OpenAI Chief Executive Sam Altman announced Saturday that the company has reached an agreement with the US War Department to deploy its AI models within the authority’s classified networks. The development comes at a time when US President Donald Trump has banned every federal agency from using Anthropic.In a post onHe said, “AI security and the broad distribution of benefits are at the core of our mission. Our two most important security principles are a ban on domestic mass surveillance and humanitarian responsibility for the use of force, including autonomous weapons systems.” DoW agrees with these principles, reflects them in law and policy, and we incorporate them into our agreements.The tech entrepreneur said the company will create technical safeguards to ensure that its models behave in line with DOW requirements. Additionally, FDEs will be deployed to support the models and for security, the systems will run only on cloud networks.Altman said OpenAI urged the US War Department to “offer these same terms to all AI companies, which in our opinion everyone should be willing to accept. We have expressed our strong desire to see things move away from legal and government actions and toward reasonable agreements.”Meanwhile, OpenAI and Amazon also reached a multi-year strategic partnership to accelerate artificial intelligence innovation in enterprises, start-ups, and consumer applications around the world.Under the agreement, Amazon will invest $50 billion in OpenAI. The company said the commitment begins with an upfront payment of $15 billion, with a further $35 billion to be delivered in the coming months once specified conditions are met.The collaboration also includes the joint development of a stateful runtime environment powered by OpenAI’s models, which will be offered through Amazon Bedrock.According to the statement, the stateful developer environment represents the next step in the use of Frontier AI models. They enable systems to seamlessly access resources such as compute, memory, and identity. It comes amid Trump’s orders directing agencies to immediately stop using Anthropic, a Truth Social post calling the company’s leadership “leftwing nut jobs” and heightened tensions between the White House and the Pentagon’s AI suppliers.The standoff has divided Silicon Valley, with Elon Musk publicly supporting the administration, while Sam Altman expressed sympathy for Anthropic’s security concerns, saying he largely trusts the company’s intentions.
