I was about to work on this yesterday, I thought adding this on the conversation itself is nicer (then you can easily switch). What do you think?

Edit: Also what chatgpt does

[anthony2261]

Yeah I like the way it looks, how about both on the settings page and in the chat?

After our discussion, agreed to delay this for a while.

Other models seems to be performing much worse in some ways (even though they are more powerful). So let's wait until we have a regression test suite, then we can enable some of those models after testing them thoroughly.

I think once we tackle this again, it makes sense to refactor it in a generic way so as to support different LLMs + local LLMs potentially. Code for this is pretty unorganized and very specific to open AI right now (settings and validation, selecting the LLM in code, etc.)
