Amazon CEO Andy Jassy's discussions with U.S. officials, including Treasury Secretary Scott Bessent, directly led to the Trump administration's decision to halt all foreign use of Anthropic's most capable AI models, specifically Fable 5, due to identified security vulnerabilities.
Amazon researchers demonstrated Fable 5's ability to provide information aiding cyberattacks, which Jassy reported to officials, according to people familiar with the matter. The administration, which had long felt Anthropic could not be trusted with security risks, acted swiftly.
Officials asked Anthropic to fix the vulnerabilities or take down the model, ultimately deciding to prevent foreign governments, companies, and individuals from accessing the tool. President Trump signed off on the action despite reservations about hindering innovation, a senior White House official said.
Anthropic, a leader in America's AI race and a significant Amazon investment partner (Amazon supplies chips and invested $5 billion), stated the flagged vulnerabilities are basic and comparable to those in other publicly available models. The article notes that all use, domestic and foreign, has been halted because there is no good way to distinguish users.
