Responses

responses.connect()

**** ``

Connect to a persistent Responses API WebSocket. Send response.create events and receive response stream events over the socket.

Example

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ.get("OPENAI_API_KEY"),  # This is the default and can be omitted
)
client.responses.connect()

Create a model response

responses.create(ResponseCreateParams**kwargs) -> Response

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

  • background: Optional[bool]

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

  • context_management: Optional[Iterable[ContextManagement]]

    Context management configuration for this request.

    • type: str

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

    • compact_threshold: Optional[int]

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

  • conversation: Optional[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.

    • str

      The unique ID of the conversation.

    • class ResponseConversationParam: …

      The conversation that this response belongs to.

      • id: str

        The unique ID of the conversation.

  • include: Optional[List[ResponseIncludable]]

    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.

  • service_tier: Optional[Literal["auto", "default", "flex", 2 more]]

    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.

    Options for streaming responses. Only set this when you set stream: true.

    • include_obfuscation: Optional[bool]

      When true, stream obfuscation will be enabled. Stream obfuscation adds random characters to an obfuscation field on streaming delta events to normalize payload sizes as a mitigation to certain side-channel attacks. These obfuscation fields are included by default, but add a small amount of overhead to the data stream. You can set include_obfuscation to false to optimize for bandwidth if you trust the network links between your application and the OpenAI API.

  • temperature: Optional[float]

    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: Optional[ResponseTextConfigParam]

    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

    • format: Optional[ResponseFormatTextConfig]

      An object specifying the format that the model must output.

      Configuring { "type": "json_schema" } enables Structured Outputs, which ensures the model will match your supplied JSON schema. Learn more in the Structured Outputs guide.

      The default format is { "type": "text" } with no additional options.

      Not recommended for gpt-4o and newer models:

      Setting to { "type": "json_object" } enables the older JSON mode, which ensures the message the model generates is valid JSON. Using json_schema is preferred for models that support it.

      • class ResponseFormatText: …

We recommend hashing their username or email address, in order to avoid sending us any identifying information. Learn more.

    • service_tier: Optional[Literal["auto", "default", "flex", 2 more]]

      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.

      • "auto"

      • "default"

      • "flex"

      • "scale"

      • format: Optional[ResponseFormatTextConfig]

        An object specifying the format that the model must output.

        Configuring { "type": "json_schema" } enables Structured Outputs, which ensures the model will match your supplied JSON schema. Learn more in the Structured Outputs guide.

        The default format is { "type": "text" } with no additional options.

        Not recommended for gpt-4o and newer models:

        Setting to { "type": "json_object" } enables the older JSON mode, which ensures the message the model generates is valid JSON. Using json_schema is preferred for models that support it.

    • truncation: Optional[Literal["auto", "disabled"]]

      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.

      • "auto"

Get a model response

responses.retrieve(strresponse_id, ResponseRetrieveParams**kwargs) -> Response

get /responses/{response_id}

Retrieves a model response with the given ID.

Parameters

  • response_id: str

  • include: Optional[List[ResponseIncludable]]

    Additional fields to include in the response. See the include parameter for Response creation above for more information.

    • "file_search_call.results"

    • "web_search_call.results"

    • "web_search_call.action.sources"

    • "message.input_image.image_url"

    • "computer_call_output.output.image_url"

    • "code_interpreter_call.outputs"

    • "reasoning.encrypted_content"

    • "message.output_text.logprobs"

  • include_obfuscation: Optional[bool]

    When true, stream obfuscation will be enabled. Stream obfuscation adds random characters to an obfuscation field on streaming delta events to normalize payload sizes as a mitigation to certain side-channel attacks. These obfuscation fields are included by default, but add a small amount of overhead to the data stream. You can set include_obfuscation to false to optimize for bandwidth if you trust the network links between your application and the OpenAI API.

  • starting_after: Optional[int]

    The sequence number of the event after which to start streaming.

  • stream: Optional[Literal[false]]

    If set to true, the model response data will be streamed to the client as it is generated using server-sent events. See the Streaming section below for more information.

    • false

Returns

  • class Response: …

    • id: str

      Unique identifier for this Response.

    • created_at: float

      Unix timestamp (in seconds) of when this Response was created.

    • error: Optional[ResponseError]

        concise is supported for computer-use-preview models and all reasoning models after gpt-5.

        • "auto"

        • "concise"

        • "detailed"

    • safety_identifier: Optional[str]

      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, with a maximum length of 64 characters. We recommend hashing their username or email address, in order to avoid sending us any identifying information. Learn more.

    • service_tier: Optional[Literal["auto", "default", "flex", 2 more]]

      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.

      • "auto"

      • "default"

      • "flex"

      • "scale"

      • "priority"

    • status: Optional[ResponseStatus]

      The status of the response generation. One of completed, failed, in_progress, cancelled, queued, or incomplete.

      • "completed"

      • "failed"

      • "in_progress"

      • "cancelled"

      • "queued"

      • "incomplete"

    • text: Optional[ResponseTextConfig]

      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

      • format: Optional[ResponseFormatTextConfig]

        An object specifying the format that the model must output.

        Configuring { "type": "json_schema" } enables Structured Outputs, which ensures the model will match your supplied JSON schema. Learn more in the Structured Outputs guide.

        The default format is { "type": "text" } with no additional options.

        Not recommended for gpt-4o and newer models:

        Setting to { "type": "json_object" } enables the older JSON mode, which ensures the message the model generates is valid JSON. Using json_schema is preferred for models that support it.

        • class ResponseFormatText: …

          Default response format. Used to generate text responses.

          • type: Literal["text"]

            The type of response format being defined. Always text.

            • "text"
        • class ResponseFormatTextJSONSchemaConfig: …

          JSON Schema response format. Used to generate structured JSON responses. Learn more about Structured Outputs.

          • name: str

            • "json_schema"
          • description: Optional[str]

            A description of what the response format is for, used by the model to determine how to respond in the format.

          • strict: Optional[bool]

            Whether to enable strict schema adherence when generating the output. If set to true, the model will always follow the exact schema defined in the schema field. Only a subset of JSON Schema is supported when strict is true. To learn more, read the Structured Outputs guide.

        • 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.

    • truncation: Optional[Literal["auto", "disabled"]]

      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.

      • "auto"

    • service_tier: Optional[Literal["auto", "default", "flex", 2 more]]

      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'.

                  Allows to set transparency for the background of the generated image(s). This parameter is only supported for GPT image models that support transparent backgrounds. Must be one of transparent, opaque, or auto (default value). When auto is used, the model will automatically determine the best background for the image.

                  gpt-image-2 and gpt-image-2-2026-04-21 do not support transparent backgrounds. Requests with background set to transparent will return an error for these models; use opaque or auto instead.

                  If transparent, the output format needs to support transparency, so it should be set to either png (default value) or webp.

        • service_tier: Optional[Literal["auto", "default", "flex", 2 more]]

          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.

We recommend hashing their username or email address, in order to avoid sending us any identifying information. Learn more.

        • service_tier: Optional[Literal["auto", "default", "flex", 2 more]]

          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.
