Grok 3 represents the most substantial advancement in AI capability since GPT-4. Built on xAI’s Colossus supercomputer with 200,000 GPUs, it introduces several groundbreaking features that set new standards for AI performance.
The model’s enhanced reasoning capabilities allow it to think through complex problems step-by-step, similar to human cognitive processes. This is achieved through a chain-of-thought mechanism that explains its reasoning before providing answers. The system also includes a “Big Brain” mode that dedicates additional computational resources to mathematical, scientific, and programming queries.
One of Grok 3’s standout features is DeepSearch, which scans the internet and X platform to deliver precise, contextual summaries within seconds. Users can narrow searches to specific websites or sources, making it a powerful research tool.
In terms of processing power, Grok 3 uses ten times more computing resources than its predecessor. This translates to faster response times and improved handling of complex tasks. The model also excels in multimodal processing, working with text, images, and soon, voice interactions.
Grok 3’s benchmark scores are particularly impressive:
– 93% accuracy on AIME 2025
– 85% correct answers on GPQA with reasoning enabled
– 80% success rate on LiveCodeBench with reasoning
– #1 ranking on LMArena with 1400 ELO
– Leading position on Chatbot Arena under the codename “Chocolate”
The model consistently outperforms competitors like GPT-4o, DeepSeek-V3, Gemini 2.0, and Claude 3.5 Sonnet in internal tests across mathematics, science, and coding.

The real impact of Grok 3 lies in its practical applications. By combining advanced reasoning with real-time data integration from X, it offers more accurate and current responses than any existing AI system. The addition of voice mode will further expand its accessibility and use cases.
