Chat GPT: A Peruse into its Journey, Applications, and Future Prospects

Abstract
OpenAI developed the remarkable ChatGPT, which sparked a revolution. It dominated the market as the finest Artificial Intelligence(AI) Chatbot. When a user entered a query into ChatGPT, it employed Natural Language Processing (NLP) operations to encode and process the input through the transformer model, producing coherent appropriate responses in natural human language. It combined the Large Language Model (LLM) with the idea of a Generative Pre-trained Transformer (GPT) that made it the most potent conversational AI. This paper aimed to highlight ChatGPT as a new generation AI. Additionally, a diagrammatic illustration of the GPT chronology and a number of ChatGPT applications had been provided. The specific applications such as financial assistance, scientific writing, academics, communal health, etc, were briefly discussed. Finally, a review table was created to provide an overview of several publications and discussed the application area along with the future scope as described in the research findings. The paper also briefly discussed its progression into GPT-4. Keywords - ChatGPT, Conversational AI, GPT, GPT-4, LLM, NLP
