Which GPT model is used by copilot.lua

[pidgeon777]

I am writing to inquire about the specific version of the Copilot model that is being utilized by copilot.lua. The existence of multiple versions of the Copilot model, as depicted in the image below, has piqued my interest.

In addition to this, I am also interested in knowing whether copilot.vim uses the same version of the model as copilot.lua.

Furthermore, I would like to know if there is a method to dynamically determine the version of the model being used, possibly through a command.

Lastly, I am curious to know if it is possible for the user to select a different model version for use.
