xAI released Grok 4.7 on September 21, 2026, calling it its most capable model for coding and knowledge work. It sits on a new, larger base model with a longer reinforcement learning run weighted toward multi-hour tasks, and xAI reports 46.3% on CursorBench 4.0. Pricing stays at $2 per million input tokens and $6 output, the same as Grok 4.6, with a 500K context window. It is live in Cursor, Grok Build, the API and GitHub Copilot.

xAI ships Grok 4.6, aimed at long-running agents
xAI released Grok 4.6 on August 12, 2026, built on Grok 4.5 with a focus on long-running agents and interactive or visual work — staying with a task across many steps, and self-testing its own output on extended runs. Pricing is $2 per million input tokens and $6 per million output tokens, with a faster variant at double that. xAI says it matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index.
