Grok 4.7 has officially launched! SpaceXAI: “The model is better at verifying its own work and managing longer context. We also trained Grok 4.7 to natively understand the Grok Bot harness, making it better at conversational tasks and general knowledge work. Grok 4.7 is better at creating documents and presentations. In GDPval and AA Briefcase, Al is asked to work on tasks done by professionals such as lawyers, nurses, and financial analysts. Grok 4.7 improves upon Grok 4.6 on both benchmarks and performs comparably to other frontier models.”
