What really surprises me about this is that it sounds like they're not even trying to classify and censor generated images post-generation?

Nothing is perfect, but there are tiny classifier models that can at least mark things containing nudity and gore. That would be the bare-minimum I would expect for trying to put guardrails around an image generator.

and yet as fable demonstrated in its inability to differentiate anything physics biology or chemistry related from actual safety concerns, it’s apparently not easy to do
