OpenAI Responses API streaming events response.output_text.done response.function_call_arguments.done response.refusal.done response.reasoning_summary_text.done

💡 Result:

In the OpenAI Realtime API, streaming "done" events represent the finalization of specific content parts or components within a model response [1][2]. These events are emitted by the server to confirm that a particular stream—such as text, function call arguments, or reasoning summaries—has completed [1][3][4][5][6]. They are also emitted if the response is interrupted, incomplete, or cancelled [3][4]. Key "done" events include: response.output_text.done Emitted when the generation of a text content part is complete [4]. It contains the finalized text, the item and response IDs, and indices [7][4]. response.function_call_arguments.done Emitted when the generation of function call arguments is complete [3]. It includes the final JSON-formatted arguments, the function name, and the associated call ID [3]. response.refusal.done Emitted when the model's refusal text is finalized [5][8]. It provides the complete refusal content [5][9]. response.reasoning_summary_text.done Emitted when the reasoning summary text for a model response is completed [6][10]. It includes the finalized summary text and sequence information [10][11][12]. These events complement the delta events (e.g., response.output_text.delta) used for real-time streaming updates [1][13]. While delta events allow you to render partial content, the corresponding "done" events provide the complete, finalized data necessary for final processing or state synchronization [1][3][4]. [14][1][3][4][5][6][10]

Mark finalized Responses events as billable output.

OaiResponsesStreamHandler ignores response.output_text.done, response.function_call_arguments.done, response.refusal.done, and response.reasoning_summary_text.done, although ResponsesStreamResponse exposes their finalized payloads. If response.completed then lacks usable usage and output, the fallback is skipped and calculateTextQuotaSummary sets the quota to zero. Mark non-empty finalized payloads as billable, use finalized text for token estimation, and add done-only regression tests.

In `@relay/channel/openai/relay_responses.go` around lines 129 - 130, Update
OaiResponsesStreamHandler to handle response.output_text.done,
response.function_call_arguments.done, response.refusal.done, and
response.reasoning_summary_text.done; mark non-empty finalized payloads as
billable output and feed their finalized text into token estimation when
response.completed lacks usable usage or output. Preserve existing delta
handling and add regression coverage for streams containing only done events.
