June 18 - Anthropic has continued to allow some of the organizations it picked early to test the Mythos AI system to use a preview build, even as a U.S. government order prompted the complete shutdown of other versions of the model. The preview environment, provided under Anthropic's Glasswing program, was restricted to about 200 organizations after Mythos flagged thousands of software vulnerabilities.
Anthropic initially released a less capable public variant of Mythos, but that version was later disabled in response to Washington's export control directives, which suspended access to the model for all foreign nationals on national security grounds. Despite that suspension, several firms that had been part of the early Glasswing test cohort have retained their preview access.
Security-focused companies Dragos and Cisco Systems confirmed they continue to have access to the Mythos Preview. It remains unclear how Anthropic is deciding which Glasswing members keep access and which do not.
Company representatives at Anthropic, Cisco and Dragos were not immediately available for comment outside business hours. Similarly, the European cybersecurity agency Enisa, which had been invited to join Glasswing before the U.S. government order was issued, was told on Friday that it would no longer be granted access. Enisa was also not immediately available for comment outside business hours.
The episode follows a widening rift between Anthropic and the U.S. government earlier this year, when the company declined requests to permit the U.S. military to use its AI models for domestic surveillance and for fully autonomous weapons systems. That breakdown in relations is part of the broader context surrounding the decision to restrict certain Mythos versions.
The selective continuation of Mythos Preview access raises questions among industry observers about consistency of enforcement and about the mechanics Anthropic is using to vet and authorize individual members of its Glasswing program. For now, the company appears to be maintaining a limited, invite-only preview for some partners while complying with directives that remove broader foreign-national access to publicly released builds.
