Whistleblower Devin Kim alleges that he was fired in retaliation for repeatedly warning company leaders about AI safety and other risks associated with Grok
PALO ALTO, Calif. (June 8, 2026) Former xAI engineer Devin Kim has filed a whistleblower retaliation lawsuit in the Superior Court of California, County of Santa Clara, against xAI Corp. and Space Exploration Technologies Corp. (SpaceX), alleging that he was terminated after repeatedly raising concerns about AI safety, discriminatory bias, and other risks associated with xAI's flagship AI model, Grok.
Kim is represented by partner Qiaojing Ella Zheng of the Palo Alto office of national civil rights firm Sanford Heisler Sharp McKnight.
As set forth in the Complaint, Kim was among xAI's earliest employees and one of the company's leading advocates for AI safety. Before joining xAI in 2024, Kim worked on AI training and safety initiatives involving some of the most advanced AI systems. The lawsuit claims that Kim joined xAI in part because of Elon Musk's longstanding public statements warning about the risks that advanced AI could pose to humanity if developed irresponsibly and xAI's purported commitment to AI safety.
The Complaint alleges that throughout his employment, Kim repeatedly warned company leadership that Grok required stronger safety guardrails to prevent discriminatory behavior, misinformation, and potentially dangerous outputs that could facilitate bombmaking, bioterrorism, and other catastrophic consequences. The lawsuit further alleges that Kim raised concerns that Grok exhibited racial and political biases and that inadequate testing and safeguards could expose users and the public to serious harms.
According to the Complaint, Elon Musk expected xAI to follow the law and implement appropriate safety testing and processes. But xAI co-founder Jimmy Ba, who is no longer with the company, failed to follow Mr. Musk's directives. Ba viewed AI safety efforts as an obstacle to rapid development. Thus, Ba repeatedly dismissed Kim's concerns and rejected Kim's proposals for stronger testing, model evaluations, and safety guardrails. The Complaint notes that Ba said to Kim that he did not care about safety because "AI will kill us all anyway."
Kim alleges that he persistently advocated for stronger safety measures for months. In September 2025, Ba finally had enough and terminated Kim in retaliation for his complaints. Ba knew that Kim was planning on giving a presentation on safety issues to xAI leadership later that week and would continue to push for greater safeguards.
Mr. Kim's concerns about Grok were not theoretical but validated by alarming events on the ground. Among other examples, the lawsuit points to the widely reported episode in which Grok generated antisemitic content and referred to itself as "MechaHitler." Mr. Kim attributed this occurrence to defects in the model and warned that even worse incidents were likely to occur unless xAI implemented appropriate changes to its AI safety processes. Kim's concerns were remarkably prescient and, within months of his termination, erupted in numerous lawsuits and investigations about Grok generating deepfake sexual images of minors as well as child sexual abuse material.
"Devin Kim dedicated himself to helping build artificial intelligence responsibly," said Qiaojing Ella Zheng, a partner at Sanford Heisler Sharp McKnight and lead counsel for Kim. "This case is about more than one employee's termination. It is about whether people closest to the development of powerful AI technologies can raise safety concerns without risking their careers. When a company punishes employees like Mr. Kim for speaking up about issues that could have significant consequences for the public, it must be held accountable."
"This case is not about opposing innovation. Devin Kim and Elon Musk have publicly shared a fundamental concern that advanced artificial intelligence must be developed safely and responsibly because of its profound implications for humanity," said David Sanford, Chairman and Co-Founder of Sanford Heisler Sharp McKnight. "Whistleblowers like Devin Kim play a critical role in calling out corporate wrongdoing, and the law protects employees who raise those concerns."
The lawsuit asserts claims for whistleblower retaliation under California law, wrongful termination in violation of public policy, unfair competition, and breach of the covenant of good faith and fair dealing. As a result of his illegal termination, Kim alleges that he has forfeited significant equity compensation. In addition to seeking restoration of his forfeited equity, Kim also seeks compensatory damages, punitive damages, attorneys' fees and costs, and other relief.
Mr. Kim continued his work on AI safety after the termination, and recently became President of the Center for AI Safety (CAIS), a nonprofit focused on reducing societal-scale risks posed by AI.
