AI Case Study

Obvious' artists create the first GAN-generated artwork to be auctioned and sold for $432,500

An AI artwork sold for $432,500, despite its estimated selling price of $7,000 to $10,000 at an auction at Christie's New York. The piece, titled Portrait of Edmond de Belamy, was created by Paris-based art collective Obvious with the use of Generative Adversarial Network algorithm (GAN). The system was fed information from 15,000 portraits painted between the 14th and 20th centuries.

Project Overview

"AI artwork sells for $432,500 — nearly 45 times its high estimate — as Christie’s becomes the first auction house to offer a work of art created by an algorithm

This portrait, however, is not the product of a human mind. It was created by an artificial intelligence, an algorithm defined by that algebraic formula with its many parentheses. And when it went under the hammer in the Prints & Multiples sale at Christie’s on 23-25 October, Portrait of Edmond Belamy sold for an incredible $432,500, signalling the arrival of AI art on the world auction stage.

The painting, if that is the right term, is one of a group of portraits of the fictional Belamy family created by Obvious, a Paris-based collective consisting of Hugo Caselles-Dupré, Pierre Fautrel and Gauthier Vernier. They are engaged in exploring the interface between art and artificial intelligence, and their method goes by the acronym GAN, which stands for ‘generative adversarial network’.


But one of the beguiling things about the depiction of Edmond Belamy is that it departs from a human idea of an 18th-century portrait. There is something weirdly contemporary about him: he looks unnervingly like one of Glenn Brown’s art-historical appropriations. Why might that be?

‘It is an attribute of the model that there is distortion,’ says Caselles-Dupré. ‘The Discriminator is looking for the features of the image — a face, shoulders — and for now it is more easily fooled than a human eye.’

It must also surely be the case that portraiture is an extremely tough genre for AI to take on, since humans are highly attuned to the curves and complexities of a face in a way that a machine cannot be. It turns out that the difficulty was part of the collective’s thinking. ‘We did some work with nudes and landscapes, and we also tried feeding the algorithm sets of works by famous painters. But we found that portraits provided the best way to illustrate our point, which is that algorithms are able to emulate creativity.’"

Reported Results

The Portrait of Edmond Belamy sold for $432,500.

Technology

"‘The algorithm is composed of two parts,’ says Caselles-Dupré. ‘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.’"
