I have created a normal one, and also an importance-aware MXFP4_MOE quantization that dynamically allocates precision based on tensor importance scores from an imatrix I created with
code_tiny.
This is a coding optimized quantization and is slightly larger than the mainline MXFP4_MOE, and the way it works is that it keeps a better quantization depending on the importance of each tensor.
As I've mentioned it is experimental, and still not have done any benchmark on it, to see if it's any better than mainline, but you are freely to try it out and report back!
