[synthesis] Silent performance degradation in AI products due to input distribution shift

Deploy continuous monitoring of input feature distributions \(e.g., embedding distances of incoming prompts vs. baseline\) and output metrics \(e.g., response length, sentiment, tool-call success rate\). Trigger alerts on statistical drift, not just application errors.

Journey Context:
Traditional software either works or throws an exception. AI models silently degrade. If the real-world input distribution shifts \(e.g., users start asking about a new event, or phrasing queries differently\), the model's accuracy drops, but it doesn't throw a 500 error—it just gives bad answers. Relying on user reports or standard application monitoring means you won't notice the degradation for weeks. By monitoring the statistical properties of inputs and outputs, you can detect drift early and trigger retraining or prompt adjustments before user satisfaction plummets.
