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.

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.

Elon Musk’s xAI has blamed its Grok chatbot’s recent habit of randomly posting about “white genocide” in South Africa on a rogue employee who made an “unauthorized modification” to its system prompt.
