You wouldn't ship code without tests — but most teams ship LLM features on "looks good to me." Evaluations (evals) fix that: you define test cases and pass/fail criteria, then measure your model objectively — catching regressions, comparing models, and gating deploys.

In this guide you'll build a real eval harness with Promptfoo pointed at the WEC Inference API — the same OpenAI-compatible endpoint you call from your apps. Everything here was run live against https://inference.wiline.com; the outputs are real.
