Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Gemini 3 Flash is clearly ahead on the aggregate, 62 to 53. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Gemini 3 Flash's sharpest advantage is in coding, where it averages 40.4 against 24.7. The single biggest benchmark swing on the page is SWE-bench Verified, 44 to 22.
Gemini 3 Flash is also the more expensive model on tokens at $0.50 input / $3.00 output per 1M tokens, versus $0.10 input / $0.40 output per 1M tokens for Seed-2.0-Mini. That is roughly 7.5x on output cost alone. Gemini 3 Flash gives you the larger context window at 1M, compared with 256K for Seed-2.0-Mini.
Pick Gemini 3 Flash if you want the stronger benchmark profile. Seed-2.0-Mini only becomes the better choice if you want the cheaper token bill.
