Reasoning Brain.

General multi-step reasoning, hypothesis testing, and structured deliberation.

The Reasoning Brain handles open-ended cognitive load: hypothesis generation, multi-step deduction, scenario evaluation, and structured deliberation. It is the brain that thinks for the system. It works closely with the Planning Brain on multi-stage problems and with the Quorum Brain when its conclusions are about to be acted on. It runs on a high-quality reasoning model selected for chain-of-thought stability and tool-use compatibility.
