Architecture and scope

The project links a reference implementation, released weights and a server/client integration path. Embodiment prompts distinguish datasets and control spaces rather than implying that robot interfaces are interchangeable.

Integration and evaluation

A LeRobot integration is available. The maintainers warn that converted Hugging Face-format weights can differ slightly in performance from the original format; preserve the format in an evaluation record.

Reported benchmark results

Context before scores. Results from different benchmarks are not directly comparable. A simulation result does not establish real-world reliability, safety or commercial availability.
No result meets our complete revision and methodology requirements for this record yet. Inspect the original benchmark documentation before comparing published scores.

What this evidence does not establish

  • Reference and converted checkpoints should not share scores without an explicit equivalence check.
  • Pricing and deployment service terms were not verified.

Relationships & deployments

Related reading is an editorial crosslink. Sourced connections describe relationships reported in the cited material. A link to a versioned profile does not establish compatibility with that version unless the connection note explicitly identifies it.

Record history & verified changes

A research review records when we checked a source. It does not mark a product launch or a new deployment.

Initial reviewed record. No subsequent field change has been recorded.
