Free, open-source AI engineering course where you build each algorithm by hand: 523 lessons, now as EPUB/PDF books [P]

AI Engineering from Scratch is a free, open-source, MIT-licensed curriculum offering 523 lessons across 20 phases. It covers topics from linear algebra and backprop to transformers, LLMs, agents, and production serving. The course emphasizes building algorithms by hand with stdlib-first code, allowing users to see every step. It is now available as EPUB/PDF books, and a coding agent can provide a placement quiz and study plan via "npx skills add rohitg00/ai-engineering-from-scratch" and then "/start-learning."

Unlike other AI courses that rely on libraries, this curriculum uniquely emphasizes building every algorithm by hand using stdlib-first code, offering a deeper understanding of each step.
