The US Department of War launches two additional generative AI tools on its GenAI.mil platform: OpenAI’s ChatGPT Mil and Starshield AI’s Grok for Government. The rollout is announced for Aug. 31 and presented as an expansion of the suite of AI assistants available to defense personnel within the department’s secure enterprise environment.

According to the department’s statements, both offerings are accredited to handle Controlled Unclassified Information at Impact Level 5, meaning they operate under defined security safeguards while remaining accessible for unclassified workloads. ChatGPT Mil is described as supporting document-heavy tasks such as planning, policy, logistics, and administration, with an interface built around chat, files, projects, and custom GPTs, and designed to scale to support over three million personnel.

Grok for Government is described as adding adaptive reasoning, deep-thinking inference, persistent projects, and reusable “playbooks,” with the aim of improving productivity and knowledge continuity while enabling secure collaboration. Sources also note that the department says GenAI.mil has onboarded more than 1.7 million unique users since its launch. While one outlet frames the move as a broad multi-model ecosystem and reduced reliance on a single provider, another highlights the cybersecurity context, referencing earlier warnings about “shadow AI” tools and risks from unapproved model use.
