These models do not duplicate except in corner cases where the training set has massive persistent patterns (like a watermark) or if there's massive duplication in the data set (especially happens with famous artwork already in the public domain). This is not an intentional thing, and in every case is actually counter-productive to the functioning of the model. If you used a really cleverly and exhaustively and iteratively prompted midjourney image to recreate a copyrighted painting, that WOULD be duplication, just like a physical artist can paint a copy of a copyrighted painting by hand. Duplication is the end result, not the intermediary. That's why transformative collage is fine.
