Latest update (11-08 00:00): Artificial Analysis releases Decision Index v2 with a calibration-based score

Overview: Artificial Analysis released Decision Index v2, which moves 45% of its weight onto private datasets and adds a Decision Score that rewards correct answers and calibrated confidence. The company says the change better reflects real-world utility and guards against benchmark gaming.

In the post, Drex Max v1.1 from Nace AI, GLiDE v1.2 from Fastino Labs and Mammoth 27B from Baseten sit within one point at the top. Claude Haiku 5.5 (Max) scores 77 and GPT-6 Luna (Max) scores 76, but the post says each costs about 15 times more per 1M tasks than Drex Max v1.1.
