xAI is Elon Musk's venture into the world of artificial intelligence, and like all things Musk, it's going big. Its setting out to build AI that helps humanity understand the universe and its starting with Grok, its conversational AI chatbot already integrated into X (formerly Twitter). With access to real-time data and a powerful ecosystem of Musk-led companies, xAI is certainly pushing towards artificial general intelligence at serious scale.
