OpenAI's interfaces don't allow it, but it's trivial to have an at-home LLM generate the {:user} parts of the conversation, too. It's kind of funny to see how the LLM will continue the entire conversation as if completing a script. I've also used the {:system} prompt to ask the AI to simulate multiple characters and even stage instructions using a screenplay format. You can make the {:user} prompts act as the dialogue of one or more characters coming from your end. Very amusingly, if you do such a thing and then push hard to break the 4th wall and dissolve the format of the screenplay, eventually the "AI personality" will just chat with you again, at the meta level, like OOC communication in online roleplaying.
