[synthesis] AI product silently degrades in production with no alerts while error rates stay flat

Implement semantic monitoring alongside traditional observability: \(1\) run a golden eval set against production models on a cron \(every 1-6 hours\), tracking score drift not just pass/fail, \(2\) monitor output distribution statistics \(response length, refusal rate, citation density, sentiment\) as canary metrics, \(3\) track user correction signals \(regenerate rate, edit distance from AI output to final text, thumbs-down rate\) as a real-time quality proxy. Alert on distribution shifts, not just errors.

Journey Context:
Traditional software fails loudly—exceptions, crashes, 5xx errors. AI fails silently by generating plausible but wrong answers with high confidence. Standard monitoring \(error rate, latency, uptime\) shows green while the product is degrading. Teams discover the problem weeks later via user churn or support tickets. The fundamental issue is that AI's primary failure mode \(semantic incorrectness\) is invisible to syntactic monitoring. Building semantic monitoring is harder and more expensive than traditional observability, but without it you are flying blind on your most important quality metric. This synthesis connects OpenAI's eval framework with production monitoring patterns and the specific observation that LLM degradation is distributional, not binary.
