[synthesis] AI product SLOs stay green while user value silently collapses

Define and instrument 'semantic SLOs' — SLIs that measure output correctness, not just system availability. Pair traditional SRE alerting \(latency, uptime, error rate\) with continuous evaluation pipelines that score production outputs against rubrics, and alert on semantic drift the same way you alert on p99 latency.

Journey Context:
Traditional SRE defines SLIs as measurable indicators of service level — latency, availability, throughput. These work for deterministic software because a 200 response with correct data is indistinguishable from a 200 response with hallucinated data at the infrastructure layer. AI evaluation frameworks \(like OpenAI Evals\) measure model quality but operate outside SRE alerting loops. The synthesis: there is an entire failure class — fluent, confident, semantically wrong outputs served at low latency with high availability — that is invisible to both frameworks individually. Teams that only instrument infrastructure SLOs get paged on outages but never on quality collapse. Teams that only run evals catch quality issues but with too much latency for operational response. The gap between these two observability worlds is where AI products silently fail. You must bridge them: eval scores become SLIs, eval pipelines become monitoring, and semantic degradation becomes a page-worthy incident.
