x.ai

xAI is an artificial-intelligence company founded by Elon Musk in 2023. It builds AI systems, including large language models, with the stated aim of accelerating humanity's scientific understanding of the universe and advancing human knowledge and discovery. The firm describes its mission as creating AI that maximally benefits all of humanity, and frames its work as pushing beyond conversational systems toward genuine advances in understanding.

The company's principal product is Grok, an AI assistant modelled after the Hitchhiker's Guide to the Galaxy. Grok is designed to answer questions with a measure of wit while drawing on real-time information through the X platform. Its technical work spans large language models and generative AI, natural language processing and conversational AI, first-principles reasoning, real-time information retrieval and integration, and the application of AI to scientific discovery.

xAI operates from five offices - Palo Alto, Seattle, San Francisco, Tennessee and London - staffed by a group of researchers and engineers. Its stated operating principles centre on first-principles reasoning and rapid iteration, and wit and humour are treated as deliberate design considerations in its products. The team is geographically distributed across the United States and the United Kingdom.
