What Is ChatGPT in Plain English
ChatGPT is an AI-powered chatbot created by OpenAI that can hold a conversation answer questions write text explain complex topics generate code and much more. Unlike a search engine that returns links to existing content ChatGPT generates new original responses based on your specific question or request in real time.
How ChatGPT Works — Simply Explained
ChatGPT is built on a technology called a Large Language Model LLM. During training the model processed an enormous quantity of text from the internet — books articles websites code and more — and learned statistical patterns about how language works which words follow which other words how concepts relate to each other and how to respond helpfully to human requests. When you ask ChatGPT a question it does not look up the answer in a database — it generates a response based on learned patterns. This is why it can answer questions about virtually any topic and why it can also make mistakes.
