Generative AI with LangChain: Build large language model (LLM) apps with Python, ChatGPT and other LLMs

Book Synopsis: Get to grips with the LangChain framework to develop production-ready applications, including agents and personal assistants, integrating with web searches and code execution. Purchase of the print or Kindle book includes a free PDF eBook.

Key Features

• Learn how to leverage LLMs’ capabilities and work around their inherent weaknesses
• Delve into the realm of LLMs with LangChain and an in-depth exploration of their fundamentals, ethical dimensions, and application challenges
• Get better at using ChatGPT and GPT models, from heuristics and training to scalable deployment, empowering you to transform ideas into reality

Book Description

The ChatGPT and the GPT models by OpenAI have brought about a revolution in the way we think about the world ― and not only in how we write and research, but in how we can process information. This book discusses the functioning, capabilities, and limitations of LLMs including ChatGPT and Bard. It also demonstrates how to use the LangChain framework to implement production-ready applications based on these models, such as agents and personal assistants, and integrate with other tools such as web searches and code execution.

As you progress through the chapters, you’ll use transformer models and diverse attention mechanisms, refining the intricate process of training and fine-tuning. You'll get to grips with data-driven decision-making with automated analysis and visualization using pandas and Python. You’ll also take a closer look at the heuristics of how to use these models, prompting, training and fine-tuning, and deploying at scale.

By the time you’ve finished this book, you’ll have a deep understanding of what makes LLMs tick and how to make the most of them.
