ChatGPT is a state-of-the-art language model developed by OpenAI, a leading AI research organization. This model is trained on a massive corpus of text data, giving it the ability to generate human-like text, answer questions, summarize long documents, and even complete a given text prompt. In this article, we will delve into the details of what ChatGPT is, how it works, and its applications. What is ChatGPT? ChatGPT is a type of language model that is based on the transformer architecture. The transformer architecture is a deep neural network that has revolutionized the field of natural language processing (NLP) by allowing models to learn the relationships between words in a sentence. The ChatGPT model is trained on a large corpus of text data and uses this data to generate text that is similar to the text it was trained on. This allows it to respond to questions, summarize documents, translate languages, and even complete a given text prompt with high accuracy. How does ChatGPT work
