# beezu/GLM-4.5-Iceblink-v3-106B-A12B-mlx-mxfp4

This model [beezu/GLM-4.5-Iceblink-v3-106B-A12B-mlx-mxfp4](https://huggingface.co/beezu/GLM-4.5-Iceblink-v3-106B-A12B-mlx-mxfp4) was
converted to MLX format from [zerofata/GLM-4.5-Iceblink-v3-106B-A12B](https://huggingface.co/zerofata/GLM-4.5-Iceblink-v3-106B-A12B)
using mlx-lm version **0.31.2**.

# About this quant

Just a normal mxfp4. Before the latest version, this model used a bf16 `lm_head` layer, but that has been replaced with a full mxfp4 across the board.

There are issues with doing any sort of hybrid quantization using mxfp4/mxfp8/nvfp4, and the patches I previously put in were good enough to create a model, but not good enough to run them properly. Big thanks to @circadesu for bringing these issues to my attention.

For now, I've removed the bf16 head layer and fallen back to a "normal" quant for both mxfp4 and nvfp4. I'm also deleting the mxfp4-mxfp8 and nvfp4-mxfp8 quants of this model entirely. I want to revisit this, but it will take substantial work that I'm not ready to take on quite yet.

      <p>Then I tried out an idea I saw from <a href="https://huggingface.co/ConicCat">ConicCat</a> and trained the model for 8 epochs on 96 short stories (150k tokens) from light novels and human authors the internet said were good. This seems to have had a surprisingly positive effect on the prose without hurting the intelligence too much.</p>
      <p>I went back to my usual higher LR's for this model. It turns out the GLM chat template was more cursed than I originally gave it credit for while training. It was a skill issue all along, go figure.</p>
