The AI Concepts Podcast

This episode dives into the hidden layer where language stops being words and becomes numbers. We explore what tokens actually are, how tokenization breaks text into meaningful fragments, and why this design choice quietly shapes a model’s strengths, limits, and quirks. Once you understand tokens, you start seeing why language models sometimes feel brilliant and sometimes strangely blind.

This episode explores the hidden engine behind how language models move from knowing to creating. It reveals why generation happens step by step, why speed has hard limits, and why training and usage behave so differently. Once you see this mechanism, the way models write, reason, and sometimes stall will make immediate sense.

This episode is about the hidden space where generative models organize meaning. We move from raw data into a compressed representation that captures concepts rather than pixels or tokens, and we explore how models learn to navigate that space to create realistic outputs. Understanding this idea explains both the power of generative AI and why it sometimes fails in surprising ways.

Welcome to Episode One of The Generative Shift. This episode introduces the core change behind modern AI, the move from discriminative models that draw decision boundaries to generative models that learn the full structure of data. Instead of predicting labels using conditional probability, generative systems model the joint distribution itself, which allows them to create rather than classify. This shift reshapes the math, the architecture, and the compute requirements, moving from compression focused networks to expansion driven systems that grow structure from noise. It is harder and more expensive, but it is the foundation of everything that follows. In the next episode, we will explore where this expansion lives by stepping into latent space and understanding how models represent meaning itself.

Hello everyone, and welcome to The Generative AI Series. I’m Shay, and this introductory episode is about why this series exists and who it is for.
