Can MacBook Air M3 8 GB run Qwen3 14B?

8 GB unified · 100 GB/s memory bandwidth · Qwen3 14B has 14.8B parameters.

Short answer

No. It doesn't fit in memory.

Needs ≈8.4 GB but only ≈0.5 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 8.4 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 Air M3 8 GB has about 0.5 GB left, so it’s 7.9 GB short.

Ways to make it work

  • Close everything else

    Not enough on its own: with every other app closed it’s still about 4.9 GB short.

  • Pick a smaller model from the same family

    No smaller Qwen3 model in our catalog runs well here. See the other models below.

  • Get more memory

    The same chip with 24 GB handles it: Acceptable.

  • Check your exact setup

The same applies to every workload we rate (chat, coding questions, coding in a repository, agentic coding and long documents): they all need at least as much memory as chat.
