Hi MiniMax team,

First, thank you for the great work on MSA and for open-sourcing it. Also thanks for contributing the original HF Kernel Hub package.

I tested and packaged a FlashRT-maintained Blackwell / GB10 extension of the MiniMax MSA decode-sparse path for the HF Kernel Hub:

This package targets NVIDIA Blackwell compute capability 12.x and has been validated on DGX Spark / GB10 / SM121. The main goal is to make the MiniMax MSA decode-sparse path usable beyond the original SM100-only target.

Source repo:

I’d be happy to keep iterating on this and gradually port more of the SM100 MSA API surface to Blackwell where it makes sense.
