Wed, 01 Jul 2026 Anthropic says US lifts export ban on its advanced AI tools

Fable and Mythos were abruptly suspended in June over concerns that they could be used by hackers.

* Anthropic's AI tools, Claude Fable 5 and Mythos 5, have had their export ban lifted by the US government.
* The ban was imposed just weeks ago over national security concerns that hackers could exploit weaknesses in computer systems using these models.
* Anthropic has agreed to proactively detect and address security risks associated with the models and collaborate on future releases.
* The Commerce Department reserves the right to reconsider its decision if necessary.
* Both Fable 5 and Mythos 5 are advanced AI tools built on the Claude platform, capable of complex tasks independently and identifying vulnerabilities in computer code.
