xAI releases Grok 4.7, its most capable coding and knowledge-work model
xAI
xAI (SpaceXAI) launched Grok 4.7 on Sep 21, positioning it as 'our most capable model for coding and knowledge work', with a larger base model, longer RL training, improved self-verification, and long-horizon processing that lets it work autonomously for hours. Priced at $2/$6 per million input/output tokens, unchanged from Grok 4.6 and well below rivals; available day-one in Cursor, Grok Build, the Grok API, GitHub Copilot and Devin. Independent benchmarks are mixed: coding gains over GPT-5.6 Sol, but most aggregate benchmarks still trail Claude and GPT-6.
