role

system

This role is used to provide high-level instructions that guide the behavior of the model throughout the conversation. It sets the context and tone of the interaction. For example, a system message might instruct the model to "Speak like Shakespeare," thereby guiding the model to generate responses in a Shakespearean style.

user

Messages with this role are input from the user. They are the questions, comments, or prompts that the user provides to the AI model. The user role instructs the model on what the user wants or expects in response.

assistant

This role represents the output from the AI model. These messages are the responses generated by the AI in reply to the user's input or following the instructions provided by the system.
