The Pentagon has signed a multi-million dollar deal to begin using Elon Musk's artificial intelligence chatbot, Grok, as part of a wider rollout of AI tools for government use, the Department of Defence confirmed.

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.

Grok, the artificial-intelligence chatbot produced by Elon Musk -owned xAI, this week began posting antisemitic messages in response to user queries, drawing condemnation from Jewish advocacy groups and raising concern about the AI tool. The antisemitic posts -- some of which have been deleted -- are being addressed, Musk said on Wednesday.
