White House Demands Anthropic Make Fable 5 Immune to All Jailbreaks Before Rerelease — Security Experts Say It May Be Technically Impossible

The Trump administration has told Anthropic that restoring public access to Claude Fable 5 — which has been offline since a government directive last week — requires the company to block all possible jailbreaks, a condition that security researchers quoted by Wired say no AI safety team has ever achieved and may be fundamentally impossible. The original shutdown was triggered by a specific circumvention technique identified on a call between Amazon CEO Andy Jassy and administration officials; the new requirement goes far beyond fixing that single flaw. Anthropic's technical staff are in Washington for talks, but no resolution has been reached.
