Generating content

The Gemini API supports content generation with images, audio, code, tools, and more. For details on each of these features, read on and check out the task-focused sample code, or read the comprehensive guides.

Method: models.generateContent

Generates a model response given an input GenerateContentRequest. Refer to the text generation guide for detailed usage information. Input capabilities differ between models, including tuned models. Refer to the model guide and tuning guide for details.

Endpoint

post https://generativelanguage.googleapis.com/v1beta/{model=models/*}:generateContent

Path parameters

model string

Required. The name of the Model to use for generating the completion.

Format: name=models/{model}. It takes the form models/{model}.

Request body

The request body contains data with the following structure:

Fields
contents[] object (Content)

Required. The content of the current conversation with the model.

For single-turn queries, this is a single instance. For multi-turn queries like chat, this is a repeated field that contains the conversation history and the latest request.

tools[] object (Tool)

Optional. A list of Tools the Model may use to generate the next response.

A Tool is a piece of code that enables the system to interact with external systems to perform an action, or set of actions, outside of knowledge and scope of the Model. Supported Tools are Function and codeExecution. Refer to the Function calling and the Code execution guides to learn more.

toolConfig object (ToolConfig)

Optional. Tool configuration for any Tool specified in the request. Refer to the Function calling guide for a usage example.

safetySettings[] object (SafetySetting)

Optional. A list of unique SafetySetting instances for blocking unsafe content.

This will be enforced on the GenerateContentRequest.contents and GenerateContentResponse.candidates. There should not be more than one setting for each SafetyCategory type. The API will block any contents and responses that fail to meet the thresholds set by these settings. This list overrides the default settings for each SafetyCategory specified in the safetySettings. If there is no SafetySetting for a given SafetyCategory provided in the list, the API will use the default safety setting for that category. Harm categories HARM_CATEGORY_HATE_SPEECH, HARM_CATEGORY_SEXUALLY_EXPLICIT, HARM_CATEGORY_DANGEROUS_CONTENT, HARM_CATEGORY_HARASSMENT are supported. Refer to the guide for detailed information on available safety settings. Also refer to the Safety guidance to learn how to incorporate safety considerations in your AI applications.

systemInstruction object (Content)

Optional. Developer set system instruction(s). Currently, text only.

generationConfig object (GenerationConfig)

Optional. Configuration options for model generation and outputs.

cachedContent string

Optional. The name of the content cached to use as context to serve the prediction. Format: cachedContents/{cachedContent}

Response body

If successful, the response body contains an instance of GenerateContentResponse.

Method: models.streamGenerateContent

Generates a streamed response from the model given an input GenerateContentRequest.

Endpoint

post https://generativelanguage.googleapis.com/v1beta/{model=models/*}:streamGenerateContent

Path parameters

model string

Required. The name of the Model to use for generating the completion.

Format: name=models/{model}. It takes the form models/{model}.

Request body

The request body contains data with the following structure:

Fields
contents[] object (Content)

Required. The content of the current conversation with the model.

For single-turn queries, this is a single instance. For multi-turn queries like chat, this is a repeated field that contains the conversation history and the latest request.

tools[] object (Tool)

Optional. A list of Tools the Model may use to generate the next response.

A Tool is a piece of code that enables the system to interact with external systems to perform an action, or set of actions, outside of knowledge and scope of the Model. Supported Tools are Function and codeExecution. Refer to the Function calling and the Code execution guides to learn more.

toolConfig object (ToolConfig)

Optional. Tool configuration for any Tool specified in the request. Refer to the Function calling guide for a usage example.

safetySettings[] object (SafetySetting)

Optional. A list of unique SafetySetting instances for blocking unsafe content.

This will be enforced on the GenerateContentRequest.contents and GenerateContentResponse.candidates. There should not be more than one setting for each SafetyCategory type. The API will block any contents and responses that fail to meet the thresholds set by these settings. This list overrides the default settings for each SafetyCategory specified in the safetySettings. If there is no SafetySetting for a given SafetyCategory provided in the list, the API will use the default safety setting for that category. Harm categories HARM_CATEGORY_HATE_SPEECH, HARM_CATEGORY_SEXUALLY_EXPLICIT, HARM_CATEGORY_DANGEROUS_CONTENT, HARM_CATEGORY_HARASSMENT are supported. Refer to the guide for detailed information on available safety settings. Also refer to the Safety guidance to learn how to incorporate safety considerations in your AI applications.

systemInstruction object (Content)

Optional. Developer set system instruction(s). Currently, text only.

generationConfig object (GenerationConfig)

Optional. Configuration options for model generation and outputs.

cachedContent string

Optional. The name of the content cached to use as context to serve the prediction. Format: cachedContents/{cachedContent}

responseMimeType string

Optional. MIME type of the generated candidate text. Supported MIME types are: text/plain: (default) Text output. application/json: JSON response in the response candidates. text/x.enum: ENUM as a string response in the response candidates. Refer to the docs for a list of all supported text MIME types.

responseSchema object (Schema)

Optional. Output schema of the generated candidate text. Schemas must be a subset of the OpenAPI schema and can be objects, primitives or arrays.

If set, a compatible responseMimeType must also be set. Compatible MIME types: application/json: Schema for JSON response. Refer to the JSON text generation guide for more details.

candidateCount integer

Optional. Number of generated responses to return.

Currently, this value can only be set to 1. If unset, this will default to 1.

maxOutputTokens integer

Optional. The maximum number of tokens to include in a response candidate.

Note: The default value varies by model, see the Model.output_token_limit attribute of the Model returned from the getModel function.

temperature number

Optional. Controls the randomness of the output.

Note: The default value varies by model, see the Model.temperature attribute of the Model returned from the getModel function.

Values can range from [0.0, 2.0].

topP number

Optional. The maximum cumulative probability of tokens to consider when sampling.

The model uses combined Top-k and Top-p (nucleus) sampling.

Tokens are sorted based on their assigned probabilities so that only the most likely tokens are considered. Top-k sampling directly limits the maximum number of tokens to consider, while Nucleus sampling limits the number of tokens based on the cumulative probability.

Note: The default value varies by Model and is specified by theModel.top_p attribute returned from the getModel function. An empty topK attribute indicates that the model doesn't apply top-k sampling and doesn't allow setting topK on requests.

topK integer

Optional. The maximum number of tokens to consider when sampling.

Gemini models use Top-p (nucleus) sampling or a combination of Top-k and nucleus sampling. Top-k sampling considers the set of topK most probable tokens. Models running with nucleus sampling don't allow topK setting.

Note: The default value varies by Model and is specified by theModel.top_p attribute returned from the getModel function. An empty topK attribute indicates that the model doesn't apply top-k sampling and doesn't allow setting topK on requests.

presencePenalty number

Optional. Presence penalty applied to the next token's logprobs if the token has already been seen in the response.

This penalty is binary on/off and not dependant on the number of times the token is used (after the first). Use frequencyPenalty for a penalty that increases with each use.

A positive penalty will discourage the use of tokens that have already been used in the response, increasing the vocabulary.

A negative penalty will encourage the use of tokens that have already been used in the response, decreasing the vocabulary.

frequencyPenalty number

Optional. Frequency penalty applied to the next token's logprobs, multiplied by the number of times each token has been seen in the respponse so far.

A positive penalty will discourage the use of tokens that have already been used, proportional to the number of times the token has been used: The more a token is used, the more dificult it is for the model to use that token again increasing the vocabulary of responses.

Caution: A negative penalty will encourage the model to reuse tokens proportional to the number of times the token has been used. Small negative values will reduce the vocabulary of a response. Larger negative values will cause the model to start repeating a common token until it hits the maxOutputTokens limit: "...the the the the the...".

responseLogprobs boolean

Optional. If true, export the logprobs results in response.

logprobs integer

Optional. Only valid if responseLogprobs=True. This sets the number of top logprobs to return at each decoding step in the Candidate.logprobs_result.

{
  "stopSequences": [
    string
  ],
