Definition
The model field names the model that performs the evaluation. Examples use jev-latest, which is also the SDK default, but a pinned version such as jev-1.13.0 is accepted whether or not it appears in the models list.
The response echoes the versioned ID that actually answered, so logs can record which build produced each result even when a request used an alias.
