Rohit Prasad, the executive who has led Amazon’s artificial intelligence initiatives and overseen the creation of its homegrown Nova AI models, is leaving the company at the end of the year.
In a memo Wednesday morning, Amazon CEO Andy Jassy named Peter DeSantis, a 27-year company veteran and top cloud infrastructure executive, to lead a new organization that combines the Nova and model research teams with its silicon and quantum computing groups.
AI researcher Pieter Abbeel, who joined the company last year when Amazon hired the founders of robotics startup Covariant, will lead the frontier model research team within Amazon’s AGI organization, while continuing his work with the company’s robotics team, according to Jassy’s memo.
Prasad’s departure comes two weeks after Amazon unveiled its Nova 2 models at its annual re:Invent conference, and as the company attempts to close the gap with AI rivals including OpenAI and Google in the race to develop increasingly capable AI systems.
He joined Amazon in 2013 during the early days of Alexa and was named senior vice president and head scientist for artificial general intelligence in mid-2023 as part of a broader effort to recharge the company’s AI initiatives in the face of stiff competition.
In his memo, Jassy framed the reorganization as an effort to unify Amazon’s most important AI bets at an “inflection point” for the technologies. The new organization will bring together Amazon’s most expansive AI models, including Nova and AGI, with its custom silicon development group, which builds chips including Graviton, Trainium, and Nitro, as well as its quantum computing efforts.
DeSantis, who is part of Amazon’s senior leadership team, will report directly to Jassy.
Prasad’s departure was mentioned toward the end of Jassy’s memo, with the Amazon CEO saying that he “has built a strong team, differentiated technology, growing customer momentum, and a culture of ambitious invention.”
The memo described the departure as Prasad’s decision, with Jassy calling him “missionary, passionate, and selfless” and thanking him for “everything he’s built here.”
It’s not yet clear what Prasad will do next.
Amazon has positioned itself as a major player in enterprise AI through its Bedrock platform. Its Nova models are competitive on industry benchmarks. The Nova Forge service, launched at re:Invent, lets businesses and developers customize models using their own data.
The company also unveiled a series of “frontier agents” at re:Invent, aiming to get ahead of the industry’s push toward autonomous AI systems for businesses.
But the company is still generally viewed as a fast follower in generative AI, trailing OpenAI, Google, and others in the perception of frontier model capabilities. Amazon has partnered closely with Claude maker Anthropic as a counterpunch to Microsoft’s partnership with ChatGPT maker OpenAI.
Developing story, more to come.
