+__NOTE__
+
+Active development on `stable-fast` has been paused. I am currently working on a new `torch._dynamo` based project targeting new models such as `stable-cascade`, `SD3` and `Sora` like mmodels.
+It would be faster and more flexible, as well as supporting more hardware backends rather than `CUDA`.
+
+Contact is welcomed.

 `stable-fast` achieves SOTA inference performance on __ALL__ kinds of diffuser models, even with the latest `StableVideoDiffusionPipeline`.
