Artificial Analysis Decision Index v2 Released with New Decision Score and Private Benchmarks

Artificial Analysis released Decision Index v2, with 45% of the Index now built on private datasets, up from 25% in v1. Drex Max v1.1 from Nace AI narrowly leads decision models at 73, within 1 point of GLiDE v1.2 and Mammoth 27B. The new Decision Score rewards both correctness and calibrated confidence, while AA-Paperclip and AA-Symmetry add private document and consistency tests.
