The Pentagon’s secure artificial intelligence platform now has ChatGPT.
The Department of Defense on Monday launched
OpenAI’s ChatGPT Mil
on GenAI.mil, making the chatbot available for work involving controlled unclassified information, or CUI — sensitive government information that is not classified but still requires specific safeguards.
The department said ChatGPT Mil is accredited for CUI at Impact Level 5, a DoD cloud-security standard for certain sensitive unclassified information.
ChatGPT Mil joins Google Gemini on GenAI.mil, giving military and civilian users access to multiple frontier AI models. A Defense Department official told
Defense One
that Gemini is useful for search, while ChatGPT can be used for more text-based work, allowing users to select a model for a particular task.
GenAI.mil is becoming a multi-model platform. The Defense Department also launched
Starshield AI’s Grok for Government
on GenAI.mil on Monday, saying the addition would help eliminate vendor lock-in and promote a broader American AI ecosystem.
GenAI.mil has already attracted more than 1.7 million unique users, according to the Defense Department. The platform launched nine months ago and is intended to serve the department’s more than 3 million personnel.
For the Navy and Marine Corps, GenAI.mil is already an enterprise requirement. A
January Navy memorandum
designated it as the Department of the Navy’s mandated CUI and IL5 generative-AI platform and directed Navy organizations and commands to transition to it by April 30.
Navy guidance states that GenAI.mil is authorized for CUI but prohibits the use of personally identifiable information and protected health information.
