From a brilliant longtime AI insider with intimate access to the world of Sam Altman's OpenAI from the beginning, an eye-opening account of the tech arms race in history that is reshaping the planet in real time

When AI expert and investigative journalist Karen Hao first began covering OpenAI, she thought they were the good guys. Founded as a nonprofit with safety enshrined, the organization was meant to act as a check against more purely mercantile forces. What could go wrong?

Over time, Hao wrestled with that question. Increasingly, she realized that this disruptive sector’s vision of success requires an unprecedented amount of resources: the “compute” power of high-end chips and the processing capacity to create massive large language models, the sheer volume of data that needs to be amassed at scale, the humans “cleaning up” that data for sweatshop wages throughout the Global South, and a truly alarming spike in the usage of energy and water underlying it all. We have entered a new age of empire where only a handful of globally scaled companies can enter the field of play.

Armed with billions, pushing on trillions, OpenAI is setting a breakneck pace—toward what end, not even they can define. All this time, Hao has maintained deep sourcing within the company and the industry, keeping in intimate contact with the story that shocked the entire tech industry—Altman’s sudden firing and triumphant return. The behind-the-scenes of what happened is revelatory of who the people controlling this technology really are. But this isn’t just the story of a single company. As Hao shows through intrepid global reporting, the enormous wheels of extraction grind on. An astonishing eyewitness view from both the command capsule of the new economy and where the real suffering happens, Empire of AI pierces the veil of the industry defining our era.
