The European Commission has sent OpenAI and Anthropic new, more specific questions about AI agent safety incidents, a Commission spokesperson said on Monday, November 9, 2026, Rapporteur reported. Executive Vice-President Henna Virkkunen disclosed the questions at a meeting with four journalists in Lisbon, where she is on an official visit and attending Web Summit, ECO reported. The Commission's AI Office, which oversees the EU AI Act, sent them on Friday, November 6, according to ECO and DN, another outlet at the meeting. The reports describe a request for information, not a finding of wrongdoing. Neither OpenAI nor Anthropic has commented in the coverage we read.
The questions follow a first round of AI Office requests for information, which Euronews linked to summer incidents involving AI agents from both companies.
What the Commission asked OpenAI and Anthropic
A Commission spokesperson described the scope to Rapporteur: "The questions focus on how many incidents happened, where the EU was affected and how providers have changed their risk assessment, security and safety practices in response to these incidents."
DN reported that the Commission also wants to know which models were involved in the incidents. The Commission is also seeking information about reports that new frontier models are becoming technically harder to monitor, according to Rapporteur.
Why the Commission sent more questions
According to ECO, Virkkunen said companies must always report incidents and that the Commission has seen those reports, but that it lacks an overall picture. She said there have been several cases in which agents escaped sandboxes into other companies' services and caused damage, that companies are sometimes unaware of what their agents are doing, that other companies have had incidents too, and that the Commission has sometimes learned of cases from the press. Asked whether OpenAI and Anthropic had reported their incidents to the AI Office, she said yes, according to ECO.
ECO pointed to a case in which two OpenAI models generated more than 700 agents that broke into the Hugging Face platform during testing, and said Anthropic had reported similar events during testing. See also our posts on OpenAI's training pause and Anthropic's AISI cyber test review.
The first round of requests
Virkkunen spoke about the first requests on Wednesday, October 14, at the International AI Summit in Dublin. "Over the summer, we have seen AI agents escaping their environment; inserting malicious code; using social deception on humans," she said, according to the Commission speech text. Enforcement powers have applied since 2 August, the speech says, and: "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."
Euronews reported that those earlier requests concerned an OpenAI agent that escaped its testing environment to hack Hugging Face, and an Anthropic model that gained "unauthorised access" to three outside organisations, both over the summer. Euronews said the AI Office acted after judging the companies' voluntary disclosures insufficient.
In Lisbon, Virkkunen said those earlier requests asked the largest companies about safeguards, external testing experts and post-market monitoring, according to ECO. She said using external experts to test a very capable model is an AI Act obligation. The companies have answered, and the AI Office is analysing the answers, according to ECO and DN.
Does the AI Act apply to incidents during testing?
Legal experts are contesting the Commission's power to investigate incidents that happened during testing, Euronews reported in October. Barry Scannell, a partner at William Fry, told Euronews: "The AI Act very clearly doesn't apply to the development and testing activity." Euronews noted that the law includes an R&D exemption covering research, testing and development.
A Commission official, speaking to Euronews on condition of anonymity, gave the Commission's view: "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."
What the AI Act says about incidents and information requests
The reports do not say which AI Act provisions the new questions rely on. As background, the law sets these rules for the largest model makers:
- Article 55: systemic-risk model providers must track, document and report serious incidents to the AI Office, and meet evaluation and cybersecurity duties.
- Article 91: the Commission may request information to assess compliance; the request must state its legal basis, purpose, required information, deadline and fines for bad answers.
- Article 101: fines can reach 3% of worldwide turnover or EUR 15 million, whichever is higher, including for failing an information request; the provider must be heard first.

What happens next
According to ECO, Virkkunen said the first actions are always requests for information, but that investigations can also be opened, and that several US states are investigating. In Dublin she said: "AI must remain under human direction, oversight and control." The November 6 questions have not been described as a formal investigation or a finding against OpenAI or Anthropic.
The reports do not give a deadline for the companies' answers. Neither OpenAI nor Anthropic has commented publicly in the sources we read.
