Hi Civitains! I hope someone more savvy can help me understand a few basics about SD. My core question is: SD is an artificial intelligence machine learning program, right? So where does the machine learning happen? I use a local install mostly, because I like control and hate queues. So is my local install learning from my usage, and will learn my "style"? Is the CivitAI service then always going to be better for general tasks because it learns much more? Or does all the ML happen pre-release, and that's why we need so many loras etc.?
Moving along, as a purely practical matter, what does SD 1.5 do best and worst? What do you use it for and what would you never use it for?
I have an opinion for the "never" list: Anything involving men. Like seemingly most here, I like to make a title image when I post, as seen above. Here's the prompt I used:
masterpiece high-quality photo
English man, dark hair, green eyes looking straight forward at camera with a quizzical, confused, frowning look on his face (scratching his head with his right hand, left hand out of frame:1.2), in a futuristic computer center
cinematic lighting
I understand my prompting sucks, but seriously, I didn't think I'd have to fight for this one. This is a stock photo cliche; I could've found a dozen usable versions online in the time it took to get this ridiculously bad version. And it's the best one! Kinda. Let's look at the grid:
Oh, the lolz. 3 hands, 6 fingers, baby fingers, alien hands, almost total disregard for the prompt. And this isn't gen 1, more like 20. 5 tries or so just to get him to look at the camera. Do I have to use ControlNet for -everything-? Yes, I tried different base models. Yes, I used a negative prompt. Yes, I tried ADetailer, gave up, it gave him radioactive eyes, Botox injections, and ignored the hand issues every time. I understand that I don't know how to use it well but again, I didn't think this was going to be a fight. I mean, I'm pretty sure that if I input something like "waifu Kutie Kawaii doing naked cartwheels" I'm going to get amazing boobs from g1 and be well on track if not done in a few gens. I just don't think there's enough men in the model to follow simple prompts like "right hand scratch head". Or is it just me, the prompt's -that- bad?
Well enough ranting, thanks for reading, your advice, comments, and good-natured insults are welcome.
