[1hr Talk] Intro to Large Language Models

In a one‑hour general‑audience talk, Andrej Karpathy introduces large language models—the core technology behind ChatGPT, Claude, and Bard—explaining how they are trained and run, why they sometimes generate hallucinations, and how fine‑tuning can steer them toward helpful assistant behavior. He reviews scaling laws, tool use such as browsing and calculators, multimodal extensions, and the idea of treating LLMs as an operating system. The session also covers security concerns, including jailbreaks, prompt injection, and data poisoning, and concludes with practical take‑aways for responsible deployment.
