Anthropic disables access to top-tier AI models after US ban on foreign use

Article excerpt

Anthropic has disabled access to its most advanced AI models, Fable 5 and Mythos 5, following a U.S. government order to restrict foreign nationals from using the systems. The ban, issued on national security grounds, represents a significant restriction on the company's global operations and reflects growing U.S. concerns about controlling access to cutting-edge artificial intelligence technology. The move comes as the Biden administration has intensified efforts to limit foreign access to sensitive AI capabilities, though the government has not publicly detailed the specific security threats it aims to address.
