Grok 4.7

xAI's frontier model for coding, agentic tasks, and knowledge work: a larger base model than Grok 4.6 with extended reinforcement learning, better at verifying its own work and managing long context. 500K token context window, text and image inputs, always-on reasoning with effort control (low/medium/high/xhigh, default high). Knowledge cutoff: May 2026.
