The United States has rescinded a prior requirement for Anthropic to obtain a license before exporting its Mythos and Fable models internationally. This mandate had effectively blocked public access to what are widely regarded as the most advanced artificial intelligence models released to date.
The AI research lab announced its intention to commence the restoration of access to these models starting Wednesday, July 1.
Previously, on June 12, the U.S. government had classified these products as export-restricted technologies, prohibiting their availability to foreign nationals without specific authorization. The extensive scale of Anthropic's operations made compliance with this regulation impractical, compelling the company to entirely cease public access to the models.
Following several weeks of discussions, Secretary of Commerce Howard Lutnick confirmed that Anthropic “has agreed to proactively detect and address security risks associated with the models; to work diligently with the U.S. government on protocols and standards and releases for Mythos, Fable and future models; and to inform the US government of any malicious activity.”
It is noteworthy that Anthropic had already publicly committed to many of these actions voluntarily, months before the export restriction was even implemented. This context contributed to cybersecurity experts' initial skepticism regarding the necessity of these restrictions. To many, the ban appeared less like a genuine security enhancement and more as a form of leverage, potentially used by the Trump administration to penalize Anthropic executives for their public critiques concerning the potential misuse of AI technology by the government and the president's political adversaries.
Mythos was initially made available to a select cohort of organizations in April, a move designed to mitigate concerns regarding its capacity to identify and exploit software vulnerabilities. A variant named Fable was subsequently released to the general public in June, incorporating additional security safeguards.
However, the emergence of Asian AI companies, such as Fugu and Tulonfeng, releasing their own AI models with capabilities approaching those of Mythos, placed considerable pressure on the U.S. government. This competitive landscape necessitated an easing of restrictions on Anthropic to ensure the global competitiveness of American AI innovation.
Just last week, Secretary Lutnick had granted approval for Mythos to be released to a curated list of customers sanctioned by the White House. Similarly, OpenAI's most recent models were also made available to a specific group of organizations approved by the Trump administration, rather than to the broader public.
The Trump administration's inconsistent approach to AI policymaking has created significant ambiguity for companies across the industry regarding the guidelines for future model releases. An executive order issued in June, which indicated a desire for pre-release review of AI models, drew criticism from influential analysts such as Dean W. Ball, who recently assumed a policy role at OpenAI.
