ChatGPT

ChatGPT is an AI chatbot developed by OpenAI, launched in November 2022. Built on the GPT (Generative Pre-trained Transformer) family of large language models, ChatGPT became the fastest-growing consumer application in history, reaching 100 million users within two months of launch. The platform enables natural language conversations, code generation, creative writing, analysis, and problem-solving across virtually any domain. ChatGPT is available in free and paid tiers (ChatGPT Plus, Team, and Enterprise), with the paid versions offering access to the most capable models (GPT-4o and beyond), image generation via DALL-E, web browsing, code execution, and custom GPTs. OpenAI has integrated ChatGPT into workflows through plugins, an API, and partnerships with companies like Microsoft (which has invested over $13 billion in OpenAI). The tool has transformed industries from education and customer service to software development and content creation, sparking both excitement and debate about AI's role in society.
