Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Gemini 3.1 Pro is clearly ahead on the aggregate, 84 to 53. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Gemini 3.1 Pro's sharpest advantage is in coding, where it averages 71.9 against 24.7. The single biggest benchmark swing on the page is SWE-bench Verified, 75 to 22.
Gemini 3.1 Pro is also the more expensive model on tokens at $1.25 input / $5.00 output per 1M tokens, versus $0.10 input / $0.40 output per 1M tokens for Seed-2.0-Mini. That is roughly 12.5x on output cost alone. Gemini 3.1 Pro gives you the larger context window at 1M, compared with 256K for Seed-2.0-Mini.
Pick Gemini 3.1 Pro if you want the stronger benchmark profile. Seed-2.0-Mini only becomes the better choice if you want the cheaper token bill.
