LLM or Deterministic Tool? Route by Uncertainty and Acceptance

A long-scroll visual companion to the article. It summarizes the article evidence boundary and method; it does not extend the underlying result.

Choose a route based on uncertainty, consequence, repeatability, and the acceptance check—not novelty.

Evidence in scope

  • Use code for exact repeatable rules
  • Use interpretation only where needed
  • Define a failure/escalation path

Evidence boundary: A design framework. No paired production speed, quality, or cost comparison is available.

How to use the diagram

State the task contract; route exact cases deterministically; use a model for interpretation with a verifier and human escalation.

What this visual explains: Choose a route based on uncertainty, consequence, repeatability, and the acceptance check—not novelty.

What it does not establish

No universal routing rule or comparative performance result is established.
