Lesson 1 (Working Draft)

Why AI Feels Different

Most software tools are deterministic.

Given the same input, they produce the same output.

Large language models are different.

They are collaborative reasoning systems that generate responses based on the information currently available, statistical patterns learned during training, and the instructions you provide.

This distinction changes how engineers should work with them.

Rather than asking:

How do I write the perfect prompt?

A more productive question is:

How do I design a workflow that consistently provides the model with the information it needs to succeed?

That question forms the foundation of AI Engineering and will guide the remainder of this course.
