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

Sweet spot for local LLMs. 48 GB is comfortable for 30B in 4-bit, 70B is tight.
