Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.
DeepSeekMath V2 is clearly ahead on the aggregate, 71 to 56. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
DeepSeekMath V2's sharpest advantage is in coding, where it averages 53.7 against 49.3. The single biggest benchmark swing on the page is IFEval, 83 to 93.9. o3-mini does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
o3-mini gives you the larger context window at 200K, compared with 128K for DeepSeekMath V2.
Pick DeepSeekMath V2 if you want the stronger benchmark profile. o3-mini only becomes the better choice if knowledge is the priority or you need the larger 200K context window.
