Properties

candidateCount

candidateCount?: number;

responseSchema

responseSchema?: ResponseSchema;

Optional. The schema that generated candidate text must follow. For more information, see https://cloud.google.com/vertex-ai/generative-ai/docs/multimodal/control-generated-output. If set, a compatible responseMimeType must also be set.
