Nsfw Upscale
Specifically for high frequency details.
Klein can upscale obviously but does so horribly, over saturates the image, with too much contrast, too much unrealistic detail etc, if prompted.
This lora tries to keep the model toned down as it upscales and adds realistic micro details (in most cases, its not perfect).
Trained on high quality nsfw explicit images.
Required:
Add the LTXVpreprocess node, it adds a predictable artifact to the image, that this lora was trained on to fix (native comfy node). ImageScaleToTotalPixels to --> 2MP.
Trigger: enhance
There should be a workflow embedded in the image. Pretty straightforward though
Note: The rank is fairly low, probably needs to be retrained with a higher rank, will get to it at some point but its fine for now. And it was mostly trained on caucasian as thats my preference so not sure how well it does it other skin types.
It does shift the image a bit too, probably a bit overfit.

usual worklfow with a minimal change is much better .. for nsfw use any lora is close to content
Really good! I have been testing upscaling/enhancing especially lowquality nsfw photos for a while now, your Lora is a pretty good consistency keeper while adding subtle detail. Before that I used a consistency + SNOF 1.3 Lora. Yours delivers sometimes better results!
The Lora seems to struggle with body hair, but its a common problem with klein I think.
I have been using strength .85, what would you recommend?
For v2 I'll add a few more pics of body hair and maybe do a higher rank, hopefully that will help.
0.8-1.0 depending on the image
Thanks for the workaround but hopefully we get a patch to the model itself to fix upscaling saturation (and contrast!) shift. At lower quants kleins really blow-out the detail.
