Former Google Engineer Sentenced for Stealing China AI Secrets
Linwei Ding worked for Google and could access secret information about its AI computers.
Prosecutors said he copied many files and moved them to personal accounts and a computer.
The files explained how Google connects thousands of computer chips to train AI models.
They included information about Google’s special Tensor Processing Units and other hardware.
Prosecutors said Ding was also working with technology companies in China.
A jury found him guilty of stealing trade secrets and espionage-related counts.
The judge later removed the economic-espionage charges after finding the evidence insufficient to prove he intended to help the Chinese government during part of the alleged conduct.
Ding was sentenced to almost one year in prison and received additional financial penalties.
The case comes during a major competition between the United States and China over AI technology.
Linwei Ding was sentenced to 12 months minus one day in prison for stealing Google AI infrastructure information.
Prosecutors said Ding transferred more than 500 files, while later court filings involved over 1,000 files and more than 2,000 pages.
The stolen material described Google’s Tensor Processing Units, GPUs, networking tools, and systems for coordinating thousands of chips.
Ding developed ties to Chinese technology ventures, including Rongshu and his own company, Zhisuan, while working at Google.
He must serve two years of supervised release, pay more than $189,000 in restitution, and pay a $25,000 fine.

Prosecution and Court
Prosecutors described Ding’s actions as a brazen effort to steal Google property and said the files could help others avoid years of planning and millions of dollars in development costs.
