FYI: black images are not just from the safety checker.
Yes, the safety checker will zero out images but can just turn it off with an “if False:”; Mostly black images are due to a bug, especially frustrating because it turns up on high step counts and means you’ve wasted time running it.
My experience has been roughly 2-4/32 of an image batch comes back black at the default settings, regardless of the prompt.
Just stamp out images in batches and discard the black ones.
