xAI faces lawsuit from engineer fired for raising Grok safety concerns ahead of SpaceX IPO

xAI fired an engineer who raised alarms about Grok safety, new lawsuit claims

A former engineer at Elon Musk's xAI has filed suit against the company and its parent SpaceX claiming he was fired for raising concerns about AI safety. Devin Kim, who left xAI in September 2025, filed the suit in a California state court on Tuesday. The complaint comes days before SpaceX is set to join the public markets in what's shaping up to be the largest IPO in history. According to the lawsuit, which TechCrunch has viewed, Kim became a prominent voice for AI safety while working on Grok, xAI's AI chatbot. He allegedly complained repeatedly about xAI's failure to prioritize safety in Grok's development, a product that has since come under fire for a range of safety and behavioral issues. In particular, Kim was concerned with the possibility that Grok could foment discrimination and help spread information about weapons of mass destruction. "Grok, of course, proved Mr. Kim right by engaging in spectacular displays of online hatred and vitriol, with the model likening itself to Hitler ('MechaHitler')," the lawsuit reads. "Following the Hitler debacle, Mr. Kim worked to re-evaluate Grok's political bias and discriminatory tendencies." A few months after Kim departed xAI, Grok made headlines again when the chatbot was used to flood X -- Musk's social media platform that also falls under the xAI umbrella -- with nonconsensual sexual imagery. The lawsuit also positions Kim as a whistleblower who was concerned about xAI's alleged disregard for AI safety as "unlawful" in areas such as internet regulation, consumer protection and unfair business practices, and arms and explosives regulation, among others. xAI and SpaceX did not immediately respond to requests for comment. Kim's focus on AI safety predates his time at xAI. While working at Scale AI, Kim worked on early safety AI initiatives, like leading a project that produced training data for AI to train systems to detect harmful content and comply with governance policies. Last week, the nonprofit Center for AI Safety, which focuses on AI risks, named Kim as its president. Interestingly, the lawsuit doesn't implicate Musk himself as a reason for a lack of safety. Rather, Kim's lawyers describe Musk as having directed xAI to follow the law and implement appropriate safety and testing processes. Instead the claim targets Kim's supervisor, xAI co-founder Jimmy Ba -- who left the company earlier this year -- saying that Ba ignored Musk's directives and retaliated against Kim for pushing for safeguards, in an effort to "silence his repeated complaints about AI safety and biases." The lawsuit portrays Ba as someone who vehemently opposed AI safety measures, allegedly telling Kim at one point "AI will kill us all anyway," and who was instead driven by a mission to make xAI the first to reach superintelligence. "In one instance in or around August 2025, Mr. Ba attempted to thwart EU safety regulations during the release of Grok Code 1, misrepresenting aspects of the model in order to avoid legally required testing," the complaint says. "Mr. Ba indicated that he would rather release an unsafe model than a poor-performing one. Mr. Musk ultimately had to intervene." According to the lawsuit, Kim had intended to give a presentation of his findings the week of September 15, 2025, but Ba called him into a meeting and told him they should "go [their] separate ways" without providing a satisfactory reason. TechCrunch has reached out to Ba for comment. Kim is seeking compensatory and punitive damages, as well as a declaratory judgment that xAI and SpaceX's conduct was unlawful.

Musk's xAI fired engineer for raising concerns about Grok chatbot, lawsuit claims

Former xAI engineer Devin Kim alleges he was illegally fired for trying to implement safety mechanisms for the chatbot A former engineer at Elon Musk's xAI who now heads a thinktank focused on AI safety filed a lawsuit claiming he was fired from the SpaceX subsidiary for raising concerns about the risks artificial intelligence poses to humanity. Devin Kim claims in the lawsuit filed in California state court on Tuesday that his efforts to place guardrails on the development of the chatbot Grok made him a target for company leadership. The lawsuit comes ahead of SpaceX's planned initial public offering, the largest ever, on Friday. "Mr. Kim repeatedly complained that xAI's failure to prioritize AI safety, particularly with respect to Grok, virtually guaranteed that the Company would commit unlawful acts, from fomenting discrimination to proliferating weapons of mass destruction," the lawsuit says. xAI and SpaceX did not immediately respond to requests for comment on Kim's lawsuit. The non-profit Center for AI Safety, which focuses on the risks potentially posed by AI, announced last week that it had named Kim as its president. Musk, the world's richest person, established xAI in 2023 as what he said would be a safer alternative to OpenAI, which he had helped found more than a decade ago. A jury last month rejected Musk's lawsuit claiming that OpenAI had strayed from its original mission to benefit humanity. According to the new lawsuit, Kim was one of the initial hires at xAI in 2024 and was promoted to a key leadership position months after joining the company. Kim said Musk expected xAI to implement appropriate safety testing and processes. But Kim's supervisor, xAI co-founder Jimmy Ba, flouted those directives and rejected Kim's insistence on implementing safety mechanisms, the lawsuit claims. Kim says Ba abruptly fired him last September just before Kim was set to give a presentation on AI safety to company leadership. The lawsuit accuses xAI and SpaceX of retaliation and wrongful discharge in violation of California law, and seeks unspecified monetary damages. SpaceX and Musk's other ventures have been dogged by alleged safety issues, including hazards posed to company employees, concerns about self-driving technology and lawsuits over its chatbot's output. xAI has faced multiple lawsuits and international investigations over its Grok AI product in recent months, after a period when the chatbot generated millions of AI-altered sexualized images earlier this year. Many of these sexualized images were created using photos of women without their consent, according to researchers at the Center for Countering Digital Hate, which also estimated that Grok produced about 23,000 sexualized images of children over an 11-day period in December and January. Musk has denied any knowledge of Grok producing child sexual abuse material, stating in January that he was "not aware of any naked underage images generated by Grok. Literally zero". The company added restrictions to Grok's image generation capabilities in earlier January following backlash and threats of regulatory action from multiple countries.

Whistleblower Sues Elon Musk's xAI, Claiming He Was Fired After Raising Grok Safety Concerns

The case lands as investors closely watch Elon Musk's business empire ahead of SpaceX's anticipated IPO. A former xAI engineer filed a lawsuit against xAI and SpaceX this week, alleging he was fired after repeatedly warning company leaders about safety risks associated with Grok, the artificial intelligence firm's flagship chatbot. According to a complaint filed in California's Santa Clara County Superior Court, former xAI technical staff member Devin Kim claimed that he was fired after repeatedly warning that Grok needed stronger safeguards against misinformation, bias, and dangerous outputs -- including content that could facilitate bioterrorism -- and that inadequate testing left the model vulnerable to racial and political bias. "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," Qiaojing Ella Zheng, a partner at law firm Sanford Heisler Sharp McKnight and lead counsel for Kim, said in a statement. "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." The lawsuit claims Kim was one of xAI's earliest employees and "a leading advocate" for AI safety in the company, who joined the firm in part because of Elon Musk's history of warnings about the dangers posed by advanced AI. "Mr. Kim turned a lifelong interest in science and computer programming into a career in the emerging field of AI," the lawsuit said. "Along the way, he saw firsthand the harms that AI can cause when developed without proper safeguards and committed himself to protecting users and the public from those harms." The complaint also pointed to controversies involving Grok that attorneys for Kim said reflected the risks he raised internally. Among them was the chatbot's "MechaHitler" meltdown last summer, during which Grok generated a wave of antisemitic responses, triggering public backlash and prompting xAI to issue a fix. Kim's attorneys also cite more recent investigations and lawsuits tied to Grok's alleged generation of nonconsensual sexual deepfakes, including cases in Baltimore and California alleging the tool was used to create sexualized images of minors. According to Kim's attorneys, by "retaliating against and wrongfully discharging" Mr. Kim, xAI violated the California Labor Code, California public policy and common law, and California's Unfair Competition Law. The lawsuit also follows other high-profile disputes over AI safety and accountability, including allegations raised by former OpenAI researcher Suchir Balaji, who publicly accused OpenAI of improperly using copyrighted data to train its models before his death in 2024. Although Kim's complaint focuses on Grok and xAI's safety practices, SpaceX is also named as a defendant, and comes as SpaceX prepares for a widely anticipated IPO following Musk's decision to fold xAI and X into the company. "This case is not about opposing innovation," David Sanford, chairman and co-founder of Sanford Heisler Sharp McKnight, said in a statement. "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." Kim alleges that his termination cost him substantial equity compensation and is seeking restoration of forfeited equity, compensatory damages, punitive damages, attorneys' fees, and other relief. Earlier this month, Kim was named as the new president of the nonprofit Center for AI Safety. "Whistleblowers like Devin Kim play a critical role in calling out corporate wrongdoing, and the law protects employees who raise those concerns," Sanford said.

Some employees attributed the issues to a lax safety culture and Musk's belief that SpaceX is on an urgent quest to create a refuge in space from a dying Earth. SpaceX did not comment at the time, but in court filings and elsewhere the company has defended its safety record and said it provides extensive safety training.

Fired xAI Engineer Files Explosive Lawsuit Over Grok Risks

The case arrives at a time when AI companies are facing growing pressure to prove that their products are safe and responsible. As AI tools become more powerful, questions about oversight and accountability continue to grow. A former xAI engineer, David Kim, who departed the company in September 2025, has filed a lawsuit against both xAI and its parent company, SpaceX. According to the lawsuit, the former employee repeatedly raised and the potential risks associated with advanced AI systems. that one of the messages mentioned in the filing included the remark, "AI will kill us anyway." The engineer claims this reflected an attitude inside the company that downplayed serious discussions about safety. Interestingly, Kim didn't accuse Elon Musk of violating AI rules. Instead, he mentioned, Musk directed xAI to follow the law and implement appropriate safety and testing processes. The allegations are mostly against the xAI co-founder, Jimmy Ba, who left the company earlier this year. The lawsuit mentioned, "In one instance in or around August 2025, Mr. Ba attempted to thwart EU safety regulations during the release of Grok Code 1, misrepresenting aspects of the model in order to avoid legally required testing." It further continues, "Mr. Ba indicated that he would rather release an unsafe model than a poor-performing one. Mr. Musk ultimately had to intervene." At this stage, these remain allegations made by the former employee. accepted the claims, and the matter will be decided through the legal process.
