It doesn’t “contain the original work” in the way it sounds. That sounds like there’s literally a stolen picture, sitting in the network, ready to be copy/pasted into the derivative work.

If you examined the network, you won’t see anything like the “stolen image”. It’s an entire latent space of many dimensions, where a point in the space is a concept.

A good metaphor might be a recipe for bread, or worded instructions on how to draw Mickey mouse.

It’s just that a computer is so good at following those instructions verbatim, it can draw Mickey mouse with uncanny ability.

Is “draw a circle at 100,200 of diameter ∅40 color hex 0xBEEFE5, draw a line from…” the same as Mickey Mouse? If I got the detail 100% and following those instructions gives Mickey mouse, am I distributing copyrighted work ?
