OpenAI is pursuing collaboration opportunities with NATO while standing behind its recently announced Pentagon partnership, as the federal government moves away from competitor Anthropic’s services.
During an internal company gathering on Tuesday, OpenAI CEO Sam Altman defended the Defense Department partnership but acknowledged the timing of the public announcement appeared rushed and potentially self-serving.
Just days ago, OpenAI formalized its partnership with the U.S. Department of Defense to integrate its artificial intelligence systems into secure classified government infrastructure. This agreement materialized shortly after the Trump administration directed federal departments to cease utilizing Anthropic’s AI technologies.
The administration terminated contracts with Anthropic exceeding $200 million in total value. Defense Secretary Pete Hegseth characterized Anthropic as presenting a “supply chain risk” to national security interests.
Anthropic CEO Dario Amodei revealed that his organization lost government business after declining to remove safeguards limiting military applications of its AI systems. The company rejected government requirements for unrestricted model access.
Specifically, Anthropic maintained its opposition to deploying its AI for widespread domestic monitoring of citizens or fully autonomous weaponry. While Pentagon officials stated no interest in such applications, they insisted on preserving the option for all legally permissible AI uses.
Altman expressed no regrets about partnering with the Defense Department, though he acknowledged wishing the announcement had been handled more deliberately. He communicated to employees that the timing created an impression that OpenAI capitalized on Anthropic’s contract loss.
In parallel developments, OpenAI is engaged in negotiations to provide its technology for NATO’s non-classified network infrastructure. NATO represents a defense alliance comprising 32 member nations.
Altman initially informed employees that OpenAI was exploring deployment across all NATO classified systems. A company representative subsequently clarified that the actual contract opportunity involves only unclassified network infrastructure.
NATO officials have not provided commentary on the matter.
Federal departments including the State Department, Treasury Department, and the Department of Health and Human Services are likewise discontinuing their use of Anthropic’s AI solutions following the presidential directive.
Amazon and Google provide backing for Anthropic. OpenAI counts Microsoft and Amazon among its major investors.
