Microsoft-backed OpenAI’s ChatGPT weekly users doubled in less than a year

Microsoft-backed OpenAI announced that its artificial intelligence (AI) chatbot has more than 200 million weekly active users, doubling in less than a year. OpenAI reported 100 million weekly active users in November 2023.
OpenAI spokesperson Taya Christianson confirmed the number to The Verge. She said that 92% of Fortune 500 companies are using OpenAI’s products, further adding that the use of its automated Application Programming Interface, or API, which allows software programs to talk to each other, has doubled since the launch of ChatGPT-4o mini in July.
