Day 12 of 14 35 minTest setsGradersLLM-as-judge
Measure quality so you know whether a change helped. Build a test set, choose graders (code checks, model-as-judge, humans), score your app, and catch regressions before users do.
By the end of today you can
- Explain why LLM apps need evaluations, not just a few manual tries
- Build a small, realistic test set with expected outcomes
- Choose the right grader - code checks, an LLM judge or a human
- Write a model-as-judge rubric and check it against human labels
- Compare versions to catch regressions before shipping
