Can MacBook Air M3 8 GB run Llama 3.2 3B Instruct?
8 GB unified · 100 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 M3 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 30–40 tok/s. Expect the system to feel tight while it’s loaded.
