NVIDIA GTC 2025: Cosmos Transfer WFMs, Open Physical AI Dataset, and Isaac GR00T N1 Open Models

AI Impact Summary

NVIDIA unveils three open-capability releases at GTC 2025: Cosmos Transfer as a World Foundation Model with multicontrols, an Open Physical AI Dataset, and Isaac GR00T N1 as the first open humanoid reasoning foundation model. Cosmos Transfer uses per-sensor ControlNets and adaptive spatiotemporal control maps to produce controllable, photorealistic world sequences and pairs with Omniverse for scalable synthetic data generation. The Open Physical AI Dataset delivers 15 TB of robotics data, 320,000 trajectories, and up to 1,000 OpenUSD assets to support post-training of Cosmos Predict and related WFMs. Isaac GR00T N1 employs a dual-system architecture for multimodal humanoid manipulation and is available as GR00T N1-2B on Hugging Face, enabling cross-robot embodiment and broader research use.
