Public story · 2026-02-17 · source-backed
xAI launched Grok 4.20 Beta with a novel 4-agent collaboration system: Grok (coordinator), Harper (fact verification), Benjamin (technical analysis), and Lucas (creative input). Unlike sequential orchestration, all four agents process every query in parallel and engage in internal discussion before presenting unified responses. 2M token context window. Available to SuperGrok and X Premium+ subscribers. This is the first multi-agent-by-default architecture from a frontier lab — every query automatically gets multi-perspective processing.
