I concentrate on Tensor.art because it is easy to use and has bountiful resources and no NSFW restrictions. You can achieve some beautiful results with Tensor.art, and I do love beautiful things.
I freely admit that it isn’t so good for torture. There aren’t a lot of sites that are. Pixai.art had some good loras, but then it went non-NSFW. You can still access them if you log in through Discord, but then they only work with the anime style.
If you wanted good torture art, you could do something on Pixai.art and then clean it up with Tensor.art Img2Img. (The one on the left is Pixai, and the one on the right has been cleaned up in Tensor.) Of course, you would be paying for both sites, but if you have any experience with Tensor, doing things in Pixai wouldn’t be too hard.
I am only talking about basic procedures here, because that is where everyone starts, and if you have any tips or advice on advanced techniques, feel free to share it. I am still quite far from being an expert.
That's why I recommended Pony Diffusion. I usually try not to talk too much about AI workflows outside
the main AI discussion thread because I believe there's no right or wrong way in artistic creation.
Also, I know many, if not most, people don't get past the stage of writing random things in the prompt and hope for the best. It is not the best way to create good kinky images, but I also understand not everyone is willing to spend time learning advanced AI tools or searching for sites that provide them.
But I felt Pony Diffusion is something you should try if you rely heavily on prompting but still strive to control the output. I briefly tried generating some torture scenes in Tensor.art now, and these were what I could generate by prompting alone without using any Lora:
All you have to do is select a Pony variant model and write the prompt using tags you find on the Danbooru site. For reference, the prompt I used to generate the above images is as below:
Positive:
source_real, score_9, score_8_up, score_7_up, BREAK, 1girl, torture, naked, collar, chained, arms_behind_back, whip_marks, highly detailed
Negative:
score_1, score_2, score_3, from_behind
And that's about it. No controlnet, no Lora, and no additional img2img runs.
I only briefly checked the site, but it looks like Tensor.art isn't a bad option for those who want a free AI generator. They even offer things like control nets and some inpainting features, which are absolutely needed to create anything more serious with AI.
But it can be enjoyable enough to generate simple kinky images like that randomly. For that purpose, I think Pony Diffusion could be the best option to achieve better images without having to learn more advanced tools or spending much time and credits to get something decent out of a sea of bad or irrelevant random images.
