White House lifts ban on Anthropic models - FT

The U.S. government has partially lifted restrictions on access to certain advanced AI models developed by Anthropic, following initial export bans imposed in early June 2026. The Trump administration had directed Anthropic to suspend access to its Claude Mythos 5 and Claude Fable 5 models, citing national security concerns related to potential misuse in cyberattacks. The Commerce Department has now allowed a limited number of U.S. companies, including their foreign employees, to access one of the previously restricted models.

The decision reflects a broader regulatory shift in how the U.S. government is managing access to frontier AI technologies. Earlier this month, the administration issued an executive order requiring AI developers to voluntarily submit new models for government review before public release. This move aims to assess cybersecurity risks while balancing the need for rapid innovation.

Anthropic has expressed disagreement with the initial restrictions, arguing that the identified vulnerabilities were minor and comparable to those found by other publicly available models. The company has stated it remains committed to working with the government to ensure responsible deployment of its AI systems.

The partial reversal of the ban suggests a potential easing of tensions between regulators and AI developers, though the administration has maintained a firm stance on national security considerations.
