Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Gemini 3 Pro is clearly ahead on the aggregate, 77 to 58. 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 93.1 against 66. The single biggest benchmark swing on the page is MMMU-Pro, 94 to 61. Aion-2.0 does hit back in instruction following, so the answer changes if that is the part of the workload you care about most.
Gemini 3 Pro gives you the larger context window at 2M, compared with 128K for Aion-2.0.
Pick Gemini 3 Pro if you want the stronger benchmark profile. Aion-2.0 only becomes the better choice if instruction following is the priority.
