NVIDIA's GTC 2025 Announcement for Physical AI Developers: New Open Models and Datasets
Hugging Face Blog
NVIDIA released three open-source tools for physical AI development at its GTC 2025 conference: Cosmos Transfer (a 7 billion parameter world foundation model), a 15 terabyte physical AI dataset with 320,000 robotics trajectories, and Isaac GR00T N1, an open foundation model for humanoid robot reasoning. The Cosmos Transfer model uses multimodal controls including 3D bounding boxes, depth maps, and trajectory maps to generate photorealistic video sequences for synthetic data generation. Developers can now post-train these models on custom datasets to build specialized robotics and autonomous vehicle systems.
