Grok, a generative AI chatbot created by xAI (Elon Musk’s venture), is developed by the company. Grok, which debuted in November 2023, aims to deliver insightful and humorous replies while setting itself apart with a rebellious character. It incorporates real-time web searches, image generation, PDF summarization, and sophisticated reasoning abilities. The newest iteration, Grok-3, which came out in February 2025, features improved problem-solving abilities and surpasses several rivals in benchmark tests. Grok can be accessed through the web, iOS, and Android platforms, and is integrated into services such as X (formerly Twitter) and Telegram, with the goal of making advanced AI tools widely accessible.
