Same CV, same judge, ten reruns: the score moved from 0 to 75 and the CI gate flipped. Temperature zero will not save you. Here are the three dials that actually change the number — and how to turn them until a rerun is boring.
We ran Aegis bias 640 times on one planted example, across nine models and multiple reasoning levels. Higher reasoning helped some judges and made others more lenient — and they still disagreed about nationality confidence.
Five practical metric areas (relevance, factual groundedness, faithfulness to sources, safety, and instruction compliance) that most production LLM stacks should track.

On the same ordered test cases and thresholds, we compared pass/fail labels across frameworks. Agreement ranged from strong alignment on several suites to sharp splits where rubrics measure different things.
A straight path from deciding what you measure to running your metric on real data, with room to learn from tooling and published work along the way.
Measures LLM or agent performance to ensure reliable, safe, and production-ready behavior, while helping identify issues and guide improvements.
