MiniMax M2.5 vs GPT-4o mini

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

MiniMax M2.5 is clearly ahead on the aggregate, 66 to 43. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

MiniMax M2.5 is also the more expensive model on tokens at $0.30 input / $1.20 output per 1M tokens, versus $0.15 input / $0.60 output per 1M tokens for GPT-4o mini. That is roughly 2.0x on output cost alone.

Quick Verdict

Pick MiniMax M2.5 if you want the stronger benchmark profile. GPT-4o mini only becomes the better choice if coding is the priority or you want the cheaper token bill.
