U.S. Government Permits Anthropic to Release Claude Mythos 5 AI Model
On Friday, Anthropic announced that the U.S. government has permitted the release of its advanced Claude Mythos 5 artificial intelligence model to a select group of trusted organizations.
This decision partially overturns a suspension enacted two weeks prior, which was motivated by national security apprehensions, as reported by News.Az, citing Reuters.
Access to Mythos 5 will now be granted to over 100 entities, including several members of the Fortune 500, according to a source who wishes to remain anonymous due to the sensitive nature of the information.
Heightened fears regarding the potential misuse of advanced AI technologies by military and intelligence operatives in nations such as China and Russia have prompted a more stringent regulatory approach from the Trump administration towards the distribution of Anthropic’s and rival OpenAI’s top-tier models.
Earlier that same day, OpenAI disclosed it would postpone the public launch of GPT-5.6 at the behest of the U.S. government, thereby restricting access to a limited group of authorized partners, whose identities have been communicated to the authorities.
Previously, Anthropic had suspended access to its most sophisticated AI models—Mythos 5 and Fable 5—following the government’s export control order issued on June 12.
In a statement released on Friday, Anthropic remarked, “Today, the government informed us that Mythos 5, our most robust cybersecurity model, can be redeployed to a set of U.S. organizations responsible for operating and safeguarding critical infrastructure.”
“We are expediting the restoration of access for these organizations, while also collaborating with the government to broaden accessibility to Mythos 5 and reintroduce Fable 5 for general use,” the company further elaborated.
The selection process undertaken by the government to determine which companies gain access to Mythos 5 has faced scrutiny.
- John Coleman, legislative counsel for the Foundation for Individual Rights and Expression, articulated concerns over the lack of transparency: “No one knows how these companies are picked and why everyone else is excluded.”
- He cautioned that this concentration of power could be problematic, questioning the adherence to rule of law.
OpenAI’s CEO, Sam Altman, voiced similar concerns regarding governmental influence over access to advanced AI models in a post on X, stating, “Extensive safety testing is not a bad idea. I just don’t like the idea of the government picking the customers.”
Experts have warned that the potential misuse of Mythos models could lead to an escalation in sophisticated cyber threats, particularly in sectors like banking that rely on complex, interwoven, and often outdated technological frameworks.
A correspondence from U.S. Commerce Secretary Howard Lutnick to Anthropic noted “significant progress” in the company’s collaboration with the government to address risks associated with the Covered Models.

However, it remains unclear what specific safeguards have been enacted. Earlier this month, Anthropic acknowledged the government’s concerns regarding a purported means to circumvent a safeguard designed to prevent Fable 5 from identifying software vulnerabilities.
