Grok 4.20 Multi Agent 0309

by xAI

Grok 4.20 Multi-Agent 0309 is xAI's multi-agent coordination model from the Grok 4.20 generation, released in March 2026 and optimized for research and analytical tasks that benefit from parallel processing of information. The architecture lets you scale how many agents collaborate on a request, with standard and larger heavy configurations. Multiple agents work in parallel, cross-check conclusions, and synthesize a final answer, an approach xAI uses to reduce hallucinations relative to single-pass models. Encrypted sub-agent state, including intermediate reasoning and tool calls, can be returned when explicitly enabled, letting you preserve the full multi-agent context across multi-turn workflows. With a 1 million token context window, real-time X data integration, tool use, and structured outputs, the model is aimed at open-ended research, comparative analysis, and tasks where cross-verification across multiple reasoning paths is valuable.
