Pentagon to Integrate OpenAI Technology into Classified Network in Landmark Partnership

OpenAI and US Department of Defense Partner on AI Deployment in Classified Network

February 28, 2026

OpenAI has reached a significant agreement with the United States Department of Defense to deploy its artificial intelligence models within the military's classified network. This marks a major milestone in the deepening ties between Silicon Valley and the Pentagon.

Key Provisions and Safeguards

The agreement includes two of OpenAI's core safety principles: prohibitions on domestic mass surveillance and maintaining human responsibility for the use of force, including in autonomous weapons systems. These principles are embedded in the agreement, reflecting the DoD's commitment to safety and responsible AI use. OpenAI will also build technical safeguards to ensure its models behave as intended.

Implementation and Support

To support implementation and ensure safety compliance, OpenAI will deploy field deployment engineers. Its models will operate on cloud networks only, with no on-premise deployment.

Comparison to Anthropic

OpenAI maintains the same "red lines" as rival Anthropic regarding military work, specifically opposition to domestic mass surveillance and fully autonomous weapons use. While the Pentagon has given Anthropic a deadline to drop certain internal guardrails, OpenAI's agreement ensures that its AI systems will be subject to similar constraints.

Broader Deployment and Industry Impact

OpenAI's CEO, Sam Altman, hopes the agreement will help "de-escalate" tensions between the Pentagon and Anthropic. The company is urging the Defense Department to offer the same terms to all AI providers, promoting a more collaborative and responsible approach to AI development and deployment.

Timeline and Context

This agreement follows OpenAI's participation in a Defense Department initiative to develop prototype frontier AI capabilities last summer. With Anthropic's Claude system recently approved for use in classified systems, OpenAI's deployment marks a significant step forward in the Pentagon's efforts to leverage AI for national security challenges.
