Quick answerOnce a production AI agent regression is confirmed (not just detected, confirmed and diagnosed), the platform team needs a written commitment on how fast a fix ships: a target time-to-remediate by severity, clear authority for who can trigger an immediate rollback versus wait for a forward fix, and a defined escalation path if that clock is missed. This is a narrower question than a general internal platform SLA, which typically only commits to acknowledgment and detection targets, and it is a different question from who is staffed on-call to notice the regression in the first place.
Confirmed is the starting line, not detection
A lot of internal SLA language stops at detection and acknowledgment: how fast will someone notice, how fast will someone say "we're looking at it." What KPIs Belong in an Internal AI Platform Team SLA? covers that ground well, alongside change turnaround and cost ceilings, as part of a broader team-to-business-unit agreement. But acknowledgment is not resolution, and a company that only measures time-to-acknowledge can leave a confirmed, understood regression sitting unfixed for hours while technically staying "within SLA." The fix-time commitment covered here starts the clock at the moment the regression is confirmed and its cause is understood well enough to act on, and it ends when a real fix, not a workaround, is live.
Setting the target by severity, not a single number
A single fix-time target across every regression either sets an unrealistically fast bar for complex issues or an unacceptably slow one for severe issues. Tier it instead: a Sev1 regression (the agent giving materially wrong answers at volume, or failing entirely) should carry a tight remediate-or-rollback target, commonly under an hour for teams running mature CI/CD on their agent stack. A Sev3 (a narrow, low-traffic quality regression) can reasonably carry a next-business-day target. Publish the tiers, and be explicit that the clock is time-to-remediate-or-rollback, whichever comes first, not time-to-permanent-fix.
Rollback authority has to be pre-decided, not debated live
The fastest fix is often not a fix at all, it is a rollback to the last known-good agent version or prompt configuration. The single biggest reason teams miss fix-time targets is not technical difficulty, it is a live argument about whether rolling back is warranted while the regression is still active. Decide this in advance: name the role (not a specific person, since people rotate) with unilateral authority to trigger a rollback for a Sev1, with no approval chain required in the moment. Reserve the post-incident retrospective, covered in What Should Trigger a Company to Build a Dedicated AI Incident Response Runbook, for evaluating whether the rollback call was right, not for making the call itself.

Escalation when the clock is missed
Define what happens automatically when a fix-time target is about to be breached, before it happens rather than as an ad hoc reaction: an automatic page to a more senior engineer, a mandatory rollback trigger if a forward fix has not landed by a set checkpoint, and a required customer-facing status update if the target is missed on anything customer-visible, following the same communication discipline as What Should a Company Communicate to Customers After an AI Agent Has a Production Incident. Missing a fix-time target should trigger a defined next step automatically, not a scramble to figure one out.
Where staffing coverage fits, and where it does not
Staffing determines whether anyone is watching when a regression happens; the fix-time SLA determines what they are obligated to do once they are. Keep them as separate documents. A team can be fully staffed around the clock and still have no commitment on how fast a confirmed issue actually gets fixed, which is the gap this SLA closes.
FAQ
Does this replace the on-call staffing model? No, they answer different questions: staffing determines who is watching, and this SLA determines what they are committed to do, on what timeline, once a regression is confirmed.
What counts as "confirmed" versus just "reported"? Confirmed means the team has reproduced or otherwise verified the regression and identified enough about the cause to choose between rollback and forward fix; a report alone, without that verification, is still in the detection and triage phase.
Should the fix-time target include the time to write a postmortem? No, keep the fix-time clock scoped to remediation or rollback only, and treat the postmortem as a separate, slightly longer-timeline deliverable that follows once the immediate regression is resolved.
