Version and date boundaries matter. The exact revision below defines each column. A deployment of an earlier revision is not evidence that a newer revision is in production. Missing fields remain unknown.

Embodiment

Hardware and control boundaries are part of the evaluation.

Compute

Confirm requirements for the intended workload.

Integrations

Verify exact versions, interfaces and support responsibilities.

Not publicly disclosedNot publicly disclosed

Choose based on your constraints.

These are evaluation paths, not a ranking. Verify the current terms and run a task-specific trial before committing.

Your team already has a data and robot interface

Inspect the observation and action formats, normalization and supported integration path for each exact release. Account for conversion and calibration work.

Your team needs a defensible experiment

Hold embodiment, data split and evaluation conditions constant. Treat published results as protocol-specific evidence rather than a global ordering of models.

Evidence gaps to resolve

  • Published fields describe the identified revision only; configuration and source dates may differ.
  • No matched independent operating trial is asserted by this comparison. Missing price, reliability and intervention figures remain unknown.
  • Benchmark results require the same protocol, inputs and revision context. Cross-benchmark totals are not calculated.
