Written by Jakub Rusinowski · Last updated August 15, 2026

Yes

Yes — GLM-Z1 32B (Reasoning) at Q6_K needs about 28.9 GB of the 36 GB usable on MacBook Pro 16" (M4 Max, 48 GB) (~7.1 GB spare), at ~10.7 tok/s (estimated), with room for about 32,768 tokens of context.

Confidence: medium · Recommended quantization: Q6_K · Estimated speed: ~10.7 tok/s

What to watch out for

This model does not publish its full attention configuration, so the KV-cache share of these figures is inferred from its parameter count rather than computed exactly.
Memory on this machine is not upgradeable, so the configuration you buy is the ceiling for every model you will ever run on it.

MacBook Pro M4 Max 48 GB limitations

Unified memory is soldered and cannot be upgraded after purchase.
macOS reserves a share of unified memory for the system, so not all 48 GB is available to a model.

Recommended setup

Ollama or LM Studio (Metal) — MLX for the fastest Apple-native throughput

How these numbers are calculated

Memory need = quantized weights + KV cache at 8,192 tokens (f16) + 0.8 GB runtime overhead.
48 GB unified memory at 546 GB/s, shared between CPU and GPU.
macOS reserves a share of unified memory for the system, so not all of it is available to a model.
Throughput is a memory-bandwidth roofline estimate, not a measurement. It is labelled "estimated" everywhere it appears.
KV cache is inferred from the parameter count because this model does not publish its full attention configuration.
