With the 1.4 checkpoint, everything under 40 steps can't be used basically and you only get good fidelity with >75 steps. I usually use 100, that's a good middleground.


How do you change these steps in the given script? Is it the --ddim_steps parameter? Or --n_iter? Or ... ?


With --ddim_steps


I found I got quite decent results with 15-30 steps when generating children’s book illustrations (of course, no expectation for hyperrealism there)
