Thank you for sending this. It's still quite puzzling to me if it's actually possible or not. Maybe what I want to train is a style? But then again, it should also remember other important things related to the friend..
Parent comment is on the right track. It sounds like you want to fine tune an llm to mimic the conversation style between you and your friend. Then you can use a general embedding model to implement RAG so that the application can "recall" pieces of your conversation.
