OpenAI announced on Wednesday that it has surpassed one million business customers globally, calling the milestone the fastest growth in the history of business software platforms. The figure includes organizations actively paying for enterprise use through ChatGPT for Work or OpenAI’s developer platform.
The company said momentum has been driven by consumer familiarity with ChatGPT, which now records more than 800 million weekly users. This widespread usage has translated into faster enterprise rollouts, with ChatGPT for Work expanding to over seven million seats — a 40% increase in two months — and ChatGPT Enterprise growing ninefold over the past year.

To support this growth, OpenAI has launched a new suite of tools aimed at helping businesses scale AI adoption. These include “company knowledge,” which allows GPT-5 to integrate with platforms such as Slack, SharePoint, Google Drive, and GitHub to analyze and act across systems. Adoption of Codex, OpenAI’s coding model, has also risen tenfold since August, with companies like Cisco reporting significant reductions in code review times. Meanwhile, the AgentKit framework is enabling firms to develop AI agents more efficiently — with the Carlyle Group cutting development time in half and boosting agent accuracy by 30%.
OpenAI’s multimodal models are also seeing wider use, combining text, images, video, and audio capabilities through new APIs. The company said these advancements are helping organizations like Lowe’s, Indeed, and Intercom integrate generative AI into retail, recruitment, and customer service. According to a Wharton study cited by OpenAI, 75% of enterprises are already reporting positive returns from AI deployments, underscoring the technology’s expanding business value.
