Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
K-Exaone is clearly ahead on the aggregate, 49 to 35. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
K-Exaone's sharpest advantage is in coding, where it averages 49.4 against 14.5. The single biggest benchmark swing on the page is SWE-bench Verified, 13% to 49.4%.
K-Exaone is the reasoning model in the pair, while DeepSeek V3.1 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. K-Exaone gives you the larger context window at 256K, compared with 128K for DeepSeek V3.1.
Pick K-Exaone if you want the stronger benchmark profile. DeepSeek V3.1 only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
