Elon Musk’s recently rebranded artificial intelligence venture, SpaceXAI, is reportedly grappling with a significant talent drain, seeing over 50 researchers and engineers depart since February. This exodus, detailed by The Information, includes pivotal leaders across critical areas such as coding, world models, and the development of Grok’s voice capabilities.
The departing personnel are reportedly being absorbed by rival firms, with Meta and Mira Murati’s Thinking Machine Labs actively recruiting former staff. This attrition has reportedly shrunk SpaceXAI’s core pre-training team to a mere handful of individuals. According to The Information’s report, at least 11 xAI employees have moved to Meta since February, while another seven have joined Thinking Machine Labs. This follows earlier reports by TechCrunch, which highlighted 11 xAI departures immediately after the merger, including two co-founders.
The context for these shifts lies in the February acquisition of xAI by SpaceX—both entities under Musk’s ownership. Following this merger, new leadership was installed, and the combined company was officially renamed SpaceXAI earlier this month.
The departures from the pre-training division, which notably followed the exit of team lead Juntang Zhuang, have generated particular concern among employees and those closely associated with SpaceXAI, as reported by The Information. Given that pre-training constitutes the foundational stage for developing new AI models, these exits have sparked questions regarding the company’s sustained commitment to creating industry-leading models.
The report further suggests that Musk’s demanding work culture contributed to some staff departures—a recurring complaint among employees across his various companies, including Tesla. A source speaking to The Information indicated that Musk imposed "unrealistic deadlines" for model training, which consequently led to "cutting corners on Grok."
It is also plausible that a desire for financial liquidity played a role in some of these exits.
SpaceX frequently facilitates tender offers, allowing employees to privately sell vested shares. Moreover, with the company’s anticipated blockbuster IPO, many employees may feel confident that their equity is nearing liquidity. When the prospect of substantial financial gain becomes clear, employees often show less tolerance for companies imposing excessive pressure or those perceived as not developing the cutting-edge models they aspire to work on.
TechCrunch has reached out to SpaceX for comment regarding these developments.
