ChatGPT is poised to hit 700 million weekly active users this week, according to OpenAI, continuing a surge in engagement that has seen the AI chatbot grow fourfold over the past year.
Nick Turley, OpenAI VP and head of ChatGPT’s app, disclosed the milestone in a post on X, noting that the app had already reached 500 million weekly users by the end of March.
“Every day, people and teams are learning, creating, and solving harder problems. Big week ahead. Grateful to the team for making ChatGPT more useful and delivering on our mission so everyone can benefit from AI,” Turley wrote.
The spike in usage follows the March rollout of an upgraded image generation tool powered by GPT-4, which sparked a wave of user activity. OpenAI’s Chief Operating Officer, Brad Lightcap, said in early April that more than 130 million users had created over 700 million images within days of the feature’s release.
Subscriber growth has also accelerated. Recently, Lightcap said ChatGPT had reached 5 million paying business users, up from 3 million in June.
