OpenAI’s flagship AI chatbot, ChatGPT, returned to solid growth in the latter half of 2024. While it took ChatGPT nine months to grow from 100 million weekly active users in November 2023 to 200 million in August 2024, it’s now taken less than six months for the app to double those numbers yet again. Also, users of the ChatGPT mobile app have increased by 5% to 15% every month over the past year.
