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 38. 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 68. The single biggest benchmark swing on the page is OpenBookQA, 75 to 41.
Aion-2.0 is also the more expensive model on tokens at $0.80 input / $1.60 output per 1M tokens, versus $0.03 input / $0.12 output per 1M tokens for LFM2-24B-A2B. That is roughly 13.3x on output cost alone. Aion-2.0 gives you the larger context window at 128K, compared with 32K for LFM2-24B-A2B.
Pick Aion-2.0 if you want the stronger benchmark profile. LFM2-24B-A2B only becomes the better choice if you want the cheaper token bill.
