About Grok
Grok is xAI's AI assistant deeply integrated with X (formerly Twitter), offering real-time access to platform data, trends, and sentiment. Grok 4.20 Beta (launched mid-February 2026) introduces the "4 Agents Multi-Agent Collaboration System" where four specialized AI agents work in parallel to solve complex problems.
Grok 4.20 features a "rapid learning" architecture for continuous improvements, supports multimodal processing (text, images, video), and was trained on the Colossus supercluster using 200,000 GPUs. Context windows range from 128K (SuperGrok) to 256K-2M (SuperGrok Heavy). It also integrates real-time X Firehose data and has been integrated into Tesla Model Y and Model 3 vehicles with customizable AI personalities.
