White House makes blocking all jailbreaks the bar for restoring Anthropic's Fable 5 and Mythos 5
Trump administration officials told Wired that Anthropic must address the alleged vulnerabilities in Fable 5, the guardrailed version of Mythos 5, before the export controls that took the models offline are lifted. Anthropic has called the concerns overblown and the jailbreak effects minimal, a position it reiterated to the Commerce Department and National Cyber Director Sean Cairncross in a Monday technical meeting, while independent cybersecurity experts say preventing all jailbreaks on frontier models is not possible. Separately, Anthropic employees told the New York Times they feared being singled out, noting that rival firms with comparable models have drawn no similar scrutiny, after the order suspended access to both models for all foreign nationals.
