MistoLine is an SDXL-ControlNet model that accepts any type of line art as input to guide image generation. It eliminates the need to switch between different ControlNet models for different line preprocessors by exhibiting strong generalization across diverse line art conditions. The model is trained on Stable Diffusion XL’s UNet architecture and generates images with a short side greater than 1024px using a novel line preprocessing algorithm called Anyline.
