Apple M4 16GB for local AI
The base Mac mini and MacBook. macOS lets the GPU use about two thirds of 16 GB by default, so plan for about 10.7 GB. Good for 7B to 8B models at modest speed.
Among the 2 devices we track with about 11 GB of usable memory, the Apple M4 16GB is the slowest at generating text, because generation speed follows memory bandwidth. Others in the same class: RTX 2080 Ti 11GB. They all hold the same models; the faster ones simply answer sooner.
Our picks for the Apple M4 16GB
The model we would run first for each job, chosen from our recommendations by what fits fully with an 8K context. "Best quant" is the highest quality that fits; "max context" is at Q4_K_M or the native format.

Apple M4 16GB for LLMs: common questions
Can the Apple M4 16GB run Llama 3.3 70B?
No. It needs about 43.2 GB at Q4_K_M, far more than the 10.7 GB available.
Can the Apple M4 16GB run Qwen 3 32B?
No. It needs about 21.4 GB at Q4_K_M, far more than the 10.7 GB available.
Can the Apple M4 16GB run Qwen 3 14B?
Yes. Qwen 3 14B needs about 10.5 GB at Q4_K_M with 8K context, and the best quality that fits is IQ4_XS.
How fast is the Apple M4 16GB for LLMs?
About 14 tokens per second for an 8B model at Q4_K_M, based on its 120 GB/s memory bandwidth. Larger models scale down roughly in proportion to their size.
How much of the 16 GB can the GPU use?
About 10.7 GB by default. You can raise it with sudo sysctl iogpu.wired_limit_mb=<MB> (resets on reboot), leaving at least 8 GB for macOS.
