# Pairwise LLM judging

Two models can answer equally correctly and still feel very different to use. AA-PersonalityBench turns that difference into a measurement: 30 personality traits with 30 questions each, 900 in total, answered once by every model with no system prompt, compared pairwise by a blind panel of LLM judges, then rolled into 8 personality indexes covering Expressiveness, Organization, Informativeness, Transparency, Warmth, Conviction, Imagination and Slop, plus 21 communication characteristics measured programmatically from the responses.
