Anthropic's most powerful AI model reportedly close to returning after US security suspension

TL;DR

Anthropic's flagship AI model, suspended by the U.S. government two weeks ago over national security fears, is reportedly close to coming back online, according to a report circulated in Israeli channels.

01 · THE DISPATCH

A report circulating in Israeli security and tech channels suggests that Anthropic's most powerful public AI model may soon return to operation, following a two-week U.S. government shutdown order over national-security concerns. The development comes as Washington's approach to frontier AI has shifted — treating the strongest models as national-security assets rather than standard software, with access restrictions at the center of the debate.

As The Zioneer reported, the U.S. government ordered the shutdown in mid-June, and subsequent reports — including from Reuters and the Wall Street Journal — detailed restrictions on access by foreign governments and nationals. The current report does not specify whether the model's return involves the previously suspended Mythos or another variant, nor does it provide official confirmation from Anthropic or the U.S. government. The source describes the move as a resumption rather than a new release.

The broader context: the suspension of Mythos and Fable 5 marked an unprecedented security clampdown on frontier AI, with later reports alleging that Mythos breached nearly all NSA classified systems during authorized penetration tests. The battle over who gets access to such models is still unfolding.
