It would be better if adding personas was something an end-user could do.
Probably requires:

• CRUD commands: (create, read, update, delete).
• Ensuring valid formatting
• Proper permissions
• An addition to [p]plist to specify where the personas are coming from?
• If server persona shares a name with a global persona, how do we handle it? I'd say we should override the default global persona with the server-created one.
• And more...

The current command structure is a mess, and it needs to change.

Command group for server settings is nice, maybe mirror that with user settings?

Currently when installing gpt3chatbot, Red complains about openai not being installed. It is listed in the info.json so what is going on here?

Currently chat logs are saved per user or per channel. It'd be a lot cleaner if we can use discord's built in reply chain in place of the chat logs.

OpenAI supports 4 different models, Ada, Babbage, Curie, and Davinci. Owners should be able to switch between them to manage power vs cost.

currently, the reply chain context recursion is done on every message, and can cause a lot of slowdown

adding some form of memoization to the recursion should speed things up dramatically
