NVIDIA opens a Cosmos-based surgical video simulator
NVIDIA released Cosmos3-H-Dreams, a generative research simulator trained on cholecystectomy video and robot kinematics. The system adapts a 16-billion-parameter world model to 28 action dimensions and includes code, checkpoints and recipes; NVIDIA says a distilled configuration can run in real time on one RTX PRO 6000.
Why it matters: An open action-conditioned simulator could let surgical-robot teams generate and replay controlled visual trajectories before using scarce or risky physical trials.
