Run one coding task, one retrieval-heavy long-context task, and one structured extraction task through two providers. Keep the prompt pack identical. If a cheaper route changes answer shape or needs retries, the apparent savings disappear.
For agent workflows, also track tool-call compatibility and failure recovery. A route that is slightly more expensive can still win if it keeps the agent loop predictable.
