Can AI Models Direct Each Other? Organizational Structure as a Probe into Training Limitations

arXiv:2603.26458v1 Announce Type: cross Abstract: Can an expensive AI model effectively direct a cheap one to solve software engineering tasks? We study this question by introducing ManagerWorker, a two-agent pipeline where an expensive "manager" model (text-only, no code execution) analyzes issues, dispatches exploration tasks, and reviews implementations, while a cheap "worker" model (with full repo access) executes code changes. We evaluate on 200 instances from SWE-bench Lite across five con
