AI Model

Grok-4.20, released by xAI in early 2026, is a high-speed, 2-million-token context, agentic AI model designed for complex reasoning, real-time tool calling, and low-latency interaction. It operates as a multi-agent system, frequently utilizing four specialized agents that collaborate to reduce hallucinations and improve accuracy, particularly for coding, research, and data processing.
