X’s AI chatbot Grok 4 is now free for all users globally, opening access to the company’s most advanced model yet. Users can experience it in Auto mode, where the system automatically routes complex queries to Grok 4, or switch to Expert mode to ensure the high-end model is used for every request.
The move significantly lowers the entry barrier for users who previously faced paywalls or tiered access, potentially boosting engagement on Elon Musk’s social platform. By making Grok 4 widely available, X is positioning itself to compete more aggressively with established AI players like OpenAI’s ChatGPT, Anthropic’s Claude, and Google’s Gemini.
For now, X is offering “generous usage limits” so users can explore the model’s full potential without worrying about strict caps. While details on future pricing or restrictions remain unclear, the free rollout appears aimed at showcasing Grok 4’s capabilities to a broad audience — from casual users to developers and power users.
Grok, first launched in late 2023, has evolved into X’s flagship AI assistant, integrated directly into the platform. The latest version, Grok 4, promises faster response times, better reasoning, and more reliable answers across diverse topics, from coding help to creative writing.
Making Grok 4 free could also serve as a testing ground for scaling the model under real-world usage. If uptake is strong, it could accelerate X’s AI ambitions while offering users a competitive alternative to subscription-based AI services.
