Charles Yang, who previously served as an AI for Science Fellow at Renaissance Philanthropy and an AI policy Advisor at the U.S. Department of Energy, began his role last month. He will work with the institute's research teams to surface data on frontier AI. This appointment comes as Anthropic continues its rapid hiring pace, including the recent addition of OpenAI co-founder Andrej Karpathy, ahead of a reported October IPO with a potential $2 trillion valuation.
