By the end of this course, you'll have a functional AI agent with core logic (name, instructions, and model), registered in Mastra for execution. You will be able to run it locally using `mastra dev` and interact with it via an API endpoint (or integrated UI) to send prompts and receive AI-generated responses. Your customized AI Agent will serve as the foundation for building advanced AI-powered applications, which we will cover in future lessons in this series on Mastra AI.
