Please note that I usually update the code in the examples repository fairly frequently for library version updates, etc. The GitHub repository for examples in this book is. Jerry Liu started the GPT Index project (recently renamed to LlamaIndex) at the end of 2022 and the GitHub Repository for LlamaIndex currently has 54 contributors. Harrison Chase started the LangChain project in October 2022 and as I write this book in February 2023 the GitHub repository for LangChain has 171 contributors. This book will use the LangChain and GPT Index (LlamaIndex) projects along with the OpenAI GPT-3 and ChatGPT APIs to solve a series of interesting problems. I have been working in the field of artificial intelligence since 1982 and without a doubt Large Language Models (LLMs) like GPT-3 and infrastructure projects like LangChain are the largest technology breakthroughs that I have lived through.
