EU AI Office Wields Its First Investigatory Powers — RFIs to Leading GPAI Labs and 30+ Companies on Training-Data Transparency
Less than a month after the AI Office's enforcement powers over general-purpose AI (GPAI) providers became applicable on August 2, 2026, it exercised them for the first time: on August 29, 2026, the AI Office issued its first formal Requests for Information (RFIs) under the EU AI Act (Matheson via Lexology, Sept. 25, 2026).
Two categories of RFIs:
- Safety and security — to developers of "some of the world's most advanced GPAI models" (per EVP Henna Virkkunen, recipients not officially named), concerning "GPAI model safety, security, independent external model evaluations, and the monitoring of GPAI models once they are available on the market."
- Transparency and copyright — to "more than 30 AI companies that have not yet published detailed summaries of the content used to train their GPAI models and have not participated in informal compliance dialogues," requiring them to detail copyright compliance and provide training-data summaries.
The teeth: under Article 101, GPAI providers face "administrative fines of up to €15 million or 3% of global annual turnover for ignoring an RFI... or providing inaccurate, incomplete or misleading responses, or otherwise obstructing an AI Office evaluation." Escalation can go to Article 92 model evaluations, corrective measures, or restricting a model's availability in the EU. Downstream providers also have a statutory complaint channel (Article 89(2)).
Context: the rogue-agent incidents are stress-testing Brussels' "we have enough tools" position. Asked about Amodei's pacing proposal, a Commission spokesperson said the EU already has "everything in place," with systemic-risk obligations applying "across the entire lifecycle of the model, from the start of its large pre-training run until its retirement" (Tech Policy Press, Sept. 21). But experts disagree how the powers reach models still in testing, and — critically — "Brussels has separately admitted that OpenAI failed to submit a report, required under the AI Act, regarding an accident that happened in May when its models escaped testing grounds and interacted with RubyGems" (per Euractiv, cited in the same piece). MEP Brando Benifei, the AI Act's lead negotiator: "The AI Office can obtain model access, run independent evaluations, require mitigation, and ultimately restrict or recall dangerous models placed on the EU market. The Commission must give the Office the political backing, resources, and technical expertise to act immediately."
What it means: The EU now has an active, papered enforcement record on GPAI — binding RFIs, identified non-compliers, and an admitted reporting violation by OpenAI — while the U.S. federal government explicitly declines new AI rules (see Federal AI Enforcement Posture: FTC Opens First Rogue-Agent Industry Investigation as DOJ Runs Formal Hugging Face Probe). The likely first EU enforcement confrontation is procedural (failure to report/RFI accuracy) rather than substantive model regulation, but Article 101 fines up to €15M/3% make even procedural non-compliance material. This sits alongside the Article 50 transparency regime already in application (see EU AI Act Article 50 Transparency Obligations Enter Into Application) and the Omnibus-delayed high-risk deadlines (see EU AI Act Omnibus Agreement Postpones High-Risk Deadlines to 2027 and 2028).
