Deep Dive into LLMs like ChatGPT – YouTube

March 27, 2025

This is a general audience deep dive into the Large Language Model (LLM) AI technology that powers ChatGPT and related products. It is covers the full training stack of how the models are developed, along with mental models of how to think about their “psychology”, and how to get the best use them in practical applications. I have one “Intro to LLMs” video already from ~year ago, but that is just a re-recording of a random talk, so I wanted to loop around and do a lot more comprehensive version.

Got 3 and a half hours and are keen to get a solid idea about how LLMs work? Andrej Karpathy was a founding member of OpenAI, and there’s few more knowledgable about the topic than he is.
