Details

Gemini 3.1 Pro, Google Cloud's latest commercial model, has been added to GenAI.mil, the Pentagon's enterprise generative AI platform. After running in preview for a few weeks, it was officially rolled out, reaching federal users about 8 weeks after commercial customers.

  • Currently, up to 3 million people have access, of whom more than 1.3 million are actively using it.
  • Since its December 9 launch, GenAI.mil reached 500,000 users in 1 week and 1 million users in 1 month.
  • The Department of Defense uses it for document summarization, task automation, and data-intensive document processing, and it also operates in IL5 environments.

The use cases are concrete. Navy Recruiting Command used Gemini to cut the time to build an automated database for personnel and account management from years to 3 months, and Defense Logistics Agency shortened the drafting time for statements of work from weeks to hours, which helped secure $1 million in last-minute budget funding.

Additionally, Agent Designer now allows agents to be configured using natural language alone, and the Department of Defense stated that more than 100,000 AI agents have already been created on GenAI.mil.
