SpaceXAI loses 50+ researchers after merger with xAI
Over 50 top researchers and engineers have left SpaceXAI since February, with key teams shrinking.
SpaceXAI, Elon Musk's newly rebranded AI company formed by merging SpaceX and xAI, is experiencing a significant talent exodus. According to The Information, over 50 researchers and engineers have left since February, including key leaders across coding, world models, and Grok voice. The departures have been particularly acute in the pre-training team, which is responsible for the foundational step of building new AI models. At least 11 former xAI employees have joined Meta, while seven have moved to Thinking Machine Labs, the startup founded by former OpenAI CTO Mira Murati. The pre-training team's lead, Juntang Zhuang, also departed, leaving the team with only a handful of members.
Sources cited by The Information attribute the departures to multiple factors. Musk's culture of extreme work and unrealistic deadlines for training models led some staff to cut corners on Grok, the company's flagship chatbot. Others may have left to cash out their equity, given SpaceX's regular tender offers and blockbuster IPO expectations. The talent drain raises serious questions about SpaceXAI's ability to compete in frontier AI development, as rivals like Meta and emerging startups aggressively recruit its former researchers. TechCrunch has reached out to SpaceX for comment.
