RDT-1B

Robotics Diffusion Transformer (RDT-1B): a 1B parameter diffusion-based VLA for bimanual manipulation. Developed by Tsinghua University. Competitive with pi0 and OpenVLA on real-world dexterous tasks.

Yes. RDT-1B is recorded as open-source / open-weights on the DEPLOY registry, meaning model weights or source code are publicly available.

RDT-1B is a research model, built on a Diffusion Transformer, 1B params architecture on the DEPLOY registry.

RDT-1B is at the research stage on the DEPLOY maturity ladder. Research stage means active development without commercial deployments on file.

No robot models on the DEPLOY registry are recorded as running RDT-1B. DEPLOY wires brain-to-model connections only when the wiring is verifiable from primary sources; absence may reflect pre-deployment or unverified manufacturer claims.
