    GenerationConfig

    Configuration for content generation.

    This message contains all the parameters that control how the model generates content. It allows you to influence the randomness, length, and structure of the output.

    Fields
    stopSequences[] string

    Optional. A list of character sequences that will stop the model from generating further tokens. If a stop sequence is generated, the output will end at that point. This is useful for controlling the length and structure of the output. For example, you can use ["\n", "###"] to stop generation at a new line or a specific marker.

    responseMimeType string

    Optional. The IANA standard MIME type of the response. The model will generate output that conforms to this MIME type. Supported values include 'text/plain' (default) and 'application/json'. The model needs to be prompted to output the appropriate response type, otherwise the behavior is undefined.

    responseModalities[] enum ( Modality )

    Optional. The modalities of the response. The model will generate a response that includes all the specified modalities. For example, if this is set to [TEXT, IMAGE] , the response will include both text and an image.

    thinkingConfig object ( ThinkingConfig )

    Optional. Configuration for thinking features. An error will be returned if this field is set for models that don't support thinking.

    temperature number

    Optional. Controls the randomness of the output. A higher temperature results in more creative and diverse responses, while a lower temperature makes the output more predictable and focused. The valid range is (0.0, 2.0].

    topP number

    Optional. Specifies the nucleus sampling threshold. The model considers only the smallest set of tokens whose cumulative probability is at least topP . This helps generate more diverse and less repetitive responses. For example, a topP of 0.9 means the model considers tokens until the cumulative probability of the tokens to select from reaches 0.9. It's recommended to adjust either temperature or topP , but not both.

    topK number

    Optional. Specifies the top-k sampling threshold. The model considers only the top k most probable tokens for the next token. This can be useful for generating more coherent and less random text. For example, a topK of 40 means the model will choose the next word from the 40 most likely words.

    candidateCount integer

    Optional. The number of candidate responses to generate.

    A higher candidateCount can provide more options to choose from, but it also consumes more resources. This can be useful for generating a variety of responses and selecting the best one.

    maxOutputTokens integer

    Optional. The maximum number of tokens to generate in the response.

    A token is approximately four characters. The default value varies by model. This parameter can be used to control the length of the generated text and prevent overly long responses.

    responseLogprobs boolean

    Optional. If set to true, the log probabilities of the output tokens are returned.

    log probabilities are the logarithm of the probability of a token appearing in the output. A higher log probability means the token is more likely to be generated. This can be useful for analyzing the model's confidence in its own output and for debugging.

    logprobs integer

    Optional. The number of top log probabilities to return for each token.

    This can be used to see which other tokens were considered likely candidates for a given position. A higher value will return more options, but it will also increase the size of the response.

    presencePenalty number

    Optional. Penalizes tokens that have already appeared in the generated text. A positive value encourages the model to generate more diverse and less repetitive text. Valid values can range from [-2.0, 2.0].

    frequencyPenalty number

    Optional. Penalizes tokens based on their frequency in the generated text. A positive value helps to reduce the repetition of words and phrases. Valid values can range from [-2.0, 2.0].

    seed integer

    Optional. A seed for the random number generator.

    By setting a seed, you can make the model's output mostly deterministic. For a given prompt and parameters (like temperature, topP, etc.), the model will produce the same response every time. However, it's not a guaranteed absolute deterministic behavior. This is different from parameters like temperature , which control the level of randomness. seed ensures that the "random" choices the model makes are the same on every run, making it essential for testing and ensuring reproducible results.

    responseSchema object ( Schema )

    Optional. Lets you to specify a schema for the model's response, ensuring that the output conforms to a particular structure. This is useful for generating structured data such as JSON. The schema is a subset of the OpenAPI 3.0 schema object object.

    When this field is set, you must also set the responseMimeType to application/json .

    responseJsonSchema value ( Value format)

    Optional. When this field is set, responseSchema must be omitted and responseMimeType must be set to application/json .

    routingConfig object ( RoutingConfig )

    Optional. Routing configuration.

    audioTimestamp boolean

    Optional. If enabled, audio timestamps will be included in the request to the model. This can be useful for synchronizing audio with other modalities in the response.

    mediaResolution enum ( MediaResolution )

    Optional. The token resolution at which input media content is sampled. This is used to control the trade-off between the quality of the response and the number of tokens used to represent the media. A higher resolution allows the model to perceive more detail, which can lead to a more nuanced response, but it will also use more tokens. This does not affect the image dimensions sent to the model.

    speechConfig object ( SpeechConfig )

    Optional. The speech generation config.

    enableAffectiveDialog boolean

    Optional. If enabled, the model will detect emotions and adapt its responses accordingly. For example, if the model detects that the user is frustrated, it may provide a more empathetic response.

    imageConfig object ( ImageConfig )

    Optional. Config for image generation features.
