What would you like to see?

Prices and capabilities vary greatly between different providers and models. It would be fabulous to have a dropdown in the "Send a message" control that allows me to chose a provider. For simple requests I might use my local LLM or one of the cheaper commercial models. For harder questions I'd want to use one of the more powerful, but pricier models.

Ideally I'd be able to select "regenerate with model X" on an already generated response if the model I used didn't provide a satisfying answer.
