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.
