DEPRECIATED!

This model was surpassed by the new MagicQuant hybrids. The collection can be found here:

https://huggingface.co/collections/magiccodingman/magic-quant

Use the new version. This shown MXFP4 hybrid is no longer viable in comparison, nor really useable. The data collected is good for understanding and research, but it's not as good for real use.

Unsloth - Qwen3 VL 32B Thinking MXFP4 Hybrid GGUF

Dense model utilizing MXFP4_MOE with hybrid weights on a dense model. Achieving interesting results that show smaller file size, more TPS, and near lossless precision.

Use one of the 3 found magic models!

Stats compared against the standard Q8_0 (precision loss still compared to F16)

• MXFP4_MOE-Q6_K

  2.9% smaller than Q8 • 22.96 TPS • 0.0112% precision loss

  What makes this special is this basically is THE Q8 for this model. The Q8_0 under performs significantly and this is the quant you'd want if you're wanting that level of precision. Though the Q6_K base is also ridiculously low precision. Honestly, unless you're a scientist, this is more a cool showcase of MXFP4, not necessarily something you'd want to sacrifice the VRAM for in my opinion.

This repository contains a set of hybrid MXFP4 quantized GGUF models designed to explore a surprising discovery:

A carefully targeted combination of MXFP4 + high-precision embeddings/output weights can deliver near-Q8 accuracy with Q4–Q6 level throughput and smaller file sizes than Q8.

Unlike pure MXFP4, which heavily degrades dense models. This hybrid method selectively protects tensors that matter most for semantic stability, while allowing MXFP4 to accelerate everything else.

This is experimental. And should be treated as such. I am more than encouraging people to use these models and leave feedback! Though precision loss seemed near lossless, did the hybrid models act strange in certain situations? Worse or better on some topics compared to the original model? Did it do better/worse overall on everything? I'd love to hear back from others!

The Magic Model

MXFP4_MOE-Q6_K

(5.2% smaller than Q8 • 264.49 TPS • 0.0992% precision loss )

Honestly, this one is hands down the best. Best TPS, lowest precision loss, this is the one you want.

The following was the conversion script:

llama-quantize \
  --tensor-type token_embd.weight=Q6_0 \
  --tensor-type output.weight=Q6_0 \
  "Path_To_F16_GGUF.gguf" \
  "Path_To_GGUF.gguf" \
  mxfp4_moe

MXFP4_MOE Hybrid Naming Scheme & Synopsis

Multiple different combinations of converted models were created. The results were interesting to say the least. The following table will explain my naming scheme to what was done to the model to create it.

The results achieved were interesting to say the least. It was a brute force game of mass creating models with hybrid methods to find combinations that didn't cause too much noise and paired well with MXFP4.

This repo showcases the converted models, whether good or bad that was created. But, I have been testing other models in different combinations as well. The winning hybrid combinations shown in this repo DOES NOT always equate to the same results on different models.

Some models do better or worse with different kinds of combinations. It depends if it's dense, MOE, and much more. Many times the results surprise me. Many models no matter the combination will not play nice with MXFP4. At least with the methods shown here.
