## Summary

NVIDIA releases four open-weight Cosmos 3 Nano checkpoints for interactive world simulation and multi-sensor driving scenes, each with 16B trainable parameters. The models include Cosmos3-Nano-Transfer-Auto for multi-view driving data, Cosmos3-Nano-Sim-Auto for streaming camera and LiDAR observations, Cosmos3-Nano-Sim-Transfer for simulator-controlled video, and Cosmos3-Nano-Sim-Bimanual for action-conditioned robot video. The checkpoints use the OpenMDW1.1 license, which permits commercial and non-commercial use under its terms.
