GLM-4.7-Flash struggled on my 16GB Mac. Then I found out the flagship GLM model needs more memory than my entire house has RAM for combined. Here’s the honest hardware math nobody puts in one place. #
I wanted to try Zhipu AI’s GLM models locally — they’ve had real momentum in the open-weight world. So I pulled GLM-4.7-Flash, the version every guide calls the laptop-friendly one, onto my 16GB Apple Silicon Mac.
It ran. It also struggled — noticeably slower than the similarly-sized Qwen model I’d already been using on the same machine for the same kind of work. And that sent me down a rabbit hole, because I wanted to know why, and what my actual options were if I wanted a smoother GLM experience. What I found genuinely surprised me: “GLM” isn’t one hardware requirement. It’s a name stretched across models that differ by roughly six thousand times in size. Let me walk through what I found, because I think a lot of people are about to make the same mistake I did.
