Why this result
Gemini 3.1 Pro is clearly ahead on the BenchAlign aggregate, 54.7 to 43.1. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Gemini 3.1 Pro's sharpest advantage is in mathematics, where it averages 31.8 against 4.5. The single biggest benchmark swing on the page is FrontierMath v2 (Tiers 1-3), 36.900% to 4.483%.
Gemini 3.1 Pro is also the more expensive model on tokens at $2.00 input / $12.00 output per 1M tokens, versus $0.40 input / $1.60 output per 1M tokens for GPT-4.1 mini. That is roughly 7.5x on output cost alone.
