What this model is, and what Apple Silicon users are actually seeing

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

GLM-5.1 is our next-generation flagship model for agentic engineering, with significantly stronger coding capabilities than its predecessor.

Official takeaways

GLM-5.1 is our next-generation flagship model for agentic engineering, with significantly stronger coding capabilities than its predecessor.
But the most meaningful leap goes beyond first-pass performance.

Deployment notes

Official model card lists SGLang v0.5.10+, vLLM v0.19.0+, xLLM v0.8.0+, Transformers v0.5.3+, and KTransformers v0.5.3+ as local deployment paths.

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: 7 Apple Silicon field reports; best reported generation ~19.527 tok/s; best reported prompt processing ~194.216 tok/s; reported RAM use ~251-382.6GB; seen on Mac Studio M3 ULTRA 512GB, Mac Studio M3 ULTRA 256GB; via MLX, oMLX.

What practitioners keep saying

The card reports GLM-5.1 2.906 bpw MLX quant on a Mac Studio M3 Ultra 512GB with 194.216 tok/s prompt processing, 19.527 tok/s generation, and peak memory at 272.358GB using 1024 prompt tokens, 512 generated tokens, and 5 trials.
The Hugging Face API reports the model was created on 2026-04-08 and last modified on 2026-04-27, so use 2026-04-27 as the source date for this card snapshot.
The card is useful for quantization comparison against the 2.681 bpw Alis card, but it should not become a canonical benchmark row until reproduced or imported through a trusted methodology path with Silicon Score hygiene.

Current published coverage

This page stays published because the model is in the current frontier catalog, but Apple Silicon speed coverage is still missing.

Raw benchmark rows for GLM-5.1

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.
