About Grok 3

Grok 3 is xAI's frontier AI model, trained on one of the world's largest GPU clusters (100,000 Nvidia H100s). It features real-time access to X (Twitter) data, giving it uniquely current information about world events, public sentiment, and trending topics. The model excels at coding, reasoning, and factual tasks while offering a distinctive personality that includes humor and directness. With strong performance on arena benchmarks, Grok 3 competes directly with GPT-4o and Claude Sonnet. Its differentiator is the real-time information access and willingness to engage with topics that other models may decline. Available through the xAI API and the Grok chatbot on X, it has quickly become one of the most capable models in the market.
