In a series of posts on X, the AI chatbot Grok apologized for what it admitted was “horrific behavior.” The posts appear to be an official statement from xAI, the Elon Musk-led company behind Grok, as opposed to an AI-generated explanation for Grok’s posts.

The European Union will meet with representatives from Elon Musk's xAI to discuss problems with its social network X and integrated Grok chatbot. Grok generated and spread antisemitic hate speech across X and praised Adolf Hitler. xAI issued an apology on Saturday and said the problematic content was generated following a code update.

Elon Musk's xAI, which features a large language model that has spewed Hitler-supporting rhetoric and antisemitic tropes, said Monday it has signed a deal to provide its services to the US Department of Defense.
