Significant progress has been made in the global governance of AI security and geopolitical diplomacy. On Monday, the European Commission officially confirmed that after months of diplomatic efforts and several productive meetings, the U.S. top artificial intelligence unicorn company Anthropic has decided to grant access to its most advanced AI security model, "Mythos," to the EU. This move aims to help the EU better assess and understand the potential cybersecurity risks posed by next-generation cutting-edge large models.

As a core component of Anthropic's cybersecurity project "Project Glasswing," the Mythos model was first made available to a select group of companies in April this year. The model has strong specialized security analysis capabilities, capable of accurately identifying thousands of previously unknown security vulnerabilities and weaknesses in complex software. However, this powerful "double-edged sword" attribute triggered deep concerns from governments, financial institutions, and tech giants upon its release. There is widespread concern that if this technology falls into the hands of malicious actors, it could significantly accelerate cybercrime and create serious cybersecurity threats.

Beneath this battle over access rights, the process has been full of twists and turns. Previously, insiders revealed that due to the extremely high technical secrets and strategic value involved, Anthropic had informed the EU that it needed permission from the U.S. government. In response, the EU has intensified communication with the U.S. administration over the past week. The U.S. government generally opposes sharing such core underlying models with non-U.S. official organizations, aiming to ensure the United States' absolute dominance and technological sovereignty in the global AI field.

Despite these geopolitical technological barriers, the EU continues to accelerate breakthroughs in promoting advanced AI regulation and security collaboration. Prior to this, the EU successfully obtained access to the advanced security model GPT-5.5-Cyber from OpenAI in May this year. At the same time, safety pre-review of large models is becoming a mainstream trend globally. In May this year, U.S. relevant government departments also reached similar agreements with Google DeepMind, Microsoft, and xAI, Musk's company, allowing official entities to conduct comprehensive security and risk assessments of AI models before their public release.

Thomas Regnier, a spokesperson for the EU on technological sovereignty, welcomed this development in a statement, emphasizing that as a new wave of more powerful models accelerates into the market, how to balance technological innovation and cybersecurity has become a serious challenge facing the international community. Currently, the EU is further strengthening dialogue with like-minded partners, including the United States, in an attempt to build more normalized security defenses in the core areas of the global AI value chain.
