Tech Moves: OpenAI nabs top Microsoft AI researcher; Lime taps Amazon VP as CTO
Sebastien Bubeck, a top researcher from Microsoft who was most recently vice president of AI and a distinguished scientist, is joining OpenAI.
The Information first reported on Bubeck’s departure, describing him as one of Microsoft’s “most prominent artificial intelligence researchers.”
Bubeck joined Microsoft a decade ago and previously was vice president of generative AI research.
“Sebastien has decided to leave Microsoft to further his work toward developing AGI (artificial general intelligence),” a Microsoft spokesperson said in a statement. “We appreciate the contributions Sebastien has made to Microsoft and look forward to continuing our relationship through his work with OpenAI.”
Microsoft has invested more than $13 billion into OpenAI, which just raised a massive $6.5 billion funding round.
The partnership gives OpenAI substantial computing resources and funding, while Microsoft gets access to cutting-edge AI technology.
More recently Microsoft has reportedly been developing its own large language model separate from OpenAI’s GPT-4. OpenAI execs, meanwhile, say Microsoft isn’t moving fast enough to provide computing power.
OpenAI just opened an office in Bellevue, Wash., near Microsoft’s headquarters in Redmond.

“I’m excited to be a member of the team bringing sustainable, convenient, affordable transportation to people around the globe,” Jenkins wrote on LinkedIn. “We’ve got a lot of fun technical challenges to solve as we innovate toward the future of shared transportation.”
Jenkins was previously director of engineering at Hestan Smart Cooking, head of engineering at Pinterest, and co-founded Seattle-based cooking startup Meld.
