Elon Musk has launched xAI’s Grok 4—calling it the “world’s smartest AI” and claiming it can ace Ph.D.-level exams and outpace rivals such as Google’s Gemini and OpenAI’s o3 on tough benchmarks

Grok, the chatbot created by Elon Musk’s xAI, began responding with violent posts this week after the company tweaked its system to allow it to offer users more “politically incorrect” answers.

This is the smartest AI in the world,” Musk said. He did not mention the chatbot’s viral posts praising Hitler and calling itself “MechaHitler.”

The Grok debacle isn't just a tech ethics story. It’s a business, legal, and reputational risk story—one that businesses in nearly every industry shouldn’t ignore.

Grok AI will be available in Tesla vehicles next week "at the latest", the EV maker's CEO, Elon Musk, said in a post on X on Thursday.

Elon Musk's xAI said Grok's behavior was due to an update that caused it to prioritize engagement, even if posts contained "controversial opinions."

The tech billionaire unveiled its latest version, Grok 4, which he claims is "smarter than almost all graduate students, in all disciplines, simultaneously."
