The Stanford course on how ChatGPT-style AI works is free on YouTube, including exams.
CME 295 starts with how a model reads text and goes all the way to training, reasoning models, agents and how to test them. Last year's run is fully online: 9 lectures, each close to 2 hours. The first one has almost a million views.
The slides, midterm, and final with solutions are on the course website, along with a free illustrated cheat sheet. Afshin and Sharabin Amadi teach it.
This fall version is now running and posting its recordings as it goes. Five lectures came out. Still to come: AI agents with MCP and skills, how to judge a model, and diffusion language models, another way to generate text.
