Today, as a result of significant advances in Artificial Intelligence (AI), technology giants such as Google, Microsoft,Apple and many other companies or institutions use and continue to develop artificial intelligence models for specificpurposes. Different artificial intelligences, which are continuously trained using long and various training methods, are customized for specific purposes and serve to provide benefits in those areas. ChatGPT, a chatbot being developed by OpenAI, which we have started to hear a lot about recently, has the potential to significantly change the way we interact with technology. The most important skill of the ChatGPT chatbot is its ability to understand texts, images and generate new texts with high accuracy, even almost human-like, with the help of the huge amount of data it processes during its training. In this paper, we present an overview of the developments in the Large Language Model (LLM), ChatGPT (Generative Pre-trained Transformer), which has been the subject of much debate, concern, and even conspiracy theories, and the benefits or problems it may cause. This opens up ground-breaking possibilities for the areas of Natural Language Processing (NLP) and Natural Language Understanding (NLU). Built on the GPTlanguage model, ChatGPT offers a wide range of possibilities, from law to medicine, from mathematics to finance,from cademic article writing to language translation and even security vulnerability detection.
