發生什麼事

Using the Messages API for multi-turn chats used to require developers to resend the full conversation on every turn. @ClaudeDevs says message threads have entered public beta; the API keeps the conversation on the server, so a developer can provide the previous message's ID along with only the new messages. Anthropic says Claude can start answering sooner, too (🗣 self-reported).
