Publisher review: Recent breakthroughs in AI have not only increased demand for AI products, they've also lowered the barriers to entry for those who want to build AI products. The model-as-a-service approach has transformed AI from an esoteric discipline into a powerful development tool that anyone can use. Everyone, including those with minimal or no prior AI experience, can now leverage AI models to build applications. In this book, author Chip Huyen discusses AI the process of building applications with readily available foundation models. The book starts with an overview of AI engineering, explaining how it differs from traditional ML engineering and discussing the new AI stack. The more AI is used, the more opportunities there are for catastrophic failures, and therefore, the more important evaluation becomes. This book discusses different approaches to evaluating open-ended models, including the rapidly growing AI-as-a-judge approach. AI application developers will discover how to navigate the AI landscape, including models, datasets, evaluation benchmarks, and the seemingly infinite number of use cases and application patterns. You'll learn a framework for developing an AI application, starting with simple techniques and progressing toward more sophisticated methods, and discover how to efficiently deploy these applications. Understand what AI engineering is and how it differs from traditional machine learning engineeringLearn the process for developing an AI application, the challenges at each step, and approaches to address themExplore various model adaptation techniques, including prompt engineering, RAG, fine-tuning, agents, and dataset engineering, and understand how and why they workExamine the bottlenecks for latency and cost when serving foundation models and learn how to overcome themChoose the right model, dataset, evaluation benchmarks, and metrics for your needsChip Huyen works to accelerate data analytics on GPUs at Voltron Data. Previously, she was with Snorkel AI and NVIDIA, founded an AI infrastructure startup, and taught Machine Learning Systems Design at Stanford. She's the author of the book Designing Machine Learning Systems, an Amazon bestseller in AI. AI Engineering builds upon and is complementary to Designing Machine Learning Systems (O'Reilly).

Publisher review: In the enchanted realm of Merilon, magic is life. Born without magical abilities and denied his birthright, Joram is left for dead. Yet he grows to manhood in a remote country village, hiding his lack of powers only through constant vigilance and ever more skillful sleight-of-hand. Forced to kill a man in self-defense, Joram can keep his secret from the townspeople no longer: he has no magic, no life. Fleeing to the Outlands, Joram joins the outlawed Technologists, who practice the long forbidden arts of science. Here he meets the scholarly catalyst Saryon, who has been sent on a special mission to hunt down a mysterious "dead man" and instead finds himself in a battle of wits and power with a renegade warlock of the dark Duuk-tsarith caste. Together, Joram and Saryon begin their quest toward a greater destiny—a destiny that begins with the discovery of the secret books that will enable them to overthrow the evil usurper Blachloch...and forge the powerful magic-absorbing Darksword.

Publisher review: The future of storytelling is here. Life has thrown Zelu some curveballs over the years, but when she's suddenly dropped from her university job and her latest novel is rejected, all in the middle of her sister's wedding, her life is upended. Disabled, unemployed and from a nosy, high-achieving, judgmental family, she's not sure what comes next. In her hotel room that night, she takes the risk that will define her life - she decides to write a book VERY unlike her others. A science fiction drama about androids and AI after the extinction of humanity. And everything changes. What follows is a tale of love and loss, fame and infamy, of extraordinary events in one world, and another. And as Zelu's life evolves, the lines between fiction and reality begin to blur. Because sometimes a story really does have the power to reshape the world.
