NVIDIA has released [Cosmos 3](https://huggingface.co/blog/nvidia/cosmos-interactive-world-simulation), the latest generation of its open model family aimed at interactive world simulation and video generation. The release continues NVIDIA's push to make world models — systems that can generate and extend visual environments — available to the broader developer community rather than keeping them locked inside proprietary stacks.

Cosmos 3 supports both text-to-video and image-to-video generation, meaning developers can seed a simulation from a written prompt or an existing frame and have the model produce coherent video continuations. The "interactive" framing is the notable shift: rather than treating generation as a one-shot output, the models are oriented toward worlds that can evolve in response to input.

## Why it matters

World models are increasingly central to robotics, autonomous systems, and simulation-heavy training pipelines, where generating realistic, controllable environments is often more practical than collecting real-world data. Making these capabilities openly available lowers the barrier for teams that want to build on top of them.

- Text-to-video and image-to-video generation in one family
- Focus on interactive, simulatable worlds rather than static clips
- Released as open models under NVIDIA's own license terms

As with prior NVIDIA open releases, the license is NVIDIA-specific rather than a standard permissive license, so teams should read the terms carefully before building commercial products. Full details and access are available through NVIDIA's [announcement on Hugging Face](https://huggingface.co/blog/nvidia/cosmos-interactive-world-simulation).
