Agentic AI Problem Set
20 Problems to Test Your Knowledge
How many can you get right?
I developed this problem set for my students to study the 20 key terms for Agentic AI that became popular in 2025.
In the spirit of AI by Hand ✍️, here is the design philosophy behind this problem set:
Problem-Driven. Every term begins with a problem statement—what motivated this idea in the first place.
Think-First: Instead of giving away the term immediately, you first get a multiple-choice question so you can think about which idea (term) best solves that problem.
Solution: On the next page, I reveal the correct term and explain how it addresses the problem.
Industry Insights: As a university professor, I don’t have industry experience. I’m fortunate to collaborate with Ofer Mendelevitch (Vectara), who contributes real-world industry perspectives.
Hope you enjoy this problem set! 😊
