Microsoft last year proposed using OpenAI’s mega-popular image generation tool, DALL-E, to help the Department of Defense build software to execute military operations, according to internal presentation materials reviewed by The Intercept. The revelation comes just months after OpenAI silently ended its prohibition against military work.

The Microsoft presentation deck, titled “Generative AI with DoD Data,” provides a general breakdown of how the Pentagon can make use of OpenAI’s machine learning tools, including the immensely popular ChatGPT text generator and DALL-E image creator, for tasks ranging from document analysis to machine maintenance. (Microsoft invested $10 billion in the ascendant machine learning startup last year, and the two businesses have become tightly intertwined. In February, The Intercept and other digital news outlets sued Microsoft and OpenAI for using their journalism without permission or credit.)

The publicly accessible files were found on the website of Alethia Labs, a nonprofit consultancy that helps the federal government with technology acquisition, and discovered by journalist Jack Poulson. On Wednesday, Poulson published a broader investigation into the presentation materials. Alethia Labs has worked closely with the Pentagon to help it quickly integrate artificial intelligence tools into its arsenal, and since last year has contracted with the Pentagon’s main AI office. The firm did not respond to a request for comment.

One page of the Microsoft presentation highlights a variety of “common” federal uses for OpenAI, including for defense. One bullet point under “Advanced Computer Vision Training” reads: “Battle Management Systems: Using the DALL-E models to create images to train battle management systems.” Just as it sounds, a battle management system is a command-and-control software suite that provides military leaders with a situational overview of a combat scenario, allowing them to coordinate things like artillery fire, airstrike target identification, and troop movements. The reference to computer vision training suggests artificial images conjured by DALL-E could help Pentagon computers better “see” conditions on the battlefield, a particular boon for finding — and annihilating — targets.
