Can Mac mini M2 8 GB run Qwen3.5 4B?
8 GB unified · 100 GB/s memory bandwidth · Qwen3.5 4B has 4.7B parameters.
Short answer
No. It doesn't fit in memory.
Needs ≈3.1 GB but only ≈0.5 GB is available after the OS, other apps and Open WebUI.
Why it doesn’t fit
Even its smallest practical version (3-bit) needs about 3.1 GB for the model, its context memory and the runtime. After macOS (≈3.5 GB), a browser with a few tabs (≈3.0 GB) and Open WebUI (≈1.0 GB), Mac mini M2 8 GB has about 0.5 GB left, so it’s 2.6 GB short.
Ways to make it work
Close everything else
With no other apps open, Qwen3.5 4B runs at 3-bit: Borderline at 30–40 tok/s. Expect the system to feel tight while it’s loaded.
