Can MacBook Pro M2 Pro 16 GB run Gemma 4 26B-A4B?
16 GB unified · 200 GB/s memory bandwidth · Gemma 4 26B-A4B has 25.8B parameters (3.8B active per token).
Short answer
No. It doesn't fit in memory.
Needs ≈12 GB but only ≈8.5 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 12 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 Pro M2 Pro 16 GB has about 8.5 GB left, so it’s 3.3 GB short.
Ways to make it work
Close everything else
Not enough on its own: with every other app closed it’s still about 0.3 GB short.

The same chip with 32 GB handles it: Excellent.
