Evaluations
Living leaderboards from our evaluation work — interactive, multi-dimensional, and grounded in real human judgement at population scale.
Human evaluation
A demographically-aware, multi-dimensional human-preference leaderboard: 27 models judged by 20,000+ stratified participants and ranked with a hierarchical Bradley–Terry–Davidson model. Compare models head-to-head, by metric, and across 22 demographic groups.
Alignment
Behavioural alignment evaluated under realistic pressure — 904 multi-turn scenarios across Honesty, Safety, Non-Manipulation, Robustness, Corrigibility, and Scheming. Ranks how models actually behave when instructions conflict, not what they claim they would do.
Health evaluation
How the public uses and judges AI for their health, and how the same models hold up when practising clinicians check the advice: where models' health advice goes wrong, what people ask and reward, and why AI judges need checking against clinicians.
