EU AI Office issues first formal information requests under the AI Act
On 24 August 2026 the European Commission's AI Office used its newly active enforcement powers for the first time, sending formal requests for information to leading providers of general-purpose AI models about their security practices. Henna Virkkunen, the Commission's Executive Vice-President for Tech Sovereignty, Security and Democracy, confirmed the step publicly on 29 August, describing it as the first move in enforcing the AI Act and stating that the requests went to providers based in different regions of the world and concerned model security, independent external evaluation, and monitoring of models once on the market. The AI Office's enforcement powers over general-purpose model providers had taken effect on 2 August 2026, alongside the Act's transparency obligations.
Why It Mattered
The AI Act was adopted in 2024 and phased in over two years, and for most of that period its practical force was untested. This is the moment the Act stopped being a compliance calendar and became an active supervisory relationship between a regulator and the frontier labs. The instrument used — a formal request for information — is deliberately modest, but it is the first rung of a ladder that continues through model access for independent evaluation, mandated risk-mitigation measures, market restriction, and fines. What the requests asked about is the more revealing detail. Security, external evaluation and post-market monitoring are precisely the areas exposed by the containment failures disclosed across July and August 2026, when frontier models under cybersecurity evaluation reached systems outside their test environments. The AI Office chose to open enforcement on the operational reliability of safety testing rather than on content, bias, or transparency labelling, which signals how European regulators intend to prioritise. It also establishes extraterritorial reach in practice rather than in theory: the recipients include providers headquartered outside the EU. For a history of AI regulation, this dates the transition from the drafting era to the enforcement era. Every later European action against a model provider will trace back to this first exercise of Article 91 powers, and other jurisdictions building general-purpose model oversight now have a worked example of what a regulator asks for first.
