What this site is for
ML Observe covers ML observability and MLOps from a production-engineering perspective. Here's what we publish.
ML Observe covers ML observability and MLOps from inside production engineering. The kind of writing we wanted to find when we were debugging a model that worked in eval and broke in prod.
What we publish:
Drift, the unsexy version. Concept drift, label drift, feature drift, training/serving skew. How to detect it in real systems, what thresholds actually catch problems, why most monitoring dashboards lie about it.
Production failure writeups. When models go wrong in the real world — silently degraded predictions, retraining loops gone bad, embedding-store corruption, vector-DB consistency issues — postmortems we wish vendors would publish.
Tooling reviews, honest. Arize, Fiddler, WhyLabs, Evidently, NannyML, Aporia, the open-source observability stack. Where each helps, where it solves problems you don’t have, what to install when you’re starting from zero.
MLOps without the hype cycle. Feature stores, model registries, evaluation pipelines, online inference. What’s worth adopting, what’s reinventing things SREs solved a decade ago, what’s genuinely new.
What we don’t publish:
- Vendor-sponsored “thought leadership”
- “Top 10 MLOps tools” listicles
- Anything we couldn’t show running in production

Closing the Eval-Prod Gap: Online Evaluation as Observability
Offline eval scores are green and production is worse. The gap is not a measurement error — it is structural. Here is how to instrument online evaluation so production quality becomes observable.

RAG systems fail at the embedding and index layer long before the LLM does. Here is what to actually monitor: embedding drift, index staleness, recall decay, and retrieval quality in production.
