Why this result
Gemini 3 Pro is clearly ahead on the BenchAlign aggregate, 67.73 to 57.01. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Gemini 3 Pro's sharpest advantage is in multimodal & grounded, where it averages 81.1 against 79.6. The single biggest benchmark swing on the page is MMMU-Pro, 81% to 79%. Qwen3.5 397B does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.
Gemini 3 Pro is also the more expensive model on tokens at $2.00 input / $12.00 output per 1M tokens, versus $0.60 input / $3.60 output per 1M tokens for Qwen3.5 397B. That is roughly 3.3x on output cost alone. Gemini 3 Pro gives you the larger context window at 2M, compared with 128K for Qwen3.5 397B.
