Why this result
Gemini 3.1 Pro is clearly ahead on the BenchAlign aggregate, 54.7 to 47.14. 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 9.3. The single biggest benchmark swing on the page is FrontierMath v2 (Tiers 1-3), 36.900% to 9.310%.
o1 is also the more expensive model on tokens at $15.00 input / $60.00 output per 1M tokens, versus $2.00 input / $12.00 output per 1M tokens for Gemini 3.1 Pro. That is roughly 5.0x on output cost alone. o1 is the reasoning model in the pair, while Gemini 3.1 Pro is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Gemini 3.1 Pro gives you the larger context window at 1M, compared with 200K for o1.
