OpenAI crosses 1B weekly users

OpenAI says its models now reach more than 1 billion weekly active users and more than 2 million businesses. The company’s account of its infrastructure economics says people send roughly 50% more messages per day six months after joining, while Codex-driven agent work produces 99.8% of OpenAI’s weekly output tokens; The Verge independently timestamped the billion-user disclosure. For operators tracking GPT-5.6’s shift from chat to agents, the figure to file is the two-million-business distribution base: an OpenAI platform change can now become an enterprise default before rivals finish matching the feature.
