# GR00T 2: robot foundation model

[NVIDIA](/companies/nvidia.md)’s open world action model for robot manipulation, built on NVIDIA Cosmos. It predicts future video and robot actions together and runs on parallel grippers, dexterous hands and humanoids. A smaller [GR00T](/brains/gr00t-n1.md) 2 Turbo variant runs on the [Unitree G1](/companies/unitree-robotics.md) humanoid’s own Jetson Thor.

- **Slug:** gr00t-2

## Common questions

### What is GR00T 2?

[NVIDIA](/companies/nvidia.md)’s open world action model for robot manipulation, built on NVIDIA Cosmos. It predicts future video and robot actions together and runs on parallel grippers, dexterous hands and humanoids. A smaller [GR00T](/brains/gr00t-n1.md) 2 Turbo variant runs on the [Unitree G1](/companies/unitree-robotics.md) humanoid’s own Jetson Thor.

### Who developed GR00T 2?

[GR00T](/brains/gr00t-n1.md) 2 is credited to [NVIDIA](/companies/nvidia.md) on the DEPLOY registry. Each developer attribution is verified via primary sources.

### Is GR00T 2 open source?

Yes. [GR00T](/brains/gr00t-n1.md) 2 is recorded as open-source / open-weights on the DEPLOY registry, meaning model weights or source code are publicly available.

### What type of AI is GR00T 2?

[GR00T](/brains/gr00t-n1.md) 2 is a foundation model on the DEPLOY registry.

### What is GR00T 2's maturity stage?

[GR00T](/brains/gr00t-n1.md) 2 is at the pilot stage on the DEPLOY maturity ladder. Pilot stage means at least one named-customer trial deployment is verified.

### Which robots run on GR00T 2?

No robot models on the DEPLOY registry are recorded as running [GR00T](/brains/gr00t-n1.md) 2. DEPLOY wires brain-to-model connections only when the wiring is verifiable from primary sources; absence may reflect pre-deployment or unverified manufacturer claims.
