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 63. 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 41.4. The single biggest benchmark swing on the page is LiveCodeBench, 71 to 37.
Gemini 3.1 Pro is also the more expensive model on tokens at $1.25 input / $5.00 output per 1M tokens, versus $0.25 input / $2.00 output per 1M tokens for Seed-2.0-Lite. That is roughly 2.5x on output cost alone. Gemini 3.1 Pro gives you the larger context window at 1M, compared with 256K for Seed-2.0-Lite.
Pick Gemini 3.1 Pro if you want the stronger benchmark profile. Seed-2.0-Lite only becomes the better choice if you want the cheaper token bill.
