What is…
Evals
Repeatable tests that measure whether an AI system does your task well — the unit tests of AI.
Before trusting an AI workflow, you build a set of real examples with known good answers and score the system against them — automatically where possible, sometimes with another model as judge. Change the prompt or model? Re-run the evals and see if you improved or broke something.
Teams that ship reliable AI products are, almost without exception, teams with good evals.
