    [STOP! Give GGUF a try! You'll LOVE it!!! (more below)]

    A merge of FluxUnchained and FastFlux. As a result, it can now generate artistic NSFW images in 4-8 steps.

    You can also combine it with other LoRAs to get the effect you want.

    Which model should I download?

    GGUF is the Future

    TRY THE GGUF version at https://civarchive.com/models/662112 . It is faster, better, and more convenient.

    • GGUF Q8_0 is a more precise format than fp8 and also runs faster (at least on my 1080ti)

    • You really shouldn't be using a flat safetensor that includes T5 if you can. Every new checkpoint adds a new copy of T5 (additional 10GB/5GB) that you don't really need.

    That being said, some UI/softwares still don't support GGUF / separate files. That is why I uploaded these safetensors. But I feel guilty contributing to this anti-pattern.

    Description

    UNet only. You'll need separate T5xxl, CLIP, and VAE files (recommended for saving space). See https://github.com/lllyasviel/stable-diffusion-webui-forge/discussions/1050 to learn more about Forge UI GGUF support and also where to download the VAE, clip_l and t5xxl models.
