 If we would have just run the base model on the same 40 steps, the image would have been arguably less detailed (e.g. the lion eyes and nose):

 <Tip>
 
 The ensemble-of-experts method works well on all available schedulers!

+#### 2.) Refining the image output from fully denoised base image
 
 In standard [`StableDiffusionImg2ImgPipeline`]-fashion, the fully-denoised image generated of the base model 
 can be further improved using the [refiner checkpoint](huggingface.co/stabilityai/stable-diffusion-xl-refiner-0.9).
