A former artificial intelligence engineer at Elon Musk’s xAI is suing the company, alleging that he was wrongfully fired for raising concerns about the safety of the firm’s Grok chatbot.
In a lawsuit filed in California state court, Devin Kim claimed he repeatedly complained to his supervisors that the company was failing to prioritise safety while developing Grok. Kim says he was fired in September 2025, ahead of a planned presentation to xAI leadership about safety issues.
Kim’s claims come months after a global uproar over widespread usage of Grok to digitally undress people. Since then, regulators across Europe have sought to place limits on Grok. Some consumers, including influencer Ashley St Clair, the mother of one of Musk’s children, have sued xAI.
The company said in January that it disabled Grok’s ability to create sexualised images of real people and that it was "committed to making X a safe platform for everyone.”
In his suit, Kim said that, while working on a project, he found that Grok "tended to discriminate against certain racial groups while favouring others.” He said he flagged the observation to his supervisors in various reports. Kim said he was also concerned that Grok could give users guidance on bomb-making or creating bioweapons.
"Mr Kim believed that xAI’s disregard for AI safety was unlawful,” his lawyers said in the lawsuit. Noting the undressing scandal, they added, "Mr Kim’s concerns about xAI’s model were not only well-grounded but proved remarkably prescient.”
The complaint also names SpaceX, xAI’s parent company, which is set to have its blockbuster initial public offering on Friday. The AI unit was at the centre of the IPO’s roadshow, with Musk touting AI satellites, data centres and a frontier lab that will help him create a vertically integrated AI conglomerate.
Neither xAI nor SpaceX immediately responded to requests for comment on Kim’s suit.
Before joining xAI, Kim, who previously worked at Scale AI, claims that he spoke about AI safety with executives. During those conversations, Kim said he "highlighted the risks associated with rapidly advancing AI capabilities, and sought to understand xAI’s approach to safety and risk mitigation.”
But once he was at xAI, Kim claims his supervisor, co-founder Jimmy Ba, was dismissive of safety concerns. According to Kim, Ba didn’t follow safety directives issued by Musk.
"AI will kill us all anyway,” Ba allegedly said. Kim says it was Ba who fired him.
Ba, who didn’t immediately respond to an email seeking comment, exited the firm in February following its merger with SpaceX. Since then, all of xAI’s founding members except Musk have left along with dozens of engineers and specialists. Musk has since brought over staff from SpaceX’s Starlink unit. – Bloomberg
