Can Mac Studio M1 Max 32 GB run Llama 3.3 70B Instruct?
32 GB unified · 400 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 ≈25 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), Mac Studio M1 Max 32 GB has about 25 GB left, so it’s 9.1 GB short.
Ways to make it work
Close everything else
Not enough on its own: with every other app closed it’s still about 6.1 GB short.
Pick a smaller model from the same family
Get more memory
The same chip with 64 GB handles it: Acceptable.
