To the question "why not put the AI TAG"... well for the reason that as soon as people see the tag, they imagine that everything was done by AI. Most people don't know the difference between txt2img and img2img
some don't even know what these successions of letters mean
I use a max denoising of 20, it's very light, so yes, I assume not to put the tag, because I believe that my part of the work (95%) does not deserve to be placed in the same category as those who generate images in txt2img with MJ or dallE or other...
