Generative AI refers to artificial intelligence systems capable of creating new content-such as text, images, or music-by learning patterns and structures from existing data. Models utilize advanced algorithms to generate human-like outputs based on the input they receive. This book aims to explore and demystify the technology behind AI systems that generate new content. By examining how models learn from existing data and employ sophisticated algorithms, the book seeks to educate readers on the principles, applications, and implications of this transformative field. It also includes case studies across various niches and industries. This book is the culmination of 12 months of my research, and I hope you enjoy reading it. I highly recommend it to postgraduate students, as it covers many aspects of generative AI and its future prospects.
