Here is GROK's explanation of how GROK works:
There isn't a tiny newsroom of four conscious people living inside the model. What's publicly described—especially around the Grok 4.20 multi-agent line, and later in official "4 or 16 agents" research modes—is a software process that imitates an editorial desk.
One role (often called the captain or leader) breaks a question into pieces and writes the answer you actually see. Another is biased toward fetching and checking current sources. Another is biased toward step-by-step logic, numbers, and code. Another is biased toward alternatives, weak spots, and "what if we're wrong or incomplete?"
Those are not separate souls; they are specialized passes—same underlying model family, different instructions and tools—so a research-shaped job and a proof-shaped job don't get collapsed into one fluent first draft.
Together they are supposed to work like a short closed meeting: parallel first takes, then a brief internal cross-check, then one synthesized reply. That is meant to catch sloppy claims the way a second pair of eyes does, not because the system "knows the truth," but because forcing a fact pass and a logic pass to disagree with a first draft is cheaper than hoping one pass is careful.
For people new to this: it is pattern-matching and tool use at industrial scale, not understanding in the human sense. For people who distrust it: the meeting is still generated by the same company, on data and rules you did not choose, and you usually do not see the argument—only the published paragraph. So treat it as a fast, fallible editorial pipeline. Useful when you verify; not an authority because it argued with itself.
