NVIDIA releases Cosmos3-H-Embodied-Nano and Cosmos3-H-Dreams surgical robotics world models
NVIDIA published two surgical robotics models on Hugging Face whose model cards give a release date of October 20, 2026, both under the NVIDIA Open Model License Agreement. The Cosmos3-H-Embodied-Nano card describes Cosmos3-Nano post-trained on the Open-H-Embodiment surgical robotics data jointly for forward dynamics, inverse dynamics and policy, so one checkpoint can predict robot actions and endoscopic video. The Cosmos3-H-Dreams card describes a real-time, action-conditioned surgical world model for the CMR Surgical Versius system, built on Cosmos3-H-Embodied-Nano and distilled into a few-step autoregressive student that generates endoscopic video from a camera frame and robot commands. Both cards say the Cosmos3-Nano architecture they inherit includes a Qwen3-VL-8B reasoning tower, and the cards describe intended uses in simulation, policy evaluation and synthetic data generation before use on a physical system. USASI has not tested these models.
