Can I run GLM-5.2 on Apple M4 Max (64GB)?

Compatibility verdict VRAM threshold engine
No, not enough memory would not load

No. GLM-5.2 needs ~473.1 GB even at Q4_K_M, but Apple M4 Max (64GB) only has ~48 GB usable.

Needs ~473.1 GB Device usable ~48 GB

Needs ~473.1 GB even at Q4_K_M, but only ~48 GB is usable.

That figure is at a 4k context and moves about ±15% as context length changes.

The gap is about 425.1 GB: GLM-5.2 needs roughly 473.1 GB at Q4_K_M and Apple M4 Max (64GB) leaves only about 48 GB usable for a model. No single tracked device has enough memory; GLM-5.2 needs a multi-GPU or high-memory rig.

How to run it

On macOS use LM Studio (Polished GUI, ships MLX on Apple Silicon, one-click model downloads.).

FAQ

Can Apple M4 Max (64GB) run GLM-5.2?

No. GLM-5.2 needs ~473.1 GB even at Q4_K_M, but Apple M4 Max (64GB) only has ~48 GB usable.

How much memory does GLM-5.2 need?

Apple M4 Max (64GB) does not have enough memory. At Q4_K_M the weights are ~465.83 GB; with KV cache and runtime overhead, budget ~473.1 GB at a 4k context. It is a Mixture-of-Experts model (744B total / 40B active), so all experts must stay in memory; memory tracks total params, not active params.

What is the best tool to run GLM-5.2 on macOS?

LM Studio for a simple setup; mlx-lm for the most speed. vLLM is NOT a Mac tool, it is a CUDA/Linux serving engine. Unified memory is not a fixed VRAM slice; ~70% is usable for weights.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
