You can set up your model provider when you first open the app or later in app settings.
 
 You must sign in with a {% data variables.product.github %} account to use the app, but you do not need a {% data variables.product.prodname_copilot_short %} plan if you use your own model provider. If you do have a {% data variables.product.prodname_copilot_short %} plan, you can use both your own model provider and {% data variables.product.github %}-hosted models in the same app.
