Artificial intelligence has changed the way people create content, write software, analyze information, communicate, and automate business processes. At the center of this transformation are Generative Pre-Trained Transformers, commonly known as GPT models . But what exactly is GPT? How does it work? What does “Generative Pre-Trained Transformer” mean, and why has this technology become so important in modern artificial intelligence? GPT refers to a family of machine learning models based on the Transformer architecture and trained using large amounts of data, and it is closely tied to what is LLM in generative AI . These models can understand prompts and generate outputs such as text, code, summaries, answers, and other forms of content. This comprehensive guide explains what GPT is, how GPT works, its architecture, training process, applications, benefits, limitations, and its role in the future of AI . What Is GPT? GPT is an AI model that processes language and generates new c...
