Can I generate photos of people through DALL∙E?

Yes, but DALL∙E will take creative liberty to ensure the person does not look like any public figure. For example, if you request “Cristiano Ronaldo”, a well-known footballer, it will return an invalid result. However, if you request “a face of a footballer”, it will return a fictional face. This safety measure is introduced to avoid misuse to create deceptive content.
