Gemini 3 Pro vs GLM-4.6
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
Google · Nov 2025
Google's November 2025 frontier breakout — 91.9% GPQA Diamond and 37.5% HLE made it the reasoning leader of its generation.
Z.ai (Zhipu) · Sep 2025
The budget coding-agent favorite of late 2025 — near-Sonnet coding utility with MIT weights and a $3/month plan.
The verdict
Gemini 3 Pro wins 5 of the 5 benchmarks these models share, against 0 for GLM-4.6. On price the gap is dramatic: GLM-4.6 works out roughly 4.5x cheaper per blended million tokens. Gemini 3 Pro also takes 1M of context versus 200K for GLM-4.6. And GLM-4.6 is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
