GPT stands for "Generative Pre-trained Transformer", a smart neural network pattern that is used for machine text generation This smart neural network uses GPT to customize machine language, voice processing, machine translation, and other intelligent services GPT-3 It is the third version of GPT models AI that has been trained on a large set of new natural data, , the study analyzed the linguistic model or Chat-GPT by reviewing it, identifying its components, the search mechanism within it, analyzing the retrieved results, and indicating the extent to which it achieves the desired purpose. As well as a comparison between it and search engines to identify the similarities and differences between them, and the study relied on the analytical descriptive approach, and reached a number of results, the most important of which was the distinction of Chat-GPT program from chat programs and other NLP systems in ultra-realistic conversation skills, including That's the ability to ask follow-up questions, and admit errors. Chat-GPT also uses advanced machine learning algorithms to generate response text according to user inputs and queries. Chat-GPT does not search any databases, but rather generates text based on the patterns it learns from its training data. The study recommended that Chat-GPT should support the Arabic language with better writing, just like other foreign languages, and the need to conduct training and continuous updates every month; So that everything new is added to it in order to be able to provide modern, sophisticated and appropriate answers to the daily life .
