    Use Cases & Benefits

    • Teaches how to build scalable, efficient, and sustainable machine learning systems from edge devices to cloud deployment through an open-source textbook.
    • Provides a comprehensive full-stack approach to ML systems engineering, combining theory, practical labs, and real-world system design in one resource.
    • Use for university courses or self-study to gain deep knowledge of ML system design, deployment, and operations beyond model training.
    • Use for educators seeking ready-made course materials, labs, and teaching guides to instruct students on building production-ready AI systems.
    • Use for developers and engineers aiming to implement resource-efficient ML on embedded, mobile, and IoT devices with practical system engineering principles.

    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."
