Multiple reports say Amazon communicated concerns to U.S. authorities about Anthropic’s latest AI models ahead of a Friday shutdown and access restriction. According to a cited source, Amazon CEO Andy Jassy and other technology companies urged the Trump administration to review Anthropic’s models, including Fable 5 and Mythos 5, citing national security considerations. Following these concerns, the administration orders Anthropic to block foreign nationals from using the models, whether they are inside the United States or abroad. The reports also describe an extraordinary step by Anthropic on June 12, 2026, when it shuts down its latest models globally, framing the action as a response to national security orders from the Trump administration. While the outlets differ slightly in emphasis—some foreground Amazon’s role in prompting the crackdown—the core account is consistent: Amazon and other firms raised warnings, and the administration then directed Anthropic to restrict access to its newest models for foreign users. The articles do not provide additional technical details of the alleged risks or the specific grounds cited by the U.S. order.
