Stable Cascade by Stability.AI (single files)

This is a single file download alternative to the exisiting upload here on civitai. I'll skip the technical mumbo-jumbo (you can read about that here and here) to get straight to the important things like:

Which files do i need? As explained more in detail here you basically need the Stage A model, the EfficientNet encoder model, the Previewer and any combination of the available Stage B and C models. Both are available in large and lite variants (due to site restrictions labeled full and pruned in this case, the file names are the original ones, though), so test and choose what works best on your hardware. The FP16 fixed models were created by KBlueLeaf on HF.

How do i use these with ComfyUI? You can already find a few workflows on civitai (->Suggested Resources) and the main developer of ComfyUI has provided a starter workflow here. You can also find the correct locations for all the different models involved there: Stage A goes into /models/vae/, Stage B and C into /models/unet/, the text encoder into /models/clip/. StabilityAI provides a Stage B and C model specifically for ComfyUI users, which i also reuploaded here, no idea, though, in what way they exactly differ.

How do i use these with Automatic1111/Forge? At the moment i only know of this extension implemention of Stable Cascade for the Automatic/Forge platform. Let's hope native support is on its way.

DISCLAIMER: As always, if you are the owner of the model and don't want to see it uploaded here, then please do reach out to us and we will find a solution.
