ChatGPT is an advanced AI chatbot developed by OpenAI that understands and generates human-like text based on input prompts. It leverages machine learning and natural language processing (NLP) to engage in meaningful conversations, answer queries, and assist with various tasks. From casual chat to professional communication, ChatGPT adapts to different contexts, making it an indispensable tool for businesses and individuals alike.
ChatGPT, developed by OpenAI, is an advanced generative AI chatbot built using the GPT (Generative Pre-trained Transformer) model family. Launched in November 2022, it has evolved from a simple text-based assistant into a full-scale AI productivity tool. The most recent model, GPT-4o (Omni), supports text, image, voice, and file input, making ChatGPT truly multimodal.
It is used by millions globally for content creation, education, programming, personal productivity, business automation, and more.
