Staff at the Department of Homeland Security are no longer allowed to use commercial generative artificial intelligence tools like ChatGPT and Claude , according to a memo sent to employees this month. The move is a reversal of a previous policy — which had conditionally allowed the use of commercial systems — and a pivot toward technology developed in-house. Earlier this month, DHS’s chief information officer, Antoine McCord, sent a memo directing component tech offices to begin “restricting” the use of generative AI systems and pointing employees to internal tools. Older guidance, which the CIO described as “outdated” and “too narrowly” focused on commercial generative AI, was also removed from an online list of IT management directives. The decision comes as federal agencies weigh various pathways toward integrating generative AI into their workflows, a priority of both the Biden and Trump administrations. While some government agencies initially blocked generative AI systems, CIOs have slowly started to develop usage policies. Some agencies, like DHS and the General Services Administration, have now built their own platforms based on commercial technologies, while others have opted to use products like ChatGPT Gov through government cloud systems.
