DeepSeek V3 vs Gemini 3 Pro Deep Think

Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.

Gemini 3 Pro Deep Think is clearly ahead on the aggregate, 47 to 25. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Gemini 3 Pro Deep Think's sharpest advantage is in reasoning, where it averages 93.9 against 24.9. The single biggest benchmark swing on the page is SimpleQA, 24.9% to 95%.

Gemini 3 Pro Deep Think is the reasoning model in the pair, while DeepSeek V3 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Gemini 3 Pro Deep Think gives you the larger context window at 2M, compared with 128K for DeepSeek V3.

Quick Verdict

Pick Gemini 3 Pro Deep Think if you want the stronger benchmark profile. DeepSeek V3 only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
