Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
K-Exaone has the cleaner overall profile here, landing at 49 versus 47. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
K-Exaone's sharpest advantage is in coding, where it averages 49.4 against 26.1. The single biggest benchmark swing on the page is SWE-bench Verified, 49.4% to 33%.
K-Exaone is the reasoning model in the pair, while Z-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 Z-1.
Pick K-Exaone if you want the stronger benchmark profile. Z-1 only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
