ModelInfo models().retrieve(params = ModelRetrieveParams.none(), requestOptions = RequestOptions.none())
GET/v1/models/{model_id}

Obtenir un modèle spécifique.

La réponse de l'API Models peut être utilisée pour obtenir des informations sur un modèle spécifique ou pour résoudre un alias de modèle en identifiant de modèle.

Parameters
ModelRetrieveParams params
Optional<String> modelId⁠Path parameter

Model identifier or alias.

Optional<String> workspaceId⁠Header parameter

Optional header to select the Workspace for this request. The value is a Workspace ID (for example, wrkspc_011CZkZaBF1tNoB5wlCeusgy).

Only needed for credentials that can act on more than one Workspace. A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace.

Optional<List<AnthropicBeta>> betas⁠Header parameterDeprecated

Optional header to specify the beta version(s) you want to use.

Deprecated. This parameter will be removed from this method in a future release. To use beta features, call the beta models methods (`client.beta.models`) instead.
