I wrote it twice mistakenly. I compose my prompts by copy pasting from other prompts I use or steal. I don't know how many I made but over 100 that session. I have several dozen gigabytes of SD images saved up already. My computer can make a 30 steps 512x512 image in maybe around 15-22 seconds. It takes maybe a minute to make a 768-1024 45 step image. I'm not sure of the numbers. I don't pay too much attention to that. I usually leave them generating and go do something else. I also test so many different configurations that the numbers mix up in my memory. RTX 2060 with 6gb VRAM.
Nice hobby, nice tools, much more productive (~1 000 000 x ?) than oil painting !
... so can you ask the computer to make a 768x1024 as a better version of a 512x512 (same image yet better quality) ?
yes. It doesn't really "make a better version of X", but "make a version based on X", which depending on your preferences might come out as better or completely different. But yes, in summary, if you're not picky about the meaning of words, yes, you can do that.
