I ran this two-hour hands-on workshop twice at the WeAreDevelopers World Congress 2026 in Berlin. The first session booked out quickly, so a second session was added for the next day. Participants worked directly with Large Language Models to learn how they function under the hood and to practice techniques for getting better results from them.
