A former engineer has filed a lawsuit against xAI and SpaceX. Devin Kim has brought the case to a California state court on Tuesday. He has claimed that the company fired him because of safety concerns. Devin worked on the AI chatbot Grok and led research tooling. Over time, he has spoken out about the dangers of the AI program. He has pointed out that Grok could help spread dangerous information. The chatbot has even put out hateful messages online. Devin has repeatedly brought up these serious issues with his supervisor, Jimmy Ba. Jimmy Ba was a co-founder of the AI company. However, Ba has turned down Devin's safety ideas to speed up development. The lawsuit has shown that Ba wanted to build superintelligence first. Ba has tried to get around safety rules in the European Union. Elon Musk has told his team to follow the law and test properly. But Ba has ignored Musk and has pushed Devin out of the company. Devin left his job in September 2025. Since then, the chatbot has caused more problems on the social media platform X. Users have created nonconsensual pictures and have flooded the site with them. Devin has decided to stand up against these unfair business practices. He has asked for money to cover the damages from losing his job. SpaceX has planned to join the public markets very soon. This lawsuit has come at a difficult time for the space company. Now, Devin has moved on to a new role in the AI industry. He has become the president of the Center for AI Safety. The court has not set a date for the trial yet. xAI and SpaceX have not responded to requests for comments.
