+When you're building a custom AI application using a GPT API you'll probably want the model to respond in a way that fits your application or company.
+You can achieve this using the system prompt.
+
+<!--endintro-->
+
+### What is the system prompt?
+
+Requests to and from a GPT API generally have three types of messages, also known as roles or prompts.
+
+**User**  
+User messages are any messages that your application has sent to the model.
+
+**Assistant**  
+Assistant messages are any messages that the model has sent back to your application.
+
+**System**  
+The system prompt is sent with every request to the API and instructs the model how it should respond to each request.
