.” Developers can freely download it, post-train it, and convert it into proprietary models.
