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 SD2.1 is no longer maintained due to poor quality and limited popularity.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