## Common questions

### What is RT-X / Open X-Embodiment?

Google DeepMind's Open X-Embodiment initiative: the seminal cross-embodiment robot learning dataset and models (RT-1-X, RT-2-X) trained across 22 robot morphologies. Demonstrated positive transfer across robot platforms. Apache 2.0 license.

### Who developed RT-X / Open X-Embodiment?

RT-X / Open X-Embodiment is credited to Google DeepMind on the DEPLOY registry. Each developer attribution is verified via primary sources.

### Is RT-X / Open X-Embodiment open source?

Yes. RT-X / Open X-Embodiment 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 RT-X / Open X-Embodiment?

RT-X / Open X-Embodiment is a research model, built on a RT-1-X (35M) and RT-2-X (VLA) trained on Open X-Embodiment dataset architecture on the DEPLOY registry.

### What is RT-X / Open X-Embodiment's maturity stage?

RT-X / Open X-Embodiment is at the research stage on the DEPLOY maturity ladder. Research stage means active development without commercial deployments on file.

### Which robots run on RT-X / Open X-Embodiment?

No robot models on the DEPLOY registry are recorded as running RT-X / Open X-Embodiment. DEPLOY wires brain-to-model connections only when the wiring is verifiable from primary sources; absence may reflect pre-deployment or unverified manufacturer claims.
