What is AI model drift detection?

A monitoring framework that detects when model performance, latency, cost, safety, or behavior deviates from established baselines, triggering severity-appropriate remediation.

How often should we refresh drift baselines?

Monthly baseline refresh is recommended for production models; high-traffic systems may need weekly updates.

What drift signals should we monitor?

Core signals include accuracy degradation, latency spikes, cost anomalies, safety filter bypass, and behavioral pattern shifts.

How do we define drift thresholds?

Establish thresholds based on historical variance (e.g., > 5% accuracy drop, > 2x latency increase) with severity levels for response priority.

Who should own drift detection signals?

Assign signal owners by type: accuracy to model ops, latency to infrastructure, cost to FinOps, safety to security, behavior to product.
