Responses

Create a model response

Response responses().create(ResponseCreateParamsparams = ResponseCreateParams.none(), RequestOptionsrequestOptions = RequestOptions.none())

post /responses

Creates a model response. Provide text or image inputs to generate text or JSON outputs. Have the model call your own custom code or use built-in tools like web search or file search to use your own data as input for the model's response.

Parameters

• ResponseCreateParams params

  • Optional<Boolean> background

    Whether to run the model response in the background. Learn more.

  • Optional<List<ContextManagement>> contextManagement

    Context management configuration for this request.

    • String type

      The context management entry type. Currently only 'compaction' is supported.

    • Optional<Long> compactThreshold

      Token threshold at which compaction should be triggered for this entry.

  • Optional<Conversation> conversation

    The conversation that this response belongs to. Items from this conversation are prepended to input_items for this response request. Input items and output items from this response are automatically added to this conversation after this response completes.

    • String

    • class ResponseConversationParam:

      The conversation that this response belongs to.

      • String id

        The unique ID of the conversation.

  • Optional<List<ResponseIncludable>> include

    Specify additional output data to include in the model response. Currently supported values are:

    • web_search_call.action.sources: Include the sources of the web search tool call.

    • If set to 'auto', then the request will be processed with the service tier configured in the Project settings. Unless otherwise configured, the Project will use 'default'.
    • If set to 'default', then the request will be processed with the standard pricing and performance for the selected model.
    • If set to 'flex' or 'priority', then the request will be processed with the corresponding service tier.
    • When not set, the default behavior is 'auto'.

    When the service_tier parameter is set, the response body will include the service_tier value based on the processing mode actually used to serve the request. This response value may be different from the value set in the parameter.

      • class ResponseFormatJsonObject:

        JSON object response format. An older method of generating JSON responses. Using json_schema is recommended for models that support it. Note that the model will not generate JSON without a system or user message instructing it to do so.
