> Do we know what data was used? And what the constraints were around it? The fact that the question/accusation has been raised a great many times and they have not stated "we know we haven't used information without licence because we had procedures to check licensing for all the data used to train our models", would certainly imply that they scraped data for training without reference to licensing, which makes it very likely that the models are based significantly on copyrighted and copyleft covered information. > Do we know it was used without permission No, we don't know for sure. But the balance of probabilities is massively skewed in that direction. There are enough examples of image producing AIs regurgitating obvious parts of unlicensed inputs, as an indication of the common practise of just scraping everything without a care for permission. So asking for those with other models to state how they checked for permission for the input data is reasonable.
