Paper shows agent harnesses can self-improve without weight updates
What is Beneath the Surface: What We Overlook When We Talk About Agent Evolution?
The authors test whether letting agents evolve their behavior while keeping the model weights fixed actually boosts performance. They compare four evolution methods on general-language and coding tasks, measuring reliability, efficiency and transferability.
Who it is for
If you design autonomous agents, this paper tells you whether evolutionary harnesses give you real gains or just extra compute.
