OpenAI’s head ethicist, Chloé Bakalar, quietly left the company at some point in July after having been hired the previous August. Whoever that source is, they apparently also said Bakalar hadn’t been replaced, and that she had been the sole dedicated ethicist at OpenAI. Chloé Bakalar, Ph.D., Chief Ethicist, Responsible AI (RAI) at @Meta, discussed generative AI and healthcare. In recent weeks, OpenAI has been front-and-center in a cascade of overlapping and bewildering news stories about AI safety and the government’s role in regulating it. Head of Safety Systems Johannes Heidecke and Joshua Achiam, who has worn many hats as an OpenAI safety specialist, also left this summer.
