Model Monitoring
The practice of continuously tracking AI model performance, data quality, and system health in production to detect degradation and trigger remediation.
In Depth
Model monitoring is the practice of continuously observing and evaluating the performance, behavior, and operational health of AI models deployed in production environments. Unlike traditional software monitoring that primarily tracks system metrics, model monitoring must also assess the quality and reliability of model predictions, which can degrade over time due to changes in data patterns, user behavior, or the underlying world the model represents.
Model monitoring encompasses several monitoring dimensions. Performance monitoring tracks prediction accuracy, latency, and throughput against defined service level objectives. Data monitoring detects changes in input data distributions (data drift) that may indicate the model is encountering unfamiliar patterns. Concept drift monitoring identifies when the relationship between inputs and correct outputs changes, rendering the model learned patterns obsolete. Fairness monitoring ensures model predictions remain equitable across demographic groups.
Effective monitoring systems combine automated detection with actionable alerting. Statistical tests like the Kolmogorov-Smirnov test, Population Stability Index (PSI), and Jensen-Shannon divergence quantify drift magnitude. Threshold-based alerts notify teams when metrics breach acceptable bounds. Dashboards provide visual overviews of model health across the organization portfolio. Integration with MLOps pipelines can trigger automated retraining when performance drops below defined thresholds.
Enterprise model monitoring is essential for maintaining trust in AI systems and meeting regulatory requirements. Financial services regulators expect ongoing model validation and performance reporting. Healthcare AI requires continuous monitoring of diagnostic accuracy. Any customer-facing AI must be monitored for bias, quality degradation, and safety issues. The monitoring infrastructure should scale with the number of deployed models and provide a unified view across the organization AI portfolio.
