Anthropic has suspended access to its most advanced artificial intelligence model following a directive from the United States government. The order, issued yesterday, restricts access both outside of US territory and to foreign nationals within the country. US authorities cited national security concerns as the reason for the action. The move effectively limits who can utilize the cutting-edge AI technology. Details regarding the specific security risks prompting the decision have not been publicly disclosed. This restriction impacts the availability of the model for international researchers and developers. Anthropic has complied with the government’s request, pausing external access to the system.
