An internal memo sent to OpenAI staff on Saturday after former CEO Sam Altman's abrupt firing reiterates that "a breakdown in communication" led to the decision, not "malfeasance or anything related to our financial, business, safety, or security/privacy practices," according to Axios and The New York Times. The memo obtained by both publications was sent to employees by OpenAI's Chief Operating Officer Brad Lightcap. Speculation has been nonstop since Altman was ousted unexpectedly as CEO on Friday and dropped from the company's board of directors, with little concrete information from OpenAI itself to go on. In its announcement of the decision, the board said only that he was not "consistently candid in his communications with the board, hindering its ability to exercise its responsibilities." The board named Mira Murati, OpenAI's Chief Technology Officer, as interim CEO. In response, OpenAI's now-former president, Greg Brockman, announced he was stepping down too, tweeting, "Sam and I are shocked and saddened by what the board did today."
