Please enlighten me how that would work? Because even if you only use open source, that would still mean, if it's a permissive licence, you would have to give proper attribution (which AI can't do) and if it's copyleft, all your code would have to be under the same licence as the code and also give proper attribution.

Edit: I just looked your model up, apparently they ensure "ethically sourced training data" by only using pupicly available data and "respecting machine readable opt outs", which is not how copyright works.
