OpenAI launched ChatGPT in late 2022 with low expectations, but it quickly gained immense popularity, crashing servers within hours. Despite concerns over its accuracy and reliability, ChatGPT evolved into a $4 billion revenue tool with 300 million weekly users. OpenAI aims to enhance its capabilities beyond a chatbot, focusing on integrating AI more deeply into users' lives. As competition grows, the company is exploring new functionalities while addressing ongoing challenges with accuracy and monetization.
