Background & analysis
On October 20, 2026, Artificial Analysis released and launched AA-PersonalityBench, a new benchmark for the personality of language models. The organization said two models can give equally correct answers and still feel very different to use, and that the benchmark is designed to measure exactly that difference. Evaluation runs along two dimensions: 30 personality traits and 21 communication style characteristics.
The same release described several features on the benchmark page. One is model fingerprints, which show which traits and characteristics are most distinctive for each model compared with all other models evaluated, so readers can quickly see where a model's character stands out. Another is a comparison tool: users can pick any two models and compare them trait by trait on the AA-PersonalityBench page, where each bar shows the probability, based on Elo scores, that one model's answer is preferred over the other's on that trait.
The page also offers a ranking of models across the personality traits, and users can build their own ranking. A full article and methodology notes accompany the results, allowing readers to look at detailed personality dimensions rather than a single overall score. The public information stops there: the benchmark is live and its dimensions, presentation and comparison tools have been announced, but the material does not list the models evaluated or give specific ranking results.
