As with any of these models, use Euler or Euler A samplers. Comfy user should use ModelSamplingDiscrete and set it to v-prediction. I'll add more info here as I continue to research but for now, resources.
You can find CSV files filled with tags the model understands . Both danbooru and e621. Which... just means prompting like you would an Illustrious model.
ComfyUI users can use the example workflow . Just drag the image into comfy to open the workflow.
