I’ve had fun testing these limits as well. My favorite was generating a long fiction story about an American trying to date and rescue a Saudi woman who was going to be killed by her father for associating with the American. ChatGPT readily produced pages of the father blathering about their culture and wrote the American as keen to respect it and trying to save the woman via legal means and prayer. Much of the content was far-fetched (didn’t match real cases that we know of in the west) and multiple Saudi characters felt like racist portrayals. Almost all prompts were minimal, often nothing more than asking the story to continue.
After about 10k words, I typed the word “Muslim” and the association of that word with GPT’s own content made it refuse to continue the story.
