xAI fired an engineer who raised alarms about Grok safety, new lawsuit claims
A former xAI engineer is suing the company and SpaceX, alleging he was fired for raising AI safety concerns about Grok days before SpaceX's historic IPO.
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.”
September was my last month at xAI! I joined as one of the first members of the post-training team in 2024 and eventually led research tooling, where we built some of the world’s best systems to accelerate Grok’s development. On my first day, I was at the whiteboard with @ibab …
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 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.

Pontos-chave
- A demissão de Devin Kim destaca a importância da ética e segurança no desenvolvimento de IA no Brasil.
- O caso pode incentivar um movimento entre profissionais de tecnologia para priorizar a segurança em inovações.
- A reputação da xAI pode ser afetada, impactando a confiança do público em tecnologias de IA.
Análise editorial
A demissão de Devin Kim da xAI, em meio a preocupações sobre a segurança da IA, levanta questões cruciais sobre a ética no desenvolvimento de tecnologias emergentes. No Brasil, onde o setor de tecnologia está em rápida expansão, a discussão sobre a responsabilidade das empresas em garantir a segurança e a ética de suas inovações é cada vez mais relevante. A situação de Kim destaca a necessidade de um diálogo aberto sobre os riscos associados à IA, especialmente em um contexto onde a regulação ainda está em desenvolvimento.
Além disso, a alegação de que xAI não priorizou a segurança no desenvolvimento do Grok pode ter implicações significativas para a reputação da empresa e para a confiança do público em tecnologias de IA. No Brasil, onde as startups de tecnologia estão se proliferando, a transparência e a ética no uso de IA serão fundamentais para conquistar a confiança dos consumidores e investidores. O caso também pode incentivar outras vozes a se manifestarem sobre preocupações semelhantes, criando um ambiente mais seguro e responsável para o desenvolvimento de IA.
O fato de Kim ser um ex-funcionário que já atuou em iniciativas de segurança de IA em outras empresas, como a Scale AI, adiciona credibilidade às suas alegações. Isso pode inspirar um movimento mais amplo entre os profissionais de tecnologia no Brasil para priorizar a segurança em suas inovações. À medida que o Brasil se posiciona como um hub de tecnologia na América Latina, a necessidade de diretrizes claras e práticas de segurança em IA se torna ainda mais urgente.
Por fim, é importante observar como a situação se desenrolará, especialmente com a iminente IPO da SpaceX. O resultado deste processo legal pode influenciar a forma como as empresas de tecnologia abordam a segurança da IA e a responsabilidade corporativa, não apenas nos Estados Unidos, mas também em mercados emergentes como o Brasil, onde a regulamentação ainda está em fase de maturação.
