🚀 The feature, motivation and pitch

hi @powderluv @chunfangamd @andyluo7

AMD only have MXFP4 checkpoints of MiniMax M2.1 but doesnt have MXFP4 checkpoints of the latest MiniMax M2.5 model

MiniMax M2.5 is the same architecture as MiniMax M2.1 but different weights. It would be great to have an MXFP4 ckpt of MiniMax M2.5 since M2.5 is way more popularity used than M2.1

We see great performance boost from MXFP4 compared to FP8 on the MiniMax architecture

Alternatives

use fp8 and get worse perf
