Training data sources of models

[The-Nickname]

Hi, great project I like it quite a lot.
But I have a question where I couldnt find an answer in the FAQ etc:
What training data do the default models use under which license is the training data and is it linked somewhere?
I mainly want to know if every author of each part from the training data gave their consent for using it like this(or made it CC0 or similar).

Best Regards
