NVIDIA launches Cosmos 3 Edge, 4B world model for on-device robots

Cosmos 3 Edge is a 4B omni-model with a 2B Nemotron-based reasoner, pretrained on the same physical-world data as Cosmos 3 Nano and Super, and runs on-device on NVIDIA Jetson Thor. The tutorial covers post-training it to predict robot actions, serving policies on Jetson Thor, and evaluating in closed-loop simulation; the cosmos-framework repo and HuggingFace checkpoint are open.
