ecent progress in large language models has pushed the boundaries of natural language processing, setting new standards for performance. It is remarkable how artificial intelligence can mimic human behavior and writing style in such a convincing way. As a result, it is hard to tell if a human or a machine wrote something. Deep learning and natural language processing have recently advanced large language models. These newer models can learn from large amounts of data to better capture the nuances of language, making them more accurate and robust than ever before. Additionally, these models can now be applied to tasks such as summarizing text, translating between languages, and even generating original content. ChatGPT is a natural language processing (NLP) model developed in 2022 by OpenAI for open-ended conversations. It is based on GPT-3.5, the third-generation language processing model from OpenAI. ChatGPT can power conversational AI applications like virtual assistants and chatbots. In this paper, we describe the current version of ChatGPT and discuss the model's potential and possible social impact.
