As prominent AI researchers continue to leave Google DeepMind, details about the reasons behind the departures are starting to emerge. Semafor reports that CEO Demis Hassabis stepped back from daily operations about a year ago and turned those duties over to new DeepMind chief Koray Kavukcuoglu. Hassabis wasn't forced out but reportedly found management unfulfilling and sees himself more as a visionary scientist than an executive.

CNBC reports that many researchers are frustrated by limited access to Google's TPU chips. At the same time, Google Cloud sells those chips to rivals like Anthropic, the very competitors Google's own researchers are expected to beat. Google allocates computing capacity years in advance among research teams, product operations, and cloud customers, but priorities can shift with little notice, a source told CNBC. Google's bureaucracy also reportedly makes younger companies more appealing.

As if to prove the point, Google announced today that "exciting frontier AI lab" Mirendil will use more than $100 million worth of TPUs and Nvidia GPUs through a Google Cloud partnership.
