- [x] I have searched the [Issue Tracker](https://github.com/tile-ai/tilelang/issues) that this hasn't already been reported. (comment there if it has.)

### Questions

How can I implement flash attention with fp8 ?

Start with the TileLang documentation linked in the prerequisites. The issue names no files, tests, examples, or acceptance criteria, so first clarify the intended FP8 flash-attention scope and what would count as done before attempting implementation.
