How Baidu Almost Snagged Hinton: The Secret AI Auction That Shaped Deep Learning

On October 8, 2024 the Royal Swedish Academy announced the Nobel Prize in Physics for John J. Hopfield and Geoffrey E. Hinton, recognizing their foundational work on artificial neural networks and machine learning.

Geoffrey Hinton, often called the "AI godfather," had long been a pivotal figure in deep learning, and less widely known is that about eleven years before his fame, the Chinese tech giant Baidu was the first company to try recruiting him.

In March 2013 Google spent $44 million to acquire DNNResearch, a Toronto‑based startup founded by Hinton and his two students, Alex Krizhevsky and Ilya Sutskever, which at the time had no product and only three employees.

The acquisition proved prescient: Hinton’s breakthroughs, especially the 2012 AlexNet paper that slashed ImageNet error rates, sparked a rapid rise of deep learning, and Google soon became a leader in AI technology.

Ba​idu and Hinton Neared an Agreement

According to Cade Metz’s book Genius Makers , a 2012 NIPS auction saw Google, Microsoft, DeepMind and Baidu competing for Hinton’s nascent company. Baidu, having built the world’s first GPU‑CPU parallel deep‑learning platform, approached Hinton through its vice‑president of strategic investment, offering $12 million for a three‑year contract.

Hinton’s students advised him to seek a higher‑valued acquisition rather than a simple employment contract. After consulting a Toronto lawyer, Hinton chose an auction format, inviting the four companies to submit sealed bids via Gmail.

Highest Bidder Baidu Didn’t Win

The auction proceeded with escalating bids: Baidu’s initial $12 million offer rose to $2.5 million, $3 million, $3.5 million, and eventually $4 million‑plus, while Google and Microsoft also increased their offers. DeepMind bid with stock instead of cash and later withdrew, and Microsoft exited after a $20 million bid.

When the price reached about $24 million, Baidu’s Beijing executive raised the bid to $25 million, $30 million, $35 million, and finally $44 million. Hinton shortened the bidding window to 30 minutes, pushing the total to $43 million, but at that point he had already decided to sell to Google.

Hinton informed Baidu that any further communication would be forwarded to his new employer, effectively ending the competition. He later reflected that finding a suitable home for his research mattered more than the highest price.

The episode, documented in Genius Makers , is portrayed as the opening act of a new AI arms race between the United States and China, highlighting the strategic importance of deep learning and the pivotal role of Chinese engineers like Yu Kai and Deng Li in the bidding drama.
