Shipping an AI feature behind a flag
Dana Whitfield ·
A model change is a product change, and it deserves the same rollout discipline. The difference is that the metric you care about is usually not in your analytics tool.
What we changed
Pick the metric before the rollout. "It seems better" is not a result.
Tag every trace with the flag variant so cost and latency split by arm automatically.
Run for a full week. Weekday and weekend traffic ask different questions.
The full walkthrough is in the documentation.
