Conversation Title

Set "title": {"enabled": true} to have the response carry a short title for the conversation, for example to show in a conversation list. The model writes the title together with the answer, so no extra request is needed.

Where the title appears in the response:

Protocol	Non-streaming	Streaming
Messages	Top-level title	delta.title of the message_delta event
Responses	Top-level title	response.title of the final event
Chat Completions	message.title	delta.title of the last chunk

event: message_delta
data: {"type":"message_delta","delta":{"stop_reason":"end_turn","stop_sequence":null,"title":"Beijing weather tomorrow"},"usage":{...}}

• After the answer ends, the response waits up to 5 seconds for the title before it finishes. Enable title only on the first request of a conversation, and stop enabling it once you have a title.
• A response may come without a title, for example after a refusal or an error. Fall back to something like the first characters of the user's message.
• The title is not billed.
