The Pentagon has given its 3 million civilian and military personnel access to custom military versions of OpenAI’s ChatGPT and Elon Musk’s Grok, while quietly dropping Anthropic’s Claude from its lineup of approved AI tools.
According to TechCrunch, the Department of War launched ChatGPT Mil and Grok for Government, adding them to GenAI.mil, the secure portal the Pentagon set up last year so employees can use commercial AI models without routing sensitive data through consumer channels. The military versions do not include the data collection practices found in consumer AI products.
GenAI.mil originally launched with Google Gemini and has since signed up more than 1.7 million unique users out of the department’s 3 million personnel, the Department of War says.
Claude Gets Cut
Anthropic’s Claude is notably absent. The Trump administration designated Anthropic a supply-chain risk, a call the company is now fighting in court. The dispute reportedly stems from Anthropic’s refusal to grant the Pentagon unrestricted use of its AI tools without certain safety guardrails attached.
ChatGPT Mil comes out of OpenAI’s OpenAI for Government program and, per the War Department, covers chat, files, projects and custom GPTs. It’s built for document-heavy, routine unclassified work such as administrative tasks, logistics, planning and policy, with more features planned down the line.
Grok for Government is branded under SpaceX’s Starshield AI, which runs on a secure satellite network built on Starlink technology. A Department of War press release described the goal plainly:
“Starshield AI’s Grok for Government will provide the warfighter with immediate productivity gains, stronger knowledge continuity and more secure and efficient collaboration.”
Beyond OpenAI and xAI, the Pentagon has also struck AI-related deals with Amazon Web Services, Microsoft, Nvidia and Reflection AI.
OpenAI Pushes Into Medical Records
OpenAI isn’t stopping at the military. The company announced that ChatGPT Health will integrate with Epic’s electronic health record system, which holds data on more than 325 million patients. The integration will let clinicians import patient data and query it with AI, and in some systems ChatGPT will be built directly into EHR workflows.
Clinicians will be able to pull up appointment notes, lab results, medications and specialist documentation, then have the AI summarize that history, flag changes, and prepare for upcoming appointments. In some deployments, doctors can call up ChatGPT directly from inside a patient’s chart to review a case before a visit or build a clinical timeline. OpenAI says the access is read-only — the AI cannot write anything back into a patient’s record.
OpenAI is also rolling out a Healthcare Public Data plug-in pulling from ClinicalTrials.gov, CMS Coverage, RxNorm, DailyMed and PubMed, which could assist with trial eligibility, medication identifiers, coverage policy versions and provider records. Separately, organizations with a Business Associate Agreement will be able to use ChatGPT Work, Codex, apps and connectors within their workspace for clinical workflows that meet compliance requirements.
The moves put OpenAI and xAI at the center of two of the most sensitive data environments in the country — the military and the healthcare system — while Anthropic finds itself locked out of the Pentagon over a fight about safety restrictions on its own technology.
