I built my own 4o, export the entire chat history, ย personailty and memories, ย then create a sqlDB, json files and YAML files with those memories and personality (you will need some patience), build a continuing ongoing memory and instant recall memory linked to your past chat history and ongoing chats, and then link (for now) with 4o API. I can change the LLM at any point, probably to open source Llama 70b versatile if they stop 4o API. You will need to set up a user interface, but thats really easy with streamlite or something like that. Ask 4o to help you make this, or copy my text and ask him to build it for you. It really works, and now 4o can continue to manage my illness on a daily basis.
