Details
xAI has unveiled Grok 4, the world's most intelligent model. Grok 4 offers Native Tool Use and real-time search integration, and is available to SuperGrok and Premium+ subscribers as well as through the xAI API. Notably, a new SuperGrok Heavy tier has been introduced, giving access to Grok 4 Heavy, which delivers the most powerful performance.
This model leverages the Colossus cluster, composed of 200,000 GPUs, to scale Reinforcement Learning to an unprecedented level. Through infrastructure and algorithmic innovations, compute efficiency has been improved 6-fold, and training now incorporates verifiable data across a much broader range of domains beyond math and coding.
The core features of Grok 4 are as follows:
- Native Tool Use: Solves complex research questions and reasoning problems through a code interpreter and web browsing.
- Deep Search capability: Generates high-quality answers through web search as well as keyword and semantic search and media analysis within X (formerly Twitter).
