xAI

Profile Overview

xAI is an artificial intelligence startup founded in July 2023 by Elon Musk, with the stated objective to "understand the true nature of the universe." Based in Austin, Texas, the company operates in close collaboration with Musk's other ventures, including Tesla, SpaceX, and X (formerly Twitter). xAI's flagship product is Grok, a conversational assistant integrated directly into X for premium subscribers. Grok is characterized by its real-time access to the platform's data stream and a conversational mode that can answer questions with wit and a rebellious streak. xAI has focused on rapid engineering execution, constructing the Colossus GPU cluster in Memphis, Tennessee—one of the world's largest AI training supercomputers powered by 100,000 liquid-cooled Nvidia H100 GPUs. This infrastructure has accelerated the development of their models, culminating in the Grok 3 series, which excels in coding, math, and logical reasoning. xAI is also developing multimodal systems for robotics and autonomous driving in partnership with Tesla. In May 2024, xAI secured $6 billion in a Series B round led by Valor Equity Partners and Vy Capital. As of early 2026, the company's valuation has surged to $50 billion, supported by total funding of $11 billion, making it one of the fastest-growing AI startups globally.
