2. Evolve the Harness, Not Weights, to Boost AI Benchmarking

A Hugging Face blog shows freezing a model’s weights while automated harness optimization dramatically improves performance on a legal reasoning benchmark. By rewriting only the runtime harness around the model, the system achieves a sevenfold reduction in cost per task and matches the benchmark’s headline metric, all without changing any weights. The result emphasizes that the bottleneck was the harness, not the model itself. Source-twitter
