Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.
Nova Pro is clearly ahead on the aggregate, 40 to 35. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Nova Pro's sharpest advantage is in mathematics, where it averages 42.4 against 23.1. The single biggest benchmark swing on the page is MMLU, 41 to 87.5. GPT-4.1 mini does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
GPT-4.1 mini gives you the larger context window at 1M, compared with 128K for Nova Pro.
Pick Nova Pro if you want the stronger benchmark profile. GPT-4.1 mini only becomes the better choice if knowledge is the priority or you need the larger 1M context window.
