Comfyui now supports native stable cascade, so the diffusers sampler from v1 is no longer needed. The workflow generates images with sd cascade and improves face details if needed with an sd1.5 model.

The following resolutions work well: 1024x1024 / 1024x1904 / 1024x3808. If you know any other resolutions that work well, please post them here.

I've included a short guide on where to download the models and which folders to copy them into in the red notes of the workflow.
