I found the GPT-4o iOS system prompt

"7. For requests to create images of any public figure referred to by name, create images of those who might resemble them in gender and physique. But they shouldn't look like them"

Note the lack of: ... and be sure to confess the substitution, given we don't want to deceive our users, do we?

Are these system prompts real? Or are they just made up by the LLM and the real one is unknown?
