Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Seed-2.0-Mini is clearly ahead on the aggregate, 53 to 44. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Seed-2.0-Mini's sharpest advantage is in mathematics, where it averages 65.1 against 48.3. The single biggest benchmark swing on the page is HumanEval, 55 to 30. Claude 4.1 Opus Thinking does hit back in agentic, so the answer changes if that is the part of the workload you care about most.
Claude 4.1 Opus Thinking 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 Claude 4.1 Opus Thinking.
Pick Seed-2.0-Mini if you want the stronger benchmark profile. Claude 4.1 Opus Thinking only becomes the better choice if agentic is the priority or you want the stronger reasoning-first profile.
