At OpenAI, Madry will work alongside chief scientist Jakub Pachocki on safety and security challenges as AI systems become more powerful. Pachocki said Madry’s judgment is increasingly valuable for shaping the company’s strategy and for the broader industry. Madry’s expertise is in robust machine learning, which aims to make models behave reliably even under messy, unexpected, or adversarial inputs. The move signals that OpenAI is placing safety work close to the core of its research organization, especially regarding cybersecurity threats that could be exploited by both defenders and attackers.
