How to Download & Install Fluxed Up

- Download the
.safetensors(or.gguf) file. - Place it in
models/Stable-diffusion(Forge) ormodels/checkpoints(ComfyUI). - VAE & CLIP: Fluxed Up does not bake these in. Use Flux VAE and T5-XXL CLIP — Forge/ComfyUI usually load these automatically if you have base Flux installed.

Fluxed Up vs CHROMA vs Other Flux NSFW Options
Fluxed Up — Specialized checkpoint. Female-primary, nude-focused. Strong NSFW bias out of the box. Single checkpoint, no LoRA stacking needed for the core use case.
CHROMA — General uncensored Flux fork. More versatile — photorealistic, various subjects. Use LoRAs for specific styles. Better if you want flexibility beyond one niche.
Base Flux dev/schnell — Lightly censored. Can be pushed with LoRAs but inconsistent. Not recommended for NSFW.
Bottom line: Want a dedicated nude/NSFW Flux model? Fluxed Up. Want a general uncensored Flux base? CHROMA.
Bottom Line
Fluxed Up 7.1_FP16 is a solid Flux NSFW checkpoint for female-primary nude content. Download from CivitAI, drop into Forge or ComfyUI, use DPM++ 2M + beta scheduler. Ensure VAE and CLIP are set. Non-commercial only.
