Optional ReadonlydescriptionLonger description reported by the provider.
Optional ReadonlyfeaturedSet by a provider that knows better than the generic ranking which of its models should be offered in the model pickers without the user asking. GitHub Copilot serves several vendors, so "the five newest" would offer five models of whichever vendor names its models with the highest numbers; it therefore nominates one per vendor itself. Left unset by the other providers.
ReadonlyidProvider-native model id, without the <provider>/ prefix.
Optional ReadonlylabelHuman-readable name reported by the provider, e.g. Claude Opus 5.
Optional ReadonlyreleasedRelease date (ms since epoch) reported by the provider, used to order dated variants.
A model a provider reported from its list endpoint.
Only id is guaranteed: the endpoints differ widely in what they report about a model. Anthropic gives a display name and a release date, Google additionally a description, and OpenAI nothing but the id.
