How LLMs Like ChatGPT Actually Work and How to Build With Them

First meetup of the Columbus AI Engineering group.

We’ll kick things off with a practical, beginner-friendly discussion on:

How LLMs like ChatGPT actually work — and how to build real applications with them.

We’ll cover:

• what’s actually happening under the hood (at a high level)
• why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.)
• how people are building real systems with them today
• where things break in practice

This will be a short, informal talk (~15–20 min) followed by open discussion and Q&A.
Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join.
No slides, no fluff — just real conversation about real systems.
We’ll hang out afterward and get to know each other.
