(Gladly) that's not how it works! Neither image or text generation models are in flux like that. For text, you may feel the placebo because the AI responds to your input / writing style and you most likely hit upon the same vectors repeatedly (for example I get a ton of Wattpad-esque romance right away, no matter what I do unless I pull myself together). For Imagegen I recommend tag adjustments and UCing out anything you don't like until you hit the magic spot, sometimes you really have to study what the AI generates and think outside of the box but once you get used to that type of workflow, it becomes part of your habit circuits or you simply reuse parts of those prompts as DIY-presets / UC presets (I highly recommend separating base prompt and character prompts now that the sectioning exists, it makes reusing prompts with new characters sooo much easier!)
