Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
o4-mini (high) is clearly ahead on the aggregate, 63 to 53. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
o4-mini (high)'s sharpest advantage is in mathematics, where it averages 82.9 against 65.1. The single biggest benchmark swing on the page is SWE-bench Verified, 45 to 22. Seed-2.0-Mini does hit back in multimodal & grounded, so the answer changes if that is the part of the workload you care about most.
Seed-2.0-Mini gives you the larger context window at 256K, compared with 200K for o4-mini (high).
Pick o4-mini (high) if you want the stronger benchmark profile. Seed-2.0-Mini only becomes the better choice if multimodal & grounded is the priority or you need the larger 256K context window.
