I'm planning to add copilot, cursor and cline but feel free to contribute to the repo if you would like to do that and will look for ways to use the mini versions of the models as well when I integrate copilot CLI
Problem is, Copilot CLI doesn't really supports free or mini models. You have very tight choice of models. This looks like product decision. I understand why they won't allow you to use the free models on CLI, but not being able to use the (pay for) mini models is beyond me.
