Fiddler AI vs Duckie

About

Fiddler AI is a Palo Alto-based machine learning monitoring company that provides a platform for monitoring the performance, fairness, and explainability of ML models deployed in production — addressing the reality that model behavior degrades over time as the real-world data distributions the model was trained on shift away from what the model actually encounters in production. The Fiddler platform provides continuous monitoring of input data distribution, output prediction distribution, model accuracy (when ground truth labels are available), and feature drift across the model's full feature set, generating automated alerts when monitored metrics exceed defined thresholds that indicate potential model degradation.
