I wonder how effectively they can enforce a ban… there are ways of buying OAI completions where you never even reveal your identity.
They don't want that the bad publicity when that goes wrong of course, but the prevailing concerns are (1) giving allied politicians room to say "they care! see how they try!" as they try to shape regulation into a moat, and (2) preventing competition against their own projects and products for large "defense" institutions
They're just making sure that this kind of use isn't normalized or presumed -- a much lower standard than eradicating it completely.
Large defense contractors build their own systems: Some of the best tools for CAD, SCADA, CAM and project-management come from companies like Thales and Dassault. I also have it on good authotity that major US defense contractors' people are very explicitly banned from interacting with any non-local-hosted LLM.
Whereas, uncensored LLMs (and the like) with knowledge of firearms and explosives manufacturing are a public-health risk for sure, but not a national-security risk.
Analogously, with a lot of grey area stuff, a person can almost surely get away with it ... but not if they post it online and it gets attention.
yes they can flag certain prompts, true
