A.I. companies like xAI can and should do more not just to respond quickly and decisively when their models behave badly, but also to prevent them from generating such material in the first place. This means rigorously testing the models to learn how and why they can be manipulated into generating illegal sexual content — then closing those loopholes. But current laws don’t adequately protect good-intentioned testers from prosecution or correctly distinguish them from malicious users, which frightens companies from taking this kind of action.
