How we got this verdict
64 - 5 = 59GB usable (macOS and background processes reserve roughly 5 GB of unified memory).
Because Mac Mini has enough unified memory to spare, 31B fits at SFP8 (8-bit)— a higher-precision quant than most setups get. You don't need the 4-bit QAT build here, though it's still a safe download if you want a smaller file for a second model running alongside it.
Real-world notes for this configuration
64GB is toward the top of what the Pro-chip Mac Mini offers — a genuinely workstation-class memory configuration in a compact desktop that costs meaningfully less than a similarly-specced MacBook Pro or Mac Studio. At this tier, every current Gemma 4 model fits at Q4_0 with room to spare, and several fit at higher-precision quants too.
- ⚠Even with ample memory, the Mini's smaller chassis means less sustained thermal headroom under continuous heavy load than the Mac Studio at the same memory tier — a real trade-off for long, back-to-back sessions.

FAQ
Can a Mac Mini (64GB) run the 31B flagship model?
Yes, comfortably — Gemma 4 31B fits at SFP8 (8-bit) (~30.4GB), using 59GB of usable memory on this configuration.
What's the best Gemma 4 model for a Mac Mini (64GB)?
Gemma 4 31B at SFP8 (8-bit) (~30.4GB) is the best fit — it's the largest model that runs comfortably within the 59GB of usable memory here.
What if I have more or less memory than 64GB?
This is the top configuration in this family — every Gemma 4 model already fits at its best available quant. With less (e.g. 48GB), the best-fitting model gets smaller or tighter — see the Mac Mini page.
Is a 64GB Mac Mini a genuine alternative to a Mac Studio for local AI?
For raw memory capacity and cost, yes — a 64GB Mini is significantly cheaper than an equivalent Studio. The Studio's advantages at this tier are a higher memory ceiling if you want to go further, and a chassis built for more sustained heat under continuous load.
Does 64GB cover the entire current Gemma 4 lineup?
See this page's model table above — at this usable-memory tier, all five current Gemma 4 models fit, several comfortably even at higher-precision quants than Q4_0.
