What practitioners keep saying
Apple Silicon field sources
Spicyneuron Hugging Face model cards
A GLM-5.1 MLX 2.906 bpw community quantization card reports M3 Ultra 512GB benchmark methodology and memory, adding a second direct MLX reproduction target for extreme-memory Apple Silicon.
Spicyneuron Hugging Face model cards
A GLM-5.1 MLX 3.645 bpw quality-first community quantization card reports M3 Ultra 512GB benchmark methodology, adding a higher-memory reproduction target beside the existing 2.9-bit compact card.
A LocalLLaMA M3 Ultra Mac Studio thread reports GLM-5.1 Q4 running on high-memory Apple Silicon, with a commenter giving only rough context-dependent throughput and warning that prompt processing is the weak point.
An MLX issue shows that distributed GLM-5.1-MXFP4-Q8 throughput depends heavily on benchmark setup: an initial two-node M3 Ultra report was extremely slow, while an MLX maintainer later pointed to the proper distributed benchmark path and closed the issue as not a kernel bug.
Avlp12 Hugging Face model cards
A GLM-5.1 MLX dynamic-quantization card reports M3 Ultra 512GB throughput and memory, giving Silicon Score a concrete Apple Silicon reproduction target with lower memory than uniform 4-bit claims.

Runtime/source notes to verify
Zai Org Hugging Face model cards
The official GLM-5.1 model card says open-source local-serving frameworks support the model, but it does not establish that GLM-5.1 is practical on Apple Silicon.

What would improve confidence
Current published coverage
This page stays published because the model is in the current frontier catalog, but Apple Silicon speed coverage is still missing.
Rows stay below the ranking because this page is answer-first. Use them to inspect exact chips, quantizations, runtimes, and sources.
No benchmark rows are published yet for this model. The ranking above still shows the best current Mac fit path, but the benchmark section stays empty until direct Apple Silicon measurements land.
