Enterprise AI & Agentic AI
What is AI drift monitoring and why does it matter?
AI drift monitoring tracks how a production AI system changes over time: model outputs, input distributions, retrieval quality, intent mix, cost per task and error rates. It matters because accuracy and cost degrade even when nothing is intentionally shipped — vendor model updates, new products, policy changes and seasonal traffic all move the system. Drift monitoring is what catches those changes before customers or regulators do.

Key takeaways
- Drift happens without a releaseVendor model updates, content changes and traffic mix shifts all affect outputs; scheduled evaluation runs detect that drift before customers report it.
- Cost drift is as important as quality driftToken, minute and platform costs are tracked per use case so routing and caching changes can be applied when unit economics move.
- Monitoring is the governance control that lastsDrift, refusal rates, escalation quality and cost are tracked continuously; governance without production telemetry is documentation only.
