DeepSeek V3 vs o1-preview

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

o1-preview is clearly ahead on the aggregate, 43 to 25. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

o1-preview's sharpest advantage is in reasoning, where it averages 86.9 against 24.9. The single biggest benchmark swing on the page is SimpleQA, 24.9% to 88%.

o1-preview 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. o1-preview gives you the larger context window at 200K, compared with 128K for DeepSeek V3.

Quick Verdict

Pick o1-preview 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.
