What is changing?
OpenAI Economic Research’s October 14, 2026 report says businesses across the European Union are moving beyond question answering toward agents that carry tasks from planning through completion. In OpenAI’s EU sample, Codex and ChatGPT Work account for more than half of output tokens generated by Enterprise customers.
Weekly active users of Codex and ChatGPT Work among small and medium businesses have grown more than eightfold since May 2026. Adoption is uneven: across Enterprise accounts, the share of output tokens attributed to these tools ranges from 22% in Slovenia to 85% in Lithuania.
The report also says the most intensive EU firms generate over four times as many output tokens per active user as typical EU firms, while global frontier firms still operate at more than twice the intensity of EU frontier firms. The findings are based on OpenAI customer samples and should not be treated as an independent survey representing all EU businesses.
