How can I improve my image with AI?

spram

Hello,

I'm as interested in AI as I am in Daz3D, and if I can combine the two, it would be amazing. I tried this rendering of a famous Arab actress on Sora via ChatGPT, asking "Can you just improve the image?" I have to say it works well. The problem is that I can't improve an image that is morally questionable in terms of sexuality. Do you know of another free site that would allow me to do the same thing for NSFW images?
I can also use Stable Diffusion to do this, but I don't know of any models that can improve a photo without changing its style...
