When creating a new `Message`, you specify the prior conversational turns with the `messages` parameter, and the model then generates the next `Message` in the conversation. Consecutive `user` or `assistant` turns in your request will be combined into a single turn.\n\nEach input message must be an object with a `role` and `content`. You can specify a single `user`-role message, or you can include multiple `user` and `assistant` messages.\n\nIf the final message uses the `assistant` role, the response content will continue immediately from the content in that message. This can be used to constrain part of the model's response.\n\nExample with a single `user` message:"}
