The U.S. government imposed export controls on Anthropic's Fable 5 and Mythos 5 models on June 12, forcing the company to restrict access to foreign nationals.
Anthropic responded by broadly disabling access to the models after determining it could not readily restrict usage based on nationality alone. Public reports indicate the move was driven by concerns that users could bypass safeguards in Fable 5 through prompts as simple as asking the model to "fix this code."
While Anthropic characterized the issue as a limited vulnerability that was not unique to its models, administration officials viewed the capability as a national security concern, arguing that it could be used to identify software vulnerabilities at scale.
