It is my understanding that you can compare weights and with a high degree of confidence determine what the parent of a model is unless the fine tuning destroyed all the original information in which case there isn’t a huge reason to have fine tuned to begin with. There are other ways to scramble weights which make the comparisons a lot harder to do though which will matter if weights ever are considered copyrightable
