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 41. 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 mathematics, where it averages 72.1 against 46.1. The single biggest benchmark swing on the page is OpenBookQA, 75 to 29.
DeepSeek V3.1 (Reasoning) is the reasoning model in the pair, while Aion-2.0 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.
Pick Aion-2.0 if you want the stronger benchmark profile. DeepSeek V3.1 (Reasoning) only becomes the better choice if you want the stronger reasoning-first profile.
