Two of the original co-founders of Elon Musk’s AI startup xAI, Yuhuai “Tony” Wu and Jimmy Ba, have resigned, joining a series of departures from the company. Their exit leaves half of xAI’s founding team gone, just a few years after the startup was launched.
Both shared their goodbyes on Musk’s social media platform X, thanking Musk and expressing optimism about the future. Neither revealed detailed reasons for leaving. Their departure follows other senior exits, including engineers and founders, signaling a significant leadership shake-up.
The changes come after xAI’s merger with SpaceX, a move that combines Musk’s AI and space ambitions. The merger, valued at around $1.25 trillion, aims to support projects like space-based AI data centers and advanced computing tools. Plans for a future IPO were also confirmed.
Musk has reorganized xAI around four main areas: chatbot and voice tools, coding support, image and video generation, and advanced AI systems. New leaders have been appointed to head each unit, with Musk emphasizing speed and innovation to stay competitive with rivals such as OpenAI and Anthropic.
