> [!CAUTION]
> Starting from September 13, 2026, we will be removing the "model" type repositories of kernels (e.g., kernels-community/flash-attn3). Make sure you're using a latest version of kernels. If you face any disruption, please report them here: https://github.com/huggingface/kernels/issues/new.

This is the repository card of kernels-community/aiter-flash-attn that has been pushed on the Hub. It was built to be used with the [`kernels` library](https://github.com/huggingface/kernels). This card was automatically generated.

## How to use

```python
# make sure `kernels` is installed: `pip install -U kernels`
from kernels import get_kernel

kernel_module = get_kernel("kernels-community/aiter-flash-attn")
__kernel_metadata__ = kernel_module.__kernel_metadata__

__kernel_metadata__(...)
```

## Available functions
- `__kernel_metadata__`
- `flash_attn_func`
- `flash_attn_varlen_func`
- `flash_attn_with_kvcache`
- `mha_set_impl`
- `mha_set_use_fused_bwd_kernel`
