ChatGPT and Grok are coming to the Pentagon’s GenAI.mil platform as the Department of War expands access to specialised AI tools for military personnel and civilian workers, the Pentagon said. The two systems will be available for handling Controlled Unclassified Information (CUI) at Impact Level 5 (IL5). The Department of War announced Monday that the military versions of ChatGPT and Grok will join GenAI.mil, which launched in December with access only to a specialised version of Google’s Gemini. The department said the platform now has 1.7 million users among its 3 million-strong workforce, including military members and civilians. The move follows contracts worth up to $200 million each that the department awarded to OpenAI and Elon Musk’s SpaceXAI for AI tools; Google and Anthropic also received contracts at the time. ChatGPT Mil is being provided through OpenAI for Government. The Pentagon said ChatGPT Mil will keep data within its environment and will not use it to train its models. The Pentagon’s version of Grok, called Starshield AI’s Grok for Government, will provide access to deep thinking, inference, and different reasoning settings, including auto, fast and expert, and can support tasks including market research analysis for acquisition professionals and supply-chain management for logisticians.
