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 <a target="_blank" rel="ugc" href="https://huggingface.co/stabilityai/stable-cascade">here</a> and <a target="_blank" rel="ugc" href="https://huggingface.co/stabilityai/stable-cascade">here</a>) to get straight to the important things like:Which files do i need? As explained more in detail <a target="_blank" rel="ugc" href="https://github.com/Stability-AI/StableCascade/tree/master/models">here</a> 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 <a target="_blank" rel="ugc" href="https://huggingface.co/KBlueLeaf/Stable-Cascade-FP16-fixed">HF</a>.How do i use these with ComfyUI? You can already find a few workflows on civitai (-&gt;Suggested Resources) and the main developer of ComfyUI has provided a starter workflow <a target="_blank" rel="ugc" href="https://gist.github.com/comfyanonymous/0f09119a342d0dd825bb2d99d19b781c">here</a>. 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 <a target="_blank" rel="ugc" href="https://github.com/blue-pen5805/sdweb-easy-stablecascade-diffusers">extension</a> 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.

<h1 id="heading-2">NOTE! YOU MUST DOWNLOAD BOTH MODEL FILES!!!</h1>This is just a convenience bundling of the official StableSwarmUI models for Cascade, since the SAI folks dont seem to want to have a direct presence on CivitAIThe official writeup is at <a target="_blank" rel="ugc" href="https://github.com/Stability-AI/StableSwarmUI/blob/master/docs/Model%20Support.md">https://github.com/Stability-AI/StableSwarmUI/blob/master/docs/Model%20Support.md</a>"You must keep [these two models] in the same folder, named the same with the only difference being <code>stage_b</code> vs <code>stage_c</code> in the filename.Either model can be selected in the UI to use them, it will automatically use both."All copyright for these, is as per the official SAI Stable Cascade license(s)<h2 id="heading-20">Yes, These will run on 8GB VRAM! </h2>(they are the bf16 models, apparently)Yes, I know the one file is 9GB in size, but thats because , like other checkpoints, it actually includes multiple model pieces in the same file.Just make sure to download both.I personally make a "Cascade" subfolder and put them in there.
