Stop chatting with a single model; start consulting a council. Grok 4.2 introduces a native multi-agent architecture where four experts: Grok (Coordinator), Harper (Research), Benjamin (Logic/Code), and Lucas (Creative) work in parallel. They cross-check facts and debate conclusions in real-time before you see the answer. Built for "rapid learning," Grok 4.2 iterates weekly based on your feedback, slashing error rates to just 4.2% while staying an order of magnitude faster.
