# First message of a new chat no longer drops or shows out of order

> A new chat thread now replays from its first event when it subscribes, so the opening message is delivered and appears above later replies.

In a fresh chat thread, the first message could be missed by the live stream and then render below every later message. The session SSE stream now accepts `after_sequence`: `after_sequence=0` replays the session from its first event before going live, and the UI sends it when it holds no events yet. `since_id` still handles reconnects; passing both returns `400`.

The chat composer is also locked when no explicit or default model resolves, with the model menu left enabled to fix it.
