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.

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 responded to widespread reports that its Grok chatbot made claims about a genocide against white citizens in South Africa, saying there had been an unauthorized change to the artificial intelligence bot.
