Notable capabilities (3)
- Human egocentric video pretraining: Pretrained on 20,854 hours of human egocentric video (EgoScale) across 20+ task categories, on top of robot data. source
- FIRST Scaling law for robot dexterity: NVIDIA reports the 'first-ever scaling law for robot dexterity': more human video predictably improves 22-DoF hand performance without mass teleoperation. source
- Reasoning VLA on a Cosmos backbone: 3B 'Action Cascade' model: Cosmos-Reason2-2B VLM plus 32-layer diffusion transformer; relative end-effector action space; runs on one 16 GB+ GPU including Jetson Thor/Orin and DGX Spark. source
The current open GR00T release; GR00T N2 (world action model) is due by end of 2026.

Timeline entry
- NVIDIA GTC 2026 robotics: GR00T N2 world action model previewed, Cosmos 3 and GR00T N1.7 announced ★★★
At GTC on 2026-03-16 NVIDIA previewed Isaac GR00T N2, a "world action model" based on DreamZero research that it says succeeds at new tasks in new environments over twice as often as leading VLAs (due by end of 2026), announced Cosmos 3 as a single model unifying world generation, reasoning and…
