NVIDIA releases four open Cosmos 3 Nano models for world simulation

The models aim to address gaps in simulation environments for autonomous driving and robotics. Transfer-Auto generates multi-view driving data with variable weather and lighting, while Sim-Auto streams synchronized video and LiDAR for real-time driving simulations. Sim-Transfer turns physics simulator controls into photorealistic video, and Sim-Bimanual predicts visual outcomes from robot or camera actions. NVIDIA provides technical reports, notebooks, and open skills for inference, though users need Linux, an NVIDIA GPU, Docker, and Container Toolkit to run them. The focus now shifts to evaluating how well these models support policy learning and identifying their limitations.
