OpenAI said AI agents generated 55% of output tokens in its business accounts across the European Union by September 30, a finding that signals growing use of its agent products but does not mean agents handled most company AI tasks. Related context on OpenAI’s enterprise AI stack explores how the company is bringing AI into business data workflows. The figures come from the company’s October 14 report and cover ChatGPT Enterprise and ChatGPT Business customers in the 27 EU member states.

OpenAI Economic Research’s report, Europe’s Agentic Opportunity: Moving from Breadth to Depth with AI Agents, counts output from Codex, OpenAI’s coding agent, and ChatGPT Work, an agent mode launched in July 2026 that can work with files, browsers and company tools. As of September 30, Codex accounted for 34% of output tokens in the covered accounts and ChatGPT Work for 21%; standard ChatGPT accounted for the remaining 45%.

The company also reported that weekly active users of Codex or ChatGPT Work among businesses with 200 or fewer users increased 8.1 times from the first week of May to the week ending October 5. Every EU member state recorded at least fivefold growth in that measure. Belgium, Italy and Luxembourg had the highest reported multiples, at 12.1, 10.8 and 10.0, respectively. OpenAI did not provide absolute user totals alongside those growth figures.

Reported agentic output shares varied by country, from 85% in Lithuania and 81% in Cyprus to 22% in Slovenia and 26% in Austria. Germany’s reported share was 51%, placing it 17th among the 27 member states. These are figures for OpenAI’s own business accounts, not a census of AI use across national economies.

What the 55% Share Measures

The report offers a view of how one AI provider’s business customers are using its products, and points to rapid uptake of agent tools within that customer base. For companies weighing whether to expand agent access, the figures indicate that use can grow quickly after tools become available. They do not establish that agents are already delivering more business value than ordinary chat.

That distinction matters because output tokens measure generated text, not completed tasks, users, time saved, revenue or quality. OpenAI’s Enterprise Signals page describes tokens as an imperfect measure of business value and notes that agentic tasks can require substantially more computation. An agent may read files, plan, write and check its work, generating many more tokens than a short chat response. The 55% figure therefore means agents account for more of the output in these accounts, not that they are involved in most interactions or work.

The report’s comparisons of leading firms also describe activity rather than results. OpenAI defines “frontier firms” as the top 10% by output tokens per active user. It says EU frontier firms produced about four times as many tokens per user as typical EU firms in September, while frontier firms outside the EU produced more than twice as many as the EU frontier. That gap could matter to debates about adoption and access to advanced tools, but token intensity alone does not show productivity or explain why the groups differ.

A July Launch Shapes the Trend

The reported growth period begins in May, before ChatGPT Work launched in July. OpenAI’s chart shows Codex rising from roughly one-fifth of EU output tokens in May to 34% by September 30; ChatGPT Work then contributed 21 percentage points after its launch. The source’s figures suggest the launch accounts for a substantial part of the increase in agentic output, rather than documenting a change independent of a new product.

OpenAI says a “major part” of the small-business user growth followed ChatGPT Work’s introduction. The comparison is between weekly active users in the first week of May and the week ending October 5, so it spans both the product launch and several months of availability. Without absolute user counts, the 8.1-fold growth multiple cannot show how widespread the tools are among EU small businesses or how much the user base changed in total.

OpenAI’s report frames the policy challenge as moving from broad access to deeper use: developing workers’ skills and confidence, and making advanced capabilities more accessible and affordable. It also reports that EU companies make up about 10% of frontier firms worldwide, compared with about 65% in North America. Those estimates use OpenAI’s own customer and activity definitions, and should be read within that scope.

What the Customer Data Cannot Show

OpenAI does not publish country-by-country account or user sample sizes in the material described, making it difficult to judge how representative the national shares are. The company notes that smaller countries such as Cyprus, Estonia and Lithuania have relatively high agentic use within larger firms. A small number of large or heavily agent-oriented customers could influence a country’s result; the report does not quantify that possibility.

The figures also do not establish how many interactions involved agents, what tasks they completed, whether the work was accurate, or whether adoption improved business outcomes. The 8.1-fold small-business increase lacks absolute user totals, and its starting point predates ChatGPT Work’s launch. OpenAI’s data covers its own paying business accounts, not all European businesses or AI providers. The supplied material also does not provide independent verification of the company’s measurements.

Evidence Needed Beyond Token Use

OpenAI presents the report as a case for improving access, worker skills and confidence, but the report does not specify a public timetable for those policy proposals or identify a next measurement date. Further reporting from the company could clarify account counts, country sample sizes and how agent use is distributed across business sizes and sectors.

To determine whether adoption translates into economic gains, readers will need evidence beyond token output: comparable measures of completed work, accuracy, costs and productivity over time. Until such data is available, the report is best treated as a snapshot of OpenAI’s EU business customers and a signal of growing product use, not a measure of agent adoption or business impact across Europe as a whole.

Key Questions

What does OpenAI mean by agents generating 55% of output?

It means Codex and ChatGPT Work produced 55% of output tokens in the covered EU ChatGPT Enterprise and Business accounts by September 30. It does not mean agents handled 55% of users’ tasks or created 55% of business value.

Which products are counted as agentic?

The report counts Codex, OpenAI’s coding agent, and ChatGPT Work, an agent mode launched in July 2026. Standard ChatGPT is counted separately.

What does the 8.1-fold growth figure refer to?

It is the reported increase in weekly active users of Codex or ChatGPT Work among businesses with 200 or fewer users, from the first week of May to the week ending October 5. OpenAI did not provide absolute user totals with the multiple.

Do the country rankings show which EU nations are most ready for AI?

No. They show reported agentic output shares in OpenAI’s customer accounts, and the report does not give country-level sample sizes. They should not be treated as rankings of national AI readiness.
