Anthropic Mythos 5 approval has cleared US government review. After weeks of talks with the Trump administration, Anthropic received clearance to resume access to its AI model.
According to a letter from the Commerce Department, the authorization permits Anthropic to issue Mythos 5 to approximately 100 businesses and federal agencies.
Why Anthropic Mythos 5 approval matters
In the letter, US 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 remains unavailable for the time being. The letter went to Anthropic co‑founder Tom Brown, who has assumed responsibility for talks with the administration from CEO Dario Amodei.
Earlier this month, Anthropic shut down access to Fable 5 and Mythos 5 following an export control order from the US government. Specifically, the order cited “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.” Notably, the bans came just days after Anthropic released the two models. The company touted them as the best in various industry metrics and said Fable 5 is its highest‑level public model with “guardrails” to prevent responses in specific high‑risk regions.
The OpenAI factor in focus
This move resembles a similar one from rival OpenAI. Specifically, Sam Altman’s OpenAI announced the launch of GPT‑5.6 Sol, Terra, and Luna on Friday. The company assured that it is abiding by the government’s request to roll out the initial release to “a small group of trusted partners.”
OpenAI also stated in its notice that it has faith in broad access. Furthermore, it plans to offer the new models for general sale in the coming weeks following a preview to government officials before public availability.
Troubled ties with the administration
Meanwhile, the Trump administration’s ties with Anthropic have been troubled. For example, 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. Consequently, the agency designated the company as a supply chain risk. Anthropic has disputed this designation in court, and the lawsuit remains pending.
