DeepSeekDeepSeek V4 ProVSZ.ai (Zhipu AI)GLM-5.1
Our Take
We recommend GLM-5.1 for practical local execution on standard developer hardware, or DeepSeek V4 Pro if you need peak reasoning and have the VRAM (or a cloud API) to host it. While DeepSeek V4 Pro offers frontier capability, its massive parameter size makes it extremely difficult to host locally. Choose GLM-5.1 for standard local setups, or DeepSeek V4 Pro for peak reasoning.
▶WHY?
Benchmark Calculations & Evidence:
Model Size: DeepSeek V4 Pro is a massive 1600B parameter model requiring heavy GPU infrastructure, while GLM-5.1 is a 754B parameter model.
