The government framed the action as a national-security measure, citing concerns that Fable 5's safeguards could be circumvented through a known jailbreak method.

The incident also underscores mounting friction between AI developers and federal authorities over foreign access, model capabilities, and the government's authority to restrict deployment on security grounds.
