Written by Jakub Rusinowski · Last updated September 29, 2026

With 128 GB at 546 GB/s, the M4 Max runs 130 catalogued models at Q4_K_M with 8K context. The largest that fits is Devstral-2 123B (~75.1 GB), and the top pick is Qwen 3.5 122B-A10B at 20–41 tok/s.

Up to 128 GB unified memory, about 96 GB usable by a model: 70B-class models at Q4_K_M fit with room for context. 35W TDP is extraordinary. Silent and power-efficient. Best all-around for Mac users.
