Model Card: Grok 4.7
Grok 4.7 shipped 2026-09-21 as `grok-4.7`: a new, larger base model with longer RL training; 500K-token context window; API pricing unchanged at $2.00 input / $6.00 output per 1M tokens (rising to $4.00/$12.00 above 200K tokens). xAI's own Terminal-Bench 4.0 score jumps from 20.3% to 38.0%, but Artificial Analysis's independent re-test puts it at only 26% — well behind GPT-6 Astra (60%) and Claude Fable 5.1 (55%). It rolled out to all GitHub Copilot plans the same day. For agent builders, it's a 3-8x cheaper option for agentic coding, but complex autonomous terminal work still warrants independent benchmarking before you rely on it.
