 ## PyTorch with DirectML
 
-DirectML acceleration for Pytorch 1.13.0 is currently available for Public Preview. PyTorch with DirectML enables training and inference of complex machine learning models on a wide range of DirectX 12-compatible hardware. New in Pytorch version 1.13.0, pytorch-directml is now built as a separate plugin to the Pytorch library. DirectML acceleration for Pytorch 1.8.0 is still available but is now deprecated.
