Will the Govt allow Anthropic's Fable 5 back online before July 4?

The U.S. Commerce Department lifted export-control restrictions on Anthropic's Fable 5 model on June 30, 2026, allowing it back online for users starting July 1, roughly two and a half weeks after the government had ordered it offline.

Commerce issued a private directive on June 12 citing national security concerns after a jailbreak was discovered that could prompt Fable 5 to describe or generate code exploiting software vulnerabilities. The order required Anthropic to verify that users were not foreign nationals before granting access; because the company could not perform real-time nationality checks, it took the model offline entirely rather than risk violating the directive.

Over the following weeks, Anthropic built a mitigation it said blocked the jailbreak in about 99 percent of attempts. Commerce Secretary Howard Lutnick notified the company on June 30 that the restrictions were lifted, in exchange for commitments from Anthropic to proactively report security risks and help set safety standards for future models.

The community largely did not anticipate this resolution: only 34 percent predicted the model would return before July 4, while the market resolved yes.
