Elon Musk's artificial intelligence company, xAI, says an “unauthorized modification” led its Grok chatbot to post unsolicited claims on social media about the persecution and “genocide” of white people in South Africa.

Reuters, the news and media division of Thomson Reuters, is the world’s largest multimedia news provider, reaching billions of people worldwide every day. Reuters provides business, financial, national and international news to professionals via desktop terminals, the world's media organizations, industry events and directly to consumers.

Some X users on Wednesday asked Grok – the AI chatbot available through Elon Musk’s social media platform – questions about simple topics like baseball players or videos of fish being flushed down toilets.
