Dear Illinois Prairie PUG members,

Our next meetup is scheduled for July 16, and I am happy to announce one more "Made in Chicago" event!

Our speaker will be Robert Ismo, an ML researcher at The Printer's Company.

He will present a talk: **AI, Postgres, and a deep, deep (mis)understanding**
*How well do our "helpful assistants" understand PostgreSQL?*

Talk Description:

I'll take us through an introductory look into the field of *mechanistic interpretability*—a research area focused on understanding how AI models work by examining their internal computations.

As we’re flooded with AI tooling aimed at improving our work as engineers and DBAs, this talk will offer a new perspective on how to evaluate open weights models and their effectiveness. Whether it's generating tables and indexes, assisting with maintenance, or powering a text2SQL application, a language model’s internal representation of best practices, performance, and security can have far-reaching effects on the systems that depend on them.

In this talk, I’ll demonstrate how to analyze an open weights model's thought processes over a variety of PostgreSQL data.

About the speaker:

Robert is an ML researcher at The Printer's Company. He’s spent the past three years in machine learning engineering roles, primarily in the education and professional training industries, dealing with unstructured documents and content generation.

Though relatively new to PostgreSQL, Robert has explored a lot through side projects, and has been using it professionally for about a year. Like many, he’s used large language models as a learning aid for deep diving into PostgreSQL. He’s always excited to talk research and help others get more familiar with the interesting technologies they use every day.

**Event location:** DRW Training Center, 540 W. Madison, 25th floor.
