Anthropic Disables AI Models After US Export Order

Anthropic has abruptly disabled its most advanced AI models, Fable and Mythos, for all users. This action follows a US government order to block access for foreign nationals. The Department of Commerce imposed export controls after Amazon researchers reported a potential vulnerability in the Fable model. Amazon, a major investor in Anthropic, shared this finding directly with the US government. What's interesting is that this block happened just days after Fable was made widely available to customers. Anthropic had previously highlighted Mythos's advanced capabilities, warning of its potential for hacking critical infrastructure. Anthropic disputes the danger of the reported vulnerability, stating it was not a universal jailbreak and only identified minor, known issues. The company claims the level of capability displayed is widely available from other models. However, the US government deemed the model a national security risk. The Commerce Department's directive means Anthropic employees who are not US nationals also lose access. This move could impact how other advanced AI models are deployed in the future.
