Anthropic unblocks strongest model Mythos 5 but "for US government use only"! Netizens furious over double standards, Fable 5 continues to be banned.

AI giant Anthropic released its latest announcement today (27th), stating that after half a month of negotiations mediated with the U.S. government, its most powerful cybersecurity model, “Claude Mythos 5,” has been approved to be brought back online. However, access is “limited” to specific organizations responsible for maintaining U.S. critical infrastructure, while the public version, Fable 5, is still seeking approval to be unblocked. The announcement immediately ignited a community-wide public relations disaster: more than a million netizens blasted Anthropic for allegedly staging AI fear, and it ultimately turned into a tool for privileged groups to secure government monopolies on cutting-edge technology.

Dubbed the “cyber nuclear weapon,” the strongest AI model ultimately fell into the hands of only a few institutions. After the storm in which the U.S. government suddenly restricted access on June 12, AI startup giant Anthropic today (27th) for the first time publicly disclosed the latest progress on unblocking its frontier models Claude Mythos 5 and Fable 5. However, the outcome left the broader developer community deeply disappointed.

Since June 12, we’ve been working closely with the US government to restore access to Claude Mythos 5 and Fable 5. Today, the government notified us that Mythos 5, our strongest cybersecurity model, can be redeployed to a set of US organizations that operate and defend critical…

Mythos 5 returns with conditions, while Fable 5 remains blocked

According to a statement Anthropic published on X (formerly Twitter), since June 12 the company has been actively working closely with the U.S. government to find a way to resolve the issue. The official statement said: “Today, the government notified us that our strongest cybersecurity model, Mythos 5, can be redeployed to a group of U.S. organizations that operate and defend critical infrastructure.”

Anthropic emphasized that its team is restoring access rights to these “specific organizations” as quickly as possible. As for the original Fable 5 model that was intended for the public, the official admitted that it still cannot be provided service at this time, and only stated that it will “continue working with the government to expand the scope of access to Mythos 5 and strive to make Fable 5 available to general users again.”

Community backlash erupts: Hype up AI fears only to establish “technological privilege”

This announcement, originally intended to update progress, triggered an epic PR disaster after it was published. As of now, the post has surpassed 1.3 million views, but the comments section is almost entirely filled with anger and scathing criticism. The cryptocurrency and open-source communities are extremely dissatisfied with such a double standard where “Rules for thee but not for me” apply.

Many sharp criticisms pointed out that Anthropic has long been circulating narratives about “AI doomsday” in the market and overemphasizing security risks, successfully triggering panic within Washington and prompting regulatory intervention. However, the end result was not to make the technology safer, but rather to put advanced AI computing power and technology under the control of U.S. military and government agencies and a small privileged class—while ordinary companies and civilians are denied access under the pretext of “safety.”

This incident once again highlights the core contradiction in today’s AI industry: when tech giants wave the banner of “benefiting all of humanity,” they may in fact be helping the state machinery build a technological wall that is difficult to cross.
