Z.ai (Zhipu AI)GLM-4.5VSZ.ai (Zhipu AI)GLM-5
Our Take
We recommend GLM-4.5 for practical local execution on standard developer hardware, or GLM-5 if you need peak reasoning and have the VRAM (or a cloud API) to host it. While GLM-5 offers frontier capability, its massive parameter size makes it extremely difficult to host locally. Choose GLM-4.5 for standard local setups, or GLM-5 for peak reasoning.
▶WHY?
Benchmark Calculations & Evidence:
Model Size: GLM-5 is a massive 754B parameter model requiring heavy GPU infrastructure, while GLM-4.5 is a 358B parameter model.
