xAI Loses Two Chinese Tech Leaders Within 48 Hours Amid Founder Exodus

In the wake of xAI's announced $125 million acquisition from SpaceX, the company is experiencing a rapid exodus of its core founding team. Within 48 hours, Tony Wu, head of the reasoning organization and directly reporting to Elon Musk, and Jimmy Ba, head of research, safety, and enterprise affairs, both resigned, accounting for half of the original 12-founder group. With Wu's departure, Guodong Zhang, who oversaw pre-training, has been elevated and now leads post-training efforts. Remaining founders include Guodong Zhang and Zihang Dai. Ethan He, a current team member, has posted job openings emphasizing a non-political culture and a preference for agile, technical teams. The attrition reflects "Musk Exhaustion," with reports of 120-hour workweeks and pressure to outpace OpenAI and Anthropic. The firm also faces scrutiny over Grok's image-generating capabilities, including a French criminal investigation, and challenges in user growth for its MacroHard project and AI companion product.
