OpenAI Deploys AI in US Classified Networks With Multi-Layer Safety Guardrails

· Updated

OpenAI reached an agreement with the US Department of War to deploy its AI in classified environments. OpenAI retains full discretion over its safety stack, deploys via cloud, and keeps cleared personnel in the loop, with contractual protections on top of US law.

The company framed this as a higher bar than existing classified AI deals: other labs reduced guardrails and relied primarily on usage policies. OpenAI also publicly stated Anthropic should not be designated as a supply chain risk — a reference to Anthropic's ongoing dispute with the DoW over contract terms.

OpenAI requested the DoW make these same terms available to all AI labs, aiming to establish a shared model for how AI should operate in classified environments.
