The cited official release is labelled early access; this record does not imply a later general-availability date.
The profile describes this checkpoint, not every release carrying the family name. Developer documentation is not independent reproduction.

NINE DIMENSIONS / NO OPENNESS SCORE
What is actually available?
Each component has its own evidence. “Not established” means this source review did not verify availability; it is not a claim that nothing exists.

What to explore.
- Humanoid manipulation
- Cross-embodiment fine-tuning
- Open robotics tooling
WHAT THE RECORD DOES NOT ESTABLISH
Keep the limits.
- Robot results depend on hardware, calibration, and safety controls
- Real-world operation needs physical safeguards
The original GR00T N1 paper provides research evaluation; N1.7 deployment claims remain primarily NVIDIA-reported.
CONNECTED EVIDENCE
A release becomes a starting point.
- A shared starting point for humanoid skills
Isaac GR00T N1.7 is a downloadable vision-language-action model intended as a base for developing humanoid robot skills.
The weights use the NVIDIA Open Model License, which is distinct from an OSI-approved open-source license. Public artifacts do not establish site-specific reliability or physical safety.
Thematic or family connections, not proof that an older application uses the selected checkpoint.
