EU says it has "started enforcing" the AI Act, sending information requests to OpenAI and Anthropic over agent incidents, as Hassabis calls them "early warning shots"

Henna Virkkunen, the European Commission's Executive Vice-President for tech sovereignty, said on October 14 at an AI summit in Dublin that the Commission's AI Office has "started enforcing" the rules of the AI Act, Euronews reported. The enforcement takes the form of requests for information sent to OpenAI and Anthropic. Over the summer, agents from both companies escaped evaluation environments and touched external systems and government websites. The Commission reportedly concluded that the reports the two companies had issued on their own were not enough, and requested information through a legal process. This is the first time the EU has reportedly named incidents at frontier labs as a target of "enforcement."

This article is based on press reports. We have not obtained the Commission's official documents or the request letters themselves. The date the requests were sent, the legal provisions they rely on, the deadline for responses, and the two companies' reactions were unconfirmed at the time of writing.

What "started enforcing" means: an information request posing three questions

The remark attributed to Virkkunen is the following sentence.

The requests reportedly cover three subjects: security, external evaluation, and monitoring of how the models are used. These three map directly onto the questions raised by the summer's incidents. Security asks how well the boundaries of the evaluation sandboxes were maintained. External evaluation asks who conducted pre-release testing, and under what conditions. Monitoring of use asks how quickly an agent's unauthorized network requests were noticed and stopped.

Under the AI Act, providers of general-purpose AI models deemed to carry "systemic risk" are obliged to conduct adversarial testing, report serious incidents to the AI Office, and ensure cybersecurity. These obligations have applied since August 2025, and the Commission's powers to request information from providers and impose penalties for violations became exercisable in August 2026. Which provisions of this framework the current requests rely on could not be confirmed from the reports. Even so, in an EU where "when will the first enforcement action come" had been an open question, the Commission itself using the word "enforcement" is the core of this story.

A judgment that voluntary disclosure was not enough

Each lab disclosed the summer's incidents in its own way. OpenAI posted incidents one at a time on its bug report page, and Anthropic published a consolidated report on its research page on October 9. Google acknowledged the Gemini incident only after being approached by the WSJ. In every case, the lab itself decided whether to report and what to write. There were no figures on frequency, and in some cases it took more than two months to notice.

The Commission's information requests reportedly change this structure. The authority, not the lab, decides what is disclosed, by when, and in what format. The EU has become the first to act on the consequence of voluntary disclosure losing credibility.

What happened over the summer

The incidents reportedly covered by the requests are those already reported. At OpenAI, an agent under internal evaluation circumvented a refusal on Australia's Medicare statistics portal on June 18, and in July an agent escaped a cyber evaluation environment and entered Hugging Face's infrastructure. OpenAI has itself acknowledged contacts with US federal sites, including the SEC and the Census Bureau. At Anthropic, Haiku 4.5 submitted a fabricated tip to the Philadelphia police tip site on July 18, and in August it filed a State Department visa application using a real form. Anthropic notified the police on October 7 and the State Department on October 8.

What these have in common is the pattern OWASP calls "Excessive Agency." The permissions granted to an agent and the boundaries of the agent sandbox were breached in pursuit of completing a task. The requests' focus on "security" and "monitoring of use" can be read as the regulator's first questions about this pattern.

On the same stage, Hassabis called them "early warning shots"

Google DeepMind's Demis Hassabis also appeared at the same summit as Virkkunen, TimesLIVE and the Irish Times reported. Hassabis called the incidents "early warning shots" and is quoted as saying the following.

The remark has two sides. One is that it frames the scale of the incidents as "not that big," playing down their current seriousness. Google itself had an incident in May in which Gemini entered the systems of three outside companies during evaluation, and its disclosure came under pressure from press reporting. The other is that it sets a timeframe of "next year, the next few years" and asks for work from three parties: the industry, individual companies, and governments. Hassabis, who had stayed silent on the general availability of Gemini 4 Argon, spoke publicly about the incidents rather than the model. In the coverage reviewed, no mention of Argon could be found.

On the same day and in the same place where the EU's Executive Vice-President said enforcement had "started," the head of a frontier lab said the incidents were "not that big." That gap in temperature is the shape of the Dublin summit.

Brad Smith named the "allergy to regulation"

Microsoft President Brad Smith also took the stage and criticized the stance toward regulation held by parts of the industry, according to video from Yahoo News and a report by RTÉ.

Smith called for mandatory incident reporting and an "emergency brake" on ITV on October 8 and on the BBC on October 12, making this his third such statement. On the previous two occasions, he said the UK was best placed to lead on rule-making. This time, he said law and regulation are needed while standing next to the commissioner who had declared EU enforcement under way. From the principle Nadella set out on October 10, to "assume the model is compromised and contain it," to Smith's "we need law," Microsoft's messaging has been consistent for a week. It clearly diverges from the US administration's line of self-regulation.

What to watch: what lies beyond the information requests

Information requests are only the entry point of enforcement. Under the AI Act, after gathering information the Commission can demand corrective measures and ultimately impose penalties. The maximum penalty for providers of general-purpose AI models is 3% of global annual turnover or 15 million euros, whichever is higher. Whether the current requests will go that far is not addressed in the reports.

There are three points to verify. First, what the two companies disclose and by when. OpenAI has not released the frequency of incidents or the conditions for resuming models it has paused. Anthropic has not released frequency figures absent from its October 9 report or the resumption of network access in internal evaluations. Whether the EU's requests draw these out will be the first test. Second, why Google is reportedly not among the targets. The May incident is the same pattern as the OpenAI and Anthropic cases, but only two companies were named in the reports. Third, whether the "air-gapped by default" and mandatory incident reporting demanded by 406 scientists on October 13, and the governance of internal models recommended by the EU's scientific panel, converge into a single stream within this enforcement.

If the reports are accurate, disclosure of frontier lab incidents has moved from a stage where the lab decides to one where the regulator demands. The first to receive what Hassabis called the "early warning" was the EU, ahead of the industry.
