World's Most Powerful LLM API with Native Tool Use and Real-Time Search Integration

‍

Grok 4 represents xAI's flagship large language model, launched on July 9, 2025, and positioned as the most intelligent AI model in the world. Developed by Elon Musk's xAI company, Grok 4 delivers unprecedented capabilities in reasoning, coding, and real-time information processing. It includes native tool use and real-time search integration, and is available now to SuperGrok and Premium+ subscribers, as well as through the xAI API.

As the successor to Grok 3, this flagship model features a 256K-token context window, always-on "Think" reasoning, and an optional Heavy tier that provides multi-agent problem-solving capabilities. Marketed with bold claims of PhD-level intelligence across disciplines and the ability to discover new physics within a year, Grok 4 made its debut during a livestream that attracted over 1.5 million viewers.
