AI-created painting to be auctioned in New York

The portrait was created by artificial intelligence, which studied thousands of portraits to create its own artwork.

A painting created by artificial intelligence is to be sold at auction in New York on Thursday and is expected to go for more than 7,000 dollars (£5,400).

The portrait was created by software from French art collective Obvious, with the AI system comparing its own work with those of human artists before updating its own work until it wasn’t possible to tell the difference between them.

The artwork will go on sale at Christie’s in New York, and is estimated to sell for between 7,000 and 10,000 dollars.

Hugo Caselles-Dupre, from Obvious, told Christie’s that the algorithm used thousands of portraits as part of its comparisons.

“The algorithm is composed of two parts,” he said.

“On one side is the Generator, on the other the Discriminator. We fed the system with a data set of 15,000 portraits painted between the 14th century to the 20th. The Generator makes a new image based on the set, then the Discriminator tries to spot the difference between a human-made image and one created by the Generator.

“The aim is to fool the Discriminator into thinking that the new images are real-life portraits. Then we have a result.”
