NVIDIA Releases Cosmos 3 Open Models for Interactive World Simulation

NVIDIA has released Cosmos 3, a new set of open-weight models on Hugging Face designed for interactive world simulation, enabling developers to generate physically plausible, controllable 3D environments from prompts or partial observations. The models are built to support robotics, autonomous vehicle training, and game simulation pipelines, extending the original Cosmos family with improved interactivity and scene controllability. Because the weights are openly available, developers can fine-tune Cosmos 3 for domain-specific simulation tasks without depending on a proprietary API. This is a significant release for anyone building synthetic data pipelines, sim-to-real robotics workflows, or interactive environment generators. The open release lowers the barrier for research teams and startups to access frontier-class world simulation capabilities.
