How we got this verdict
24 - 5 = 19GB usable (macOS and background processes reserve roughly 5 GB of unified memory).
Because Mac Mini has enough unified memory to spare, 12B 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.
Going up to 32GB (32GB) unlocks 31B at Q4_0 (4-bit) — a step up from 12B here.
