Opus 5.5 scores 58 on Artificial Analysis, 12 points above the best open model MiMo 2.6 Pro and a big jump from Fable 5.1. A Reddit user estimates that if open models keep their recent pace (44→46 in two months), they could close the gap in roughly 4–6 months as labs scale GPUs, parameters, data and architecture improvements.
