Evals that teams actually use
Good evals don’t just grade — they guide. How we build lightweight suites that improve models and workflows.
An eval nobody runs is decoration. We keep suites small enough that a busy operator will open them when something feels off.
Each case is a real task, a pass/fail the team can argue with, and a note about what “wrong” looks like. That is enough to stop silent regressions after a prompt change.
We do not wait for a research bench. We want the next Tuesday’s work to be slightly less guessy than last Tuesday’s.
