Anthropic Fable 5 AI Ban Lifted: US Approves Model

The public can once again access Anthropic’s powerful Fable 5 AI model. This comes weeks after the Commerce Department required the company to disable it due to potential security risks. Access for customers begins Wednesday. Fable 5, part of Anthropic’s Claude family, was taken offline on June 12 along with its sibling, Mythos 5. Senior administration officials had cited severe cybersecurity risks. Commerce Secretary Howard Lutnick informed Anthropic co-founder Tom Brown of the decision to lift export control restrictions. This followed Anthropic's close coordination and cooperation with government officials to address risks. Anthropic agreed to continue collaborating on protocols and standards for its models and to inform the U.S. government of any malicious activity. Lutnick confirmed the lifting of the ban on X, stating they worked closely with Anthropic to analyze and approve Fable 5. He had previously announced that Mythos 5 would be back online for about 100 trusted organizations. Anthropic debuted Fable 5 and Mythos 5 on June 9 as its most powerful systems. Fable 5 included guardrails to prevent it from assisting with certain cybersecurity and biology tasks. This move signals the federal government's evolving approach to regulating AI capabilities.
