What it does

Capabilities carry their support status; tasks are labels, because seven descriptions would bury the section.

Capabilities (1)

Structured Output
Intrinsic support for constrained/structured machine-readable output.

Tasks (2)

Physical Scene ReasoningRobot Action Generation

Inputs & Outputs

Each modality is paired with the representation it is carried in, so a non-token model reads the same way a text one does.

Accepts

  • ImageRobot Camera Image
  • TextPlain Text
  • VectorRobot Proprioception

Produces

  • ActionRobot Action

Full pricing for a single offering is one step further in, from this model’s pricing page, because it is addressed by offering and this page carries the model. The calculator is disabled because it is not built.

Rates are not comparable across offerings unless meter, unit and conditions match.

Derived chronology

Model Journey

Assembled from this model’s own lifecycle records, its snapshots, its providers’ offering and pricing history, and recorded succession. It is a view over those records, not a second source of truth, and undated lineage is deliberately not on it.

The first control expands this section in place, without filters or navigation. The second opens the standalone journey, which adds filtering on three axes, year grouping, per-event provenance and a shareable address.

Every date is the source record’s own effective date — a model lifecycle date, a snapshot release, an offering’s effective date, a pricing version’s effective-from. None of them is a load or capture timestamp.
