**Yes, but it is tight.** Qwen3-14B at Q4\_K\_M needs about 11.3 GB, and the Mac mini M6 16GB has 12.0 GB usable at a \~4k context.

# Can I run Qwen3-14B on a Mac mini 16GB?

Qwen3-14B at Q4\_K\_M needs about 11.3 GB, and the Mac mini M6 16GB has 12.0 GB usable. That figure is 16 GB of unified memory on the spec sheet, of which 12.0 GB is usable for weights and cache, at 153 GB/s memory bandwidth. Alibaba’s 14B Qwen3\. It sits in the sweet spot for 12–16 GB cards that want more quality than an 8B. These are estimates from [our formula](https://whatcanirunai.vercel.app/method/), not measured benchmarks.

## Memory at each quant

| Quant    | Need vs 12.0 GB | Verdict       |
| -------- | --------------- | ------------- |
| Q4\_K\_M | 11.3 GB         | Q4Tight       |
| Q8\_0    | 19.0 GB         | Q8Won’t fit   |
| FP16     | 35.0 GB         | FP16Won’t fit |

## Estimated tokens per second

Estimate: **8–14 tokens/sec** at Q4\_K\_M. This is a bandwidth-derived range, not a bench. Efficiency is a 45–80% unified-memory band from [How we calculate](https://whatcanirunai.vercel.app/method/).

## Context headroom

At Q4\_K\_M, this machine has headroom out to about **8k tokens** under our KV estimate. Longer chats need more memory for the cache. Figures assume an FP16 KV cache.

## What to do instead

* Run [Phi-4](https://whatcanirunai.vercel.app/can-i-run/phi-4/mac-mini-m6-16/) instead (11.2 GB at Q4). It is a different model, not a drop-in, but it does fit this machine.
* Q8\_0 needs 19.0 GB and does not fit here. The [Radeon RX 7900 XT](https://whatcanirunai.vercel.app/hardware/rx-7900-xt/) has 20.0 GB usable, enough for Q8.
* See the [best GPU for this model family](https://whatcanirunai.vercel.app/best-gpu-for/qwen3/) and the [Qwen3-14B model page](https://whatcanirunai.vercel.app/models/qwen3-14b/).
