| `phase`   | [OptionalNullable\[components.OutputMessageItemPhaseUnion\]](../components/outputmessageitemphaseunion.md)          | :heavy\_minus\_sign: | The phase of an assistant message. Use `commentary` for an intermediate assistant message and `final_answer` for the final assistant message. For follow-up requests with models like `gpt-5.3-codex` and later, preserve and resend phase on all assistant messages. Omitting it can degrade performance. Not used for user messages. |
