 In addition to GEMM, we provide a variety of examples to showcase the versatility and power of TileLang, including:
 
-- [Dequantize GEMM](./examples/dequantize_gemm/): Achieve high-performance dequantization by **fine-grained control over per-thread operations**, with many features now adopted as default behaviors in [BitBLAS](https://github.com/microsoft/BitBLAS), which utilzing magic layout transformation and intrins to accelerate dequantize gemm.

 - [FlashAttention](./examples/flash_attention/): Enable cross-operator fusion with simple and intuitive syntax, and we also provide an example of auto tuning.
 - [LinearAttention](./examples/linear_attention/): Examples include RetNet and Mamba implementations.
 - [Convolution](./examples/convolution/): Implementations of Convolution with IM2Col.
