NVIDIA Releases Four Open-Weight Cosmos 3 Nano Models for Interactive World Simulation

NVIDIA has added four new open-weight checkpoints to its Cosmos 3 Nano model family for interactive world simulation and multi-sensor multi-view driving scenes. All models have 16B trainable parameters and are released under OpenMDW1.1, permitting commercial and non-commercial use. The checkpoints support driving data generation, synchronized camera and LiDAR streaming, simulator-to-video rendering, and bimanual robot action-to-video prediction. Requirements include Linux, an NVIDIA GPU, Docker, and NVIDIA Container Toolkit.
