Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Grok 4 is clearly ahead on the aggregate, 66 to 56. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Grok 4's sharpest advantage is in mathematics, where it averages 85.1 against 67.1. The single biggest benchmark swing on the page is SWE-bench Verified, 48 to 24.
Seed 1.6 Flash is the reasoning model in the pair, while Grok 4 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. Seed 1.6 Flash gives you the larger context window at 256K, compared with 128K for Grok 4.
Pick Grok 4 if you want the stronger benchmark profile. Seed 1.6 Flash only becomes the better choice if you need the larger 256K context window or you want the stronger reasoning-first profile.
