It's Not the Capability: Harness Sensitivity Is Non-Monotone Across LLM Agent Tiers 事件

It's Not the Capability: Harness Sensitivity Is Non-Monotone Across LLM Agent Tiers arXiv:2605.26731v1 Announce Type: cross Abstract: A prevalent assumption in LLM agent deployment holds that more structured harnesses universally improve reliability, and that higher-capability models need proportionally less structural guidance -- together implying a monotone inverse relationship between model capability tier and optimal harness complexity. We test this hypothesis through a controlled 432
