Grok 4.7 is xAI's most capable model for coding and knowledge work. It uses a larger base than Grok 4.6, with longer training on multi-hour tasks, and it is better at checking its own work, managing long context, and the Grok Bot harness. Served at the same price and speed as Grok 4.6, with a 500K context window plus text and image input. Basics
