controlnet-scribble-sdxl-1.0

General Scribble model that can generate images comparable with midjourney!

Controlnet-Scribble-Sdxl-1.0

Hello, I am very happy to announce the controlnet-scribble-sdxl-1.0 model, a very powerful controlnet that can generate high resolution images visually comparable with midjourney. The model was trained with large amount of high quality data(over 10000000 images), with carefully filtered and captioned(powerful vllm model). Besides, useful tricks are applied during the training, including date augmentation, mutiple loss and multi resolution. Note that this model can achieve higher aesthetic performance than our Controlnet-Canny-Sdxl-1.0 model, the model support any type of lines and any width of lines, the sketch can be very simple and so does the prompt. This model is more general and good at generate visual appealing images, The control ability is also strong, for example if you are unstatisfied with some local regions about the generated image, draw a more precise sketch and give a detail prompt will help a lot. Note the model also support lineart or canny lines, you can try it and will get a surpurise!!!
