## Credits

`flash_attn` wheels are mirrored from [mjun0812/flash-attention-prebuild-wheels](https://github.com/mjun0812/flash-attention-prebuild-wheels) — all credit for those builds goes to the upstream author. We mirror them here so the install scripts have a single source of truth and do not break if upstream release URLs change.

The remaining wheels (`ace_step`, `block_sparse_attn`, `q8_kernels`) were built in-house.
