The U.S. Department of Defense announced the addition of Starshield AI’s Grok Government and OpenAI’s ChatGPT for unclassified military use. The deployment expands the number of AI assistants available through the department’s platform.

The department said users would receive features including deep-thinking reasoning, adaptive reasoning modes identified as automatic, fast, and expert, customizable workspaces, persistent projects, and reusable “playbooks.” The playbooks are intended to capture and distribute institutional knowledge.

The Defense Department identified procurement-market research and supply-chain management for logistics personnel as example use cases for Grok Government.
