NVIDIA Open-Sources Surgical World Model Cosmos3-H-Dreams, Enabling Real-Time Surgical Scene Generation on a Single GPU
NVIDIA has released and open-sourced the real-time generative surgical world model Cosmos3-H-Dreams, which can generate surgical scenes in real time based on robot operation instructions, simulating instrument movement, tissue retraction, and deformation. The model is built on the 16-billion-parameter Cosmos3-H-Embodied-Nano, with training data comprising approximately 526 minutes of real surgical video selected from 4,792 surgical recordings, and it supports 28-dimensional action input. Using teacher-student distillation and the FlashDreams streaming inference framework, the model requires only a single NVIDIA RTX PRO 6000 GPU for real-time interaction, and two student model versions with 4-step and 2-step denoising have been open-sourced.
