The open-weights letter says defenders need models as capable as attackers

The letter acknowledges open-weight risks but rejects blanket bans

The authors do not ignore the risks: once weights are released, they are outside the original developer’s control, and modified versions are hard to trace or reverse. Still, they argue that banning open weights is the wrong answer.

Their reasoning is that attackers already have access to advanced AI, so defenders need models with comparable capability to detect and respond to emerging threats. Open models, in this view, broaden defensive capacity rather than simply increasing exposure.
