Brain
NVIDIA's open humanoid foundation model and the first of its kind to be released openly. A dual-system VLA: System 2 uses NVIDIA-Eagle plus SmolLM-1.7B as the VLM at roughly 10 Hz; System 1 is a diffusion transformer producing real-time motor actions. Jointly trained end-to-end on real-robot trajectories, human videos, and synthetic data. Part of the broader Isaac GR00T platform that includes Isaac Lab, Omniverse, and Cosmos.

Architecture
Dual-system VLA. System 2: VLM (NVIDIA-Eagle + SmolLM-1.7B) at roughly 10 Hz. System 1: diffusion transformer producing real-time motor actions. Jointly trained end-to-end on real-robot trajectories, human videos, and synthetic data. Runs on Jetson AGX Thor at the edge.
Key facts
- DEPLOY maturity rationale
- Development platform with commercial integrations; not at-scale production despite source 'PRODUCTION' label. Re-derived as research-to-commercial; recorded here as research.
- Cross-embodiment
- Single-arm to bimanual humanoid; broad developer community via NVIDIA Isaac
- Integrations
- Integrated into NEURA robots (NEURA Cognitive Stack builds atop GR00T); broad developer use
- Released
- GTC announcement March 18, 2025; arXiv 2503.14734
- Hosted by
- GR00T N1.5 integrated into Hugging Face LeRobot
- Powered-models flagged (not in registry yet)
- NEURA 4NE-1, MiPA; broader cross-embodiment targets
