SDXL moves from a base resolution of 512x512 to 1024x1024 along with better prompt recognition, so your prompting will likely need to evolve. However, there is a new type of SDXL model, ‘lightning’ that generates images in 2-8 iterations as opposed to 16-60. Prompts are also different for these types of models. I suggest the SDXL Lightning version of Juggernaut. The only time you might be interested in going back to older models would be compatibility with Loras or animation modules.
Note that on lightning models you’ll need to lower your CFG Scale to around 1.5 - 2.5
You’re most welcome!
