What OpenRCA measures and how its scores work.
OpenRCA is a reasoning benchmark for evaluating AI models on root cause analysis tasks across failure cases.
It measures Score as the average ratio of failure cases in which all generated root-cause elements match the ground-truth elements.
Scores are shown in ratio. This benchmark is not independently verified and has an evidence level of B.
