SpaceXAI, after merging with xAI in February, has seen over 50 key researchers and engineers leave, with many joining rivals Meta and Thinking Machine Labs, citing unrealistic deadlines and extreme work culture. The exits, reported by The Information, include key leaders across coding, world models, and Grok voice, leaving the core pre-training team severely depleted.

Rivals like Meta and Thinking Machine Labs are reportedly scooping up former staff, with at least 11 xAI employees defecting to Meta and at least seven to Thinking Machine Labs. TechCrunch previously reported on 11 departures announced after the merger, including two co-founders.

The pre-training departures, following team lead Juntang Zhuang’s exit, have particularly concerned employees and those close to SpaceXAI, questioning the company’s commitment to leading AI model development. A source cited Musk’s extreme work culture, including unrealistic model training deadlines, leading to corner-cutting on Grok.

Some exits might be driven by the desire to cash out via SpaceX’s regular share tender offers or anticipation of the company’s blockbuster IPO. Once employees see financial upside, they’re less inclined to stay amidst pressure and doubts about the company’s AI leadership.

TechCrunch has reached out to SpaceX for comment.
