After months of arduous negotiations, the European Commission officially confirmed on Monday that it has reached an agreement with the U.S. artificial intelligence unicorn Anthropic. This highly anticipated AI company will grant the EU access to its most advanced model, "Mythos," marking a significant breakthrough in cybersecurity regulatory cooperation between the two sides.

The Double-Edged Sword of Security Vulnerabilities
As the core of Anthropic's cybersecurity project "Project Glasswing," the Mythos model was first made available to a very limited number of companies in April this year. This model has extremely powerful code auditing capabilities and is adept at accurately identifying unknown security vulnerabilities and architectural weaknesses in software systems.
However, this powerful capability has also raised deep concerns, as it could easily become a destructive weapon that accelerates cybercrime if exploited by malicious hackers. An EU spokesperson for technological sovereignty said that they welcome this progress in access rights and emphasized that the move aims to more clearly assess and understand the potential risks that next-generation AI technologies may bring.
Technological Sovereignty Behind the U.S.-EU Game
According to insiders, due to the U.S. government's general tendency to restrict sharing such powerful models with non-U.S. official institutions to maintain its absolute dominance in the AI field, the EU has significantly increased communication with the U.S. administration over the past week. Previously, in May, the EU had already gained access to the GPT-5.5-Cyber model from OpenAI.
Currently, a new wave of ultra-powerful models is accelerating into the market, and technology regulation has become a common challenge facing the global community. In addition to Anthropic, U.S. authorities have recently also reached agreements with Google DeepMind, Microsoft, and xAI to ensure that the government can conduct safety assessments of these top AI models before they are publicly released.
