   description: "TL;DR: Self-guidance is a method for controllable image generation that guides sampling using only the attention and activations of a pretrained diffusion model. Without any extra models or training, you can move or resize objects, or even replace them with items from real images, without changing the rest of the scene. You can also borrow the appearance of another image or rearrange scenes into a desired layout.",
