Can Mac mini M4 Pro 48 GB run GLM-5.3 (753B-A40B)?
48 GB unified · 273 GB/s memory bandwidth · GLM-5.3 (753B-A40B) has 753B parameters (40B active per token).
Short answer
No. It doesn't fit in memory.
Needs ≈312 GB but only ≈39 GB is available after the OS, other apps and Open WebUI.
Why it doesn’t fit
Even its smallest practical version (3-bit) needs about 312 GB for the model, its context memory and the runtime. After macOS (≈4.8 GB), a browser with a few tabs (≈3.0 GB) and Open WebUI (≈1.0 GB), Mac mini M4 Pro 48 GB has about 39 GB left, so it’s 273 GB short.
Ways to make it work
Close everything else
Not enough on its own: with every other app closed it’s still about 270 GB short.
