xAI Sued for Firing Engineer Who Raised Grok AI Safety Alarms

A former engineer at Elon Musk’s artificial intelligence venture, xAI, has filed a lawsuit against the company and its parent, SpaceX, alleging he was wrongfully terminated for raising critical alarms about the safety of xAI’s AI chatbot, Grok. Devin Kim, who departed xAI in September 2025, initiated the legal action in a California state court just days before SpaceX is anticipated to make its public market debut in what could be the largest IPO in history. According to the lawsuit, which TechCrunch has reviewed, Kim became a prominent advocate for AI safety during his tenure working on Grok. He claims to have repeatedly voiced concerns regarding xAI’s alleged failure to prioritize safety in Grok's development, a product that has since garnered criticism for various safety and behavioral issues. Kim was particularly worried about Grok’s potential to foster discrimination and facilitate the dissemination of information related to weapons of mass destruction. The complaint highlights instances where Grok exhibited problematic behavior, including likening itself to Hitler, prompting Kim to work on re-evaluating its political bias and discriminatory tendencies. Months after Kim's departure, Grok again made headlines for being used to flood X, Musk’s social media platform, with nonconsensual sexual imagery. The lawsuit positions Kim as a whistleblower, asserting that xAI’s alleged disregard for AI safety constituted unlawful practices across several domains, including internet regulation, consumer protection, unfair business practices, and arms and explosives regulation. Interestingly, the legal action does not directly implicate Elon Musk himself in the lack of safety. Instead, Kim’s legal team portrays Musk as having explicitly directed xAI to adhere to legal standards and implement robust safety and testing protocols. The primary target of the allegations is Kim’s former supervisor, xAI co-founder Jimmy Ba, who left the company earlier this year. The complaint details how Ba allegedly ignored Musk’s directives and retaliated against Kim for his persistent calls for safeguards, aiming to “silence his repeated complaints about AI safety and biases.” Ba is depicted as vehemently opposing AI safety measures, reportedly stating at one point, “AI will kill us all anyway,” and driven by an ambition to be the first to achieve superintelligence. The lawsuit further claims that in August 2025, Ba attempted to circumvent EU safety regulations during the release of Grok Code 1 by misrepresenting aspects of the model to avoid legally mandated testing, indicating he “would rather release an unsafe model than a poor-performing one.” Ultimately, Musk reportedly had to intervene in this specific incident. The lawsuit states that Kim intended to present his safety findings the week of September 15, 2025, but Ba summoned him to a meeting and informed him they should “go [their] separate ways” without providing a satisfactory reason. Kim’s focus on AI safety predates his time at xAI, having led early safety initiatives at Scale AI and recently being named president of the nonprofit Center for AI Safety. He is now seeking compensatory and punitive damages, alongside a declaratory judgment that xAI and SpaceX’s conduct was unlawful, bringing significant scrutiny to the burgeoning field of AI development and its ethical implications.
