As senior AI researchers continue to leave Google DeepMind, reporting is surfacing reasons behind the departures. Two recurring themes: limited access to Google's TPU chips, and a conflict of interest where Google Cloud sells those same chips to rivals the researchers are expected to beat.
Semafor reported that CEO Demis Hassabis stepped back from daily operations about a year ago, turning those duties over to DeepMind chief Koray Kavukcuoglu. Hassabis was not forced out, but reportedly found management unfulfilling and sees himself more as a visionary scientist than an executive.
CNBC reported that many researchers are frustrated by limited access to Google's TPU infrastructure. Google allocates computing capacity years in advance across research teams, product operations, and cloud customers, but priorities can shift with little notice, a source told CNBC. The reporting also points to Google's internal bureaucracy as a reason younger companies look more appealing, alongside the fact that Google Cloud sells TPUs to competitors such as Anthropic.
External customers ahead of internal teams
The timing is awkward for Google. The same week it announced the departure of Jeff Dean after 27 years and Hassabis stepping back, it said frontier AI lab Mirendil will use over $100 million worth of TPUs and Nvidia GPUs through a Google Cloud partnership. The arrangement puts external customers ahead of some internal researchers in line for the chips those researchers helped build the demand for.
Google has not publicly disputed the reporting. The departures add to a stretch where DeepMind has lost both a CEO and a chief scientist, leaving its talent pipeline and chip allocation under scrutiny as demand for compute outpaces supply.
