The Router Waited to See Progress
ProgRouter chooses a model at each workflow step from evolving completion, difficulty and budget signals.
Summary
ProgRouter chooses a model at each workflow step from evolving completion, difficulty and budget signals.
A multi-view scorer tracks outcome regime, subtask completion, progress trends and state quality before a meta-gate estimates the gain from each candidate model. Experiments across coding, mathematics and retrieval-augmented question answering reduced operating cost against stated baselines while maintaining strong task performance; the abstract does not claim one universal saving.
Why it matters
ProgRouter chooses a model at each workflow step from evolving completion, difficulty and budget signals.
