OpenAI is bringing back Aleksander Madry, its former head of preparedness, months after he left the ChatGPT maker to pursue new opportunities, as he says the rapid advancement of artificial intelligence has made safety and security a more urgent priority.
Madry announced his return in a post on X, saying what he initially viewed as a departure had turned into more of a sabbatical.
"When I left a few months ago, I felt that the most important thing to focus on was making AI more useful to people," Madry wrote. "But we've since entered a different regime of AI progress. One in which getting the safety and security challenges of increasingly capable AI right has to become a central priority."
Madry will return to OpenAI and work alongside Jakub Pachocki, OpenAI's chief scientist, to help chart a path through those challenges.
"As AI becomes more capable, I'm focused on questions around the pace and implications of progress, and how they should inform the strategy of OpenAI and across the field. I asked Aleksander to come back to OpenAI to work with me on these topics. I value his judgment and am glad to have him on the team again," Pachocki replied to Madry's post on X.From AI Safety To Economic Impact
Madry announced his departure from OpenAI in May, describing his nearly three years at the company as an "experience of a lifetime."
At the time, he said he wanted to focus on how AI could transform the economy, including how businesses understand information, make decisions and operate.
Madry joined OpenAI in 2024 and served as head of preparedness, a role focused on identifying and addressing potentially catastrophic risks from advanced AI models. He was later reassigned to work on AI reasoning, CNBC reported at the time.
Before joining OpenAI, Madry directed MIT's Center for Deployable Machine Learning and served as a faculty co-lead of the MIT AI Policy Forum.
OpenAI Faces Expanding AI And Infrastructure Challenges
Madry's return comes as OpenAI expands its computing infrastructure to support increasingly advanced AI systems, with major investments and executive changes reshaping its operations.
Last week, OpenAI appointed former xAI infrastructure executive Uday Ruddarraju as chief technology officer for compute, following his promotion in July.
Sachin Katti, who previously led the infrastructure unit, is preparing to step down from the role and remain with the company as an adviser.
In July, Katti took charge of GPT-Infra, leading efforts to apply OpenAI's models to semiconductor design and develop infrastructure. He recently noted that customers were already testing the models to develop central processing units (CPUs) and edge chips.
The initiative will now be overseen by Richard Ho, who leads OpenAI's chip efforts.
OpenAI CEO Sam Altman has projected that the company will spend trillions of dollars on infrastructure to develop more advanced AI models and broaden their use.
In recent months, several executives involved in securing, financing, and developing data center capacity have left the company.
Chris Malone, who was involved in managing OpenAI's data center expansion, departed the company in August. Earlier this year, Peter Hoeschele, a key figure in the company's Stargate infrastructure project, joined Meta Platforms alongside two other colleagues.
