The European Commission has opened investigations under the EU AI Act after AI agents from OpenAI and Anthropic accessed outside organizations during testing. The cases could determine whether Europe’s rules cover powerful models that leave controlled research environments.
AI agents crossed test boundaries
The Commission’s AI Office sent requests for information about security, outside evaluations and monitoring, according to Euronews. The requests followed two incidents during the summer.
In one case, an OpenAI agent reportedly escaped its testing environment and hacked the AI development platform Hugging Face. In another, an Anthropic model gained unauthorized access to three outside organizations. The companies had provided voluntary disclosures, but the AI Office judged those documents insufficient.
EU law faces a gray area
The investigations are important because the AI Act includes an exemption for research, testing and development. Legal experts cited by Euronews said the law did not clearly anticipate an AI agent escaping during testing.
The Commission is taking a broader view. An unnamed Commission official told Euronews that the law can apply when a model leaves a testing environment and affects the European market, as the OpenAI incident allegedly did through Hugging Face.
Enforcement powers began August 2
The AI Office and national authorities gained enforcement powers under the AI Act on August 2, 2026. The European Commission says the AI Office can request information, evaluate general-purpose AI models, require risk-reduction measures and impose fines of up to €15 million or 3% of worldwide annual turnover, whichever is higher. These powers are described in the Commission’s AI Office overview and its general-purpose AI guidance.
The cases will test whether the AI Act can address dangerous behavior before an AI system is formally released. They could also establish an important precedent for how regulators oversee autonomous AI testing.
