M2 with 24 GB: which local LLMs run?

With 24 GB of unified memory, the M2 gives the GPU about 16 GB by default (100 GB/s): enough for models up to about Mistral Small 3.2 24B Instruct.

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.

For each model, the highest-precision quantization that runs entirely in fast memory; otherwise the one with the best result. Speeds are ranges; "estimate" unless a benchmark exists for this exact hardware.
