Start with the ranked Mac table above. Use the rest of this page to inspect raw Apple Silicon coverage and model metadata.
What this page answers best
GLM-5.1 is cataloged because Apple Silicon buyers are already searching for it. GLM-5.1: 2 practitioner claims; 2 captured from fetched artifacts; hardware mentions: M3 Ultra, Mac, Mac Studio; themes: apple_silicon_viability, coding_quality, fit_and_memory, operational_caution, runtime_tuning; includes operational caveats. Use the ranking above for the current best Mac path, then open Bench when direct evidence lands.
Evidence state: 2 practitioner signals tracked, but no published benchmark rows yet.
Catalog record
No Apple Silicon benchmark rows are published for this model yet. It is kept visible here because it is part of the current frontier catalog.
Official model cards tell you what the model is for and which software stacks it targets. Field reality below shows how much Apple Silicon evidence we have so far.
Official brief
Runtime support mentioned
Official specs
Official model cards describe intent, capabilities, and supported stacks. They do not prove Apple Silicon speed by themselves.
Field reality on Apple Silicon
GLM-5.1: 1 Apple Silicon field report; best reported generation ~25 tok/s; seen on Mac Studio M3 ULTRA 512GB.
What practitioners keep saying
Field evidence sources
A LocalLLaMA M3 Ultra Mac Studio thread reports GLM-5.1 Q4 running on high-memory Apple Silicon, with a commenter claiming roughly 25 tok/s at 4-bit and roughly 19 tok/s at higher contexts while warning that prompt processing is the weak point.
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.
Hardware mentioned in reports
What would improve confidence
Current published coverage
This page stays published because the model is in the 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.
