The full form of Chat GPT is Chat Generative Pre-Trained Transformer. Chat GPT is an AI-powered model developed by OpenAI, a research organization aiming to ensure artificial general intelligence (AGI) benefits all of humanity. It is a deep learning model that has been trained on a large amount of text data to perform various natural language processing (NLP) tasks. Chat GPT is designed to understand and generate human-like text, making it ideal for engaging in conversations, answering questions, writing content, and more. It is built upon either GPT-3.5 or GPT-4, members of OpenAIs proprietary series of generative pre-trained transformer (GPT) models, based on the transformer architecture developed by Google. Chat GPT is fine-tuned for conversational applications using a combination of supervised and reinforcement learning techniques.
