Get a model response

Response responses().retrieve(ResponseRetrieveParamsparams = ResponseRetrieveParams.none(), RequestOptionsrequestOptions = RequestOptions.none())
GET/responses/{response_id}

Retrieves a model response with the given ID.

ParametersExpand Collapse
ResponseRetrieveParams params
Optional<String> responseId
Optional<List<ResponseIncludable>> include

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

FILE_SEARCH_CALL_RESULTS("file_search_call.results")
WEB_SEARCH_CALL_RESULTS("web_search_call.results")
WEB_SEARCH_CALL_ACTION_SOURCES("web_search_call.action.sources")
MESSAGE_INPUT_IMAGE_IMAGE_URL("message.input_image.image_url")

Optional<Boolean> includeObfuscation

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.

Optional<Long> startingAfter
