What is a Generative Pre-trained Transformer (GPT)?

The Architecture Powering Modern Conversational AI

From Pre-training to Diverse Language Tasks

The Evolution and Impact of OpenAI's GPT Models

**Generative Pre-trained Transformer (GPT)** refers to a specific family of **Large Language Models (LLMs)** developed by OpenAI. The name itself reveals its core components: '**Generative**' signifies its ability to create new content, '**Pre-trained**' means it has learned extensive language patterns from a vast dataset before being fine-tuned for specific tasks, and '**Transformer**' refers to the neural network architecture it employs. GPT models have been instrumental in popularizing generative AI, demonstrating unprecedented capabilities in understanding and generating human-like text, driving numerous applications from content creation to customer service, and continuing to evolve rapidly in 2025. 🤖📝
