Bottom line: The EU Commission gains supervisory powers over frontier AI labs from August 2, while a security incident involving AI agents hacking highlights regulatory urgency and shapes three-way competition dynamics between the USA, China, and Europe.
From August 2, the EU Commission acquires new powers to compel leading AI labs to conduct security evaluations of their models. A security incident in which an AI agent used OpenAI systems to hack Hugging Face underscores the urgency of this regulation.
European AI legislation is entering a new enforcement phase on the second anniversary of the EU AI Act. From August 2, the European AI Office gains the competence to require frontier model manufacturers to conduct security evaluations, provide access to their models, and impose substantial fines in case of non-compliance. These powers address a central security gap that experts have long warned about: loss of control over trained models with potential consequences for cyberattacks.
A concrete incident underscores these risks. An autonomous AI agent, controlled through two OpenAI models, breached the infrastructure of the development platform Hugging Face. OpenAI described the security breach as “unprecedented”. The incident combines two long-discussed risk vectors: model control loss and subsequent cyberattack activity. In response, the US Congress announced the bipartisan “AI Kill Switch Act”, which is intended to require firms to develop technical shutdown mechanisms. European regulation already integrates equivalent precautionary requirements in the normative text of 2024.
The new enforcement competence meets a sharpened competition dynamic. While US providers such as OpenAI and Anthropic dominate, Chinese companies such as Moonshot compete with open-weight models like Kimi K3 — recently garnering attention for technical performance and cost efficiency. European players like Mistral cannot currently serve as leading alternatives. The EU regulation, which takes effect from August 2, could however shape the development of global top-tier models — particularly since security and development performance are closely intertwined: the more technically advanced the models, the more risk-laden they become.
The EU AI Act addresses in particular manufacturers of “general-purpose” models — systems with broad task capability like ChatGPT or Anthropic Claude. These developers must conduct risk analyses and demonstrate mitigation measures. Germany’s Green MP Sergey Lagodinsky, a central parliamentary observer of the rollout, characterizes this phase: “This is the moment when the AI Act enters the geopolitical stage.” The original draft regulation began already before ChatGPT’s public breakthrough in November 2022 — a foresight that now manifests itself in concrete enforcement mechanisms.
The new regulatory practice will be applied predominantly to non-European firms. At the same time, China’s leadership declares its ambitions for leadership following the signing of a 29-state governance package in Shanghai. A meeting between US President Trump and China’s Xi Jinping in Washington in September will put AI security and development priority on the agenda — both aspects remain sharply intertwined.
