The White House restricted access to Anthropic’s Mythos 5 and Fable 5 AI models. This decision followed a federal order for Anthropic to revoke access for South Korea-based SK Telecom. U.S. officials cited the telecommunications firm’s alleged ties to China as a primary security concern.
Anthropic reportedly expanded access to its Mythos model without full prior approval. This breach of protocol, combined with reports of security vulnerabilities, damaged the administration’s trust in the company’s ability to safeguard technology.
Anthropic complied with the revocation order before the U.S. implemented a broader ban on all foreign nationals. These cumulative restrictions forced both AI models offline for all users.
