Are these just tweaked copies of images that already exist?

No!

Accomplice’s image generation AI works by using a deep learning model trained on a large dataset of images.

The model is able to generate new images by learning to predict the pixels in an image based on the surrounding pixels.

The model is able to generate images that are similar to the ones it was trained on, but can also create new and original images.

But generative AI like Accomplice is not just combining existing images together, it is using its knowledge of the world to create all new images never created before.
