Grok 4.7

Grok 4.7 is an xAI language model released on 21 September 2026 and positioned by the company as its most capable model for coding and knowledge work. It is built on a larger base model trained with longer reinforcement learning; xAI emphasizes that the model works longer on difficult tasks and checks its own work more carefully. Document creation and multi-hour professional tasks improved noticeably — across legal, electrical engineering and office work.

The model runs under the API identifier grok-4.7, supports a 500,000-token context window and text plus image input, and its knowledge extends through May 2026. Base pricing is $2 per million input tokens and $6 per million output tokens; above 200,000 prompt tokens the rates rise to $4 and $12. It is available through the Grok API, Grok Build, Cursor and third-party platforms and agentic harnesses.

In figures reported by xAI, Grok 4.7 scores 64.0% on EEBench (electrical engineering, up from 53.0%), 46.3% on CursorBench 4.0 (up from 40.4%), 38.0% on Terminal-Bench 4.0 (up from 20.3%) and 19.6% on Harvey Legal Agent (up from 15.8%). On safety tests the model allows through 3.3% of risky cybersecurity prompts while keeping refusals low for legitimate use, and it reaches 62.4% on a biosafety benchmark.
