Aion-2.0 vs Ministral 3 3B (Reasoning)

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 31. 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 multimodal & grounded, where it averages 66 against 30.4. The single biggest benchmark swing on the page is OpenBookQA, 75 to 20.

Aion-2.0 is also the more expensive model on tokens at $0.80 input / $1.60 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Ministral 3 3B (Reasoning). That is roughly Infinityx on output cost alone. Ministral 3 3B (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.

Quick Verdict

Pick Aion-2.0 if you want the stronger benchmark profile. Ministral 3 3B (Reasoning) only becomes the better choice if you want the cheaper token bill or you want the stronger reasoning-first profile.
