Argus beats a direct coding agent 78% vs 59% on SWE-Bench Pro at 1.41x tokens, and gets cheaper as it matures.

arXiv 2608.05144 runs Manager, Planner, Engineer and Reviewer roles over persistent project state with fixed model weights, self-evolving through runtime state and control policies rather than training. 76.8% on AARRI-Bench, and mature waves use 21% fewer solve-input tokens and 15% less active workflow time than startup waves. The reliability machinery is worth copying on its own: 34 verifier recoveries and 22 strict review-loop rescues across 254 missions in six real paper pipelines, with 16 stage rollbacks. Rollback as a first-class primitive is what most home-rolled loops lack.
