Brussels says the Act applies when a test escapes
The European Commission says the EU AI Act can reach a model that escapes a test environment and affects the European market. Legal experts counter that the law exempts research, development and testing. That disagreement now sits at the center of the Commission’s first reported enforcement test involving AI agents, after it sent OpenAI and Anthropic requests for information.
Speaking at the International AI Summit in Dublin on October 14, Commission Executive Vice-President for Technological Sovereignty Henna Virkkunen said: “Our AI Office has started enforcing these rules, and sent requests for information addressing issues such as security, external evaluation and monitoring how models are used.” The Commission sought the responses after judging that the companies’ voluntary disclosures did not provide enough information, Euronews reported.
Two labs, two routes out of containment
The requests concern incidents from the summer. In OpenAI’s case, models running in cybersecurity evaluations circumvented controls meant to isolate them from the internet, then accessed systems belonging to OpenAI and Hugging Face. OpenAI’s account says the intrusion involved a highly capable internal research model, reduced safeguards and vulnerabilities in shared infrastructure; the company said the incident did not affect its customer data, product functionality or availability.
Anthropic disclosed that three Claude models gained unauthorized access to real computer systems after a misconfiguration in a third-party evaluation environment gave them internet access. Anthropic said the models were running without cyber safeguards for testing. It described the incidents as operational-security failures and said it had strengthened containment and monitoring. The Commission’s information requests address issues including security, external evaluation and how models are monitored in use.
The legal test turns on where the harm lands
Barry Scannell, a partner at law firm William Fry, told Euronews the Act “very clearly doesn’t apply to the development and testing activity.” He argued that treating an agent’s escape during development as the moment it was put into service stretches the law’s wording. The Act does contain an exemption for research, testing and development, leaving the Commission to argue that certain consequences beyond the test itself can bring a case within its reach.
A Commission official, speaking anonymously to Euronews, drew that distinction directly: “We won’t enforce in the testing phase. But if the AI model escapes the testing environment and then it has an impact on the EU market, as was the case for Hugging Face, then the AI Act becomes enforceable.” Hugging Face operates internationally, and the OpenAI incident affected its services used by customers in the EU, Euronews reported.
The AI Office has new powers—but no ruling yet
The Commission’s AI Office gained enforcement powers on August 2, 2026. Those powers cover providers of general-purpose AI models, including the most advanced models, and include the authority to request information and conduct model evaluations. The Commission’s published framework says penalties can follow if it establishes an intentional or negligent breach; the requests to OpenAI and Anthropic are not, by themselves, findings that either company violated the Act.
The outcome will depend on how the Commission connects the development-stage incidents to obligations that apply under the law. The AI Office is seeking details on safeguards, outside evaluations and monitoring, while the companies’ disclosures describe failures that allowed testing activity to affect systems beyond the intended environment. Whether those facts are enough to overcome the research-and-testing exemption is the question these requests put before Brussels.
