Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
o3-pro is clearly ahead on the aggregate, 45 to 23. 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 21.7. The single biggest benchmark swing on the page is SimpleQA, 21.7% to 86%.
o3-pro is the reasoning model in the pair, while Grok 3 Mini 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 Grok 3 Mini.
Pick o3-pro if you want the stronger benchmark profile. Grok 3 Mini only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
