US Government Allows Rollout of Anthropic's Claude Mythos to 'Trusted' US Institutions

The US Department of Commerce has lifted export controls on Anthropic's powerful AI model, Claude Mythos 5, allowing its rollout to over 100 major US companies and government agencies.

This decision signals an easing of tensions between the Trump administration and Anthropic. Previously, the US government had suspended operation of the Mythos and Fable 5 models over concerns that they could be jailbroken for malicious purposes.

Key details are as follows:

• Trusted partners only: Specific entities designated by the government and their foreign employees can export and transfer the model without a separate license.
• Building a regulatory framework: This move signals the start of a new regulatory regime in which the US government directly controls the rollout of frontier AI models.
• Competitive landscape: Coinciding with OpenAI's recent rollout of GPT-5.6 to government-approved partners, a clear pattern is emerging in which the deployment of major AI models takes place under government approval.

However, the rollout schedule for the Fable 5 model remains unclear, and non-US governments and companies continue to face uncertainty regarding when they will gain access to the model.
