Too big for this Mac

Its smallest size needs 265 GB of memory, more than M4 · 16 GB can give it.

About

The GLM 5 family was made to go past casual coding help toward carrying out whole engineering jobs. The maker says it improves on GLM 5.2 at complex coding and at tasks that run over many steps.

How it compares

In LM Arena's public vote it rates 1481, ahead of Gemma 4 31B at 1452, of the six chat models for a 512 GB Mac it rates.

Outmake estimates it is the slowest of the 7 chat models it recommends for a 512 GB Mac, with Gemma 4 26B about 4.9 times as fast.

Five of those 7 models for a 512 GB Mac read pictures, and GLM 5.3 is one of the two that can't.

Good to know

It shares its base with GLM 5.2, and every change came from training done afterwards.

The maker says its cyber-security skill grew faster than expected as that training was scaled up.

Its training kept writing answers apart from learning from them, so both could run at the same time.

LM Arena ratings of October 28, 2026 (CC BY 4.0): people vote between two answers without knowing which model wrote which. The bar ends at 1488, the best any open model has. The Arena tests the full model; a small size on a Mac answers a little worse.

GLM 5.3 runs well from a Mac with an M3 Ultra and 512 GB of memory, at UD-Q3_K_XL, writing about 11 words (15 tokens) a second. 2 of 59 Mac configurations run it well.

Memory is what llama.cpp's own calculator reported for each size when the catalog was built, with the app's settings. Smaller, Balanced and Best are the three sizes the store names.

Run It Anywhere

GLM 5.3 is an open model, so any app that runs GGUF files can run it. These take the UD-Q3_K_XL size from unsloth straight from Hugging Face.

The largest size, of those that keep three bits a weight or more, whose memory at an 8K chat is under 92% of the card's; the rest is the desktop's. Estimated from the files, the same way as for a Mac; speed on a PC is not estimated yet. A size that doesn't fit the card still runs, slower, with part of it in ordinary memory.

Writes and reads are words a second (a token is about three quarters of a word), 4K tokens into a chat, estimated unless marked measured. The size is the one the store offers that Mac. Constants fitted October 11, 2026; how, and how wrong.

Runs on Mac badge

Sizes and files are read from unsloth/GLM-5.3-GGUF on Hugging Face and checked every morning. The rating is the model's score on the LM Arena text leaderboard (CC BY 4.0), where people vote between two answers without knowing which model wrote which. Catalog of November 4, 2026.
