Can MacBook Air M2 24 GB run Llama 3.3 70B Instruct?

24 GB unified · 100 GB/s memory bandwidth · Llama 3.3 70B Instruct has 70.6B parameters.

Short answer

No. It doesn't fit in memory.

Needs ≈34 GB but only ≈17 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 34 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 M2 24 GB has about 17 GB left, so it’s 17 GB short.

Ways to make it work

  • Close everything else

    Not enough on its own: with every other app closed it’s still about 14 GB short.

  • Pick a smaller model from the same family

  • Get more memory

    You’d want at least 41 GB of memory in total. The machines below are the cheapest that run it comfortably.
