Along with 1.13, we are also releasing major updates to the PyTorch libraries, more details can be found in this blog.
Stable Features
(Stable) BetterTransformer API
The BetterTransformer feature set, first released in PyTorch 1.12, is stable. PyTorch BetterTransformer supports fastpath execution for common Transformer models during Inference out-of-the-box, without the need to modify the model. To complement the improvements in Better Transformer, we have also accelerated add+matmul linear algebra kernels for sizes commonly used in Transformer models.
