Description
🚀 The feature, motivation and pitch
Currently NVFP4 is only available for SM10X in trtllm-gen. It would be useful to have this feature available for consumer Blackwell chips that are SM120 based. The primary use is to allow more VRAM to be used for context.
Alternatives
There are no alternative solutions. I tried loading the cubins for SM100 on the SM120 but it did not work.
