Signal NVIDIA's Cosmos, launched 2025, was trained on 20 million hours of physical-world data

Summary

The report identifies NVIDIA's Cosmos platform as the most significant early deployment of world-model ideas. Launched in 2025, Cosmos was trained on 20 million hours of physical-world data. That data spans robotics, industrial settings and driving. According to the report, robots trained on Cosmos can generalize to physical situations they have never encountered. They do so by reasoning from an internal model of how things behave rather than drawing on a library of previously seen cases. The report presents this as one of the first platforms grounded in physical understanding to reach developers' hands.
