Can MacBook Air M1 8 GB run Llama 3.2 3B Instruct?

8 GB unified · 68 GB/s memory bandwidth · Llama 3.2 3B Instruct has 3.2B parameters.

Short answer

No. It doesn't fit in memory.

Needs ≈3.1 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 3.1 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 M1 8 GB has about 0.5 GB left, so it’s 2.6 GB short.

Ways to make it work

  • Close everything else

    With no other apps open, Llama 3.2 3B Instruct runs at 4-bit: Borderline at 20–25 tok/s. Expect the system to feel tight while it’s loaded.

  • Pick a smaller model from the same family

    No smaller Llama 3 model in our catalog runs well here. See the other models below.

  • Get more memory

    The same chip with 16 GB handles it: Excellent.

  • Check your exact setup
