Intro to AI Agents — we’ve started! User: "Why does AI always misunderstand my request?" Their prompt: "that thing from yesterday" Last Saturday, we kicked off our first session with a diverse group of students, data scientists, analysts, software engineers, and professionals from other fields. Nikita Severin took us from AI fundamentals to modern LLMs. It was a lot of material to cover — and we’re happy to report that everyone survived this trial by dense LLM theory! Let's see how many survive the next one... 😈

We've already received 40+ submissions — we're very excited that this initiative has attracted attention in the community! A few common questions we've received: Q. Why is this course free? A. The Faculty of Mathematics is generously hosting us at no cost, and we wanted to pass that on — so there's no fee for participants. Q. Is this course only for students? A. No, it's open to both students and professionals. We believe that mixing people with different background is beneficial for everyone. Q. Will the sessions be recorded? A. Yes, although it's mainly for participants who missed a session to be able to catch up. It's best to attend in person. If you're interested — register by March 8! Registering early helps us plan and may mean faster approval. Details: https://datasanity.dev/intro-to-ai-agents-belgrade-2026.html Registration form: https://forms.gle/gTZD3ZsQXrAvKjDr7
