Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Grok 4.1 is clearly ahead on the aggregate, 84 to 58. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Grok 4.1's sharpest advantage is in coding, where it averages 73.4 against 33.2. The single biggest benchmark swing on the page is LiveCodeBench, 73 to 29.
Grok 4.1 is also the more expensive model on tokens at $3.00 input / $15.00 output per 1M tokens, versus $0.80 input / $1.60 output per 1M tokens for Aion-2.0. That is roughly 9.4x on output cost alone. Grok 4.1 gives you the larger context window at 1M, compared with 128K for Aion-2.0.
Pick Grok 4.1 if you want the stronger benchmark profile. Aion-2.0 only becomes the better choice if you want the cheaper token bill.
