John Schulman, one of the co-founders of OpenAI, has left the company for rival AI startup Anthropic.
In addition, OpenAI president Greg Brockman is taking an extended leave — through the end of the year — after nine years at the company to “relax and recharge,” the company confirmed.
Peter Deng, a product manager who joined OpenAI last year after leading products at Meta, Uber, and Airtable, also exited some time ago, the company confirmed. The news of Brockman’s and Deng’s departures was earlier reported by The Information.
A spokesperson shared this statement about Schulman: “We’re grateful for John’s contributions as a founding team member at OpenAI and his dedicated efforts in advancing alignment research. His passion and hard work have established a strong foundation that will inspire and support future innovations at OpenAI and the broader field.”
Schulman posted about the decision on X today, saying that it stemmed from a desire to deepen his focus on AI alignment — the science of ensuring AI behaves as intended — and engage in more hands-on technical work.
“I’ve decided to pursue this goal at Anthropic, where I believe I can gain new perspectives and do research alongside people deeply engaged with the topics I’m most interested in,” Schulman said. “I am confident that OpenAI and the teams I was part of will continue to thrive without me.”
Schulman’s involvement with OpenAI began shortly after he completed a Ph.D. in electrical engineering and computer sciences at UC Berkeley. He played a pivotal role in creating the AI-powered chatbot platform ChatGPT by leading OpenAI’s reinforcement training org, which fine-tunes generative AI models to follow human instructions.
Following the departure of AI safety researcher Jan Leike (who also now works at Anthropic), Schulman became the head of OpenAI’s alignment science efforts, also known as the “post-training” team. He was also a member of OpenAI’s recently formed safety committee; it’s unclear who might replace Schulman in that role.
Despite the controversies swirling around OpenAI, particularly with regard to the company’s approach to and treatment of AI safety research, Schulman said that he wasn’t leaving OpenAI due to a lack of support.
“Company leaders have been very committed to investment in [alignment research],” Schulman said. “My decision is a personal one, based on how I want to focus my efforts in the next phase of my career.”
With Schulman’s departure, only three of OpenAI’s 11 original founders remain: OpenAI CEO Sam Altman, Brockman and Wojciech Zaremba, lead of language and code generation.
“Thank you for everything you’ve done for OpenAI!” wrote Altman on a post on X.” You are a brilliant researcher, a deep thinker about product and society, and mostly, you are a great friend to all of us. We will miss you tremendously and make you proud of this place.”
