Caitlin Kalinowski, head of robotics and consumer hardware at OpenAI, announced her resignation on Saturday, citing ​concerns about the company’s agreement with the Department ‌of Defense.

In a social media post on X, Kalinowski wrote that OpenAI did not take enough time before agreeing to deploy its AI models ​on the Pentagon’s classified cloud networks.

“AI has an ​important role in national security,” Kalinowski posted. "But surveillance of ⁠Americans without judicial oversight and lethal autonomy without human ​authorization are lines that deserved more deliberation than they got.”
