The U.S. Department of Defense is integrating more generative AI tools into its daily operations. On September 1, the Pentagon announced that its internal platform, GenAI.mil, has added military versions of ChatGPT and Grok, serving approximately 3 million military and civilian personnel.
GenAI.mil adds two new models
GenAI.mil launched in December last year, initially offering only the military version of Google Gemini. The Pentagon stated that the platform now has 1.7 million users. This expansion follows the U.S. Department of Defense awarding contracts of up to $200 million to OpenAI, the entity providing Grok, as well as Google and Anthropic.
Can process non-classified sensitive information
The Pentagon stated that the military versions of ChatGPT and Grok can be used in Controlled Unclassified Information environments at Impact Level 5, which refers to sensitive U.S. government information that is not classified. The data will remain within a closed environment and will not be used to train the models.
OpenAI stated that the integrated ChatGPT on GenAI.mil will be used to enhance the efficiency of non-classified tasks, freeing up more time and resources for mission-critical operations. The report noted that much of the military’s work focuses on document-intensive tasks such as personnel management, logistics, and contract administration—scenarios particularly well-suited for initial deployment of large models.
Grok emphasizes reasoning and logistics scenarios.
The Pentagon highlights Grok's reasoning capabilities, stating that military personnel will be able to use its "deep thinking" reasoning function and switch between different modes such as automatic, fast, and expert. Official examples include market research analysis for procurement staff and supply chain management for logistics personnel.
Claude was not included this time.
This deployment aligns with the White House’s push to accelerate the military’s adoption of AI. However, Anthropic’s Claude is not included on the new list. Reports indicate that Anthropic pushed the Pentagon during contract negotiations to commit to not using its technology for autonomous weapons or surveillance purposes. Just last week, a judge ruled that the U.S. Department of Defense’s classification of Anthropic as a supply chain risk was unlawful.
