safety warnings Anthropic issued about its powerful AI models may have led to their shutdown by the U.S. government over national security concerns. The company was ordered to disable Claude Fable 5 and Claude Mythos 5 globally, despite arguing the alleged vulnerabilities are already present in other publicly available AI systems. Anthropic maintains its safeguards are robust and criticizes the decision, warning it could stifle innovation across the AI industry.
The U.S. government ordered Anthropic on Friday to immediately disable global access to its two most powerful AI models, Claude Fable 5 and Claude Mythos 5, citing national security concerns framed as an export control action. Anthropic complied but publicly disputed the move, arguing the underlying issue—a claimed narrow jailbreak of Fable 5 that lets the model identify software flaws—reflects a capability already available in other public models and used routinely for defensive cybersecurity. The company warned that applying such a standard across the industry would effectively halt all new frontier model deployments, a notable clash for a firm that has built its identity around being the safety-focused AI developer ahead of an expected IPO.
