GPT (Generative Pre-trained Transformer)

GPT (Generative Pre-trained Transformer) is an AI model that learns from large-scale natural language text in advance and can generate natural, human-like text. Developed by OpenAI, versions such as GPT-3 and GPT-4 have drawn widespread attention for their ability to handle diverse language tasks—question answering, summarization, translation, and conversation—with high accuracy. GPT is trained in two stages—pre-training and fine-tuning—and is based on the Transformer deep learning architecture. By learning from enormous amounts of text data, it understands the context of words and sentences and predicts the most probable next token, enabling natural language generation. Primary use cases: • Conversational AI such as ChatGPT • Automatic generation of emails, articles, and ad copy • Auto-completion of programming code • Automated responses in customer support • Question-answering systems for education and learning assistance GPT's defining strength is the ability to produce responses that feel like genuine comprehension—going beyond traditional rule-based processing—making it a landmark generative AI model that has revolutionized the natural language processing field.
