Some of these are scored by an AI judge, not just an automatic check — the methodology page explains exactly how each number is measured.

Fabrication / groundedness

0.90 invented claims per clean report on average (95% CI [0.6–1.2]) · flagged on 50.0% of judged reports · groundedness score 50.0 (95% CI [36.7–63.3]).

A fabrication is a concrete claim the judge panel could not trace to any source this model was given — every BaitBench product is fictional, so there is no legitimate outside knowledge to fall back on. Each report's count is the MEDIAN of 5 independent judges (median consensus, not majority voting — see the methodology page).
