ChatGPT, developed by OpenAI, is an AI language model that leverages deep learning techniques to produce responses in natural language that closely resemble human-like conversation. It utilizes natural language processing (NLP), a subfield of AI, to comprehend, interpret, and generate human language effectively. The model was trained using large volumes of text data through both supervised and unsupervised learning methods for creating ways ChatGPT helps common users. As a result of this training, ChatGPT has acquired knowledge and the capability to generate comprehensible and contextual responses in natural language.
