Flux 2 Klein 9b - Simple Workflow (NSFW)

This is a very straight-forward and simple workflow that I use often for NSFW generations with the Flux 2 Klein 9b (Fp8 scaled version).

• The workflow employs two separate image inputs for character replacement/editing.

Simple prompts work like the following:

- "The female from image1 replaces the female inside image2"

- "The female from image1 is wearing the outfit from image2"

• You can also disconnect the 2nd image input from the Positive Prompt Text Encoder, to only work with a singular image input.

My generations are often run at 10 steps, use a combination of Euler - Simple, Denoise between .75 -1 depending on how far I'm straying from my original reference (high value for bigger changes), and CFG at 1 (negative prompt disabled because of this).

Here is a list of models that I use with this workflow:
