Why this result
Gemini 2.5 Pro has the cleaner BenchAlign overall profile here, landing at 57.25 versus 55.12. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
Gemini 2.5 Pro's sharpest advantage is in mathematics, where it averages 11.6 against 3.4. The single biggest benchmark swing on the page is FrontierMath v2 (Tiers 1-3), 14.138% to 3.819%.
GLM-4.6 is the reasoning model in the pair, while Gemini 2.5 Pro 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. Gemini 2.5 Pro gives you the larger context window at 1M, compared with 200K for GLM-4.6.
