How we got this verdict
36 - 5 = 31GB usable (macOS and background processes reserve roughly 5 GB of unified memory).
31B lands on Q4_0 here, so grab the official QAT (quantization-aware training) checkpoint instead of a generic Q4_0 quant. Google shipped a full-quality QAT build for 31B at essentially the same ~19GB download size, with noticeably better output quality than a naive 4-bit quant. See the QAT guide for exact file names.
Going up to 48GB (48GB) doesn't change the top recommendation — 31B is still the best fit, just with more headroom.
Real-world notes for this configuration
36GB is the entry Mac Studio configuration, built around the Max chip — unlike the MacBook Pro or Mac Mini, the Studio line doesn't offer a base or Pro-chip tier at all; every Studio starts at Max-class memory bandwidth. That makes even the cheapest Mac Studio configuration meaningfully faster for memory-bound inference than a same-capacity MacBook Pro or Mac Mini on a lower chip tier.
- ⚠The Studio's desktop chassis and active cooling mean sustained, hours-long inference sessions don't throttle the way a laptop would — a real advantage if you're running it as a dedicated local-AI box.

FAQ
Can a Mac Studio (36GB) run the 31B flagship model?
Yes, comfortably — Gemma 4 31B fits at Q4_0 (4-bit) (~17.4GB), using 31GB of usable memory on this configuration.
What's the best Gemma 4 model for a Mac Studio (36GB)?
Gemma 4 31B at Q4_0 (4-bit) (~17.4GB) is the best fit — it's the largest model that runs comfortably within the 31GB of usable memory here.
What if I have more or less memory than 36GB?
With more (e.g. 48GB), you can run larger models or the same model more comfortably — see the Mac Studio page. This is already close to the practical floor for running Gemma 4 at all.
Does the entry Mac Studio have the same chip as a base MacBook Pro?
No — every Mac Studio configuration starts at the Max chip tier, which has meaningfully higher memory bandwidth than the base or Pro-chip options available on the MacBook Pro and Mac Mini.
Is 36GB on a Studio worth it over a cheaper Mac Mini at similar memory?
The Mini's Pro chip tops out at lower memory bandwidth than the Studio's Max chip — if Max-class bandwidth specifically matters to you, the Studio is the way to get it, though the Mini is the cheaper path to the same raw capacity.
