Make it easier to setup other models in the CLI

[kannib]

Maybe it's just me but I've found it unnecessary difficult to get it working with Gemini in the CLI. Not sure where is pulling the settings from (the settings folder on my directory is empty) but it refuses to use Gemini and says I need an OpenAI key. I tried to find samples and further instructions on how to properly use the CLI but most of the examples are for python scripts. Why isn't there a default .JSON I can just edit?
