The U.S. government ordered Anthropic to suspend access to its Fable 5 and Mythos 5 AI models for all foreign nationals. This directive followed national security concerns raised three days after the models' launch.
Anthropic disabled the models for all users to ensure compliance. The company stated the government's action stems from a report of a narrow potential jailbreak.
Anthropic disputed the severity of the finding. The company argued that similar capabilities exist in other public models and warned that this standard could halt most new AI deployments.
