Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
o3-pro is clearly ahead on the aggregate, 45 to 25. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
o3-pro's sharpest advantage is in reasoning, where it averages 84.9 against 24.9. The single biggest benchmark swing on the page is SimpleQA, 24.9% to 86%. DeepSeek V3 does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.
o3-pro is the reasoning model in the pair, while DeepSeek V3 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. o3-pro gives you the larger context window at 200K, compared with 128K for DeepSeek V3.
Pick o3-pro if you want the stronger benchmark profile. DeepSeek V3 only becomes the better choice if mathematics is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
