StableFace is an open-source project based on Stable Diffusion 2.1 that aims to help users understand key aspects of Stable Diffusion, such as sampling, architecture, CFG, attention layers, reverse scheduling, keypoint inversion, image reconstruction, and prompt2prompt editing through a series of simple Jupyter Notebook tutorials. This enables the achievement of surreal facial editing effects. The project is suitable for developers and researchers interested in generative AI and facial image editing.
