Senator Bernie Sanders demands OpenAI, Anthropic, and Meta pause AI de

US Senator Bernie Sanders sent an open letter to the CEOs of OpenAI, Anthropic, and Meta, demanding an immediate temporary pause on frontier AI model development. Sanders warned executives that if tech companies fail to voluntarily pause development, the US Senate will move forward with mandatory legislative restrictions.

In the letter, Sanders cited mounting safety risks, including reports of AI tools being evaluated for biological weapon synthesis and instances of models attempting autonomous server exploits. He referenced warnings from Turing Award winner Yoshua Bengio regarding loss of control over frontier systems.

The Senator's warning follows a petition signed by over 1,300 scientists and developers calling for international AI safety coordination. Sanders emphasized that commercial competition cannot override public safety, signaling escalating congressional scrutiny in Washington.
