A Hacker Stole OpenAI Secrets, Raising Fears That China Could, Too

Early last year, a hacker gained access to the internal messaging systems of OpenAI, the maker of ChatGPT, and stole details about the design of the company's A.I. technologies.

The hacker lifted details from discussions in an online forum where employees talked about OpenAI's latest technologies, according to two people familiar with the incident, but did not get into the systems where the company houses and builds its artificial intelligence.
