MultiDiffusion Panorama allows to generate high-quality images at arbitrary aspect ratios (e.g., panoramas).  Fine-tuning your own models In addition to pre-trained models, Diffusers has training scripts for fine-tuning models on user-provided data.  DreamBooth Project DreamBooth fine-tunes a model to teach it about a new subject. I.e. a few pictures of a person can be used to generate images of that person in different styles.  Textual Inversion Paper Textual Inversion fine-tunes a model to teach it about a new concept. I.e. a few pictures of a style of artwork can be used to generate images in that style.  ControlNet Paper ControlNet is an auxiliary network which adds an extra condition.
