Qwen image 2.1 struggles with generating NSFW content; at the time this workflow was created, there were no truly decent LoRAs available for this purpose. The model has particular trouble rendering the vaginal area, and this workflow was designed specifically to address that. It employs a dual-sampler setup: the first creates a high-quality base that adheres strictly to the prompt while filtering out low-probability outputs, while the second uses the resulting noise to beautifully render the rest and add fine details. When combined with the right LoRAs, this yields fairly stable NSFW generations—though the occasional anatomical mishap can still occur. I also added a touch of grain and DLSS 5 at the output stage for realism and, well, just because I could, lol.

Qwen image 2.1 super-duper stable NSFW workflow

1) Significantly improved pussy rendering quality; the new LoRA is absolutely amazing.2) I also switched to a different model checkpoint; on average, it produces more interesting images with slightly lower weight requirements. However, if you stick with the old one, you’ll still get consistently good results using the checkpoints included in this workflow version.3) Added Detailer nodes for better rendering of the face, breasts, pussy, and penis.4) I delved into sampler mechanics and added APG and FreSca settings; they provide better stability and image quality for T2I generation (though they completely break Edit mode—lol—so I’ll need to find separate settings for that).5) Tweaked the DLSS5 node settings; it no longer distorts colors heavily but instead slightly enhances the image's color palette.
