With memory offload — actual speed may be lowerWhat limits this setup
Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 482.2 GB, but this setup only exposes 46.1 GB of usable shared or unified memory.
Best improvement path
Move to a larger memory pool
A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.

Frequently asked questions
Can MacBook Pro M4 Pro 64GB run GLM-5?
No, GLM-5 requires more memory than MacBook Pro M4 Pro 64GB provides.
How much VRAM does GLM-5 need?
GLM-5 (744B parameters) requires approximately 482.2 GB of memory with Q4_K_M quantization.
What is the best quantization for GLM-5?
The recommended quantization for GLM-5 is Q4_K_M, which balances quality and memory efficiency.
What speed will GLM-5 run at on MacBook Pro M4 Pro 64GB?
On MacBook Pro M4 Pro 64GB, GLM-5 achieves approximately 2.0 tokens per second decode speed with a time-to-first-token of 96800ms using Q4_K_M quantization.
Can MacBook Pro M4 Pro 64GB run GLM-5 for coding?
For coding workloads, GLM-5 on MacBook Pro M4 Pro 64GB receives a F grade with 2.0 tok/s and 4K context.
What context window can GLM-5 use on MacBook Pro M4 Pro 64GB?
On MacBook Pro M4 Pro 64GB, GLM-5 can safely use up to 4K tokens of context. The model's official context limit is 200K, but available memory constrains the safe maximum.
What should I upgrade first if GLM-5 feels slow on MacBook Pro M4 Pro 64GB?
Move to a larger memory pool. A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.
Is unified memory on MacBook Pro M4 Pro 64GB as fast as VRAM for GLM-5?
Not always. MacBook Pro M4 Pro 64GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
