A federal court on Monday dismissed claims filed against OpenAI and its top executives by Elon Musk, who accused them of betraying a shared vision for it to remain a nonprofit dedicated to guiding artificial intelligence's development for the good of humanity. Musk, the world's richest man, was a co-founder of OpenAI, which launched in 2015 and went on to create ChatGPT. After investing $38 million in its first years, Musk accused OpenAI CEO Sam Altman and his top deputy of shifting into a moneymaking mode behind his back.
