Amazon shakes up AI team as veteran Prasad leaves, DeSantis promoted

We are at this inflection point with several of our new technologies that will power a significant amount of our future customer experiences,” said Amazon CEO Andy Jassy in the post on Wednesday.
Cloud executive Peter DeSantis, a 27-year Amazon veteran, will lead the new unit overseeing its most advanced technologies, according to a company post. Rohit Prasad, who helped build the Alexa voice assistant and led its AI efforts recently, will step down at year’s end.
Pieter Abbeel, who joined Amazon last year, is set to head up frontier model research with the AGI organization and continue to work on robotics. He came to Amazon when the company hired the founders of Covariant, a robotics startup.
