This paper provides an overview of generative artificial intelligence (Gen-AI), its underlying concepts, and its applications in business and education. It begins by introducing the basic concepts of artificial intelligence (AI), including machine learning, deep learning, and artificial neural networks. The paper then discusses the different types of AI, such as artificial narrow intelligence (ANI), artificial general intelligence (AGI), and artificial super intelligence (ASI), and explains their characteristics. It also covers the role of symbolic AI, machine learning, and deep learning in AI development. The paper then introduces generative AI, explaining its ability to generate content such as text, images, and audio. It discusses the key components of generative AI, including natural language processing (NLP), large language models (LLMs), and the transformer model. The paper also explores the applications of generative AI in business and education, highlighting its potential to enhance creativity, improve productivity, and support learning. However, it also addresses the challenges and ethical concerns associated with generative AI, including issues of accuracy, explainability, intellectual property, and security. The paper concludes by emphasizing the need for responsible use of generative AI and the importance of addressing its challenges to ensure its beneficial integration into society.This paper provides an overview of generative artificial intelligence (Gen-AI), its underlying concepts, and its applications in business and education.
