Description
What is your question?
By "natively," I mean without relying on third-party implementations. If I understand correctly, FasterTransformer and TVM have already developed their own CUTLASS extensions for constructing INT4/INT8 x FLOAT16 GEMMs. Just wondering if the latest CUTLASS release can already do this now? Thanks!

Done means confirming whether native support exists or documenting the gap.
