NVIDIA Adds Four Open Cosmos 3 Models for World Simulation

NVIDIA released four open-weight checkpoints in its Cosmos 3 world-model family, each post-trained from Cosmos 3 Nano with 16 billion trainable parameters. Transfer-Auto generates multi-view driving data with varied weather, lighting, and time of day; Sim-Auto streams synchronized camera and LiDAR observations for driving simulation; Sim-Transfer converts simulator controls and a text prompt into video; and Sim-Bimanual predicts video from robot or camera actions. The checkpoints are available for download under OpenMDW1.1, which permits commercial and non-commercial use under its terms. NVIDIA also published a technical report, demos, and inference instructions; the models require Linux, an NVIDIA GPU, Docker, and the NVIDIA Container Toolkit.
