OpenAI’s chief research officer has left

OpenAI’s chief research officer, Bob McGrew, and a research VP, Barret Zoph, have left the company hours after OpenAI CTO Mira Murati announced she would be departing.

CEO Sam Altman revealed the two latest resignations in a post on X Wednesday evening, along with leadership transition plans.

“Mira, Bob, and Barret made these decisions independently of each other and amicably, but the timing of Mira’s decision was such that it made sense to now do this all at once, so that we can work together for a smooth handover to the next generation of leadership,” he said.

VP of research Mark Chen is being promoted to OpenAI’s new SVP of research, and will lead the company’s research org in partnership with Jakub Pachocki as chief scientist, Altman said.

Matt Knight, formerly head of security, will be OpenAI’s chief information security officer. And chief product officer Kevin Weil and VP of engineering Srinivas Narayanan will continue to lead OpenAI’s applied team, which is responsible for bringing the company’s tech to both consumer and enterprise customers.

Josh Achiam, a research scientist, will be taking on a new role as head of mission alignment. Altman says he’ll be “working across the company to ensure that we get all pieces (and culture) right to be in a place to succeed at the mission.”

“Mark, Jakub, Kevin, Srinivas, Matt, and Josh will report to me,” Altman added. “I have over the past year or so spent most of my time on the non-technical parts of our organization; I am now looking forward to spending most of my time on the technical and product parts of the company.”

In his post, Altman tried to assure staff — and those on the outside looking in — that the leadership changes were simply the normal course of business.

“Leadership changes are a natural part of companies, especially companies that grow so quickly and are so demanding,” he said. “I obviously won’t pretend it’s natural for this one to be so abrupt, but we are not a normal company, and I think the reasons Mira explained to me (there is never a good time, anything not abrupt would have leaked, and she wanted to do this while OpenAI was in an upswing) make sense.”

OpenAI is scheduled to have an all-hands meeting tomorrow.
