Pick Grok 4 if you want the stronger benchmark profile. GLM-4.6 only becomes the better choice if you need the larger 200K context window or you want the stronger reasoning-first profile.
Confidence note. This is a partial-evidence comparison with 13 shared benchmark results across 6 evidence categories; 1 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
Grok 4 is clearly ahead on the BenchAlign aggregate, 60.42 to 55.12. 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 15.3 against 3.4. The single biggest benchmark swing on the page is FrontierMath v2 (Tiers 1-3), 3.819% to 19.655%.
GLM-4.6 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. GLM-4.6 gives you the larger context window at 200K, compared with 128K for Grok 4.
