The Personal Assistant We'll Build › Let's Begin

You now have a map of where we're going. You know what we're building, why it matters, and what the journey will look like.

In the next chapter, we'll start with the foundation: understanding language models, the "brain" that powers your assistant. You'll learn how these models work (in plain English, no math required), how they generate responses, and why they sometimes behave in unexpected ways. You'll also write your first few lines of code to interact with one.
