Sam Altman, CEO of OpenAI, faces serious allegations from former board member Helen Toner, who accuses him of creating a 'toxic culture of lying' and engaging in 'psychological abuse.' Toner revealed that the board learned about the launch of ChatGPT through Twitter in November 2022, highlighting a lack of transparency. Additionally, Altman is accused of withholding information about his financial relationship with the OpenAI Startup Fund and providing inaccurate safety information. In response to these issues, OpenAI has announced the formation of a new oversight board, which includes previously fired executives.
