M4 with 32 GB: which local LLMs run?

With 32 GB of unified memory, the M4 gives the GPU about 21.3 GB by default (120 GB/s): enough for models up to about Qwen3 32B.

Unified memory is not VRAM: macOS reserves part of it. The limit can be raised with sudo sysctl iogpu.wired_limit_mb=…, at the cost of memory for apps. There is no offload to system RAM — it is the same memory.
