ChatGPT FIVE days after its launch last year, OpenAI’s ChatGPT had been used by a million people. The number almost crossed 100m with 1.8 billion visits recorded by the OpenAI site, making it the fastest growing application. In contrast, popular social media applications took much longer — two and a half months for Instagram, 10 months for Facebook and two years for Twitter to touch the million-user mark. ChatGPT is designed to generate human-like text in a conversational mode. Deriving information from books, websites and other digital resources, it responds to user queries using natural language processing. The chatbot composes essays, stories and poems and translates and performs other tasks too.
