This repository contains software licenses that restrict software from being used in AI training datasets or AI technologies. - non-ai-licenses/non-ai-licenses

Even if these licenses cannot be considered as open source and libre (according to OSI and FSF definitions, the only ones which matter), several licenses prohibiting use of source code to train AI are listed in this repository. Nice initiative.
