Can the Mac Mini M4 run Granite 4.2 3B?

Yes. Granite 4.2 3B fits the Mac Mini M4's 16 GB at Q4_K_M (about 3.8 GB needed), running at an estimated 34 tok/s. There's room for up to FP16 if you want higher quality.

Frequently asked

Quick answers

Can the Apple Mac Mini M4 run Granite 4.2 3B?

Yes. Granite 4.2 3B fits the Mac Mini M4's 16 GB at Q4_K_M (about 3.8 GB needed), running at an estimated 34 tok/s. There's room for up to FP16 if you want higher quality.

How much VRAM does Granite 4.2 3B need?

About 2 GB of weights at Q4_K_M, 4 GB at Q8_0 and 7 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.

How fast is Granite 4.2 3B on the Mac Mini M4?

Roughly 34 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the Mac Mini M4's 120 GB/s memory bandwidth.
