Can I run Qwen3-Coder 30B-A3B on Apple M5 (32GB)?
Yes. Qwen3-Coder 30B-A3B runs on Apple M5 (32GB) at Q4_K_M (~19.4 GB of ~21 GB usable).
Fits at Q4_K_M (~19.4 GB of ~21 GB usable) but with little headroom. Close other apps, or drop to a 2k context to free about a gigabyte.
That figure is at a 4k context and moves about ±15% as context length changes. Apple M5 (32GB) leaves ~1.6 GB of headroom.

FAQ
Can Apple M5 (32GB) run Qwen3-Coder 30B-A3B?
Yes. Qwen3-Coder 30B-A3B runs on Apple M5 (32GB) at Q4_K_M (~19.4 GB of ~21 GB usable).
How much memory does Qwen3-Coder 30B-A3B need?
It is a tight fit on Apple M5 (32GB). At Q4_K_M the weights are ~17.28 GB; with KV cache and runtime overhead, budget ~19.4 GB at a 4k context. It is a Mixture-of-Experts model (30.5B total / 3.3B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Qwen3-Coder 30B-A3B on macOS?
LM Studio for a simple setup; mlx-lm for the most speed. vLLM is NOT a Mac tool, it is a CUDA/Linux serving engine. Unified memory is not a fixed VRAM slice; ~70% is usable for weights.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
