# Send Message Stream

`POST /api/v1/chat/threads/{thread_id}/messages/stream`

Persist-first: save the user message + a streaming assistant placeholder, kick off a
detached generator, and return the ids. The client then attaches to the events endpoint
to stream the answer. Generation is decoupled from this request, so a refresh resumes it.
