OpenAI Says Enterprises Shift AI From Assistance to Execution

Companies are moving generative AI beyond one-off writing and search tasks toward agentic systems that can complete multistep work across business processes. OpenAI’s report, released December 8, 2025, combines deidentified customer usage with a survey of 9,000 workers at nearly 100 enterprises. It tracks how ChatGPT and Codex are becoming embedded in repeatable workflows, making organizational readiness — including governance, training and system integration — a growing source of competitive advantage as model access becomes more widespread.

Weekly messages in ChatGPT Enterprise rose about eightfold in the year since November 2024, while the average worker sent 30% more messages. Weekly users of Custom GPTs and Projects climbed 19-fold in 2025, and those tools handled about 20% of Enterprise messages. Codex engagement accelerated over the six weeks covered by the report, with weekly active users doubling and messages rising roughly 50%. Firms in the top 5% of adoption intensity generated twice as many messages per seat as the median enterprise and seven times as many messages to GPTs.
