How we got this verdict
64 - 5 = 59GB usable (macOS and background processes reserve roughly 5 GB of unified memory).
Because Mac Studio 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.
Going up to 96GB (96GB) doesn't change the top recommendation — 31B is still the best fit, just with more headroom.
