Grok 4.7 is xAI's (now branded SpaceXAI) flagship released on September 21, 2026, targeting coding, long-running agents and knowledge work. It uses a larger base model and a longer reinforcement-learning run, and xAI says it works longer on hard problems, verifies its own output more carefully, and natively understands the Grok Bot harness. The context window stays at 500K tokens with low / medium / high / xhigh reasoning effort, at the same price as Grok 4.6.
