The United States government issued an export control directive on a Friday night to suspend access to Anthropic's Fable 5 and Mythos 5 models for all foreign nationals.
In response to a U.S. government export control directive, Anthropic took its Fable 5 and Mythos 5 models offline entirely.
A highly credible trusted partner of both Anthropic and the US government, later identified as Amazon, discovered and reported a jailbreak of the guardrails on the Fable 5 model.
According to David Sachs, the White House administration asked Anthropic CEO Dario Amadei to either fix the reported jailbreak in Fable 5 or take the model offline, a request which Amadei refused.
Anthropic was contacted by government officials at 1:00 PM on a Friday and given 90 minutes to take down its Fable and Mythos models due to a 'national security threat'.
The Wall Street Journal reported that the decision to shut down Fable 5 was made after conversations between Amazon CEO Andy Jassy and key officials, including Treasury Secretary Scott Bessant.
According to cybersecurity expert Andrew Morris, Amazon researchers had not presented evidence that they were able to get Fable 5 to produce functional exploit code, which is blocked by its guardrails.
Key administration figures leading the meeting where the decision was made to shut down Fable 5 included Treasury Secretary Scott Bessant, White House Chief of Staff Susie Wiles, and White House Cyber Director Sean Cairncross.
President Trump signed off on the export control action against Anthropic despite having reservations about its potential to hinder innovation.
The publication Semaphore reported that the White House's export controls on Mythos were partly due to suspicions that a China-linked group had accessed the model.
RSI Senior Fellow Adam Terrier argues that the Trump administration's action against Anthropic represents a 'significant escalation in the politicization of AI and centralization of control over advanced computation' in the U.S.
Anthropic dispatched senior technical staff, including Nicholas Carlini, Logan Graham, and David Orr, to Washington D.C. to meet with government security experts and de-escalate the conflict.
