The commercial-use license and adaptation recipes make the release usable inside company simulation stacks. NVIDIA added four open-weight Cosmos 3 Nano checkpoints to [Hugging Face](https://huggingface.co/blog/nvidia/cosmos-interactive-world-simulation?ref=runtimewire) on November 5th, 2026, extending the Cosmos 3 family into streaming driving simulation and action-conditioned robot video. The four releases are post-trained versions of Cosmos 3 Nano, each with 16B trainable parameters, released under OpenMDW 1.1 terms that permit commercial and non-commercial use.… When you purchase through links in our articles, [we may earn a small commission](https://runtimewire.com/affiliate-monetization-standards).
