Part 1:Introduction to Generative AI and LlamaIndex

As this ebook edition doesn't have fixed pagination, the page numbers below are hyperlinked for reference only, based on the printed edition of this book.

This first part begins by introducing generative AI and Large Language Models (LLMs), discussing their ability to produce human-like text, their limitations, and how Retrieval-Augmented Generation (RAG) can address these issues by enhancing accuracy, reasoning, and relevance. We then progress to understand how LlamaIndex leverages RAG to bridge the gap between LLMs’ extensive knowledge and proprietary data, elevating the potential of interactive AI applications.

This part has the following chapters:

• Chapter 1, Understanding Large Language Models
• Chapter 2, LlamaIndex: The Hidden Jewel - An Introduction to the LlamaIndex Ecosystem
