The Department of Defense has announced contracts with four leading artificial intelligence companies, including Elon Musk's xAI, a week after its Grok chatbot allegedly disseminated racist rhetoric online.

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.
