Invited talk at Universidade Federal de Viçosa.

I gave a talk titled “Understanding What Happens Inside LLMs: Mechanistic Interpretability and How Attention Works” at Universidade Federal de Viçosa (UFV), where I did my BSc and MSc. It was a pleasure to talk about my research with UFV CS students and see (virtually) old friends. The talk was in Portuguese, but the slides are available in English.
