// questions

Before you ask.

Is this the same TheLion.AI as the Polish one?›

Yes — same team, same research projects, same teaching methodology. TheLion.AI started in Poland; Atlanta is its US home. The papers and open-source tools are shared across both.

When is the first event?›

Fall 2026, in Atlanta. The date is announced on our Luma calendar first — join the list and you'll get it as soon as it's set.

Who are the events for?›

AI engineers, researchers, students and founders — anyone building with AI or curious enough to start. Talks are technical but the room is beginner-friendly, and the workshop nights assume nothing beyond a laptop.

Do I need to work in healthcare?›

No. Our research is in medical AI, but the meetups and workshops cover AI broadly — LLMs, computer vision, RAG, evaluation and everything around shipping models.

What does it cost?›

The meetups, workshop nights and worksheets are free. Company training and executive mentoring are paid — that's what funds the community work.

Can my company sponsor or host?›

Yes. Sponsoring an event or hosting one at your office puts your brand and your open roles in front of Atlanta's AI builders. Write to us and we'll send the details.
