All the top OpenAI figures who have left since the 2023 attempt to oust CEO Sam Altman

Karpathy announced his departure from OpenAI on X in February.

“First of all nothing ‘happened’ and it’s not a result of any particular event, issue or drama,” he wrote at the time.

“Actually, being at OpenAI over the last ~year has been really great,” he added. Karpathy has since founded Eureka Labs, an AI company focused on education.

Karpathy started at OpenAI in 2015 as a founding research scientist, making him a co-founder of the company. He left in 2017 for a job at Tesla, according to his website. He came back to OpenAI in 2023.

Leike announced his departure from OpenAI in a series of posts on X, formerly known as Twitter, in May. That month, he took a job as a co-lead of Anthropic’s alignment science team.

At OpenAI, Leike was co-head of the company’s Superalignment team. Leike and co-founder Ilya Sutskever had been charged by OpenAI with leading a team to figure out how to keep AI safe for humans to use. The goal of the Superalignment team is to “ensure AI systems much smarter than humans follow human intent,” according to a post on OpenAI’s website from last year.

While he praised his team in the posts, he also said: “I have been disagreeing with OpenAI leadership about the company’s core priorities for quite some time, until we finally reached a breaking point.”

He added in a subsequent post that “over the past years, safety culture and processes have taken a backseat to shiny products.”

Chief Technology Officer Murati said that she would leave OpenAI in a memo to the company’s employees on Wednesday.

“I’m stepping away because I want to create the time and space to do my own exploration,” Murati wrote in the memo.

Murati also briefly served as CEO in November as OpenAI’s board tried to oust Altman. The effort was unsuccessful, and Altman returned to his role days after being fired.

In March, the New York Times reported that Murati had expressed concerns with Altman’s leadership to the board before the attempted shakeup. Murati’s lawyer told BI at the time: “The claims that she approached the board in an effort to get Mr. Altman fired last year or supported the board’s actions are flat wrong.”

McGrew has been OpenAI’s chief research officer since August and has worked at the company since 2017, according to his LinkedIn page.

“It is time for me to take a break,” McGrew wrote in a Wednesday post on X. “There is no better capstone to my work here than shipping o1 to the world,” he added, referring to OpenAI’s latest model.

McGrew said he would stay at OpenAI for two more months as Mark Chen assumes leadership of the company’s research team.

Zoph has been vice president of research, post-training since September 2022, according to his LinkedIn page.

“I got to join right before ChatGPT and helped build the post-training team from scratch with John Schulman and others,” Zoph wrote in a post on X on Wednesday, adding that he decided to leave “based on how I want to evolve the next phase of my career.”

While OpenAI announced the departures of McGrew, Murati, and Zoph on Wednesday, Altman wrote in a memo to employees that all three “made these decisions independently of each other and amicably.”
