AI agent harnesses dramatically impact performance, study shows

By PulseAugur Editorial · [2 sources] ·

A recent analysis highlights the significant impact of agent harnesses on AI model performance, demonstrating that changing the harness alone can drastically alter task completion rates. When tested with the same GLM-5.3-flash model on the AppWorld benchmark, different harnesses yielded completion rates ranging from 30% to 81%. While Hermes is suited for personal assistants and Deep Agents for long, multi-step tasks, IBM's CUGA is presented as an enterprise-focused harness designed for rule enforcement and deployment within private environments.
