How to check which model is currently in operation?

[riordant]

I can use :CopilotChatModels to choose a model. I can also set the model in init.lua. But is there a way to tell which model is currently in use?
For example, I could choose any of the available models in the model list, but it may not be activated, depending on my copilot level (free, personal, enterprise). Or, I could enter a model in init.lua, but if it's misspelled, I won't get an error on start, so it must fall back to some other model.
So, a way to see currently active model is needed.

You can't set an invalid model:

Failed to get response: {"error":{"message":"The requested model is not supported.","param":"model","code":"model_not_supported","type":"invalid_request_error"}}

But indeed, having a way to see which model is in use would be helpful. (todo)
