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

‍

Grok 4 is xAI's main large language model, launched on July 9, 2025. It is claimed to be the smartest AI model in the world. Developed by Elon Musk's xAI company, Grok 4 offers remarkable abilities in reasoning, coding, and processing information in real time. It features built-in tool use and real-time search integration. Currently, it is available to SuperGrok and Premium+ subscribers, as well as through the xAI API.

As the successor to Grok 3, this model has a 256K-token context window, always-on "Think" reasoning, and an optional Heavy tier for multi-agent problem-solving. It was promoted with bold claims of PhD-level intelligence across various fields and the potential to uncover new physics within a year. Grok 4 made its debut during a livestream that drew over 1.5 million viewers.

Grok 4's unique design makes it the top choice for applications that need real-time data access, strong reasoning, and smooth tool integration in production settings.
