The United States government has granted Anthropic permission to re-release its advanced artificial intelligence model, Mythos 5, to a select group of trusted American cybersecurity firms. The announcement was made by Anthropic on Friday.
Restricted Access for Cybersecurity Firms
Anthropic stated that the government notified them of the authorization to redeploy Mythos 5, described as their strongest cybersecurity model, to U.S. organizations responsible for operating and defending critical infrastructure. The company indicated it is moving quickly to restore access for these entities and continues to collaborate with the government on expanding access to Mythos 5 and making their Fable 5 model available for general use once more.
This development occurs two weeks after the Trump administration had previously blocked access to Mythos 5. Anthropic has experienced a challenging relationship with the Trump administration in recent months.
Background of the AI Model Restrictions
Anthropic had abruptly withdrawn its most advanced AI models, Mythos 5 and Fable 5, from all users following a government order on June 12 that restricted their release. The Trump administration cited concerns that powerful AI systems could be exploited by military intelligence users in countries like China and Russia, potentially leading to an aggressive approach to the oversight of releases for frontier models from companies such as Anthropic and its competitor, OpenAI.
The Trump administration’s stringent control measures against Anthropic faced accusations of government overreach.
Concerns Over AI Access and Vetting
Details regarding the government’s vetting process for organizations and the specific criteria for granting access to Mythos 5 have not been disclosed by the Trump administration. OpenAI CEO Sam Altman expressed reservations about the government’s role in selecting customers for top AI models, writing on X that while extensive safety testing is valuable, he dislikes the idea of the government choosing who gains access.
A source familiar with the new directive informed Reuters that over 100 companies and institutions are expected to gain access to Mythos 5, including numerous Fortune 500 companies. The source requested anonymity.
