Key Points

AMD Quark is presented as a tool that appears to help quantize machine learning models, according to its documentation link.
The post suggests that trained models output in MXFP4 format may offer better quality, citing a Hugging Face example (MiniMax-M2.5-MXFP4).
The author notes that only a few hundred downloads per model update may indicate the project has gone unnoticed.
The article provides links to the AMD Quark documentation and a related Hugging Face model page for further reference.
The discussion was submitted on Reddit, inviting others to share awareness about AMD Quark.

And it looks like they post train models in mxfp4 giving it better quality: https://huggingface.co/amd/MiniMax-M2.5-MXFP4

They only have a couple hundred downloads per model update so maybe its gone unnoticed?
