Mistral Large 3 vs Aion-2.0

Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.

Mistral Large 3 has the cleaner overall profile here, landing at 61 versus 58. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

Mistral Large 3's sharpest advantage is in multimodal & grounded, where it averages 75.5 against 66. The single biggest benchmark swing on the page is MMMU-Pro, 75 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.

Mistral Large 3 is also the more expensive model on tokens at $2.00 input / $6.00 output per 1M tokens, versus $0.80 input / $1.60 output per 1M tokens for Aion-2.0. That is roughly 3.8x on output cost alone.

Quick Verdict

Pick Mistral Large 3 if you want the stronger benchmark profile. Aion-2.0 only becomes the better choice if instruction following is the priority or you want the cheaper token bill.
