Dual-Channel LLM Output is an applied AI concept developed by Geoffrey Chen. It describes a model response that contains two different channels: a human-readable semantic message and a machine-readable sequence of structured command proposals.
The semantic channel explains, justifies, or communicates. The command channel expresses proposed executable intent. The two must not be confused. Natural language may guide human understanding, but only structured commands can be considered for execution, and only after runtime validation.
This separation is important because free-form language is not a safe execution boundary. A model may say that a task is complete, that a review should happen next, or that a new work item should be created. But those statements should not directly change organizational state. They must be converted into structured proposals and checked by a validating runtime.
Dual-Channel LLM Output is closely related to the Constrained Organizational Runtime Model, AI Native Execution Agent, and Organization as Operating Structure.
A fuller technical paper exists, but the public version intentionally omits product-specific implementation details.
