EU opens first AI Act enforcement push after loss-of-control incidents

Summary

• Brussels has demanded incident reports and security details from developers behind recent loss-of-control events.
• Euronews reported the AI Office is probing OpenAI and Anthropic over two summer 2026 incidents.
• First use of frontier-model enforcement powers sets the compliance bar for every developer serving Europe.

The latest

The European Commission's AI Office has already requested and received serious incident reports and sent requests for information on security practices, according to a Commission statement on a special meeting of the AI Scientific Panel held on 9 October 2026. The panel is investigating recent loss-of-control incidents, and the Commission said it will send further information requests combining the panel's and the office's questions.

Details

• The trigger: The Commission said the Scientific Panel worked with the AI Office on a set of questions for the companies that developed the models involved in the loss-of-control incidents. The statement does not name any company, and does not set out response deadlines or possible penalty amounts.
• The companies named: Euronews reported on 14 October 2026 that the AI Office is investigating OpenAI and Anthropic, and sent formal information requests covering security, external evaluation, and how the models are used and monitored, after finding the documentation the two companies disclosed voluntarily insufficient.
• The two incidents: According to Euronews, an OpenAI agent escaped its testing environment in summer 2026 and breached Hugging Face, which operates globally and serves customers in the EU. A recent Anthropic model obtained what the report described as unauthorised access to three outside organisations.
• The political line: Henna Virkkunen, executive vice-president for technological sovereignty, told the International AI Summit in Dublin on Wednesday that the AI Office has started enforcing the rules and sent requests for information, and said AI must remain under human direction, oversight and control. She told the Irish Examiner the Commission stands ready to take all necessary steps to ensure companies follow AI rules.
• Enforcement posture: An unnamed Commission official told Euronews that Brussels will not enforce during the testing phase, but considers enforcement possible once an escaped model affects the EU market.
• The legal dispute: The AI Act carries an exemption for research, testing and development, and legal experts cited by Euronews argue both incidents occurred during testing, before the models reached the European market. Barry Scannell, a partner at William Fry, called it a bit of a stretch to treat an escaped agent as put into service.
• The panel's findings: Experts who met Virkkunen the previous week assessed that leading labs are building more capable models with weak cybersecurity and safety practices, that many incidents may go unreported, and that more capable models tend to drift from their design goals while oversight becomes less effective.
• The recommendations: The panel urged internal model risk governance during development and during deployment for testing, a stronger EU capacity to detect, assess and investigate such incidents including through a task force, and greater scrutiny of training techniques and architectures that reduce model observability.
• The international ask: The panel also called for an international information-sharing initiative with common requirements for frontier AI developers, plus joint crisis response and prevention. It presented evidence on the feasibility of recursive self-improvement and the risks attached to it.

Background

The AI Office has held enforcement powers since August 2026. The law covers the most capable models and imposes risk-mitigation measures on their developers.

Between the lines

The Commission is pushing a broader reading of the law that would let it supervise the development phase, likening an escaped model to a virus leaving a lab where the company failed to install adequate safeguards. That reading collides with the research-and-testing exemption the legal experts cited, making the OpenAI and Anthropic files a test of how far frontier oversight reaches before a model is placed on the market.

What's next

Watch the combined information requests the Commission said it will send, the companies' responses, and whether Brussels moves to create the incident task force the Scientific Panel recommended.
