OpenAI this week quietly deleted language expressly prohibiting the use of its technology for military purposes. Up until January 10, OpenAI's "usage policies" page included a ban on "activity that has high risk of physical harm, including," specifically, "weapons development" and "military and warfare." That plainly worded prohibition against military applications would seemingly rule out any official, and extremely lucrative, use by the Department of Defense or any other state military. The new policy retains an injunction not to "use our service to harm yourself or others" and gives "develop or use weapons" as an example, but the blanket ban on "military and warfare" use has vanished. OpenAI spokesperson Niko ... Felix [said] that OpenAI wanted to pursue certain "national security use cases that align with our mission," citing a plan to create "cybersecurity tools" with DARPA, and that "the goal with our policy update is to provide clarity and the ability to have these discussions." The real-world consequences of the policy are unclear. Last year, The Intercept reported that OpenAI was unwilling to say whether it would enforce its own clear "military and warfare" ban in the face of increasing interest from the Pentagon and U.S. intelligence community. "Given the use of AI systems in the targeting of civilians in Gaza, it's a notable moment to make the decision to remove the words 'military and warfare' from OpenAI's permissible use policy," said [former AI policy analyst] Sarah Myers West.
