Rollback
Reverting a **live AI deployment** to the last known-good model, prompt, or retrieval index when quality or error metrics breach thresholds.
When to use
Groundedness drops sharply, 5xx spikes, or a bad prompt/model swap hits production traffic.
When not to
On every minor latency blip — pair rollback with SLOs and baselines to avoid alert fatigue.
Example
Citation rate falls 35% day-over-day after a chunking change → auto-rollback retrieval config and page on-call.
