Written by Jakub Rusinowski · Last updated February 24, 2026

Yes

Yes — Qwen 3.5 35B-A3B at Q8_0 needs about 39.9 GB of the 48 GB usable on Mac mini (M4 Pro, 64 GB) (~8.1 GB spare), at ~32.7 tok/s (estimated), with room for about 32,768 tokens of context.

Confidence: medium · Recommended quantization: Q8_0 · Estimated speed: ~32.7 tok/s

What to watch out for

2 larger variants of Qwen 3.5 do not fit and would need CPU offload or different hardware.
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.

Mac mini M4 Pro 64 GB limitations

M4 Pro memory bandwidth is half the M4 Max's, so large models that fit will still generate roughly half as fast.

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.
64 GB unified memory at 273 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.

FAQ

Can I run Qwen 3.5 on Mac mini (M4 Pro, 64 GB)?

Yes — Qwen 3.5 35B-A3B at Q8_0 needs about 39.9 GB of the 48 GB usable on Mac mini (M4 Pro, 64 GB) (~8.1 GB spare), at ~32.7 tok/s (estimated), with room for about 32,768 tokens of context.
