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:\n\n```json\n[{\"role\": \"user\", \"content\": \"Hello\"}]\n```\n\nExample with multiple conversational turns:\n\n```json\n[\n  {\"role\": \"user\", \"content\": \"Hello there.\"},\n  {\"role\": \"assistant\", \"content\": \"Hi, I'm here to help. How can I help you?\"},\n  {\"role\": \"user\", \"content\": \"Can you explain LLMs in plain English?\"},\n]\n```\n\nExample with a partially-filled response from the model:\n\n```json\n[\n  {\"role\": \"user\", \"content\": \"What's the Greek name for Sun? (A) Sol (B) Helios (C) Sun\"},\n  {\"role\": \"assistant\", \"content\": \"The best answer is (\"},\n]\n```\n\nEach input message `content` may be either a single `string` or an array of content blocks, where each block has a specific `type`. Using a `string` for `content` is shorthand for an array of one content block of type `\"text\"`. The following input messages are equivalent:\n\n```json\n{\"role\": \"user\", \"content\": \"Hello\"}\n```\n\n```json\n{\"role\": \"user\", \"content\": [{\"type\": \"text\", \"text\": \"Hello\"}]}\n```\n\nSee [input examples](https://docs.claude.com/en/api/messages-examples).\n\nNote that if you want to include a [system prompt](/guides/querying-text-models), you can use the top-level `system` parameter \u2014 there is no `\"system\"` role for input messages in the Messages API.\n\nThere is a limit of 100,000 messages in a single request.",
