# How to Reduce the Cost of AI Incidents in Production

Lower the number and cost of AI regressions that reach users by testing the behaviors that actually fail in production.

**Question:** How do I stop AI regressions from reaching production?

## Short answer

Fewer regressions escape only when the checks you run before release represent the behavior that fails in production. Build the suite from real failures and high-risk tasks, gate releases on the cases that matter most, and compare escaped incidents and their cost before and after. Evaluation cannot catch failures it has never seen, so keep feeding new production failures back into the suite.

## Key takeaways

- Coverage matters more than test count; checks must represent real production behavior.
- Price incidents with support time, engineering time, refunds, and customer impact, not just downtime.
- Every escaped incident should become a check so the same failure cannot ship twice.

## Signs this is the problem

- Users or support find AI problems before the team does.
- Pre-release tests pass while production complaints rise after the same change.
- Nobody can say what the last AI incident cost the business.

## Step-by-step approach

### 1. Price a typical incident

Add up engineering response time, support handling, refunds or credits, and any customer or compliance impact for recent AI incidents.

### 2. Map failures to coverage

For each recent incident, check whether any pre-release case would have caught it; the gaps show where the suite is not representative.

### 3. Build cases from production

Sample real traces, especially failures and high-risk tasks, and turn them into reviewed cases with clear expected behavior.

### 4. Gate on critical behavior

Block releases on failures in the critical cases rather than on an average score that can hide a serious regression.

### 5. Close the loop

When an incident still escapes, add it to the suite and record whether the gate would now catch it.

## What to measure

| Metric | What it measures | How to use it |
| --- | --- | --- |
| Escaped regressions per release | AI regressions first found after release, normalized by the number of releases. | Compare the rate before and after gating, weighted by severity. |
| Cost per incident | Engineering, support, refund, and customer-impact cost of a typical AI incident. | Multiply by the change in incident rate to estimate avoided cost. |
| Pre-release catch rate | Share of known regressions caught by the gate before release rather than by users after. | A low rate means the suite does not represent production behavior yet. |

## Common mistakes

- Claiming fewer incidents when the checks only cover easy, synthetic cases.
- Pricing incidents as downtime only and ignoring support load and lost trust.
- Treating a quiet month as proof the gate works without checking release volume.

## Practical checklist

- [ ] Price a typical incident: Add up engineering response time, support handling, refunds or credits, and any customer or compliance impact for recent AI incidents.
- [ ] Map failures to coverage: For each recent incident, check whether any pre-release case would have caught it; the gaps show where the suite is not representative.
- [ ] Build cases from production: Sample real traces, especially failures and high-risk tasks, and turn them into reviewed cases with clear expected behavior.
- [ ] Gate on critical behavior: Block releases on failures in the critical cases rather than on an average score that can hide a serious regression.
- [ ] Close the loop: When an incident still escapes, add it to the suite and record whether the gate would now catch it.

## Where EvalGate fits

EvalGate builds cases from real traces and failures, gates releases on the behaviors you mark as critical, and links each escaped incident back to the check that now covers it.

## Frequently asked questions

### What should I do first?

Add up engineering response time, support handling, refunds or credits, and any customer or compliance impact for recent AI incidents

### How should the result be measured?

AI regressions first found after release, normalized by the number of releases. Compare the rate before and after gating, weighted by severity.

### When is the change ready to ship?

Ship only after the protected cases pass, the primary metric clears its agreed boundary, and the team reviews the remaining failure modes instead of relying on one aggregate score.
