Grok 4.7: xAI's Frontier Coding and Knowledge Work Model with New Safeguard Stack and Longer RL Training
On September 21, 2026, xAI released Grok 4.7 — a new frontier model built on a larger base with a longer reinforcement learning run weighted toward multi-hour tasks. At $2/$6 per million tokens (same as Grok 4.6), it scores 46.3% on CursorBench 4.0 (vs. 40.4% for 4.6), 71.0% on DeepSWE v1.1, 64.0% on EEBench, and 19.6% on Harvey Legal Agent, while introducing an entirely new safeguard stack that tops LatchBio's biosafety benchmark at 62.4% and achieves 3.3% dual-use pass rate on HackerBench v0.3. With 500K context, configurable reasoning up to xhigh, and encrypted reasoning on the Responses API, Grok 4.7 positions xAI as a serious contender in the frontier coding and knowledge work race.
