Practitioners urge correlating offline evals with runtime telemetry to catch real-world regressions

- Observability practitioners urge correlating offline eval metrics with runtime telemetry to measure actual accuracy and task completion in production. (x.com) - Practical rules include tracking quality (hallucination/relevance), outcome (task success), and performance (latency/cost), plus spot‑checking ~10% of outputs with humans. (x.com) - That approach helps teams see where bench evals diverge from user experience and prioritize fixes. (x.com)
