Notes

Methodology

This adapter reads the public Artificial Analysis homepage payload, prioritizes rows explicitly marked as frontier models and fills the configured display set from the highest-scored homepage rows when fewer frontier rows are exposed, ranks them by the current Artificial Analysis Intelligence Index, and plots them by release date so the skyline updates when Artificial Analysis publishes new model evaluations.

Observed 5 Artificial Analysis frontier model rows and 14 scored display rows at 2026-06-26T06:53:34.586Z; source manifest 1773f3a02bf61a3d97b51f72ac5a2127bebb2211d106b0aaaa87c33baf14868d.
