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.

“These models will have all the service level agreements (SLAs) Azure customers expect from any Microsoft product,” says Microsoft. The Grok AI models will be hosted and billed directly by Microsoft, and offered to its own product teams and customers through its Azure AI Foundry service.
