Local Dream 
Android Stable Diffusion with Snapdragon NPU acceleration
Also supports CPU/GPU inference
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 SD2.1 is no longer maintained due to poor quality and limited popularity.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.
