Trump Drops Restrictions On Anthropic's Mythos and Fable Models
(Thursday July 02, 2026 @11:00AM (BeauHD)
from the green-light dept.)
The Trump administration has [1]lifted export restrictions that [2]forced Anthropic to shut off public access to its Mythos and Fable models . After weeks of talks, Secretary of Commerce Howard Lutnick said 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." Access is set to begin returning July 1. TechCrunch reports:
> Anthropic had already publicly pledged to do much of this voluntarily, months before the export rule existed. That's part of why cybersecurity experts were [3]skeptical of the restrictions in the first place. To them, the ban looked less like a security fix and more like leverage, a way for the Trump administration to [4]punish Anthropic for its executives' public criticism of how the government, and the president's political opponents, might use the technology.
>
> Mythos was originally made available to a select group of organizations beginning in April to allay concerns about its ability to identify and exploit vulnerabilities in software, while a version called Fable was released to the public in June with additional security guardrails. However, with Asian AI companies [5]beginning to release their own AI models approaching Mythos-level capabilities -- among them Fugu and Tulonfeng -- the US government was under pressure to ease its restrictions on Anthropic to ensure that American AI could compete globally.
>
> Last week, Lutnick cleared Mythos to be [6]released to select customers approved by the White House. OpenAI's latest models were also released to a group of organizations approved by the Trump team, instead of the public. The Trump administration's [7]erratic approach to AI policymaking has left companies across the industry with little clarity about what will govern future model releases. An executive order issued in June that signaled a desire to review models ahead of release was criticized by influential analysts like Dean W. Ball, who recently started a policy position at OpenAI.
