OpenAI CEO Sam Altman said Monday that ChatGPT has reached 800 million weekly active users, marking an increase of adoption among consumers, developers, enterprises, and governments.
ChatGPT’s impressive growth comes as OpenAI is on a race to secure as many AI chips and build as much AI infrastructure as possible. In August, OpenAI said it was on the cusp of reaching 700 million weekly active users , already an increase from 500 million weekly active users at the end of March.
