From the README
Principles and Practices of Engineering Artificially Intelligent Systems
📚 Hardcopy edition coming 2026 via MIT Press!
The open-source textbook that teaches you to build real-world AI systems — from edge devices to cloud deployment. Originally developed as Harvard University's CS249r course by Prof. Vijay Janapa Reddi, now used by universities and students worldwide.
Our mission: Expand access to AI systems education worldwide — empowering learners, one chapter and one lab at a time.
"This grew out of a concern that while students could train AI models, few understood how to build the systems that actually make them work. As AI becomes more capable and autonomous, the critical bottleneck won't be the algorithms - it will be the engineers who can build efficient, scalable, and sustainable systems that safely harness that intelligence."
