# 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 SD2.1 is no longer maintained due to poor quality and limited popularity.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.

CPU/GPU inference supports SD1.5 and imported SDXL MNN packages. Large SDXL models require substantially more memory than SD1.5.

You can join our telegram group for discussion or help with testing.
