Pre May 2025, i guess they use SD, this is the time where we can use (example:1.3) in prompt and use negative prompt, lot of character recognized whether it fictional or real.
Post May 2025, they say they use Flux, no more (example:1.3) or negative really being accounted to generation, but i still like it since it generate great oil painting or painting in general, still high prompt2image accuracy, prompt still recognize painter name style, like greg rutkowski or alexi zaitsev. me personally like this version much…
Post August 2025, thing gone ashtray, lot of generation artifacts or simply generating random stuff, gradually fixed and improved till now (that what they said), but imo never reach the peak pre august 2025.
Btw, i kinda like this recent one, it’s improved if you generate painting style image.
now, here what i understand within my grasp about perchance, i’m not an ai expert or coder or programmer, just your yet another regular user.
those generator (all really) are simply just a “front end” to serve you to use real perchance generator, some are simple and some more advanced with fancy setting, all can have their own names. You can create one of this “front end” and name it “SD generator” or “SDXL generation” for yourself but in the end they use the same current model that being used by the server.
All of those advanced fancy setting are just adding extra prompt words to the generator without you knowing it, you can check it by generating an image with only one prompt words, after images generated, click the “i” on the top left corner of the images to see what prompt being added by using those fancy setting.
so no matter who generator you using now, they are still using same model, for this reason, you will never achieve the same image result.
again, i’m not an expert, just user, take this info with grain of salt.
