Can Mac mini M2 16 GB run Qwen3.5 27B?
16 GB unified · 100 GB/s memory bandwidth · Qwen3.5 27B has 27.8B parameters.
Short answer
No. It doesn't fit in memory.
Needs ≈13 GB but only ≈8.5 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 13 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 16 GB has about 8.5 GB left, so it’s 4.7 GB short.
Ways to make it work
Close everything else
Not enough on its own: with every other app closed it’s still about 1.7 GB short.
Pick a smaller model from the same family
Get more memory
The same chip with 24 GB handles it: Acceptable.
