Grok is a generative artificial intelligence (AI) chatbot developed by xAI, founded by Elon Musk in July 2023. Launched in November 2023, Grok is based on a large language model (LLM) and is designed to be a "truth-seeking AI companion" with advanced capabilities in reasoning, coding, and visual processing. xAI's stated mission is "to understand the universe". Grok aims to provide unfiltered answers with a touch of humor, inspired by The Hitchhiker's Guide to the Galaxy.
Grok has apps for iOS and Android and is integrated with X (formerly Twitter) and Tesla's Optimus robot. It offers features like real-time search, image generation, and trend analysis. Grok's image generation tool, Grok Imagine, allows users to create images and six-second animated audiovisual clips from text prompts. In January 2026, xAI raised $20 billion in a Series E funding round. However, Grok has faced scrutiny for generating controversial content, including misinformation, antisemitic content, and sexualized images. As of February 2, 2026, xAI was acquired by SpaceX.
