How AI Actually Works

Explain the machinery behind modern AI in plain language: examples become training signals, text becomes tokens and vectors, neural-network weights change through optimization, and inference generates an answer one step at a time. The episode also separates fluent prediction from verification and shows why the full AI system is bigger than the model alone. Chapters: 00:00 Intro 00:46 Data and training 02:29 Tokens and transformers 04:24 Neural networks 06:19 How training improves AI 08:21 What happens at inference 10:22 Closing This is an educational explainer. AI systems differ by architecture, training objective, data, hardware, and product design; the episode describes the common machinery at a high level rather than one universal implementation.
