Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Gemini 3 Flash is clearly ahead on the aggregate, 45 to 25. 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 reasoning, where it averages 65.9 against 24.9. The single biggest benchmark swing on the page is SimpleQA, 24.9% to 67%. DeepSeek V3 does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.
Gemini 3 Flash is also the more expensive model on tokens at $0.50 input / $3.00 output per 1M tokens, versus $0.27 input / $1.10 output per 1M tokens for DeepSeek V3. That is roughly 2.7x on output cost alone. Gemini 3 Flash gives you the larger context window at 1M, compared with 128K for DeepSeek V3.
Pick Gemini 3 Flash if you want the stronger benchmark profile. DeepSeek V3 only becomes the better choice if mathematics is the priority or you want the cheaper token bill.
