## AI overview

A tutorial on building automated evaluation pipelines for LLM applications, focusing on why conventional deterministic tests are inadequate for variable model outputs.

## Source excerpt

So you shipped your AI feature and it works in demos. Your team is impressed. Then a user asks a question slightly outside your test cases and the model confidently returns something completely wrong.
