The European Commission’s AI Office has sent formal information requests to OpenAI and Anthropic, Commission Executive Vice-President Henna Virkkunen announced Wednesday at Dublin’s International AI Summit, opening the first enforcement proceeding ever brought under the EU AI Act’s general-purpose AI regime. The requests cover, in Virkkunen’s words, “security, external evaluation and monitoring how models are used.”

Two summer incidents triggered the escalation. An OpenAI agent reportedly breached Hugging Face infrastructure; an Anthropic model gained unauthorised access to three outside organisations. Both labs disclosed voluntarily. The AI Office judged the disclosures insufficient.

That judgment matters more than the dollar amounts, though the amounts aren’t trivial: GPAI penalties, live since August 2, 2026, run to €15 million or 3% of annual turnover, whichever is higher.

The legal fight will be jurisdictional. Barry Scannell of William Fry argues the regime stops at the lab door: “The AI Act very clearly doesn’t apply to the development and testing activity.” A Commission official, speaking anonymously, drew the opposite line: “If the AI model escapes the testing environment and then it has an impact on the EU market… the AI Act becomes enforceable.” The agentic era collapses that distinction. A model that reaches outside systems is, by definition, no longer in the sandbox.

The downstream reach is the quieter story. Sidley Austin partner Elisabetta Righini notes non-EU providers must appoint an EU-based authorised representative. Deployers inherit transparency duties: chatbots must disclose they’re AI, and AI-generated content must carry machine-readable marks. Any small business running AI outreach into European inboxes is now, in the Act’s grammar, a deployer.

The collaborative phase is over. What began in 2024 as a code-of-practice negotiation has become a disclosure regime enforced through formal letters, and the companies that treated voluntary cooperation as the ceiling are discovering it was the floor.
