Trump Administration Lifts Export Controls on Anthropic's Fable 5 AI Model

The Trump administration lifted export controls on Anthropic's Claude Fable 5 AI model on Tuesday evening. This decision restores public access to the Mythos-class model, which had been pulled for security reasons 18 days prior. Last week, the administration allowed Anthropic to restore access to Mythos 5 for a select group of government-approved organizations. It remains unclear what changes Anthropic made to address concerns from the Commerce Department, particularly regarding access by foreign nationals. Commerce Secretary Howard Lutnick stated that his office worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the U.S. government and strengthen America's leadership in AI. U.S. officials and leading AI companies have expressed concerns about the potential misuse of frontier models for cyberattacks or biological weapons development. Additionally, China is developing its own Mythos competitor while releasing open-weight models that rival Anthropic's offerings. The Trump administration faces an August deadline to create standardized benchmarks for evaluating the security risks of new AI models under a recent executive order.
