I just realized something, the stable AI initially used the work of Yoneyamai (米山舞) that although its name ends in"AI" it is its name, it is not that it contains AI; but there are also more artists of her style and they are the ones who are in the majority of "legal" AIs that are not supposed to use images without copyright, such as, for example, Mika Pikazo, in fact the particular style of the AIs belongs to this artist " Mika Pikazo", remember that AIs are in short "mathematically related data", so there is no other option than to use the images directly, the AI does not have eyes nor does it process images like the human being, in fact they all use the same system, convolutional neural, which in itself directly takes the image data and breaks it into pieces that it calls parameters, for example the eyes, the silhouette, etc. but this use is the most illegal of all since it necessarily requires the image data to work with it.
