Rohit Prasad, SVP and head scientist of artificial general intelligence at Amazon, speaking at Fortune Brainstorm AI 2024 in San Francisco. Stuart Isett/FortuneAmazon CEO Andy Jassy
dropped an AI bombshell on employees yesterday,
announcing that Rohit Prasad—who has led Amazon’s AGI team since 2023, overseeing the development of the company’s Nova models—will depart at the end of the year.
Prasad previously served as the head scientist behind Amazon’s Alexa voice assistant, a role he held from the product’s earliest days.
Replacing him is longtime Amazon Web Services (AWS) executive Peter DeSantis, who will lead a new organization that drives the development of its AI models, custom computer chips (which include its Graviton, Trainium, and Nitro chips), and quantum computing efforts.
DeSantis will report directly to Jassy.
As part of the changes, Pieter Abbeel, an Amazon Distinguished Scientist in robotics who is also an AI and robotics professor at UC Berkeley, will lead the company’s frontier model research team. Abbeel came to Amazon in 2024 along with other cofounders of his robotics startup Covariant.
The news of Prasad’s departure comes as somewhat of a surprise, given that he was recently at Amazon’s re:Invent conference discussing the latest Nova models. (He also
spoke at Fortune Brainstorm AI 2024.)
However, over the past two years, there has been significant media coverage suggesting that Amazon’s Alexa AI and AGI-related efforts have struggled and fallen behind competitors.
