Can I run GLM-4.6 on Apple M5 (16GB)?

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

No. GLM-4.6 needs ~221.3 GB even at Q4_K_M, but Apple M5 (16GB) only has ~10.5 GB usable.

Needs ~221.3 GB Device usable ~10.5 GB

Needs ~221.3 GB even at Q4_K_M, but only ~10.5 GB is usable.

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

The gap is about 210.8 GB: GLM-4.6 needs roughly 221.3 GB at Q4_K_M and Apple M5 (16GB) leaves only about 10.5 GB usable for a model. No single tracked device has enough memory; GLM-4.6 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 M5 (16GB) run GLM-4.6?

No. GLM-4.6 needs ~221.3 GB even at Q4_K_M, but Apple M5 (16GB) only has ~10.5 GB usable.

How much memory does GLM-4.6 need?

Apple M5 (16GB) does not have enough memory. At Q4_K_M the weights are ~216 GB; with KV cache and runtime overhead, budget ~221.3 GB at a 4k context. It is a Mixture-of-Experts model (357B total / 32B active), so all experts must stay in memory; memory tracks total params, not active params.

What is the best tool to run GLM-4.6 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.
