@thegreatestcompany, can you please expand why are these changes necessary? There is a sample config in the root.

Are we going to use "base_url" instead of "api_base" here?

If yes, should we wait #383 first?

This PR is adding a new file to the notebooks folder. I still see it using api_base

#383 and all the subtasks for #203 are merged to the dev/v0.2 branch. We won't merge #393 to main until all the subtasks are solved.

Not quite sure what the purpose of this PR is

[gagb]

I think this PR is not necessary given the instruction number 2 in https://github.com/microsoft/autogen#quickstart

@thegreatestcompany if this makes sense, I'd like to close this PR.

@gagb @thegreatestcompany Seeing as there is no response i will go ahead and close this PR
