Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
o3-mini is clearly ahead on the aggregate, 70 to 57. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
o3-mini's sharpest advantage is in agentic, where it averages 66.6 against 57. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 57% to 67%. MiniMax M2.7 does hit back in coding, so the answer changes if that is the part of the workload you care about most.
o3-mini is also the more expensive model on tokens at $1.10 input / $4.40 output per 1M tokens, versus $0.30 input / $1.20 output per 1M tokens for MiniMax M2.7. That is roughly 3.7x on output cost alone. o3-mini is the reasoning model in the pair, while MiniMax M2.7 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use.
Pick o3-mini if you want the stronger benchmark profile. MiniMax M2.7 only becomes the better choice if coding is the priority or you want the cheaper token bill.
