Since ChatGPT took the world by storm in late 2022, OpenAI’s revenue and market value have skyrocketed. But internally, the company hasn’t necessarily had the smoothest ride. The A.I. giant, valued at $150 billion, lost a slew of top executives this year. On Wednesday (Sept. 25) alone, a trio of leaders, including chief technology officer Mira Murati, chief research officer Bob McGrew, and VP of research Barret Zoph, all announced their departures. They join a larger group of former OpenAI employees who have left for rival A.I. developers and startups. As of now, CEO Sam Altman is one of only two active remaining members of the company’s original 11-person founding team.
OpenAI hasn’t just lost employees—it has also rehired some familiar faces. In May, OpenAI welcomed back Kyle Kosic, who worked at the company between 2021 and 2023 on its technical staff. Kosic left last year to join Elon Musk’s xAI. Several other outgoing OpenAI employees have taken similar routes and gone on to work for competing A.I. companies, showing just how competitive the industry is at the moment.
Here’s a look at some of the top leaders OpenAI has lost in 2024 thus far:
Andrej Karpathy, research scientist
Andrej Karpathy has left OpenAI not once but twice. One of OpenAI’s 11 founders, Karpathy helped build the company’s team on computer vision, generative modeling and reinforcement learning. He first departed in 2017 to lead Tesla’s Autopilot effort. Returning to OpenAI in 2023, Karpathy left once again in February this year to focus on “personal projects.” He subsequently established Eureka Labs, an A.I. education startup.
Ilya Sutskever, chief scientist and co-head of the super alignment team
A renowned machine learning researcher, Ilya Sutskever helped co-found OpenAI nearly a decade ago and served as the company’s chief scientist. He was also notably a member of the four-person board that temporarily ousted Altman last year before reinstating him. Sutskever, who was subsequently removed from the board, later said he regretted his involvement in the brief ouster. In May, he announced his departure from OpenAI and said he was leaving for a venture that is “very personally meaningful.”
This project was revealed to be Safe Superintelligence, a startup focused on developing a safe form of artificial general intelligence (AGI), a type of A.I. that can think and learn on par with humans. Earlier this month, the company was valued at $5 billion after raising $1 billion from investors, including Andreessen Horowitz and Sequoia Capital.
Jan Leike, co-head of the super alignment team
Just days after Sutskever left, OpenAI executive Jan Leike announced his resignation as well. Sutskever and Leike co-ran the company’s safety team, which has since been disbanded. Leike said he decided to leave in part due to disagreements with OpenAI leadership “about the company’s core priorities,” citing a lack of focus on safety processes around developing AGI. Leike has since taken up a new role as head of alignment science at Anthropic, an OpenAI rival founded by former OpenAI employees Dario Amodei and Daniela Amodei.
John Schulman, head of alignment science
John Schulman, another OpenAI co-founder, made significant contributions to the creation of ChatGPT. After Leike’s departure, Schulman became head of OpenAI’s alignment science efforts and was appointed to its new safety committee in May. That’s why Schulman’s decision in August to step away from the company came as a surprise—especially when he revealed that he would be joining Anthropic. “This choice stems from my desire to deepen my focus on A.I. alignment and to start a new chapter of my career where I can return to hands-on technical work,” said Schulman on X, where he also clarified that his decision to step away from OpenAI wasn’t connected to a lack of support for alignment research.
Peter Deng, vice president of consumer product
Peter Deng, a top OpenAI product executive, also decided to step away from the company earlier this year. Having first joined OpenAI last year, he ended his tenure as vice president of product in July, according to his LinkedIn. Deng, who also previously held product leader positions at companies like Uber (UBER) and Meta (META), has not publicly revealed his next steps.
Greg Brockman, president
Greg Brockman, often seen as Altman’s right-hand man, hasn’t technically left the company but is instead taking a sabbatical through the end of 2024. In August, he announced his time off and described it as the “first time to relax since co-founding OpenAI nine years ago.” Brockman started off as OpenAI’s chief technology officer before becoming the company’s president in 2022. He indicated that he plans to return to OpenAI, noting that “the mission is far from complete; we still have a safe AGI to build.”
Mira Murati, chief technology officer
Mira Murati, one of OpenAI’s most public-facing figures, resigned earlier this week after more than six years with the company. “I’m stepping away because I want to create the time and space to do my own exploration,” said Murati, who notably served as interim CEO during Altman’s brief ousting last year, on X. Adding that she will “still be rooting” for OpenAI, Murati said her primary focus currently is “doing everything in my power to ensure a smooth transition, maintaining the momentum we’ve built.” Altman praised her leadership in a statement on X, describing Murati as instrumental to OpenAI’s “development from an unknown research lab to an important company.”
Bob McGrew, chief research officer
Shortly after Murati’s resignation, Bob McGrew, OpenAI’s chief research officer, also announced plans to leave the company. He simply said on X, “It is time for me to take a break.” Having previously worked at PayPal (PYPL) and Palantir, McGrew started off as a member of OpenAI’s technical staff and has been serving as OpenAI’s chief research officer since August.
Barret Zoph, vice president of research
Barret Zoph is the third executive who announced his resignation this week. Like his two colleagues, Zoph said it’s a “personal decision based on how I want to evolve the next phase of my career.” Zoph, a former research scientist at Google (GOOGL), joined OpenAI in 2022 and played a large role in overseeing OpenAI’s post-training team.
Murati, McGrew and Zoph made their decisions independently of each other, according to Altman, but decided to depart simultaneously “so that we can work together for a smooth handover to the next generation of leadership.” The CEO conceded that, while the abruptness of the leadership changes isn’t the most natural, “we are not a normal company.”
