Anthropic Disables Top-Tier AI Models Following US Foreigner Ban
The company suspended access to Fable 5 and Mythos 5 models after a Trump administration directive cited national security concerns.
US Government Order
Anthropic has disabled customer access to its most advanced artificial intelligence systems, Fable 5 and Mythos 5. The company announced the move on Friday evening, stating it was ordered by the U.S. government to suspend access for all foreign nationals.
The Trump administration issued the directive based on national security grounds. According to Reuters, Anthropic received an export control directive requiring the suspension of these specific models for foreign nationals, though the company noted it was not provided with specific details regarding the order.
Security Concerns and Vulnerabilities
The U.S. government's decision stems from concerns that existing safeguards on the AI models could be bypassed. Specifically, officials believe the technology could be utilized to identify software vulnerabilities.
CNN reported that this broad directive targeting Mythos 5 and Fable 5 represents one of the most far-reaching actions taken by the government in response to the advanced capabilities of AI models. Other reports describe the move as a first for any AI company.
Company Response
Anthropic stated it would "abruptly disable" the affected models for all users following the order to block foreign nationals.
CNN noted that this suspension is part of a series of adverse actions taken by the Trump administration against Anthropic.
