xAI·Grok family

Grok 4.6

proprietaryReleased Aug 2026

xAI's model building on Grok 4.5 with a focus on long-running agents and ambitious interactive and visual work. Sustains complex multi-step tasks across research, analysis, and whole codebases, and shows more self-testing and verification on long trajectories. Reaches frontier intelligence across agentic coding and knowledge work benchmarks, matching GPT-5.6 Sol on the Artificial Analysis Intelligence Index, and produces notably stronger first passes on visual and interactive projects. Trained with agentic RL across kernel optimization, web development, and computer-aided design, with real-time information access and an OpenAI-compatible API.
