Can I run Qwen3 14B on Apple M4 Pro (24GB)?

Compatibility verdict VRAM threshold engine

Yes, it runs GPU accelerated ~24 tok/s est.

Yes. Qwen3 14B runs on Apple M4 Pro (24GB) at Q4_K_M (~10.7 GB of ~16 GB usable).

Needs ~10.7 GB Device usable ~16 GB

Runs at Q4_K_M using ~10.7 GB of ~16 GB usable.

That figure is at a 4k context and moves about ±15% as context length changes. Apple M4 Pro (24GB) leaves ~5.3 GB of headroom.

Running cost · estimate

Power & economics est.

Power draw: ~140 W
Electricity / 1M tokens: ~$0.24
Pays for itself after: ~7,688M tok

At ~$0.15/kWh and the estimated ~24 tok/s, a million generated tokens costs about $0.24 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$1,999 Apple M4 Pro (24GB) pays for itself after roughly 7,688 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

FAQ

Can Apple M4 Pro (24GB) run Qwen3 14B?

Yes. Qwen3 14B runs on Apple M4 Pro (24GB) at Q4_K_M (~10.7 GB of ~16 GB usable).

How much memory does Qwen3 14B need?

Apple M4 Pro (24GB) has room to spare. At Q4_K_M the weights are ~9 GB; with KV cache and runtime overhead, budget ~10.7 GB at a 4k context.

What is the best tool to run Qwen3 14B 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.
