Message threads are now in public beta on the Messages API.
This is a dev post classified by AGK Intelligence as Backend & APIs (a launch), kept by the Dev Radar because it carries real work, not commentary.
Message threads are now in public beta on the Messages API. The API caches your conversation on the server between turns, so instead of resending the full conversation, you send only new messages and the previous message ID, and Claude starts responding sooner.
