Evo-Bench benchmarks nine models on self-improving harnesses — GPT-5.6 Sol tops at +16.6 but Office tasks barely move; MEGA uses a three-layer Wisdom Graph to make agent optimization infrastructure self-evolving, merging knowledge accumulation with optimization; SHE decomposes harnesses into four evolvable components that learn safety boundaries from failure trajectories, cutting ASR by 3.1x with cross-model transferability
