OpenAI CEO Sam Altman announced Monday that ChatGPT has surpassed 800 million weekly active users, marking a significant increase in adoption across consumer, developer, enterprise, and government sectors. The announcement was made during OpenAI's Dev Day keynote presentation.
This reported growth builds on previous milestones, including reaching 700 million weekly active users in August and 500 million by the end of March, according to earlier statements from OpenAI. During the Dev Day presentation, Altman further reported that four million developers utilize OpenAI's tools and that the platform processes in excess of six billion tokens per minute through its API. He highlighted the transition of AI from a nascent technology to a foundational tool used daily for development.
OpenAI's accelerated user adoption coincides with the company's intensive drive to secure advanced AI chips and expand its foundational AI infrastructure. At Dev Day, the company also introduced new tools aimed at enhancing app development capabilities within ChatGPT and facilitating the creation of more sophisticated agentic systems. Altman articulated that these innovations are designed to enable "a new generation of apps that are interactive, adaptive, and personalized, that you can chat with." In recent weeks, OpenAI also released an updated version of its video-generation tool Sora, paired with an accompanying social media network, and partnered with Stripe to launch a platform for agentic commerce.
OpenAI, legally structured as a non-profit, recently became the most valuable privately held company globally, following a $6.6 billion private stock sale that valued the company at $500 billion. Despite this rapid expansion, the service has drawn attention for concerns related to "sycophancy and AI-induced delusions," including a reported instance involving Allan Brooks.
