Grok 4.20 beta brings four-agent inference

This is a meaningful architectural shift, but the real test is whether multi-agent quality gains consistently beat the added latency and cost.

• –Four specialized roles (coordination, research, logic, creative) suggest better coverage of complex tasks than one-pass generation.
• –It reflects a broader trend from “bigger base model” to inference-time orchestration and debate.
• –If this works reliably in production, it could reduce dependence on external agent frameworks for many users.
• –Competitive pressure will rise on other frontier chatbots to ship native multi-agent modes, not just tool wrappers.
