Parameters

Name	Description
`background`	Whether to run the model response in the href="https://platform.openai.com/docs/guides/background">background.
`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.
`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. code_interpreter_call.outputs: Includes the outputs of python code execution in code interpreter tool call items. computer_call_output.output.image_url: Include image urls from the computer call output. file_search_call.results: Include the search results of the file search tool call. message.input_image.image_url: Include image urls from the input message. message.output_text.logprobs: Include logprobs with assistant messages. reasoning.encrypted_content: Includes an encrypted version of reasoning tokens in reasoning item outputs. This enables reasoning items to be used in multi-turn conversations when using the Responses API statelessly (like when the store parameter is set to false, or when an organization is enrolled in the zero data retention program).
`input`	Text, image, or file inputs to the model, used to generate a response. Learn more: - Text inputs and outputs - href="https://platform.openai .com/docs/guides/images-vision?api-mode=responses">Image inputs - File inputs - Conversation state - Function calling
`instructions`	When using along with previous_response_id, the instructions from a previous response will not be carried over to the next response. This makes it simple to swap out system (or developer) messages in new responses.
`maxOutputTokens`	An upper bound for the number of tokens that can be generated for a response, including visible output tokens and href="https://platform.openai.com/docs/guides/reasoning">reasoning tokens.
`maxToolCalls`	The maximum number of total calls to built-in tools that can be processed in a response. This maximum number applies across all built-in tool calls, not per individual tool. Any further attempts to call a tool by the model will be ignored.
`metadata`	Set of 16 key-value pairs that can be attached to an object. This can be useful for storing additional information about the object in a structured format, and querying for objects via API or the dashboard. Keys are strings with a maximum length of 64 characters. Values are strings with a maximum length of 512 characters.
`model`	Model ID used to generate the response, like gpt-4o or o3. OpenAI offers a wide range of models with different capabilities, performance characteristics, and price points. Refer to the model guide to browse and compare available models.
`parallelToolCalls`	Whether to allow the model to run tool calls in parallel.
`prompt`	Reference to a prompt template and its variables. Learn more.
`promptCacheKey`	Used by OpenAI to cache responses for similar requests to optimize your cache hit rates. Replaces the user field. href="https://platform.openai.com/docs/guides/prompt-caching">Learn more.
`promptCacheRetention`	The retention policy for the prompt cache. Set to 24h to enable extended prompt caching, which keeps cached prefixes active for longer, up to a maximum of 24 hours.
`reasoning`	Configuration options for reasoning models. Learn more.
`safetyIdentifier`	A stable identifier used to help detect users of your application that may be violating OpenAI's usage policies. The IDs should be a string that uniquely identifies each user. We recommend hashing their username or email address, in order to avoid sending us any identifying information. Learn more
`serviceTier`	Specifies the processing type used for serving the request. 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.
`store`	Whether to store the generated model response for later retrieval via API.
`stream`	If set to true, the model response data will be streamed to the client as it is generated using server-sent events. See the href="https://platform.openai.com/docs/api-reference/responses-streaming">Streaming section for more information.
`streamOptions`	Options for streaming responses. Only set this when you set stream: true.
`temperature`	What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or top_p but not both.
`text`	Configuration options for a text response from the model. Can be plain text or structured JSON data. Learn more: - Text inputs and outputs - Structured Outputs
`toolChoice`	How the model should select which tool (or tools) to use when generating a response. See the tools parameter to see how to specify which tools the model can call.
`tools`	An array of tools the model may call while generating a response. You can specify which tool to use by setting the tool_choice parameter. We support the following categories of tools: Built-in tools: Tools that are provided by OpenAI that extend the model's capabilities, like href="https://platform.openai.com/docs/guides/tools-web-search?api-mode=responses">web search or file search. Learn more about href="https://platform.openai.com/docs/guides/tools">built-in tools. MCP Tools: Integrations with third-party systems via custom MCP servers or predefined connectors such as Google Drive and SharePoint. Learn more about href="https://platform.openai.com/docs/guides/tools-connectors-mcp">MCP Tools. Function calls (custom tools): Functions that are defined by you, enabling the model to call your own code with strongly typed arguments and outputs. Learn more about href="https://platform.openai.com/docs/guides/function-calling">function calling. You can also use custom tools to call your own code.
`topLogprobs`	An integer between 0 and 20 specifying the number of most likely tokens to return at each token position, each with an associated log probability.
`topP`	An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature but not both.
`truncation`	The truncation strategy to use for the model response. auto: If the input to this Response exceeds the model's context window size, the model will truncate the response to fit the context window by dropping items from the beginning of the conversation. disabled (default): If the input size will exceed the context window size for a model, the request will fail with a 400 error.
`openRouterCustomPayload`	custom payload designed for OpenRouter Responses.
