The AI user's guide to evals

Technically • 14 implied HN points • 11 Dec 25
🕹 Technology Software
  1. Evals are software tests for AI that turn fuzzy model outputs into measurable metrics so you can find and fix errors instead of guessing.
  2. Look at your data first — analyze real outputs to spot where the model fails, because you can’t measure or fix problems you don’t identify.
  3. Start with simple keyword checks and assertions before building complex “LLM-as-judge” setups, and iterate: test, fix, measure, repeat; otherwise your system just feels like a slot machine.

Use it or lose it

The Engineering Manager • 13 implied HN points • 14 Dec 25
🕹 Technology Software
