Reminds me: Yesterday I was trying to get it to sketch Alexander's casket (the crystal one). So it generates a prompt that begins "Envision a casket that seamlessly blends Greek and Roman artistic traditions...", tries to draw it, and throws back "I was unable to generate images for your request due to content policy restrictions" and (of course) refuses to say why.
Fifteen minutes of breaking down the prompt into smaller and smaller chunks, narrows the problem down to this sentence: "Roman elements are represented through images of the empire's architectural triumphs, such as aqueducts and the Colosseum, and symbols of Roman authority like the fasces and SPQR inscriptions."
It's the word "fasces". It flat-out refuses to draw one in any context. I'm sure you can imagine why. So partly I'm annoyed because I'm being treated like a child, partly because this is a silly rule, and partly because the stupid chatbot was the one that suggested adding fasces in the first place.
