n=1 but I find I'm consistently censored trying to generate images of people, but drawings, animals and objects are generally fine so perhaps that's the difference.
Try "a super hero asleep on the couch, under a blanket" in dalle-3 and see what you get, I get zilch no matter how many times I run it, this is clearly unsafe content apparently.
I've found the AI generally more forgiving on anything "art". This lets you get away with things like a nip slip on a statue or provocative situations in a painting for instance. The second you try and make it in a "realistic" setting though, you get the dog or worse.
