Feedback loop

/'fee.dbak loop/The continuous cycle connecting production traces to eval datasets to system improvements and back to production. (noun)

Why it matters

The speed of your feedback loop determines how fast your AI product improves. The loop works like this: you observe production behavior, identify problems, turn those problems into dataset records, run experiments to validate fixes, and deploy the improvements back to production. If any step in that cycle is slow or manual, improvements stall. Teams that take weeks to go from a production bug to a measured fix will always fall behind teams that do it in hours. The most common bottleneck is the gap between production and evals. If your production traces live in one system and your eval datasets live in another, every iteration requires manual data export, reformatting, and re-upload. Tightening the loop means making it easy to go from a flagged trace directly to a new dataset record, run an experiment against it, and verify the fix, all within the same workflow. The tighter this cycle, the more iterations you get per week, and iteration count is the strongest predictor of product quality.

We tightened the feedback loop by turning flagged traces into new dataset records weekly.

Customer example

Retool built a feedback loop from production to product: they classify intent, monitor dashboards, and use Loop to analyze patterns in traces, then turn real queries into focused datasets and scorers, improving a front-of-house classifier from ~72% to ~95% accuracy. Read more
