Can MacBook Pro M3 Pro 18 GB run Qwen3-Coder 30B-A3B Instruct?
18 GB unified · 150 GB/s memory bandwidth · Qwen3-Coder 30B-A3B Instruct has 30.5B parameters (3.3B active per token).
Short answer
No. It doesn't fit in memory.
Needs ≈14 GB but only ≈11 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 14 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), MacBook Pro M3 Pro 18 GB has about 11 GB left, so it’s 3.7 GB short.
Ways to make it work
Close everything else
Not enough on its own: with every other app closed it’s still about 0.7 GB short.
