NVIDIA Cosmos 3 Edge is a 4-billion-parameter open world model that helps robots and vision AI agents understand their surroundings, reason in real time, and generate robot actions on edge devices. It is now available on Hugging Face. The model delivers memory-efficient, high-throughput inference across NVIDIA edge computers. It connects understanding, prediction, simulation, and action through a shared world representation. The model can be used as a reasoner or an action generator.
