Can I run Qwen3 0.6B on Apple M3 Pro (18GB)?
Yes. Qwen3 0.6B runs on Apple M3 Pro (18GB) at Q4_K_M (~1.5 GB of ~12 GB usable).
Runs at Q4_K_M using ~1.5 GB of ~12 GB usable. You have room for FP16 for higher quality.
That figure is at a 4k context and moves about ±15% as context length changes. Apple M3 Pro (18GB) leaves ~10.5 GB of headroom, room to step up to FP16 for higher quality.

Running cost · estimate

- Pays for itself after
- ~2,706M tok
At ~$0.15/kWh and the estimated ~167 tok/s, a million generated tokens costs about $0.02 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$1,299 Apple M3 Pro (18GB) pays for itself after roughly 2,706 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 M3 Pro (18GB) run Qwen3 0.6B?
Yes. Qwen3 0.6B runs on Apple M3 Pro (18GB) at Q4_K_M (~1.5 GB of ~12 GB usable).
How much memory does Qwen3 0.6B need?
Apple M3 Pro (18GB) has room to spare. At Q4_K_M the weights are ~0.48 GB; with KV cache and runtime overhead, budget ~1.5 GB at a 4k context.
What is the best tool to run Qwen3 0.6B 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.
