Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
GPT-4.1 is clearly ahead on the aggregate, 65 to 53. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-4.1's sharpest advantage is in coding, where it averages 51.7 against 24.7. The single biggest benchmark swing on the page is AIME 2024, 26.4 to 64. Seed-2.0-Mini does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.
GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $0.10 input / $0.40 output per 1M tokens for Seed-2.0-Mini. That is roughly 20.0x on output cost alone. GPT-4.1 gives you the larger context window at 1M, compared with 256K for Seed-2.0-Mini.
Pick GPT-4.1 if you want the stronger benchmark profile. Seed-2.0-Mini only becomes the better choice if mathematics is the priority or you want the cheaper token bill.
