Anthropic, a leading AI developer, abruptly disabled access to its Fable 5 and Mythos 5 models Friday night in response to a directive from the U.S. Commerce Department. The move comes as part of broader export control measures aimed at preventing these advanced AI systems from being used outside the United States.
The directive follows concerns raised by the Trump administration regarding potential vulnerabilities in the models' safeguards. Reports indicated that the models' classifier-based protections could be bypassed, raising alarms about their potential misuse in fields such as cybersecurity, chemistry, and biology.
'The only way for us to ensure compliance with the government order is to disable Fable 5 and Mythos 5 for all customers,' Anthropic stated in a message posted Friday night.
The administration has requested a pause in the release of these models to allow time for strengthening the national security apparatus. Officials estimate that the necessary safeguards could be implemented within weeks.
While access to other Anthropic models remains unaffected, the shutdown underscores the growing emphasis on protecting American technological advancements from foreign exploitation. The move aligns with broader efforts to prioritize national security and maintain U.S. dominance in critical AI sectors.
This decision highlights the administration’s commitment to ensuring that cutting-edge technologies remain securely within U.S. borders, safeguarding both economic and strategic interests.
