In a cavernous warehouse north of New York City, a 16-foot robot outfitted with a cutting tool etched intricate grooves into a faceless marble head atop an alien-like torso.

Water sprayed into the air as an image created with artificial intelligence entered the physical world.

In February, during a three-month stint as OpenAI’s first artist in residence, Alexander Reben gained early access to the start-up’s Sora text-to-video tool, which instantly generates videos up to a minute in length from written or spoken prompts.

Mr. Reben, an M.I.T.-trained technologist, used Nvidia’s neural radiance field technology to turn Sora’s A.I.-generated imagery into 3-D models. The cutting tool, run by a small company called Monumental Labs, turned one of those into a four-foot-tall sculpture carved from white Italian marble veined with black and gray.

While many artists view A.I. as a threat to their livelihoods, Mr. Reben, whose residency ended in April, embraces it as a collaborator.

“I got a closer view of how innovation happens within an A.I. company, and got a better idea of why it’s important to push the edges and try new things,” Mr. Reben, 39, said.
