Summary
xAI has sued former employee Xu Shen Li for stealing trade secrets about Grok shortly after he accepted a job offer from OpenAI. Li took the files in July and later sold $7 million in xAI stock. During an August 14 meeting, Li admitted to taking xAI files. The company later discovered additional stolen material on his devices that he had not disclosed. xAI is seeking unspecified monetary damages and a court order blocking Li's move to OpenAI.
The lawsuit reflects a broader pattern of AI talent competition. Shengjia Jiao, co-creator of ChatGPT and head of Meta's Super Intelligence Labs, threatened to quit and rejoin OpenAI within days of starting at MSL. He had already signed employment paperwork with OpenAI. The departure signals friction at Meta's newly established AI research unit, which was built around attracting top researchers with large offers and computational resources. Meta denied reports of internal conflict, calling them "manufactured tension without basis in fact," while noting that MSL has "the greatest compute per researcher in the industry." One Meta researcher wrote on X that "one more reorg and everything will be fixed," capturing mounting skepticism about the unit's direction.
