Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Aion-2.0 is clearly ahead on the aggregate, 58 to 52. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Aion-2.0's sharpest advantage is in instruction following, where it averages 93 against 77. The single biggest benchmark swing on the page is SWE-bench Verified, 35 to 5. Gemini 1.5 Pro does hit back in multimodal & grounded, so the answer changes if that is the part of the workload you care about most.
Gemini 1.5 Pro gives you the larger context window at 2M, compared with 128K for Aion-2.0.
Pick Aion-2.0 if you want the stronger benchmark profile. Gemini 1.5 Pro only becomes the better choice if multimodal & grounded is the priority or you need the larger 2M context window.
