They mentioned multiple times in previous blog posts that they do not cherry pick examples.
Would you appreciate more if their model generated cats with 5 legs in 99% of cases, and they cherry picked that 1 in 100 image where it has 4 legs? Do you think doing that would make them more caring and professional?
I doubt their models are that bad for simple and common things like cats, probably takes just a handful of tries at most for something like getting the correct number of limbs. They could just mention the number of tries on the side like a little bubble showing up to show “Rendered in 5 attempts” or something along those lines. I wouldn’t think less of the tech personally.
