Generative AI has moved from novelty to infrastructure. This book shows you how to use it well, and how to build with it.

Generative AI: From Foundations to AI-Powered Products is a practical guide that takes you from how large language models actually work to shipping real AI-powered tools. Across 33 chapters you will learn:

• How modern models are trained, and how to choose the right one for a task
• Prompting and context engineering that produce reliable, repeatable results
• Turning one-off chats into reusable systems, workflows and autonomous agents
• Research, verification, privacy and human oversight, so accuracy is never optional
• Building websites, landing pages and functional AI products, with or without traditional coding
• AI image, video and audio production, including costs, copyright and consent
• A complete builder workflow and a practical playbook to start in week one

Written for developers, entrepreneurs, small-business owners and professionals, with examples that include the Indian market. It focuses on principles that stay useful even as model names and tools change.
