The era of the API wrapper is over. The era of the AI Engineer has begun.<\/strong><\/p>\n\n\n\n

Most developers are stuck in the “Prompt Engineering” trap. They write scripts that send data to a Black Box and hope for the best. They are passengers in the AI revolution, not drivers. This book changes that.<\/p>\n\n\n\n

Large Language Models Crash Course is a hands-on, line-by-line masterclass in the physics of Artificial Intelligence. We strip away the marketing hype, open the hood, and build a Generative Pre-trained Transformer (GPT) from absolute scratch using Python and PyTorch.<\/p>\n\n\n\n

You will not just learn how it works\u2014you will build the engine that makes it work.<\/p>\n\n\n\n

The engineering portfolio: <\/strong>By the end of this book, you will have architected the following system: <\/p>\n\n\n\n
