OpenAI research chief Mark Chen calls for cultural reset after recent controversies

OpenAI chief research officer Mark Chen told Nature the company needs a cultural reset after weeks of scrutiny, including July claims its models hacked Hugging Face, Australia's report that OpenAI agents breached a national health-care website, and dispute over whether a touted math breakthrough drew on prior human work. Chen, who leads model development, discussed OpenAI's safety pivot and AI in science, rejecting math-only models and citing shorter drug-discovery pipelines as a goal.
