NVIDIA Cosmos 3: What Are These Open Models That Simulate the World
NVIDIA releases Cosmos 3, open models for interactive world simulation. Where the Cosmos line comes from and why AI simulates physical reality.
NVIDIA has released Cosmos 3, new open models for interactive world simulation. The announcement was published on November 5 on NVIDIA’s official blog at Hugging Face, the largest platform for publishing open AI models.
World models are AI systems that reproduce how a physical environment behaves: how a car moves, how an object falls, how a scene changes after an action. They are used to train robots and self-driving systems in simulation, not only through expensive real-world tests.
NVIDIA introduced the Cosmos family at CES in January 2025 as a platform of world models for “physical AI”, the company’s term for systems that act in the real world, such as robots and self-driving cars. The first models in the line came under the NVIDIA Open Model License, which allows commercial use.
KRAKOBIT has covered other open models that people can run themselves: the FreeToken engine, which runs 290B+ models on a gaming PC, is described in the FreeToken story.
