DeepSeek V3 vs DeepSeek V3.1 (Reasoning)

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

DeepSeek V3.1 (Reasoning) is clearly ahead on the aggregate, 32 to 25. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

DeepSeek V3.1 (Reasoning)'s sharpest advantage is in reasoning, where it averages 58.2 against 24.9. The single biggest benchmark swing on the page is SimpleQA, 24.9% to 93.4%. DeepSeek V3 does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.

DeepSeek V3.1 (Reasoning) 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.

Quick Verdict

Pick DeepSeek V3.1 (Reasoning) if you want the stronger benchmark profile. DeepSeek V3 only becomes the better choice if mathematics is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
