NVIDIA'S COSMOS FAMILY TRAINS ON MASSIVE VIDEO CORPORA. A UNIVERSITY LAB JUST BEAT ONE OF ITS MODELS WITH A FRACTION OF THAT DATA. Orbis 2, University of Freiburg working with NATIX, outperformed Cosmos-v2.5 on generalization, scene understanding, and long-horizon stability specifically, not across every benchmark that exists. Independent trade coverage confirms the core numbers. Roughly half the parameters. Roughly a third of the data. Under 3,000 H100 GPU-hours. NATIX's crowdsourced driving footage supplied over 40% of the training mix, the largest single source. This is the second world model built on NATIX data, after a prior collaboration with Valeo AI.(CyrilXBT)
