Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Qwen2.5-72B is clearly ahead on the aggregate, 64 to 58. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Qwen2.5-72B's sharpest advantage is in mathematics, where it averages 83.5 against 72.1. The single biggest benchmark swing on the page is MATH-500, 84 to 71. 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.
Pick Qwen2.5-72B if you want the stronger benchmark profile. Aion-2.0 only becomes the better choice if instruction following is the priority.
