This repository contains some custom quants of GLM-4.5 that focus on a couple of different schemas compared to the usual quantization schemas.

The idea being that given the huge size of the FFN tensors compared to the rest of the tensors in the model, it should be possible to achieve a better quality while keeping the overall size of the entire model smaller compared to a similar naive quantization.

The following charts showcase a very wide variety of GLM-4.5 quants that were tested for KL Divergence using the reference logits and corpus included in this repo: GLM-4.5-KLD-8192-ref-logits-ed-combined-all-micro-Q8_0.bin and combined_all_micro.txt

A full CSV with the data is included as well in glm-4.5-quantization-output.csv.

The naming convention is (inconsistently) as follows, generally: [Default Type]-[FFN_UP]-[FFN_GATE]-[FFN_DOWN], eg: Q6_K-IQ2_S-IQ2_S-IQ3_S. This means:

Q6_K is the default type (attention, shared expert, etc.)
IQ2_S was used for the FFN_UP and FFN_GATE conditional expert tensors
IQ3_S was used for the FFN_DOWN conditional expert tensors

Generally speaking, quants following the above convention tend to have a better KLD and PPL compared to quants from other providers. Visualized here are the Mean KLD and Mean PPL of the quants on the Pareto frontier (so, best for a given size). Full graphs are available in the plots-glm-4.5-8192 folder.

Provided here are a few quants, separated into llama.cpp and ik_llama.cpp folders for convenience (though, ik_llama.cpp is capable of running the quants in llama.cpp, but the opposite is not true).

`llama.cpp` imatrix Quantizations of zai-org/GLM-4.5

This quant collection can be run on llama.cpp or kobold.cpp like normal.

Q6_K-IQ2_S-IQ2_S-IQ3_S: 128.18 GiB (3.07 BPW), Final estimate: PPL = 4.786993 ± 0.031213, KLD = 0.145117 ± 0.002232

GLM-4.5-Q6_K-Q2_K-Q2_K-Q3_K: 129.57 GiB (3.11 BPW), Final estimate: PPL = 4.700384 ± 0.030202, KLD = 0.164863 ± 0.002339

GLM-4.5-Q8_0-IQ3_XXS-IQ3_XXS-IQ3_S: 144.68 GiB (3.47 BPW), Final estimate: PPL = 4.729934 ± 0.030769, KLD = 0.116520 ± 0.002072

`ik_llama.cpp` imatrix Quantizations of zai-org/GLM-4.5

This quant collection REQUIRES ik_llama.cpp fork to support the ik's latest SOTA quants and optimizations! Do not download these big files and expect them to run on mainline vanilla llama.cpp, ollama, LM Studio, KoboldCpp, etc!

NOTE ik_llama.cpp can also run your existing GGUFs from bartowski, unsloth, mradermacher, etc if you want to try it out before downloading my quants.

Some of ik's new quants are supported with Nexesenex/croco.cpp fork of KoboldCPP with Windows builds for CUDA 12.9. Also check for Windows builds by Thireus here. which have been CUDA 12.8.

See Ubergarm's GLM-4.5 quants for info on how to use the recipe or make your own quant.
