A Principled Departure
Caitlin Kalinowski, the head of OpenAI's hardware and robotics division, resigned over the weekend in protest of the company's recently finalized agreement with the U.S. Department of Defense. In a statement posted on X, Kalinowski said the deal crossed ethical lines that deserved far more deliberation than they received.
"I resigned from OpenAI. I care deeply about the robotics team and the work we built together. This wasn't an easy call," Kalinowski wrote. "AI has an important role in national security. But surveillance of Americans without judicial oversight and lethal autonomy without human authorization are lines that deserved more deliberation than they got."
Kalinowski's departure marks one of the highest-profile resignations in the AI industry since the Pentagon began aggressively courting Silicon Valley firms for military applications. Her role at OpenAI involved building the hardware that would bring AI models into physical robotic systems, a field that intersects directly with defense applications.
The Pentagon-OpenAI Deal
The agreement that prompted Kalinowski's resignation would embed OpenAI's generative AI systems inside secure Defense Department computing environments. CEO Sam Altman sealed the deal in early March, using language that permits the Pentagon to use OpenAI's models for "all lawful purposes" — a phrase critics argue is deliberately vague enough to encompass domestic mass surveillance.
The backlash was swift. In the days following the announcement, ChatGPT uninstalls surged by 295 percent, according to TechCrunch data. Protesters chalked appeals on sidewalks around OpenAI's San Francisco headquarters, urging employees to consider the implications of the technology they were building.
OpenAI has maintained that it supports responsible use of AI in national security contexts and that all applications must comply with existing law. The company has not directly addressed concerns about domestic surveillance or lethal autonomous systems raised by Kalinowski and other departing staff.
