ActiveSaddler introduces automated curriculum learning for harness optimization, treating the evolving training curriculum as a non‑stationary bandit problem. It identifies reusable failure patterns, estimates learning progress for each, and balances revisiting known weaknesses with exploring new scenarios, allowing the curriculum to co‑evolve with the harness. Experiments on GAIA2 and Terminal‑Bench 2.0 show consistent improvements in harness performance, with Pass@1 gains of 4.4 and 7.5 percentage points over fixed‑order baselines.

The paper presents a theoretical framework comparing three evolutionary paradigms—Darwinian, Lamarckian, and agent-directed evolution—in the context of AI. It shows that when learning is effective, agent-directed evolution can accelerate adaptation by generating and evaluating behavioral variants, but this speed can also lead to convergence on misspecified objectives. The authors argue that independent evaluation and oversight are essential to ensure that AI’s self-directed improvements remain aligned with intended goals.
