7B is the realistic daily range

Capacity estimate: up to roughly 7B comfortably, 13B tightly. Context, quantization, and running apps change real-world fit.

Capacity edge
13B

13B is a capacity edge, not a blanket promise: it generally requires strong weight quantization, a short context, and little parallel load. KV-cache precision and the model architecture can materially change the result.

16GB explained Why unified memory is more than model weights Understand quantization, KV cache, macOS headroom, and the difference between “fits” and “runs well.” Open RAM guide
