Hope you enjoy it! If you like it, please consider [sponsor](#-support-this-project) 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 SD2.1 is no longer maintained due to poor quality and limited popularity.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](https://t.me/local_dream) for discussion or help with testing. ## User Guide For certain reasons, all guides and documentation have been moved to [Guide Site](https://ld-guide.chino.icu). ## Credits & Acknowledgments Local Dream is built on top of many excellent open-source projects.
