Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
o3-pro is clearly ahead on the aggregate, 71 to 53. 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 coding, where it averages 49.2 against 24.7. The single biggest benchmark swing on the page is GPQA, 89 to 61.
o3-pro is the reasoning model in the pair, while Seed-2.0-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. Seed-2.0-Mini gives you the larger context window at 256K, compared with 200K for o3-pro.
Pick o3-pro if you want the stronger benchmark profile. Seed-2.0-Mini only becomes the better choice if you need the larger 256K context window or you would rather avoid the extra latency and token burn of a reasoning model.
