Check out the power bank reviews from the channel "Allthingsoneplace". He does excellent reviews, pretty much exclusively focused in the technical side, testing efficiency, protections, etc. He also tests if it would work as an UPS. Most dont work and turn off after a while.
This article is about the newest model, SD3 medium (2B). Previous Models such as SD2 and SDXL were also mostly unable to generate nudity, though they managed beach or summer images. The earliest SD1.5 is most capable of nudity, especially with the copious fine tunes focused on that. SD3 though completely freaks out as soon as it starts generating skin. Its straight up weird. Only winter images with full head to toe clothing produce humans at all. Its currently a landscape generator. Even realistic animals are hard for it. Whatever it successfully generates looks quite nice though. Pretty background wallpapers.
