Train
By default, fine-tunes run automatically once the triplet budget for a domain is reached. Use this endpoint to force a run sooner: right after a major product change, a marketing push that shifts your user mix, or to validate that newly added outcomes flow through.

Example response

The call returns immediately. The actual fine-tune runs async, typically 15 to 60 minutes depending on triplet volume. The new head is deployed when training completes; subsequent /match requests automatically use it.
We notify the email on file when a run completes. Webhook callbacks land in a later release.
