A high-ranking executive at OpenAI who served a few days as its interim CEO during a period of turmoil last year said she’s leaving the artificial intelligence company. Mira Murati, OpenAI’s chief technology officer, said in a written statement Wednesday that, after much reflection, she has “made the difficult decision to leave OpenAI.” [time-brightcove not-tgx=”true”] “I’m stepping away because I want to create the time and space to do my own exploration,” she said. Two other top executives are also on their way out, CEO Sam Altman announced later Wednesday.
