Gemini 2.5 Pro vs GLM-5
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
Google · Mar 2025
Google's 2025 workhorse flagship — first mainstream thinking model with a 1M context, still widely deployed.
Z.ai (Zhipu) · Feb 2026
Z.ai's 744B open-weights MoE — within ~4 points of Opus 4.6 on SWE-bench Verified at $1/$3.20 per million tokens.
The verdict
GLM-5 wins 1 of the 1 benchmarks these models share, against 0 for Gemini 2.5 Pro. GLM-5 is about 2.2x cheaper per blended million tokens (3:1 input:output mix). Gemini 2.5 Pro also takes 1.0M of context versus 200K for GLM-5. And GLM-5 is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
