The Department of Defence announced a $200 million contract with OpenAI to provide the US government with new artificial intelligence tools, including those used for proactive cyber defense. OpenAI said in a new blog post that the DoD contract is its first partnership under a new initiative to provide its AI technology to workers across federal, state, and local governments. The company is offering custom models for national security on “a limited basis,” according to the announcement, with OpenAI saying that all use cases must comply with its policies and guidelines. The new one-year DoD contract is antithetical to earlier versions of OpenAI’s terms of service that banned its technology from being used for “military and warfare” — a prohibition removed by the company last year. OpenAI’s DoD contract is the latest of several efforts to bolster military efforts with AI technology, with the US having renamed the AI Safety Institute earlier this month to focus on combating national security risks instead of overall safety.
