As ChatGPT becomes a global sensation, the real intelligent "brain" behind the scenes is the Large Language Model technology. Generative Large Language Models are ushering in a new era, and technological breakthroughs based on generative pre-trained Large Language Models are enabling both individual-level and industrial applications. This is bound to trigger a new round of intellectual revolution and industrial restructuring, allowing new brain-computer collaborations. But at the same time, bubbles will emerge along with the opportunities. For this reason, this book provides an in-depth analysis and elaboration of the technology, application, and industrial changes in the era of large language models. The book firstly presents technical know-how through personified approaches, vividly explains the principles behind the large language models represented by ChatGPT, and provides an in-depth analysis of the fundamental capability that empowers large language models to change technology and industry. Secondly, the book uses the history and logic of the three industrial revolutions as a reference to depict how large language models will bring society to the era of the Intelligence Revolution and Brain-Computer Collaboration, and provides suggestions for individuals and enterprises to cope with this change.
