EU Seeks U.S. Talks on Mythos AI Access as 70-User Expansion Drew Security Pushback
9 articles · Updated · CNBC · May 29
The EU is moving to intensify talks with the U.S. over access to the most advanced AI models, including systems with cyber capabilities, after Anthropic did not grant the bloc preview access to Mythos.
Anthropic told the Commission it first needed U.S. administration permission, according to a person familiar with the discussions, reflecting Washington's broader resistance to sharing the model with non-U.S. governments.
Security fears are driving the dispute: Mythos triggered alarm over AI-powered cyberattacks, and the White House had already opposed Anthropic's proposal to expand access to roughly 70 additional companies and organizations.
The U.S. says it is working closely with AI labs to balance innovation and safety while preserving its lead over China; Anthropic CEO Dario Amodei recently warned of a 6- to 12-month window to fix vulnerabilities the model exposed.
Is the U.S. strategy of restricting AI access inadvertently accelerating China's path to technological self-sufficiency?

Claude Mythos Access Crisis: How Anthropic’s AI Exclusion Threatens EU Cybersecurity in 2026
Overview
As of May 2026, the European Union is urgently seeking access to Anthropic's advanced AI model, Claude Mythos, a powerful vulnerability detector currently limited to select North American entities. This push comes amid rising concerns about Europe's cybersecurity readiness and the rapid evolution of offensive AI threats. However, Anthropic, as a private American company, has no obligation to share access, leaving the EU with only persuasion, regulatory pressure, and diplomacy as leverage. The European Central Bank has responded by demanding stronger cybersecurity measures from banks, but without Mythos, European institutions face a significant disadvantage in defending against advanced cyber risks.
