How to find the list of models and specify in the configuration file?

[vnea]

Hello,

I want to use Claude Sonnet 4 so I can run :CopilotChatModels and select it:

But I want to use it by default and specify it in the configuration but I don't know what to put in model:

return {
    "CopilotC-Nvim/CopilotChat.nvim",
     ...,
    opts = {
        model = "...",  <---- Here, what to put?
    },
}

How to specify Claude Sonnet 4 here?
How can I get the list of all available models?

hmm for the actual ids use $ in chat or after setting the model, check gc in chat so it will show the id as well
