Trump administration greenlights Anthropic's Mythos 5 for over 100 US organizations; talks continue on 'Fable 5'

The US government has lifted its block on Anthropic's powerful Claude Mythos 5 AI model, allowing the company to release it to over 100 US institutions including major companies and government agencies. The move marks a significant de-escalation in tensions between the Trump administration and the AI lab, following export controls imposed two weeks ago, according to Semafor. Commerce Secretary Howard Lutnick informed Anthropic in a letter that the decision was made because "appropriate safeguards are in place," Wired reported. The easing followed weeks of negotiations between the White House and Anthropic, during which Amazon and other companies had warned of the consequences of shutting down the model and its cousin Fable 5, Semafor noted. While Mythos 5 has been reinstated for select organizations, the public-facing version, Fable 5, remains in limbo with no clear timeline for rollout, The Verge reported. Hacker News added that sources indicate talks about Fable 5 are ongoing, suggesting the partial resolution may not be the final word. The reinstatement represents a significant pivot in the administration's approach to AI oversight, with the government now granting access to a broader set of organizations than originally blocked. The outcome underscores the high-stakes balancing act between national security concerns and the economic interests of major tech companies that rely on Anthropic's models.
