OpenAI said on February 28, 2026 that it reached an agreement with the Department of War for classified AI deployments, and posted a March 2 update adding explicit domestic-surveillance limitation language. The company highlights cloud-only deployment, retained safety-stack control, and cleared personnel-in-the-loop safeguards.

Anthropic CEO Dario Amodei confirmed in a CBS interview that the company built custom Claude models for the military that are 1-2 generations ahead of consumer versions, deployed on classified cloud infrastructure.

OpenAI said on February 28, 2026 that it reached an agreement with the U.S. Department of War to deploy advanced AI systems in classified environments.
