Artificial Analysis reports 11 new points on its Intelligence Index cost frontier

Artificial Analysis reports that this week’s releases of MiMo-V2.6-Pro, Claude Opus 5.5, GPT-6 Luna, and GPT-6 Sol shifted the Pareto frontier between its Intelligence Index and cost per task. Different reasoning efforts produced 11 new frontier points: five from GPT-6 Luna, four from Claude Opus 5.5, and one each from MiMo-V2.6-Pro and GPT-6 Sol.

In the results Artificial Analysis reports, GPT-6 Luna (max) scores 37 at $0.068 per task, MiMo-V2.6-Pro scores 46 at $0.13 per task, and GPT-6 Sol (max) scores 48 at $1.06 per task. Claude Opus 5.5 (max with fallback) scores 58 at $5.98 per task and is the new highest-scoring model on the index.
