Caitlin Kalinowski, who oversaw hardware development at OpenAI, announced her resignation on Saturday, raising concerns about the company’s recent agreement with the Department of Defence.
Concerns Over Oversight and Ethics
In a post on X (formerly Twitter), Kalinowski stated that OpenAI did not take sufficient time before agreeing to deploy its AI models on the Pentagon’s classified cloud networks. She wrote:
“AI has an important role in national security. But surveillance of Americans without judicial oversight and lethal autonomy without human authorisation are lines that deserved more deliberation than they got.”
Kalinowski emphasized that her decision was primarily a governance concern, noting that such sensitive decisions should not be rushed. While expressing “deep respect” for OpenAI CEO Sam Altman and the team, she criticized the company for announcing the deal “without the guardrails defined.”

OpenAI’s Response
OpenAI responded by saying the Pentagon deal includes additional safeguards to ensure responsible use. The company reaffirmed that its “red lines” prohibit the use of its technology in domestic surveillance or autonomous weapons systems. A spokesperson added:
“We recognise that people have strong views about these issues and we will continue to engage in discussion with employees, government, civil society, and communities around the world.”
Kalinowski’s Background
Kalinowski joined OpenAI in 2024 after leading augmented reality hardware development at Meta Platforms. Her resignation highlights growing internal debate in AI companies over ethical use, governance, and the role of AI in defense applications.
Her departure underscores the tension between rapid technological deployment and the need for careful oversight in areas with significant national security and ethical implications.
