François Chollet posted advice for anyone wanting to learn to build large language models. He directed readers to chapters 15 and 16 of Deep Learning with Python, noting that chapter 15 explains why dot-product attention works. The third edition of the book adds coverage of generative AI and modern frameworks and is available online. Danielle Fong reposted the recommendation. The post frames the material as suitable for a 17-year-old or any age.
