The hard part is designing experiments and evaluations that you can trust enough to know whether the new model is actually an improvement.By: Baharak SaberidokhtIntroductionShipping a production LLM system means iterating fast on improvements to something that is, by construction, non-deterministic. Models drift, judges disagree with themselves, references regenerate as different strings, and bugs may persist until the next release, because retraining takes weeks. Most of this friction comes from infrastructure challenges, not model quality, and the fixes come from classical software engineering techniques.At Airbnb, we built reliable LLM infrastructure by …
