UnverifiedHarness² adopts a two-level recursive mechanism: Level 1 evolves the harness in real time for the current task, and Level 2 evolves the way harnesses are built for future tasks.78% similarUnverifiedDedicated agents are more stable and controllable on specific tasks but have poor scalability, while general-purpose architectures can support multiple vastly different capabilities through the same mechanism but face the risk of task drift.68% similarUnverifiedHarness² uses a Dual recursion mechanism, running optimization loops at both the task level and the framework level.65% similarUnverifiedOne of the core characteristics of agents is the ability to autonomously advance tasks until completion, whereas ordinary large models operate in a turn-based manner.65% similarUnverifiedHarness²'s dual recursion brings computational overhead problems: each task requires multiple rounds of probing and composing, and the framework level also needs to maintain an experience library, placing higher demands on inference cost.63% similar
