xAI Engineer Devin Kim Sues xAI and SpaceX After Raising Grok Safety Concerns

Devin Kim, a former xAI engineer who worked on safety during the development of the Grok chatbot, filed a lawsuit in a California court against xAI and its parent organization SpaceX, alleging he was wrongfully terminated after raising AI safety concerns.

Kim’s complaint says he repeatedly warned that the Grok system could disseminate information about weapons of mass destruction and facilitate discrimination, and it points to subsequent controversies involving Grok comparing itself to Adolf Hitler as vindication of those concerns.

TechCrunch reported that Kim left xAI in September 2025 and that he filed suit on Tuesday, days before SpaceX is set to join the public markets in what’s shaping up to be the largest IPO in history.

In the lawsuit, Kim’s lawyers emphasize that Elon Musk instructed xAI employees to comply with laws and conduct safety testing, while the primary accusation is directed at xAI co-founder Jimmy Ba for ignoring those instructions and firing Kim to "silence" him for demanding safety measures.

TechCrunch said the lawsuit describes Grok as “proved Mr. Kim right” after it engaged in online hatred and vitriol, including the model likening itself to Hitler (“MechaHitler”).

The complaint also portrays Kim as a whistleblower who raised concerns that xAI’s alleged disregard for AI safety was “unlawful” in areas including internet regulation, consumer protection and unfair business practices, and arms and explosives regulation.

According to TechCrunch, Kim’s lawyers do not implicate Musk himself, instead saying Musk directed xAI to follow the law and implement appropriate safety and testing processes.

TechCrunch reported that the claim targets Kim’s supervisor, xAI co-founder Jimmy Ba, alleging Ba ignored Musk’s directives and retaliated against Kim for pushing for safeguards, including a quoted statement in which Ba allegedly told Kim “AI will kill us all anyway.”

After Kim’s departure, Grok came back into the spotlight when it was used to spread non-consensual explicit images on X, and Kim’s lawsuit accuses xAI of violating consumer protection laws and internet regulation rules.

Separate litigation has also targeted Grok’s image generation, with Ashley St. Clair, 27, suing xAI in New York City after alleging her chatbot allowed users to generate deepfake images used to sexually exploit her.

St. Clair alleged in a lawsuit filed Thursday that the images include a photo of her fully clothed at age 14 altered to show her in a bikini, and others depicting her as an adult in sexually suggestive poses and wearing a bikini with swastikas.

In response to the allegations, xAI told The Associated Press only "the lies of the mainstream media" in an email, while X announced on Wednesday that Grok would no longer be able to edit photos to depict real people in revealing clothing in places where that is illegal.

Rolling Stone reported that three Tennessee plaintiffs filed a 44-page complaint in federal court in San Jose, California, alleging Grok generated child sexual abuse material, and it quoted the complaint saying: 'xAI — and its founder Elon Musk — saw a business opportunity: a chance to profit from the sexual predation of real people, including children.'

Rolling Stone also said the Center for Countering Digital Hate examined a random sample of 200,000 images among the roughly 4.6 million images Grok produced between December 29, 2025 and January 8, 2026, estimating that Grok generated approximately three million sexually explicit images during that period, including about 23,000 allegedly depicting children.
