US Govt. Approves Anthropic Mythos AI Rollout To Selected Organizations

After weeks of talks with the Trump administration, Anthropic has received U.S. government clearance to resume access to its Mythos 5 artificial intelligence model, the company said in a letter from the Commerce Department.

U.S. Authorized Anthropic Mythos Launch

The authorization is to issue Anthropic’s Mythos 5 to a limited number of approximately 100 businesses and federal agencies. In the letter, U.S. Commerce Secretary Howard Lutnick wrote, “I have determined that appropriate safeguards are in place to permit certain trusted partners to access the Claude Mythos 5 Model.”

However, the approval does not apply to Anthropic’s Fable 5 model, which is still not available for the time being. The letter was sent to Anthropic co-founder Tom Brown, who has said he has assumed responsibility for talks with the administration from CEO Dario Amodei.

Earlier this month, Anthropic shutdown access to Fable 5 and Mythos 5, following an export control order from the U.S. government. The order was based on “national security authorities” and mandated the company to “stop access” by “any foreign national, whether in or outside the United States, including foreign national Anthropic employees,” the company said.

The bans were imposed just days after the two models were also released by Anthropic. It touted them as the best in various industry metrics, and said Fable 5 is its highest level of public model that has “guardrails” to prevent responses in specific high-risk regions.

The OpenAI Factor In Focus

It is a move similar to that of rival OpenAI. Sam Altman’s OpenAI has announced the launch of GPT-5.6 Sol, Terra and Luna on Friday, assuring that it is abiding by the government’s request to roll out the initial release to “a small group of trusted partners.”

The company has stated in its notice that it has faith in broad access. Moreover, it plans to offer the new models for general sale in the coming weeks following a preview to government officials before being made available.

Meanwhile, the Trump administration’s ties with Anthropic have been troubled. The company faced a similar situation earlier this year when it challenged the Department of Defense over its plans to use its AI systems for military purposes, which resulted in the agency’s designation of the company as a supply chain risk. Anthropic has disputed this designation in court and the lawsuit is pending.
