“The claim of white genocide in South Africa is highly contentious and lacks credible evidence,” the Grok-powered X account replied to New York Times tech reporter Mike Isaac, who was initially inquiring about a cat video.

Elon Musk’s artificial intelligence tool Grok went haywire for users of the social media platform X on Wednesday, responding to innocuous queries about things like baseball and puppies with information on South Africa and a conspiracy theory called “white genocide.” It was widespread and extremely weird to witness.

After xAI’s chatbot Grok spent a few hours on Wednesday telling every X user that would listen that the claim of white genocide in South Africa is highly contentious, the company has blamed the behavior on an “unauthorized modification” to Grok’s code.
