The Pentagon is giving 3 million military and civilian workers access to ChatGPT and Grok through a secure AI platform built for ‘warfighter needs’

American service members will now have access to military versions of ChatGPT and Grok as the Pentagon tries to incorporate more AI into its daily workflows.

The Department of War said in a pair of announcements on Monday that the two services will be incorporated into its bespoke AI platform GenAI.mil, which launched in December and originally offered access only to a specialized military version of Google’s Gemini.

The department said GenAI.mil already counts 1.7 million of the Department of War’s 3 million-strong workforce, which includes both military members and civilians.

The department’s Monday announcement comes after it awarded OpenAI and Elon Musk’s SpaceXAI, which runs Grok, defense contracts worth up to $200 million each to provide the department with AI tools.

It also awarded contracts at the time to Google and Anthropic.

The military version of ChatGPT, dubbed ChatGPT Mil, is part of OpenAI for Government, an initiative launched last summer meant to bring the company’s AI products to government workers.

“ChatGPT on GenAI.mil will make unclassified work throughout the Department more efficient, freeing up time and resources so DoW personnel can focus on the mission,” said Joe Larson, vice president and head of government at OpenAI, in a statement to Fortune .

“ChatGPT Mil brings a familiar commercial experience into the Department’s secure environment, tailored to warfighter needs,” read a press release from the Pentagon.

The specialized version of ChatGPT, which kicked off the AI race when it launched in 2022, will keep data within its environment and not use it to train its models.

Service members can use both the specialized versions of ChatGPT and Grok for Controlled Unclassified Information (CUI) at Impact Level 5 (IL5), which refers to sensitive U.S. government information that is not classified, according to the Pentagon announcement.

The vast majority of military work is unclassified and deals with document heavy yet routine work in HR, logistics, and contracting, much of which could be aided by ChatGPT’s ability to process large amounts of information, said a person familiar with uses at OpenAI.

As for the military version of Grok, or Starshield AI’s Grok for Government, the Pentagon said in its announcement that it will give its personnel access to deep thinking-inference, as well as different levels of reasoning (auto, fast, and expert).

It will also enable “the Joint Force to execute missions faster and with greater precision across numerous operational contexts, ranging from market research analysis for acquisition professionals to supply chain management for logisticians,” the announcement read.
