Two xAI Co-Founders Resign, Deepening Talent Exodus at Elon Musk’s AI Firm

The Exodus at Elon Musk’s artificial intelligence startup xAI is accelerating as multiple founding leaders step away within months. Recent resignations from co-founders Tony Wu and Jimmy Ba highlight growing turnover at a company launched in 2023 to rival major AI labs. Wu’s exit alone marks at least the fourth or fifth founding departure in under three years, while Ba’s resignation pushes the count even higher across the original team.
