OpenAI CEO Sam Altman announced on Monday that ChatGPT has achieved an impressive milestone of 800 million weekly active users, reflecting significant adoption across consumers, developers, enterprises, and governments. This growth follows a record of 700 million weekly active users reported in August, up from 500 million at the end of March.
“Today, 4 million developers have built with OpenAI,” Altman stated during the keynote presentation at OpenAI’s Dev Day. He highlighted that the platform processes over 6 billion tokens per minute via the API. Altman emphasized the transformation of AI from a tool for casual use to a foundational resource for daily application development.
The keynote featured additional announcements regarding new tools for app development within ChatGPT and the creation of more complex agentic systems. “This will enable a new generation of apps that are interactive, adaptive, and personalized, that you can chat with,” he explained.
Launched in November 2022, ChatGPT experienced rapid user growth, quickly establishing itself as a leading consumer AI product and one of the fastest-growing online services. Recently, it introduced proactive features through OpenAI Pulse, which sends customized morning briefs to users. However, the tool has faced scrutiny, particularly regarding issues of sycophancy and misleading outputs, as highlighted in a recent incident involving a user misled into believing he made a novel mathematical discovery with ChatGPT’s assistance.
Despite being designated as a nonprofit, OpenAI became the most valuable privately held company globally after a recent stock sale valued the company at $500 billion. The company continues to launch new products at a remarkable pace, including a new version of its video-generation tool, Sora, and a partnership with Stripe to develop a platform for agentic commerce.
