When Agents Go Quiet: Output Generation Capacity and Format-Cost Separation for LLM Document Synthesis
arXiv CS.AI

ArXi:2604.16736v1 Announce Type: new LLM-powered coding agents suffer from a poorly understood failure mode we term output stalling: the agent silently produces empty responses when attempting to generate large, format-heavy documents. We present a theoretical framework that explains and prevents this failure through three contributions. (1) We
