Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
MiniMax M2.5 is clearly ahead on the aggregate, 37 to 23. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
MiniMax M2.5's sharpest advantage is in reasoning, where it averages 68.9 against 21.7. The single biggest benchmark swing on the page is SimpleQA, 21.7% to 70%. Grok 3 Mini does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
MiniMax M2.5 is also the more expensive model on tokens at $0.30 input / $1.20 output per 1M tokens, versus $0.30 input / $0.50 output per 1M tokens for Grok 3 Mini. That is roughly 2.4x on output cost alone.
Pick MiniMax M2.5 if you want the stronger benchmark profile. Grok 3 Mini only becomes the better choice if knowledge is the priority or you want the cheaper token bill.
