The work targets harness development for building capable AI agents, where earlier RSI methods improved performance but at increased cost.", "body_md": "Harness development plays a crucial role in building capable AI agents. Recent approaches improve harnesses through recursive self-improvement (RSI), but their performance gains often come with higher execution costs.
