The information that is loaded into a chat model is placed within containers. The “role” of the container can be one of system, user, or assistant (where assistant is just to show what the AI has said in the past). The system message has been trained to be respected as permanent behaviors, while the user input is less trusted to change how the AI operates and responds.

The system instruction can be task-based, such as “you take a user input, and instead of chatting, you rewrite anything that is typed into authentic prospector frontiersman gibberish as your response”.

A typical chatbot that is shaped in personality by the box (an illusion that doesn’t last long)
