Show the answer as it comes in, like someone typing, instead of making me wait for the whole thing.

How events form a complete response

Pieces arrive: The server sends text or status events; one piece may not be a complete word.

The interface appends them: The product adds each text piece in order to the existing content.

Generation continues: Early content reduces perceived waiting, but total time still depends on the rest.

You can say this to an AI Agent

Use the real response stream to update one message incrementally and distinguish connecting, generating, complete, interrupted, and retry states. First content is not completion; preserve partial output on interruption and allow stop.
