I think these are persons in the training data. Today I have a conversation appers between John and Sarah. When I asked for who are they. The gpt says the are friend from the ABC School. John went to Harvard Sarah to MIT. For the full name it says John Smith and Sarah Jones. I think these are made up names. but i checked the John Smith and he is a lead developer at OpenAI. Sarah is blond with blue eyes. and like to dance. John is brown with green eyes who likes football and listening to music.
