About this Repo
This project is now open sourced and completely free. Hope you enjoy it!
If you like it, please consider sponsor this project.
Note
Currently focused on SD1.5 and SDXL models. SD2.1 is no longer maintained due to poor quality and limited popularity.
NPU support:
- SD1.5 models are supported on Snapdragon NPUs with Hexagon V68 architecture or newer.
- SDXL models are supported on Snapdragon 8 Gen 3 and newer devices.
If your chip is outside the above scope, you can only run SD1.5 on CPU/GPU.
You can join our telegram group for discussion or help with testing.
User Guide
For certain reasons, all guides and documentation have been moved to Guide Site.
