public struct LiveGenerationConfig : Sendable

Configuration options for live content generation.

  • Creates a new LiveGenerationConfig value.

    Declaration

    Swift

    public init(temperature: Float? = nil, topP: Float? = nil, topK: Int? = nil,
            candidateCount: Int? = nil, maxOutputTokens: Int? = nil,
            presencePenalty: Float? = nil, frequencyPenalty: Float? = nil,
            responseModalities: [ResponseModality]? = nil,
            speech: SpeechConfig? = nil,
            inputAudioTranscription: AudioTranscriptionConfig? = nil,
            outputAudioTranscription: AudioTranscriptionConfig? = nil)

    Parameters

    temperature

    Controls the randomness of the language model’s output. Higher values (for example, 1.0) make the text more random and creative, while lower values (for example, 0.1) make it more focused and deterministic.
    topP

    Controls diversity of generated text. Higher values (e.g., 0.9) produce more diverse text, while lower values (e.g., 0.5) make the output more focused.
    topK

    Limits the number of highest probability words the model considers when generating text. For example, a topK of 40 means only the 40 most likely words are considered for the next token. A higher value increases diversity, while a lower value makes the output more deterministic.
    candidateCount

    The number of response variations to return; defaults to 1 if not set. Support for multiple candidates depends on the model; see the Cloud documentation for more details.
    maxOutputTokens

    Maximum number of tokens that can be generated in the response. See the configure model parameters documentation for more details.
    presencePenalty

    Controls the likelihood of repeating the same words or phrases already generated in the text. Higher values increase the penalty of repetition, resulting in more diverse output.
    frequencyPenalty

    Controls the likelihood of repeating words or phrases, with the penalty increasing for each repetition. Higher values increase the penalty of repetition, resulting in more diverse output.
    responseModalities

    The data types (modalities) that may be returned in model responses.
    speech

    Controls the voice of the model, when streaming audio via ResponseModality.
    inputAudioTranscription

    Configures (and enables) input transcriptions when streaming to the model.
    outputAudioTranscription

    Configures (and enables) output transcriptions when streaming to the model.
