    Declaration

    Swift

    public func generativeModel(modelName: String,
                            generationConfig: GenerationConfig? = nil,
                            safetySettings: [SafetySetting]? = nil,
                            tools: [Tool]? = nil,
                            toolConfig: ToolConfig? = nil,
                            systemInstruction: ModelContent? = nil,
                            requestOptions: RequestOptions = RequestOptions())
  -> GenerativeModel

    Parameters

    modelName

    The name of the model to use, for example "gemini-1.5-flash"; see available model names for a list of supported model names.
    generationConfig

    The content generation parameters your model should use.
    safetySettings

    A value describing what types of harmful content your model should allow.
    tools

    A list of Tool objects that the model may use to generate the next response.
    toolConfig

    Configuration parameters for sending requests to the backend.

  • [Public Preview] Initializes an ImagenModel with the given parameters.

    Warning

    For Vertex AI in Firebase, image generation using Imagen 3 models is in Public Preview, which means that the feature is not subject to any SLA or deprecation policy and could change in backwards-incompatible ways.

    Important: Only Imagen 3 models (named imagen-3.0-*) are supported.

    Declaration

    Swift

    public func imagenModel(modelName: String, generationConfig: ImagenGenerationConfig? = nil,
                        safetySettings: ImagenSafetySettings? = nil,
                        requestOptions: RequestOptions = RequestOptions()) -> ImagenModel

    Parameters

    modelName

    The name of the Imagen 3 model to use, for example "imagen-3.0-generate-002"; see model versions for a list of supported Imagen 3 models.
    generationConfig
