Move beyond vibe-checks — build systematic offline and online eval pipelines that give you confidence before and after every deployment.
Five passes over the same idea, each from a different angle. Do them in order, or jump to whichever you need.
Evaluating LLMs rigorously is the difference between shipping responsibly and shipping blind. Offline evals run a golden dataset against your pipeline before deploy. Online evals watch production traffic for regressions. The hard part is deciding what "good" means for your task — and building evaluators that are themselves reliable.
