Local AI fit

35B is the realistic daily range

Capacity estimate: up to roughly 35B comfortably, 70B tightly. Context, quantization, and running apps change real-world fit.

Comfortable: 35B
Tight: 70B
Capacity edge: 70B

70B 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.

64GB 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
