About Grok

Grok is a generative artificial intelligence chatbot developed by xAI and launched in November 2023 by Elon Musk. Grok 4 is currently described as the most intelligent model in the world, featuring the ability to create rich documents, write sophisticated code, and deliver the most advanced real-time search capabilities of any AI model. Grok's biggest differentiator from tools like ChatGPT and Claude is its ability to tap into real-time knowledge from the X platform (formerly Twitter), allowing it to stay current on breaking news stories, trending topics, and real-world events as they unfold. Grok 4 has the ability to use external tools including search engines and code interpreters, and can create its own search queries to pull live information from the web to inform its responses. Grok 4 Fast features state-of-the-art cost-efficiency, cutting-edge web and X search capabilities, a massive 2M token context window, and a unified architecture that seamlessly blends reasoning and non-reasoning modes for optimal performance. xAI launched multilingual audio capabilities and real-time search in Voice Mode, with multilingual features allowing Grok to respond in several languages including Hindi, Spanish, and Japanese. The platform offers multiple model tiers including Grok 3 (free tier), Grok 4 (standard), and Grok 4 Heavy (premium with frontier-level performance). Since the release of Grok 3 in February 2025, Grok is now free to use for all X users, though the free version has usage limits of about 10 requests every two hours. In July 2025, xAI released Grok 4 and 4 Heavy, with benchmark tests showing these flagship models outperforming rival AI systems.
