NVIDIA launches Cosmos 3 — first fully open "omnimodel" for physical AI

(June 1, GTC Taipei) — A mixture-of-transformers model combining vision reasoning, world generation, and action prediction; open weights on Hugging Face with Super/Nano/Edge variants. Why it matters for engineers: it's a genuinely open frontier model you can run and fine-tune, aimed at synthetic-data generation and robotics/AV policy work — cutting training/eval cycles from months to days.
