LoopArena Benchmark: Models Achieve Only ~25% Success as Loop Engineering Controllers
dair_ai · x · 2026-09-01
LoopArena is a new benchmark evaluating how well models can act as runtime controllers in "Loop Engineering," guiding a fixed coding agent through long-horizon software tasks. Results show that reliable long-term loop control remains challenging, with the best success rate on full tasks around 25%. By decoupling the controller from the worker agent, LoopArena clarifies whether success stems from guidance or execution. Common failure modes include trusting stale progress notes, skipping verification, misallocating budget, and stopping prematurely.
