Researchers have developed Task-CoEvolve, a novel method to significantly reduce the computational cost of optimizing Large Language Model (LLM) harnesses. This approach adaptively selects validation tasks that are most informative for distinguishing between evolving harness candidates, rather than evaluating a fixed set of tasks at each iteration. By focusing on tasks where candidate harnesses show disagreement and estimating full-set performance from partial evaluations, Task-CoEvolve achieves comparable final performance to traditional methods while cutting evaluation costs by up to 80%. The method has demonstrated effectiveness on benchmarks like Terminal-Bench 2.1. AI
